What is the primary focus when using emergency oxygen delivery systems?

The primary focus when using emergency oxygen delivery systems is effectiveness in treatment. In diving emergencies, such as decompression illness or hypoxia, providing sufficient oxygen rapidly and efficiently is critical to mitigate potential life-threatening conditions and improve recovery outcomes. Oxygen acts to support cellular metabolism and combat the effects of inert gas bubbles formed during decompression, making its timely and effective administration vital for the wellbeing of the affected individual.

While convenience, speed, and cost are also considerations in the selection and usage of oxygen delivery systems, they are secondary to the primary goal of ensuring the patient's health and safety. Effectiveness in treatment is paramount, as the correct application of oxygen therapy can prevent long-term damage and improve the chances of survival.
