Oxygen And Carbon Dioxide Breathing Test

Washington, DC rates for HCPCS 94681

This test measures how much oxygen the body uses and how much carbon dioxide it produces by analyzing the air breathed out, both at rest and often during exercise. It gives a detailed look at how efficiently the lungs and body are exchanging gases, which can help evaluate heart and lung function or overall fitness capacity. It builds on a simpler oxygen-only measurement by also including the carbon dioxide output and the share of oxygen absorbed from each breath.
