  1. Mr. B is a 70-year-old man who developed sub sternal chest pains radiating down his left arm while at home. He was taken to the ER via ambulance. His breathing was labored, pulses rapid and weak, and his skin was cold and clammy.An ECG was done which revealed significant “Q” waves in most leads. Troponin level was elevated. Arterial blood was draw with the following results:

Ph 7.22

PCO2 30 mm

Hg pO2 70 mm

Hg O2 sat 88%

HCO3 22 meq/liter

  1. Aside from the obvious diagnosis of MI, what is Mr. B’s acid base status and what caused this disturbance?

    • Mr. B’s acid base status would suggest respiratory acidosis .Looking at his arterial blood result the PH is low and his HCO3 is elevated. Respiratory acidosis can be chronic and acute due to his age and the body distribution of body fluid. “Respiratory acidosis occurs when the alveolar hypoventilation, causing Hypercapnia which is excessive carbon dioxide in the blood” Huether, McCance & Brashers (2010).     With physiological aging regulation of the PH depends on the kidney and lung and these two organs is deceased with physiological aging (Nabata T, et al, 1992) The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.  According to Epstein &Singh (2011) treatment for respiratory acidosis may include invasive or noninvasive ventilator support and specific medical therapies directed at the underlying pathophysiologyEpstein SK, Singh N.

A lot of times in the elderly the acid base is overlooked because there is not a different scale for pediatrician, adult versus the elderly so the PH remained the same despite which age group The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.

    • I believe that Mr. B’s acid base status is metabolic acidosis with respiratory compensation in the form of hyperventilation. When determining his acid base status, I looked at his levels of certain arterial blood gases (ABGs). To determine acidosis or alkalosis, I looked at what his arterial pH was, 7.22. With the normal range for pH being 7.35-7.45, Mr. B appears to be in acidosis. However, when I continued to analyze the numbers, noting that his PCO2 was 30 mmHg and HC03 was 22, I was somewhat confused. Since HCO3 is within normal limits of 22-26 mEq/L (Verma & Roach, 2010), it became harder for me to determine acid base status, since HCO3 is what helps determine whether or not it is a metabolic event. However, after continuing my research, I was able to find multiple sources that discussed the correlation between myocardial infarction (MI) and metabolic acidosis. I was able to find that during an MI, due to decrease in cardiac output and arterial hypoxemia, tissue hypoxia occurs, which leads to a rise in lactic acid and metabolic acidosis (Gandhi & Akholkar, 2015). The levels of lactic acid rise due to the decrease in systemic blood flow caused by the MI (Weil & Tang, 2011).Gandhi, A. A., & Akholkar, P. J. (2015). Metabolic acidosis in acute myocardial infarction. International Journal of Advancement in Medicine, 2(3), 260-263. http://dx.doi.org/10.18203/2349-3933.ijam20150556  Huether, S.E., McCance, K.L., Brashers, V.L.

    • However, Mr. B’s situation is not just that simple because his PCO2 level is low, which at first glance would be characteristic of alkalosis (Huether, McCance, & Brashers, 2020). Since in the description of Mr. B’s symptoms it was noted that he is having labored breathing, he could be compensating for the metabolic acidosis by hyperventilating in an attempt to blow off CO2 and raise his arterial pH.

    •      Understanding clinical presentations due to changes at the cellular level will enable you to skillfully care for your patients in diverse practice settings.  In evaluating Mr. B’s acid base balance, we see that Mr. B is in metabolic acidosis with compensation.  Metabolic acidosis can occur rapidly in the case of lactic acidosis or slowly in the case of renal failure, diabetic ketoacidosis, or starvation (Heuther, McCance and Brashers, 2020).  To understand specific types of acidosis, we can look at the anion gap.  Goldberger, AL.

