Coast Guard Hyperbaric Medicine Practice Test

Pulmonary function tests (PFTs) are essential for evaluating lung function because they accurately assess how well the lungs are working. These tests measure various aspects of lung performance, including the volume of air the lungs can hold, how quickly air can be exhaled, and the efficiency of gas exchange. This detailed information is crucial when considering a patient for Hyperbaric Oxygen Therapy (HBOT), as optimal lung function is essential for ensuring that the increased atmospheric pressure and oxygen levels in HBOT will not exacerbate any existing lung conditions or impair gas exchange.

While other tests like electrocardiograms (ECGs) focus on heart function, X-ray imaging provides a view of lung structure, and blood gas tests measure the effectiveness of the lungs in exchanging gases, these are not as comprehensive in evaluating overall lung function as PFTs. PFTs give a clear picture of a patient's respiratory capacity and efficiency, which is vital knowledge for safe and effective HBOT administration.
