Basic Sedation Capnography Skills by Ron Eslinger, CRNA, APN, MA

 

Objectives

The learner will be able to:

• Define the components of CO2 monitoring

• Discuss Pros and Cons of Capnography

• Review respiratory cycle

• Compare Capnography to Oximetry

• Identify Parts of the Wave Form

 

Capnography

• Can be an integral part of the monitoring done in moderate and procedural sedation.

• Is used to monitor/measure the amount of carbon dioxide in respiratory gases.

• Provides information about the effectiveness of respiration’s and end-tidal carbon dioxide values.

 

Capnography vs Oximetry

• Capnography monitors ventilation, while pulse oximetry monitors oxygenation.

• Capnography thus provides breath-to-breath feedback, and changes in breathing, like apnea, are reflected immediately.

• Changes in pulse oximetry can lag behind breathing changes.

 

Basic Physiology

• Carbon dioxide is produced in the tissues by metabolism and is then diffused into the blood via the venous system (this is basically equal to cardiac output)

• The blood carrying carbon dioxide enters the right side of the heart and from there travels to the lungs.

• This is where oxygen enters the blood.

 

Increased Safety of Nurse Sedation

• Acute respiratory events or respiratory depression were earlier identified due to the monitoring of the waveforms on the capnography monitor

• Capnography can also help detect alveolar hypoventilation even in the presence of supplemental oxygen

• The use of capnography can reduce hypoxemia and lead to better outcomes in patients undergoing moderate sedation.
