Answer:
We can determine that there is a small air leak or not by Connecting to an underwater seal.
Explanation:
It is difficult to determine an ongoing leak in a Heimlich valve without connecting it to an underwater seal. The procedure of underwater seal is conducted by placing the Heimlich valve into a cup of water or in a water seal chamber. Then the presence of air leak is checked if the leakage continues after lung expansion.
This one-way valve system is used to treat spontaneous pneumothorax without hospital re-admissions. A Heimlich valve is a one-way rubber flutter valve which allows air evacuation without tension. Hence, its leakage can be checked during lung expansion by not connecting it to a suction device but actually to an underwater seal.
