The main concept is assessing how well a patient’s lungs can handle the pressure changes and high oxygen levels during HBOT. Because HBOT involves compressing the breathing gas and increasing the ambient oxygen partial pressure, the lungs must tolerate these conditions without risking barotrauma, reduced oxygen delivery, or oxygen toxicity. Pulmonary function testing helps identify those with underlying lung disease or limited lung reserve who might be at higher risk during treatment, such as obstructive or restrictive patterns or reduced diffusion capacity. If testing shows acceptable lung function and no contraindicating findings, a patient is considered safer to proceed with HBOT; if results raise concerns, clinicians may adjust the plan or explore alternatives. While ENT status and other factors matter for overall safety—since ear and sinus function affect pressure equalization—pulmonary function testing is the emphasized pre-treatment assessment when indicated because it directly gauges the lung’s tolerance to HBOT. Blood type and visual acuity aren’t typically relevant to candidacy decisions.
