Answer :
Final answer:
c) 35-55%
The approximate oxygen delivery range for a simple mask is 35-55%, which varies based on patient needs and mask fit.
Explanation:
The approximate oxygen delivery range for a simple mask is 35-55%. Simple masks are designed to cover the nose and mouth, providing a moderate flow of oxygen to the patient. They are often used in medical settings when patients require a higher oxygen concentration than what is available in room air, but they do not need the precision control of a mechanical ventilator or the high flow rates of a non-rebreather mask. The effectiveness of a simple mask in delivering oxygen efficiently can be influenced by factors such as the fit of the mask on the patient's face and the patient's breathing rate and depth.
