Capnography is a reliable method for confirming proper ET tube placement because carbon dioxide is not present in the esophagus.
What is Capnography?
- Capnography is the process in which we monitor the partial pressure of carbon dioxide in the rest of the respiratory gases.
- It monitors an individual during intensive care and anesthesia as it can identify the situations in which hypoxia (oxygen not available) is created and thus helps to prevent them.
- Capnography is a boon for patient safety during anesthesia and CPR.
- Since capnography detects CO2 and CO2 is not present in the esophagus, therefore it is a reliable method for confirming proper endotracheal tube (ETT) placement in the trachea.
- It can also detect if the ET tube has dislodged, by checking ventilation, perfusion etc.
