The Novametrix
capnograph and pulse oximeter monitor designed for use in a variety of clinical settings. It provides
reliable measurement, display and alerts for, end tidal carbon dioxide (ETCO

monitoring of non-intubated patients.
Numerical and waveform information is presented on a bright Cold Cathode Display (CCD) with user
adjustable contrast to optimize viewing angles. A simple menu system allows user selection of
measurement and display options. Alerts are menu programmable or automatic. Presence of a pulse is
indicated audibly by a user-selectable "beep".
Separate 24 hour trends for ETCO
Trend "events" and audible alarm status (Audio Off) are also stored in trend memory.

leg of the sensor. Carbon dioxide, flowing in the airway adapter as a result of respiration, absorbs some
of this light energy. The monitor relates the amount of detected energy to the amount of CO

operator having to change monitor settings.
Respiration is calculated by measuring the time interval between detected peaks of the CO
The inverse of this measurement is displayed as respiratory rate. Certain rebreathing circuits, or the
presence of artifact such as cardiogenic oscillations, may cause
fluctuations as if they were breaths—this condition affects only the numerical displays, the Capnogram
display continues to provide an accurate picture of the CO

and those introduced by artifact. As a result, when the editor is in use, the monitor will adapt slowly to
sudden changes in respiratory rate.
