Etco2 (Co2) Sensor And Airway Adapter Maintenance (Prism Only); End Tidal Carbon Dioxide (Etco2) (Prism Se Only) - Escort Prism 20401 Reference Manual

ETCO2 (CO2) Sensor and Airway Adapter Maintenance (Prism Only)

CO2 sensor is a precision instrument, which requires proper maintenance to verify accuracy and
durability. Great care must be exercised in handling the CO2 sensor. There are no user serviceable
parts inside sensor. The following precautions will help protect sensor and patients:
•
Do not autoclave airway adapter or sensor
•
Do not immerse sensor or cable in liquid
•
Avoid damaging mainstream adapter glass window
•
Connect mainstream adapter to sensor away from patient
•
Mainstream airway adapter is non-sterile and intended for single patient use only
•
Always use mainstream neonatal adapter (MDE part #E2900-21) for neonatal patients.
•
After use, clean sensor with cloth moistened with green soap/green soap tincture
(V34 or equivalent)
•
Always replace sensor and cable in its protective foam-lined case when not in use

End Tidal Carbon Dioxide (ETCO2) (Prism SE Only)

End tidal carbon dioxide (ETCO2) monitoring can show early indications of circulatory and
pulmonary problems. In order to have a "normal" ETCO2 (CO2) reading a patient must have
active cellular metabolism that produces CO2, a functional cardiovascular system to transport
CO2 to the lungs and a normal intrinsic pulmonary function or proper ventilator-assist function.
Prism SE uses molecular comparison spectroscopy to measure CO2. Prism SE's sensor directs a
single laser beam specific to CO2 through a sampling chamber containing patient exhaled CO2.
The monitor calculates patient's CO2 concentration for each exhaled breath.
Both intubated and nonintubated techniques continuously measure level of CO2 during
inspiration and expiration, and detect changes of CO2 levels during respiratory cycle. These
changes are shown on CO2 capnogram waveform, with numeric values reflecting highest level of
CO2 detected at end of expiration. Additionally, Prism SE senses and displays respiration rate (if
CO2 is selected as respiration source), and measures inspired CO2 (ICO2) to compare to an
adjustable ICO2 alarm limit.

2. Press the ALM ON/OFF softkey to set patient alarms.
3. Press the ALM LIM softkey to adjust alarm values.
4. Press the SCALE softkey to chose appropriate scale.
5. Press the CO2 OFF to turn off ETCO2 function. Turn ETCO2 off after conclusion of
monitoring to prevent technical messages on screen.
6. Press the MORE softkey to view and select the UNIT softkey (% or mmHg), O2 ON/OFF
