What is the purpose of providing 100% oxygen or high-flow oxygen in these emergencies?

• A. To sedate the patient
• B. To increase tissue oxygenation
• C. To treat hyperoxemia
• D. To reduce anxiety

Answer: (B)

Providing high-flow oxygen in emergencies centers on making sure the body's tissues get enough oxygen when breathing is compromised. When breathing is impaired, the amount of oxygen reaching the blood drops, risking tissue hypoxia. Giving 100% or high-flow oxygen increases the oxygen content in the blood by raising the partial pressure of oxygen in the lungs and improving arterial oxygen saturation. This boosts the amount of oxygen delivered to tissues, supporting cellular metabolism and organ function during the crisis. Sedating the patient or reducing anxiety aren’t the primary goals of oxygen therapy, and while excessive oxygen can be harmful in some situations, the immediate aim in an emergency is to correct hypoxemia and improve tissue oxygenation.
