Acid Base II (Pulmonary)

These flashcards cover essential vocabulary and concepts related to acid-base disorders as outlined in the lecture notes.

PaCO2

Partial pressure of carbon dioxide in arterial blood, a critical indicator of respiratory function.

HCO3‐

Bicarbonate ion, an important buffer in the blood that helps maintain pH balance.

Respiratory acidosis

Condition caused by insufficient ventilation leading to increased CO2 and decreased pH.

Renal compensation

The kidneys' ability to adjust bicarbonate reabsorption to compensate for disturbed acid/base balance.

Metabolic acidosis

Condition resulting from an accumulation of acids or loss of bicarbonate, leading to decreased pH.

Respiratory alkalosis

Condition caused by excessive ventilation leading to decreased CO2 and increased pH.

Metabolic alkalosis

Condition characterized by loss of body acids resulting in increased pH.

Compensation

The body's physiological mechanisms to counteract disturbances in acid/base balance.

Time frames of compensation

Respiratory compensation occurs within seconds to minutes, while renal compensation takes hours to days.

pH

A measure of acidity or alkalinity of a solution, with normal human blood pH typically around 7.4.
