Capnography device tracks the concentration of carbon dioxide in exhaled air, also known as end-tidal CO2 (etCO2). These waveforms can immediately indicate changes in O2 levels, which may be a signal of respiratory distress. CO2 graph monitoring has become increasingly popular in recent years and is considered a standard of care for most outpatient procedures involving moderate or deep sedation.
A capnography device is a machine that measures carbon dioxide exchange through a patient's breathing. At the end of exhalation, a certain amount of carbon dioxide is released, called end-tidal CO2 or EtCO2. As CO2 is transported through the veins to the heart, which then pumps it into the lungs, this measurement can indicate a patient's cardiac output and pulmonary blood flow.
Capnography device measure EtCO2 through either side-stream (diverting) or mainstream (non-diverting) technology. The main difference between these two methods is that the sidestream CO2 analyzer is designed to transport or divert exhaled air through a tube to the sensor, while the mainstream CO2 analyzer does not move the sample but directly analyzes it at the source.
Both sidestream and mainstream CO2 graph devices offer various benefits to healthcare facilities. The benefits of capnography device include shorter response times for mainstream CO2 analyzers as EtCO2 does not have to travel far to reach the sensor, but sidestream CO2 monitors may be more comfortable for patients as the connecting tubing is lighter and smaller than the mainstream version.
End-tidal capnography device: The advent of exhaled CO2 monitoring curves is a major breakthrough in the use of noninvasive technology to detect lung function, particularly pulmonary ventilation. It makes continuous, quantitative monitoring of patients at the bedside possible, especially providing a clear indicator for respiratory support and management for anesthesia, ICU, and respiratory patients. PetCO2 monitoring can be used to evaluate pulmonary ventilation, the patency of the entire airway and breathing circuit, ventilation function, circulatory function, pulmonary blood flow, and minor re-inhalation.
Transcutaneous capnography device: widely used in surgical evaluation, early monitoring of septic shock, determination of diabetes amputation plane, monitoring of free flap blood supply and laparoscopic surgery monitoring, and more.
