APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -As a general rule, a low pH with a high PaCO2 suggests a respiratory acidosis, while a low pH with a low PaCO2 suggests a metabolic acidosis.

Detailed explanation-2: -The CO2 accumulates in the blood, so PCO2 rises, usually above 45 mmHg. This causes a decrease in blood pH, often reducing it below 7.35. To compensate for this decrease, the body has designed several mechanisms. If the respiratory centers are working, then they try to increase the rate and depth of ventilation.
