The article discusses the advantages of using noninvasive capnography in monitoring the ventilatory status of patients. Compared to a transcutaneous carbon dioxide (tcCO2) monitor, which approximates arterial CO2 detected through the skin, capnography approximates arterial CO2 by directly measuring exhaled CO2. Time-based capnography is the described as the easiest and least expensive form of capnography. Volumetric capnography can provide more ventilatory information and is best suited for constant monitoring of intubated patients.
