Summary Introduction
To analyze:
The acid base status of Henry and the compensation report, who has suffered from a severe myocardial infarction and the lab reports from an arterial blood sample show the values as pH as 7.30, HCO3- (bicarbonate ion) as 20 mm (millimeter) Eq/liter (equivalents per liter), and
Introduction:
Myocardial infarction is a cardiac disorder in which there is a low or no blood flow to the heart and causes damage to the cardiac muscles.

Henry is in the intensive care unit because he suffered a severe myocardial infarction three days ago. The lab reports the followingvalues from an arterial blood sample: pH 7.30, HCO320 mEq/ liter, PCO2 32 mmHg. Diagnose Henry’s acid–base status and decide whether compensation is occurring.
Adult male suffered myocardial infarction and is currently in cardiogenic shock. Blood pH = 7.25, [HCO3-] = 14 mmol/L, PaCO2 = 38 mmHg.
What kind of acid-base imbalance is the patient suffering from? Briefly describe fully how this occurred.
A normal saline solution (0.9 mg of sodium chloride per 100 ml of solution) is given intravenously and a total of 0.5 L of the solution was given over a 4 hour period.
What is the flow rate in units of milliliter per hour?.
What is the flow rate in units of mg ( of sodium chloride) per hour?.
During 4 hour period how much sodium chloride is delivered?

She reports to the ED in the early morning with shortness of breath, blurred vision, headache, and restlessness. After several laboratory tests, the following ABG (arterial blood gases) lab results are confirmed: Blood pH=7.30 PaCO2 = 46 mm Hg HCO3 = 24 mEq/L. Based on the results of her ABG, which acid-base imbalance is Mrs. Breathless likely experiencing? Justify your answer by referencing the ROME mnemonic.
