The ZOLL R Series® uses a small, lightweight plug-and-play Respironics® CAPNOSTAT® 5 sensor, which provides fast response and reliable monitoring.
What Is Capnography?
Capnography is the measurement and numerical display of end-tidal carbon dioxide (also known as EtCO2).
EtCO2 is the maximum expired carbon dioxide concentration during a respiratory cycle.
The graphical representation of the concentration or partial pressure of expired carbon dioxide during a respiratory cycle is shown in a waveform format and is known as a capnogram.

This provides information not only regarding pulmonary function, but also indirect cardiac function, ventilator function, and perfusion.

Why Use Capnography?
In the American Heart Association (AHA) 2010 Guidelines continuous waveform capnography is a Class I, LOE A recommendation for confirming and monitoring correct placement of an endotracheal tube.
Because a sustained increase in PETCO2 during CPR is an indicator of ROSC, the AHA Guidelines also recommend using capnography in intubated patients to monitor CPR quality, optimize chest compressions, and detect ROSC during chest compressions or when the rhythm check reveals an organized rhythm (Class IIb, LOE C).
What Is Mainstream Capnography?
Mainstream capnography is most commonly used for mechanically ventilated patients and intubated patients who require intensive monitoring. Mainstream devices can also used on non-intubated patients but require a mouthpiece or a mask.
With mainstream capnography, the airway adapter is placed directly in the breathing circuit in between the ventilator “Y” and the elbow adapter, as shown in the diagram.
A mainstream sensor is then attached to the adapter. As the patient exhales, the CO2-rich gas passes through the airway adapter, where it is measured. Because the mainstream sensor is not in direct contact with the patient, it cannot be contaminated by moisture or secretions. If the mainstream airway adapter becomes contaminated with secretions, water, or by an aerosolized medication, it can be removed and replaced. The actual mainstream sensor does not need to be replaced.
