Question

Quizplus · Accepted Answer

A nonrebreathing mask at 10 L/min is the best choice to deliver a 70% He:30% O₂ mixture in order to reduce the work of breathing in a patient having an acute asthmatic attack. This delivery system provides the highest concentration of the gas mixture and a flow rate sufficient enough to ensure delivery of the required amount to the patient. The other delivery systems are not adequate for this purpose.
