Jul 21, 2025 · A normal capnography waveform has a square shape: sharp upstroke, flat alveolar plateau and a quick return to baseline. This shows that exhaled CO2 is moving out efficiently.

Initially, waveform and EtCO2 value are low during cardiac arrest but increase with effective chest compressions. The higher the EtCO2 value the greater the chance of ROSC. EtCO2 ≥ 20 …

Aug 20, 2025 · A healthy capnography waveform displays a characteristic rectangular shape with rounded corners. This waveform has four phases reflecting carbon dioxide during a breath.

Capnography is an objective monitoring tool for assessing respiratory status in the intubated and non-intubated patient. End-tidal value—peak CO2. ET tube disconnected, 7 dislodged, kinked .

Waveform capnography can provide information over and above a solitary value of exhaled carbon dioxide, and it is important that clinicians at the bedside can interpret the …
