What does the acronym "PACO2" refer to?

• A. Partial pressure of carbon monoxide in arterial blood
• B. Partial pressure of carbon dioxide in arterial blood
• C. Partial pressure of oxygen in capillary blood
• D. Percentage of air in the lungs

Answer: (B)

The term "PACO2" specifically denotes the partial pressure of carbon dioxide in arterial blood. This measurement is crucial in assessing a patient's respiratory status, particularly in relation to their ability to expel carbon dioxide effectively. An elevated PACO2 can indicate hypoventilation or impaired gas exchange in the lungs, while a decreased PACO2 may suggest hyperventilation. Monitoring PACO2 is essential for diagnosing and managing a variety of respiratory conditions, including chronic obstructive pulmonary disease (COPD) and asthma, as well as determining the effectiveness of interventions that impact a patient's ventilation.