    •      In our case study, we are told Mr. B is having a myocardial infarct (MI); the cause of his acid base disturbance is most likely lactic acidosis from tissue hypoxia due to arterial occlusion from a blood clot.  His hyperventilation is a compensatory response to rising acidosis; the body’s intrinsic balancing act is to blow off acid through an increased respiratory rate.  The q wave in his ECG seen in “most leads” may be an indication of a previous myocardial infarction (MI), but we need more information about the q wave presentation including which leads the q wave is present, and the height and width of the q wave in order to make a diagnosis (Goldberger, 2017).  Treatment for Mr. B will initially be aimed at saving myocardial tissue and quickly reversing acidosis before decompensation and organ damage occurs The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.

    •        Since the blood PH is low and the PCO2 is also low, it is understood that the acidosis was not caused by any respiratory factors but by metabolic processes within the body. According to Huether et al. (2020), an instance of primary metabolic acidosis is an individual experiencing DKA (diabetic ketoacidosis acidosis) from lack of insulin secretion or administration. Mr. B may have issues where he lacks insulin, or he cannot metabolize glucose. Mr. B’s body metabolizes store fat and, as a result, creating acid as a byproduct. According to A.T Howarth (1970), metabolic acidosis appears to be due to the increase of lactic acid. The lungs attempt to compensate by Kussmaul respiration.

    • Huether et al. (2020) affirm that pathophysiology is essential in grasping disease mechanisms and examining how a modification to one’s body structure may impact their functionality and reveal the signs and symptoms of an ailment. Mr B’s case is an example of a patient that could have multiple diagnoses despite similarities in the disease indications. Mr B likely has respiratory acidosis in which the blood ends up acidic since not all the carbon dioxide is eliminated from the lungs. The condition occurs due to various reasons such as the diseases in one’s airways, pulmonary fibrosis, scoliosis, incompatible medications, obesity, and obstructive sleep apnea among others. In Mr B’s case, the remaining CO2 caused a reduction in the pH. levels of the body fluids and thus the acidity. The patient has metabolic acidosis due to the pH level of 7.22 and the bicarbonate level of at 22 mEq/liter The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays. The former may be normal but the difference between the HCO3 and the PCO2 levels makes the illness to be respiratory due to elimination of normalcy. The oxygen reduction also results in the patient being hypoxemic as blood will not be sufficiently supplying oxygen to the body tissues.References     Pathophysiology 7th ed.  Elsevier Mosby.Surat, P.

    • His situation was likely linked to his myocardial infarction that caused the labored breathing, weak yet rapid pulses, and the chest pains. In a normal setting, the body fluid’s pH levels should be about 7.35 to 7.45, the pCO2 should be between 35-45, and the HCO3 should be at about 22-26 (P, 2018). Again, the Hg PO2 ought to be at 80-100mm and the oxygen pressure at 90-100%. Evaluating these components is critical in maintaining the acid-base status of body fluids (Schück & Matoušovic, 2015). Mr B should treat his condition by opting for bronchodilator drugs to curb the effects of the obstruction in his airways. Secondly, he should consider a breathing machine or a Continuous Positive Airway Pressure (CPAP) therapy. Also, he should have an adequate oxygen supply especially when there is a reduction of the oxygen levels in his blood.

    • Mayo Clinic (n.d) states that when experiencing a myocardial infarction patients can experience labored breathing, just like Mr. B.  The labored breathing is most likely due to poor perfusion and hypoexmia.  The body’s decreased ability to adequately perfuse and get the adequate amount of oxygen into the blood stream can consequently cause acid to build up, causing metabolic acidosis (Huether et al, 2020).  Metabolic acidosis when defined in its most simplest form is, the build up of acid in a person’s body fluids (Medline Plus, 2021).  Mr. B’s arterial blood gas shows a pH of 7.22, this is considered acidic and lower than the expected range. Mr. B’s PCO2 was 30 mm, this is also below an acceptable standard, and considered to be acidic. When a patient’s pH and PCO2 falls below the acceptable range they are then considered to have an acid-base imbalance, specifically metabolic acidosis.

