Final answer:
The question pertains to the operation of a manual resuscitation bag (BVM) and how to troubleshoot issues such as the bag filling rapidly and collapsing easily. To fix such issues, one should check for leaks, ensure correct connections, inspect for damage, and possibly replace the BVM if malfunctions persist.
Step-by-step explanation:
The question is concerning the operation and troubleshooting of a manual resuscitation bag, also known as a Bag Valve Mask (BVM), that is self-inflating. The flow needed for a BVM typically depends on the manufacturer's specifications and patient requirements, usually ranging between 10-15 liters per minute to achieve adequate oxygen delivery. When setting the FiO2, or fraction of inspired oxygen, the use of a reservoir can increase the FiO2 up to 100%, while without it, the FiO2 may range from 40% to 70% depending on the patient's breathing pattern and the device.
In the scenario where the bag fills rapidly and collapses easily with minimal pressure, one should troubleshoot by checking for any leaks or obstructions in the valve system. Ensure that the bag is properly connected to the oxygen supply and that the oxygen flow rate is correctly set. Inspect the bag for damage or wear and replace it if necessary. If the problem persists, it might be due to excessive compliance of the bag or a malfunctioning one-way valve, requiring further investigation or equipment replacement.
