Final answer:
The typical volume rate for a Simple Mask in respiratory therapy is 15-20 L/min. Proper flow rates help regulate alveolar ventilation, oxygen delivery, and carbon dioxide removal.
Step-by-step explanation:
The typical volume rate for a Simple Mask in respiratory therapy is B) 15-20 L/min. This flow rate is sufficient to ensure that the exhaled gas is flushed out of the mask and the patient is inhaling a high enough concentration of oxygen. The simple mask is a device used in respiratory therapy to deliver a relatively high concentration of oxygen, and it's important that the flow rate is set properly to maintain the desired oxygen therapy.
Adjusting the flow rate of oxygen is crucial for the work of breathing as it helps regulate the balance between oxygen delivery and carbon dioxide removal from the alveoli.
