Final answer:
Self-inflating bags used in medical emergencies require an oxygen reservoir attachment to deliver a high concentration of oxygen to patients.
Step-by-step explanation:
Self-inflating bags require the attachment of an oxygen reservoir to deliver a high concentration of oxygen. These bags are commonly used in medical emergencies and anaesthesia to provide ventilation to patients who are not breathing adequately on their own.
The oxygen reservoir is typically a small bag or balloon-like attachment that holds a supply of pure oxygen. When the self-inflating bag is squeezed, it draws oxygen from the reservoir, allowing for the delivery of oxygen concentrations ranging from 40% to nearly 100%, depending on the design and how completely the reservoir bag is filled prior to compression.
Self-inflating bags require the attachment of a reservoir bag to deliver a high concentration of oxygen. The reservoir bag helps store oxygen between breaths, ensuring that a consistent and high concentration of oxygen is available for the patient during manual ventilation.
These bags are commonly used in medical settings, such as hospitals and emergency situations, where immediate and controlled delivery of oxygen is crucial for patients experiencing respiratory distress or failure.
The reservoir bag allows healthcare providers to manually assist a patient's breathing while delivering a sufficient amount of oxygen.
