waveform capnography

Waveform capnography is a technique that measures and visually displays the amount of carbon dioxide (CO₂) in a person's breath over time. It produces a graph called a waveform, which shows the pattern of CO₂ levels during each breath cycle. This tool helps healthcare providers assess how well a person is ventilating (breathing out CO₂), monitor anesthesia depth, and detect problems like airway obstructions or breathing stops. The shape and features of the waveform provide important information about respiratory function and effectiveness, ensuring safe and effective patient care.
