Introduction
Introduction
About RespSense II
RespSense II allows healthcare professionals to non-invasively monitor capnometry on either
intubated or spontaneously breathing patients.
When measuring EtCO2, the patient is attached to the monitor by a sample line that can be an
airway adapter for an endotracheal tube, a nasal cannula, or a nasal cannula with supplemental
oxygen delivery. A variety of sample lines can be used and connected to a specially designed
moisture trap, which is easily snapped into the monitor. The sample lines can be used with or
without Nafion®tubing. Use only those accessories recommended by Nonin. Refer to the
Accessories section for more information.
The monitor has a touch screen display where settings and adjustments are made. The only
buttons on the monitor, On/Standby (off) and Audio Pause, are located on the upper right corner
of the front panel. Next to these buttons there is a small indicator that turns green when the monitor
is connected to a power outlet. The monitor operates on a fully-charged battery for approximately
5 hours.
About Capnometry
The monitor uses sidestream non-dispersive infrared (NDIR) spectroscopy to continuously
measure the amount of CO2present at the end of exhalation (EtCO2), and respiratory rate (RR).
Capnometry has been proven to be a reliable method for detecting esophageal intubation,
hypoventilation, and disengagement of the endotracheal tube during mechanical ventilation.
Operator Requirements
Each operator should read this manual before using the monitor. RespSense II should only be
operated by licensed practitioners.
CAUTION: When using sample lines that also deliver oxygen to the patient, it is
important to be aware that the EtCO2value may be diluted when used in
combination with supplemental oxygen. To obtain a true EtCO2reading, it is
recommended that the supplemental oxygen be disconnected for a few seconds to
establish a baseline.
