End-Tidal CO2 In Operating Room Environment Analysis

Use of End-Tidal CO2 in Operating Room Environment The wide use of capnometry across hospital settings has evolved to be an industrial tool for identifying potential breathing complications among patients (hyperventilation, hypoventilation, or apnea). ETCO2 is the only non-invasive monitor that is used in “real time” providing instant indication to physicians, paramedics and other healthcare professionals alike. Registered nurses have adapted to use this device for determining if a nasogastric tube has been placed appropriately-- in the esophagus or the trachea. So, one may ask what is capnometry? It is the maximal concentration of carbon dioxide at the end of each exhaled breath illustrated in wavelength form on a x and y axis grid. The waveform…show more content…
One of the many benefits is monitoring the effectiveness of CPR that is favored among paramedics, continuous monitoring in Emergency Rooms and ICU during ambulatory transport for confirmation of accurate placement of ETT (endotracheal tube). It offers a rapid alarm for ventilator disconnection which is identified by a flat line on the capnogram. It also provides an early warning signs of shock, displaying a decreased numeric value in ETCO2. This has implications with any patient that is at risk for shock, especially trauma and cardiac patients. Patients who are suffering from hyperthermia when their metabolism is suppressed and their internal temperature is on critical overdrive--increasing their ETCO2 levels significantly. ETCO2 is also used among asthmatic patients and those with anxiety disorders by teaching them how to effectively control their breathing. Furthermore, it has been verified that in postoperative patients especially “high risk”-those with obstructive sleep apnea and those receiving high doses of opioids for pain management are more of an increased risk of adverse respiratory events and through proper patient monitoring through use of ETCO2 can prevents such undesired events. “Capnography can serve as a rapid assessment and triage tool for critically injured patients and victims of chemical exposure. It provides the ABCs in less than 15 seconds.”-Krauss, Heightman, JEMS,
