Final answer:
Blow-by supplemental oxygen can be provided via a flow-inflating bag-mask-valve. This device delivers oxygen to the patient's airway by inflating a bag that is connected to a mask covering the nose and mouth. It is commonly used in medical emergencies.
Step-by-step explanation:
Blow-by supplemental oxygen can be provided via a flow-inflating bag-mask-valve. This device consists of a mask that covers the patient's nose and mouth, connected to a bag that can be inflated with oxygen. When the bag is squeezed, it delivers oxygen to the patient's airway, providing an oxygen-rich atmosphere to breathe. This method is commonly used in medical emergencies to administer oxygen to patients who are unable to breathe on their own.
