PACO2stands forPartial Pressure of Carbon Dioxide in Arterial Blood
Full Form of PACO2
What is PACO2?
PaCO2 is a critical measurement in arterial blood gas (ABG) analysis, representing the partial pressure of carbon dioxide dissolved in arterial blood. It reflects the efficiency of pulmonary ventilation and the body's acid-base balance. In India, PaCO2 is routinely measured in intensive care units, emergency departments, and during surgical procedures to monitor respiratory function in patients with conditions such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia, or metabolic disorders. PaCO2 values are interpreted alongside pH, bicarbonate, and PaO2 to diagnose respiratory acidosis, respiratory alkalosis, and mixed acid-base disturbances. Normal PaCO2 ranges from 35 to 45 mmHg; values above indicate hypoventilation (respiratory acidosis) and values below indicate hyperventilation (respiratory alkalosis). For Indian medical students and healthcare professionals, PaCO2 is a core topic in physiology and internal medicine exams like NEET PG, USMLE, and MBBS finals. Its clinical relevance extends to ventilator management, assessing respiratory failure, and guiding treatment in sepsis or diabetic ketoacidosis. Understanding PaCO2 dynamics is essential for accurate diagnosis and patient care in diverse clinical settings across India.

Example
The ABG report showed a PaCO2 of 55 mmHg, indicating the patient was in respiratory acidosis due to inadequate ventilation.
PACO2 — frequently asked questions
What is the full form of PaCO2?
The full form of PaCO2 is Partial Pressure of Carbon Dioxide in arterial blood.
What is the normal range of PaCO2 in adults?
The normal range of PaCO2 in adults is 35 to 45 mmHg.
What does high PaCO2 indicate in an ABG report?
High PaCO2 indicates hypoventilation and respiratory acidosis, often seen in COPD, asthma exacerbation, or sedative overdose.
