Mechanical Specifications - Nellcor EasyCap II Manual

CAUTIONS:
1. Inspect the Easy Cap II detector before attaching it to the
endotracheal tube. Do not use if any physical damage is observed.
2. Do not use device in the presence of trichlorethylene or chloroform
anesthetic; chemical interactions will affect device accuracy.
3. Do not subject device to extreme humidity, such as a heated
humidifier or nebulizer; excessive humidity will affect device
accuracy.
4. Reflux of gastric contents, mucus, edema fluid, or intratracheal
epinephrine into the Easy Cap II detector can yield persistent
patchy yellow or white discoloration which does not vary with the
respiratory cycle. Contamination of this type may also increase
airway resistance and affect ventilation. Discard device if this
occurs.
5. In cardiac arrest, re-establishment of cardiac output and
pulmonary blood flow by adequate CPR is necessary to increase
end-tidal CO to levels detectable by the Easy Cap II detector
2
(above 0.5%).
6. The Easy Cap II detector is not a substitute for observation of the
patient. This device must not be relied upon as the sole indicator
of resuscitation performance.