    • Acute myocardial infarction (MI) produces tissue hypoxia resulting in an acid base imbalance secondary to the decrease in cardiac output and arterial hypoxemia (Gandhi & Akholkar, 2015). Mr. B, a 70-year-old gentleman experiencing a sudden MI displays this imbalance given his arterial blood gas (ABG) of pH: 7.22, pCO2: 30mm, and HCO3: 22 mew/L. This ABG shows the patient is in an uncompensated metabolic acidosis. The patient also presented with significant “Q” waves in most leads. According to MacAlpin (2006), a ‘Q’ wave abnormality has an indication of cardiac disease or coronary heart disease with MI and generally this is the chronic stage of an MI. It is also found that Q waves are associated with ventricular hypertrophy. When this patient experiences an MI there is a hypoxic injury to cardiac tissue. The body responds within minutes when there is a mitochondrial compromise. Then there is an insufficient production of Adenosine Triphosphate (ATP) which results in a loss of contractility of the heart, further decreasing the cardiac output. This loss of contractility is a result of the rapid decrease in mitochondrial phosphitylation. When this occurs, anaerobic metabolism generates ATP from glycogen. However, when the glycogen is depleted even anaerobic metabolism ceases as well (Heuther, McCance, & Brashers, 2020)Metabolic Acidosis can be severe, specifically in those with profound cardiogenic shock secondary to an MI (Gandhi & Akholkar, 2015). Gandhi & Akholkar (2015), also found that there was a link between the patient experiencing an MI’s admitting pH level and their mortality rate. They found that those with a pH <7.35 were statistical more likely to die. Similarly they found that these patients who had a HCO3 level of <22 were also more likely to develop ventricular dysrhythmias and more likely to die (Gandhi & Akholkar, 2015). Since acidosis has been shown to have an increased mortality rate, Lazzeri, Valente, Chiostri, Picariello, & Gensini (2010), suggest the use of the anion gap to show more subtle changes in the degree of acidosis to assist with predicting patient outcomes..ReferencesHeuther, S.

    • So, in short review of the case study, Mr. B. developed the chest & left arm pain secondary to the referred pain from his MI. His breathing became labored secondary to two reactions. First the decreased cardiac output increased the oxygen demand of all tissues thus his body began to compensate with increased respirations. Furthermore the labored breathing was also a result of the body’s compensation for the acidosis trying to blow off excess HCO3 (an acid). Mr. B.’s pulses were weak from his decreased cardiac output most likely from the decreased contractility of his heart from the decreased ATP production secondary to hypoxia. The decreased cardiac output further more caused his skin to become cool and clammy from decreased peripheral circulation and most likely hypotension.
    • A failure of the sodium (Na+) potassium (K+) pump and Na+ Calcium (Ca+) exchange occurs with this prolonged hypoxia and resulting mechanisms. This causes Na+ and Ca+ into the cells causing it to swell and K+ out of the cells into the extracellular fluid. Without the sodium/potassium pump, there is free movement of sodium and water. Because of the shifting of electrolytes, the patient enters metabolic acidosis. The treatment for this process is to correct the hypoxia. Without fixing the hypoxia a process known as vacuolation and eventually cell death will occur. Decreased protein synthesis and calcium accumulate within the cell, the cell membrane becomes dysfunctional and the influx of calcium in the cells triggers a pro apoptotic protein causing cell apoptosis (Heuther, S.E., McCance, K.L. & Brashers, V.L., 2020).

