Final answer:
The best way to deflate the balloon on the Pa catheter is to allow the balloon to deflate passively.
Step-by-step explanation:
The best way to deflate the balloon on the Pa catheter is to allow the balloon to deflate passively.
Passive deflation occurs when the pressure inside the balloon decreases naturally without any external force applied. In the case of the Pa catheter balloon, it is designed to deflate on its own when the pressure in the surrounding fluid decreases.
This happens, for example, when the balloon is no longer in contact with blood or when an external source of pressure is removed.
