What is the clinical endpoint for administering oxygen to a patient who has suffered from an injected poison?

The clinical endpoint for administering oxygen to a patient who has suffered from injected poison is a pulse oximetry reading over 94 percent. This is because a pulse oximeter measures the saturation of oxygen in the blood, providing a direct indication of how well oxygen is being transported to the body's tissues. A reading above 94 percent indicates that sufficient oxygen is being delivered to meet the metabolic needs of the body's cells, which is especially crucial in cases of poisoning, where adequate oxygenation might be compromised.

Maintaining oxygen saturation above this threshold helps prevent hypoxia and ensures that the vital organs receive the oxygen required for proper function. In an emergency setting, targeting a saturation below this level could lead to potential complications due to insufficient oxygen, especially since poisons can interfere with the body’s ability to utilize oxygen effectively.

While other options provide various clinical metrics, they do not directly correlate with the safe and effective level of oxygenation desired in the context of treating patients affected by injected poisons.