    • Arterial blood gas (ABG) measurements are collected for the assessment of ventilation, oxygenation, and the acid-base status of the body. The levels of pH, oxygen (O2), carbon dioxide (CO2), and bicarbonate (HCO3) are measured in arterial blood. Interpretation of ABG results allows for assessment of acid-base imbalances. “Slight changes in the amounts of hydrogen and changes in pH can significantly alter biologic processes in cells and tissues” (Brenneman & Huether, 2020, p. 123). Ranges for normal and abnormal lab values can vary based on where the measurements were conducted The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays. Pompey & Abraham-Settles (2019) provide their interpretation of normal ABG values, “four values are used in ABG analysis: pH, PaCO2, HCO3, and PaO2” (p.53). Normal ABG values:  pH: 7.35-7.45, PaCO2: 35-35 mm Hg, HCO3: 22-26 mEq/L, PaO2: 80-100 mm HG.Elevation of PaCO2 with decreased pH, indicates respiratory acidosis. PaCO2 decrease with elevated pH, indicates respiratory alkalosis. HCO3 values are normal with respiratory imbalances. Elevated levels of HCO3 along with increased pH, indicates metabolic alkalosis. Decreased HCO3 along with decreased pH, indicates metabolic acidosis. Hypoxemia may be present if PaCO2 Level is decreased during a metabolic disturbance.The patient’s presentation can provide some background into acid-base imbalance. His cardiac and respiratory distress, signal signs of metabolic acidosis, in form of rapid pulse rate and labored breathing. Hypoxia noted as evidence by the patients’ presentation, as well as, decreased PaCO2 level.I feel the cause of metabolic acidosis is possibly due to ketoacidosis or lactic acidosis. In the case of normal anion gap, unable to be assessed due to unknown values, the possible cause could be gastrointestinal related or renal related. I also thought of mixed acid-base imbalance, respiratory alkalosis. Respiratory alkalosis secondary to metabolic acidosis, in response to hyperventilation, which is seen lactic acidosis  Huether, S.

    •  To find the cause of metabolic acidosis, anion gap needs to be determined. Anion gap is resulted by finding the sum of chloride (Cl) and HCO, which is then subtracted from cation sodium (Na). In this patients’case the Na and Cl are unknown. Normal values for Na 140, Cl 103, known value of HCO3 22. Using the anion gap formula 140 Na – [103 Cl+ 22 HCO3}is approximately 15, suggesting elevated anion gap, with normal values of approximately 10-12 mEq/L. Elevated anion gap in metabolic acidosis is indicative of possible ketoacidosis, lactic acidosis, ingestion of certain substances and renal disorders

    • After assessing the provided lab values, I determined the acid-base imbalance to be metabolic acidosis, demonstrated by abnormal lab values of 7.22 for pH and 30 mm Hg for PCO2. It is noted that the HCO3 value remains in normal range, this is where things became confusing. According to Brenneman & Huether, (2020), when pH is low and PaCO2 is “normal or low, acidosis is not caused by respiratory factors. Instead, it is caused by metabolic processes within the body” (p. 128). However metabolic acidosis is said to be present with decreased pH and decreased HCO3. Our textbook appears to display decreased levels of HCO3 as less than 22 mEq/L, so for our purposes the patient’s lab values for HCO3 appear normal The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.
    • PaO2 produces information relating to the person’s oxygenation status, however it does not assist in determining acid-base status. The measurement of blood pH, PaCO2 and bicarbonate level simultaneously, provides information on the acid-base status. Blood pH below normal values indicates acidity and values above normal indicate alkalinity.  The measurements of PaCO2 and HCO3 tells us the source of the imbalance, respiratory issue or metabolic issue. Abnormalities in PaCO2 signals a respiratory problem, as abnormal values in HCO3 indicate a metabolic problem.

    • In this case study, Mr. B’s acid-base status is metabolic acidosis, which is partially compensated. Compensation is the body’s attempt to correct the pH levels by manipulating the carbon dioxide or the bicarbonate levels. Full compensation is when the pH is returned to the normal range. It is partially compensated because Mr. B is lowering his CO2 levels by hyperventilating, also known as Kussmaul respirations (Pompey & Abraham-Settles, 2019). Kussmaul respirations are deep and fast so they expel large amounts of CO2 from the body. Along with decreased CO2 levels hyperventilating can cause an O2 deficit and hypoxia.References  Pompey, J., & Abraham-Settles, B. (2019).

    • This disturbance in acid-base is caused by an increase in lactic acid. The heart is in a state of stress since an occlusion is causing an increase in cardiac pressure and a decrease in cardiac output. In times of stress, lactic acid acts as fuel to the heart as it can account for accelerated glycolysis (Lazzeri et al., 2015). This creates energy for the heart to effectively perfuse vital organs during the MI.

