Answer :

It is clearly indicated for patients who present with Respiratory distress.

The quantity of carbon dioxide emitted at the conclusion of an exhaled breath is known as end-tidal carbon dioxide (ETCO2). The extent to which carbon dioxide (CO2) is transported in the blood back to the lungs and breathed is reflected in the ETCO2 levels.

The available research has demonstrated that measuring ETCO2 can indicate pulmonary blood flow and cardiac output. Capnography and capnometry are non-invasive techniques for measuring ETCO2. Capnometry gives an ETCO2 value in numbers.

Capnography, in comparison, provides a more thorough measurement that is shown both graphically (as a waveform) and numerically. Capnography is now the most often advised technique for measuring ETCO2 because of this.
