Mr. Adam is in the ICU on an FiO₂ of 100%. An arterial blood gas reveals the following information: pH of 7.18, PaCO₂ of 59, PaO₂ of 65, HCO₃- of 24. What action would you recommend?

a. Provide ventilatory support
b. Put patient on steroids
c. Give patient chest PT
d. Put patient on CPAP

Final answer:

Based on the arterial blood gas results, Mr. Adam should be put on Continuous Positive Airway Pressure (CPAP) therapy to improve ventilation and oxygenation.

Step-by-step explanation:

To recommend an action based on the information provided, it is necessary to analyze the arterial blood gas results of Mr. Adam. The pH of 7.18 indicates acidosis, as it is below the normal pH range of 7.35-7.45. The PaCO₂ of 59 suggests the presence of respiratory acidosis, as it is above the normal range for males (35-48 mm Hg). As for the PaO₂ of 65, it is within the normal range (80-100 mm Hg). The HCO₃- of 24 is also within the normal range (22-29 mM).

Based on these results, it is evident that Mr. Adam is experiencing respiratory acidosis without evidence of compensation. The high PaCO₂ indicates an inadequate elimination of carbon dioxide by the lungs, leading to an accumulation in the blood. One potential action to recommend is to put the patient on Continuous Positive Airway Pressure (CPAP) therapy. CPAP helps improve ventilation and oxygenation by providing constant positive pressure in the airways, which can assist in reducing the PaCO₂ levels and improving overall respiratory function.