    • Several physiological mechanisms during a myocardial infarction leading to hypoxia and hypoperfusion.  Poor perfusion and decreased cardiac output causes ATP production to decrease and induce anaerobic metabolism.  Metabolic acidosis occurs from the retention of lactic acid. Dysfunction of the sodium-potassium pumps causes retention of sodium in the cells and potassium out of the cells (Meng-Yu et al, 2018) The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.
    • Arterial blood gas values are used to assess ventilation, oxygenation and the acid-base status of a patient. When the pH is less than the normal value of 7.35, the indication is acidosis. (Pompey & Abraham-Settles 2019). PCO2 of 30 is lower than the normal range of 35-45 mmHg, HCO3 of 22 is on the low normal range of 22-26 mEq/L. This interpretation is compensated metabolic acidosis (Pompey & Abraham-Settles 2019). The respiratory system is compensating for the metabolic problem by labored breathing.

    •          Based on Mr. B’s acid base status, he’s having metabolic acidosis. Disruption in the balance of plasma acidity is known as metabolic acidosis (Burger & Schaller, 2020). During metabolic acidosis, the level of pH and bicarbonate decreases (Matyukhin, Patschan, Ritter, & Patschan, 2020). A pH range that’s <7.35 is an indication of Acidemia. Alongside that, pCO2 level of <40mm, and HCO3 value of <24 mEq/L, show signs of metabolic acidosis (Burger & Schaller, 2020). Mr. B’s lab results have a low level of pH, pCO2, and HCO3. Some of the causes of metabolic acidosis can include: uncontrolled diabetes mellitus, hypoxia, sepsis, and GI related complications (Matyukhin et al., 2020). Mr B’s signs and symptoms indicate that he is having hypoxia, his O2 saturation in his blood is low. Additionally, loss of bicarbonate, and diabetic ketoacidosis, are some of the causes of metabolic acidosis (Burger & Schaller, 2020). Moreover, the results of metabolic acidosis can lead to acute kidney failure (Matyukhin et al., 2020). Some of the treatments for metabolic acidosis are, fluid therapy, administration of medications (such as vasopressors), renal replacement therapy, and management of sepsis (if/when needed) (Matyukhin et al., 2020).  Burger, M., & Schaller, D.

  • Mr. B’s acid base status is currently metabolic acidosis caused by poor perfusion and hypoxemia. “Tissue ischemia/reperfusion injury, hypoxia, and free radicals all contribute to acidosis” (Lin, et al., 2016). This condition can be caused by changes to the cardiovascular system, and manifestations include Kussmaul respirations, and an overall feeling of lethargy (Huether, McCance & Brashers, 2020). Metabolic acidosis can happen quickly, or it can develop over time. Metabolic acidosis is a result of the blood being too acidic (pH less than 7.40), and not enough bicarbonate HCO3 <22 (Huether, McCance & Brashers, 2020). Mr. B also has abnormal levels of CO2 and decreased oxygenation. The body reacts to this change by breathing deep and rapid, which is called hyperventilation; this is an attempt to expel excess carbon dioxide. Berend further comments on this change by stating “In the presence of an acid–base disorder that alters pH, physiological processes occur that tend to restore pH to normal. These changes are considered compensatory. For instance, a metabolic acidosis causes immediate hyperventilation, and a new steady-state Paco2 is reached within hours” (2018). Treatment of this condition is based on what caused the disturbance and correcting it. Since we know that Mr. B is experiencing a myocardial infarction, treatment of metabolic acidosis would focus on treating this MI. In evaluating the cause of the acid base disturbance, the serum anion gap should also be assessed. The specific type of acidosis can be determined by the anion gap and can also help determine the cause of it (Huether, McCance & Brashers, 2020).Berend, K. (2018).

  • After analyzing Mr B’s case his acid base status is metabolic acidosis with partial compensation. His myocardial infarction has decreased his cardiac output leading to his diminished oxygenation (Gandhi & Akholkar, 2015). This hypoxemic state leads to lactic acidosis in the body which can cause metabolic acidosis.  Decreased blood flow to the heart can also lead to myocardial ischemia which will produce some of the clinical manifestations like chest pain that radiates to the neck and arm. The body compensates cardiac ischemia by releasing angiotensin II which triggers vasoconstriction, fluid retention, and coronary spasm in the body (Huether, McCance & Brashers, 2020, p. 608). During ischemic injury, some cardiac cells may die so enzymes like CPK-MB and troponin will be released and later detected in the blood analysis. According to Koivula et. al., “Q waves are the hallmark of myocardial necrosis, but they may also represent reperfusion” (2019).  Unfortunately, when normal blood flow is restored to the damaged area of the heart this reperfusion can aggravate the injury further also leading to Q waves. Luckily, the heart will undergo some wound repair, but it will not contract like before.Gandhi A. A., & Akholkar P. J. Metabolic acidosis in acute myocardial infarction.

