What should be done if oxygen saturation cannot be maintained?

When oxygen saturation cannot be maintained, providing ventilatory support is the appropriate action because it directly addresses the underlying issue of inadequate oxygenation. Ventilatory support can help facilitate the patient's breathing, ensuring that they receive an adequate amount of air and allowing for more effective gas exchange within the lungs. This intervention can be crucial in preventing further deterioration of the patient’s condition.

Automatic oxygen delivery or simply increasing supplemental oxygen may be insufficient if the patient has difficulty maintaining their own ventilation. Supporting the patient's breathing with mechanical assistance or through bag-mask ventilation can help restore proper oxygen levels in cases of respiratory failure or distress.

Transferring to a medical facility is important but usually comes after ensuring the patient’s immediate respiratory needs are addressed. Just administering oral medication would not be effective in restoring oxygen saturation since it does not aid in breathing or improve gas exchange, making ventilatory support the best choice in this scenario.
