When should caution be used with oxygen therapy?

• A. In cases of severe asthma attacks
• B. In situations where the patient is unconscious
• C. In cases of COPD or other respiratory conditions where high flow oxygen can be detrimental
• D. In cases of cardiac arrest interventions

Answer: (C)

Caution should be used with oxygen therapy particularly in cases of COPD or other respiratory conditions where high-flow oxygen can be detrimental due to the risk of oxygen toxicity and the potential suppression of the respiratory drive. Patients with COPD often have a prolonged history of high carbon dioxide levels and rely on hypoxia as a drive to breathe. Administering high-flow oxygen can lead to a decrease in their respiratory drive, which could result in insufficient ventilation and worsen their condition. In contrast, while oxygen administration is critical in many situations such as severe asthma attacks or unconscious patients, these situations typically necessitate immediate oxygen support without the same caution as in COPD cases. In the event of cardiac arrest, the focus is generally on immediate resuscitation measures rather than the specific risks associated with oxygen therapy itself.
