08-01 Confirmation of ETT Required Capnography
|Subject||Confirmation of ETT Required Capnography|
To establish a standard of treatment and promote the use of adjuncts to confirm proper placement of Endotracheal (ETT) Tube intubation. SEMAC has endorsed and recognized as a standard of care that all out-of-hospital adult and pediatric patients who require ETT intubation must have waveform capnography in place at the time of intubation and throughout the entire time the ETT is in place. This advisory becomes effective state-wide on June 1, 2009.
Endotracheal intubation in adult and pediatric patients with severe respiratory failure or arrest can be a vital intervention for the prehospital advanced life support provider. However, since failure to detect improper placement or dislodgement of an ETT or other advanced airway device can be fatal, utmost care must be take to ensure proper placement. Use of definitive confirmation and continuous monitoring devices are of utmost importance in the prehospital setting and ambulance environment where movement of the patient at the scene and during transport increases the potential for unrecognized dislodgement. Advanced life support providers should use the following confirmation techniques during and after ETT placement to reduce the chance of unrecognized misplacement or dislodgement.
Confirmation Procedures Include:
- ETT use should be confirmed by direct visualization of the ETT passing through the vocal cords.
- Visual inspection of the chest for the presence of symmetrical chest rise.
- Auscultation at the epigastrum for absence of gurgling sounds.
- Auscultation at the anterior and lateral chest walls for the presence of bilateral breath sounds.
- Use of an exhaled carbon dioxide detector device or esophageal detector device.
Definitive Confirmation & Continuous Monitoring
- Continuous End Tidal CO2 waveform capnography monitoring. The capnography device must have the ability to print and/or store the data of the continuous waveform monitoring documentation as well as QA/QI purposes. The ability to print the data should be accomplished at the hospital when ever possible.
Adjuncts for confirmation of proper ETT placement may not be reliable under certain circumstances. As with many devices, there are limitations and special considerations that can affect results and interpretation. Providers must follow the manufacturer's guidelines for proper use and storage of these devices. When used properly these devices may further verify successful intubation and help to eliminate unrecognized esophageal intubation.
The REMAC will develop and implement a process to monitor the success rate for the placement of advanced airway devices by pre-hospital providers. The REMAC shall report the results annually to the SEMAC. This will include at least the following:
- Develop and implement a process to track use of confirmation devices by type in adult and pediatric patients who are intubated.
- Develop and implement a process to record physician verification of proper tube placement on arrival at the emergency department.
- Develop and implement a process to provide continuing education and appropriate remedial training based on the results of 1 and 2 above.
