Oxygen-Induced Hypoventilation Flashcards

Vocabulary flashcards covering the pathophysiology of oxygen-induced hypoventilation, COPD respiratory drives, and the symptoms of CO2 narcosis.

Normal drive to breathe

A respiratory stimulus based on increased $CO_{2}$ levels.

COPD respiratory drive

A drive to breathe based on low $O_{2}$ levels due to chronic $CO_{2}$ retention.

Oxygen-Induced Hypoventilation precaution

The practice of using oxygen cautiously in COPD patients by starting at the lowest possible $O_{2}$ needed to achieve the desired $SpO_{2}$ goal.

Hypoxia lethality timeline

A condition that kills in seconds to minutes.

CO2 narcosis timeline

A condition that takes hours to develop.

Symptoms of CO2 narcosis

Drowsiness, irritability, hallucinations, convulsions or coma, tachycardia, and arrhythmias.