  • Module 1, Discussion 2Mr. B has had an MI, which has caused his acid-base status to be unbalanced.Ph 7.22Hg pO2 70 mmHCO3 22 meq/literAnalyzing the five Arterial Blood Gas (ABG) components mentioned above will help to determine what may have caused this disturbance. Pietrangelo (2017) explains the blood requires the right balance of compounds of acid and basic (alkaline) in order for it to function properly. This is known as acid-base balance. The organs working to maintain acid-base balance are the lungs and the kidneys. Vital organs can be significantly impacted when the acid-base balance is even slightly out of the normal range.
    1. The first component of the ABG is the pH. Mr. B’s pH is 7.22 – normal values are 7.35 -7.45. A low pH indicates Mr. B has too much acid in his blood, causing acidemia.
    2. Mr. B’s pC02 value is 30 (normal values are 35-45). Decreased pC02 can be caused by hyperventilation (Rienecke, 2017). Mr. B’s breathing is labored, and he is having chest pain. Labored breathing and pain can cause low pC02.
    3. Mr. B has a p02 value of 70, the normal range is 75-100. This value shows how much oxygen is in the blood. Interestingly enough, Huether et al (2020) the p02 value has nothing to do with the acid-base balance. It provides information on the person’s oxygenation level.
    4. Mr. B’s HC03 value is 22, which is on the low side of normal. HC03 is the bicarbonate level in the blood and is the main component that regulates the pH. High or low HC03 is an indicator of how much the kidneys are compensating. Because the value is still within normal limits, there is not much renal compensation at this point. It could take days for the kidneys to show stress.
    5. Mr. B’s final lab value is the 02 saturation of 88%. Due to the acid-base imbalance, he is not getting enough oxygen and should be placed on oxygen The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.

    Because Mr. B was having an acute MI, this could result in a buildup of lactic acid, which can result from tissue ischemia (Burger & Schaller, 2020), contributing to metabolic acidosis.Burger, M., & Schaller, D. J. (2020). Stat Pearls. Treasure Island.Huether, S. E., McCance, K. L., & Brashers V. L. (2019). Understanding pathophysiologyRienecke, K., (December, 2018). The Effects of pC02 on Respiration.

  • When there’s an acid base imbalance, this may be the result of either a respiratory or a metabolic system process. The respiratory system can quickly balance pH levels by simply increasing or decreasing respiratory rates. Hyperventilation, or labored breathing, in particular causes a decrease in carbon dioxide as a form of respiratory compensation (Pompey & Abraham-Settles, 2019). This is evident in this scenario as his Mr B’s pH level is acidic at 7.22, and PCO2 (carbon dioxide level) is low at 30mm. Mr B’s respiratory system is trying to balance the pH by breathing out the CO2. In this case, he is likely experiencing metabolic acidosis.ReferencesPompey, J., & Abraham-Settles, B.

  • Research by Gandhi and Akholkar (2015) describes what may have caused the pH disturbance. During a myocardial infarction, cardiac output is decreased and arterial hypoxia (low blood oxygenation concentration) occurs which results in tissue hypoxia, metabolic acidosis, and decreased bicarbonate levels due to a rise in lactic acid. This falls in line with the scenario, as his pO2 is 70mm and his O2 sat is 88%, indicating hypoxemia; however, in this scenario his HCO3 (bicarbonate) levels are normal at 22 meq/liter. Hypoxia is likely what caused the rise in acidic levels The Cell, Inflammation, Repair, Regeneration, and Fibrosis discussion essays.
