damaged or broken. Observe airway adapter color coding for patient population.
5
Periodically check the flow sensor and tubing for excessive moisture or secretion
buildup.
6
Always connect the airway adapter to the sensor before inserting the airway adapter
into the breathing circuit. In reverse, always remove the airway adapter from the
breathing circuit before removing the sensor.
7
To avoid dead space, place the sensor as close to the patient as possible.
For Masimo Mainstream Module:
WARNING
1
The connection circuit in the host device shall be separated from live parts with
double or reinforced insulation.
2
The host power supply shall employ current limiting, whereby current is reduced or
cut-off under overload conditions.
3
The host equipment shall be equipped with appropriate alarm system to alert the user
of situations which could lead to death or severe deterioration of the patient’s state of
health.
4
Alarm message corresponding to each bit in the status summary field must be
implemented in the host equipment.
5
Incorrect probe zeroing will result in false gas readings.
6
Measurements can be affected by mobile and portable RF communications
equipment. It should be assured that the probe is used in the electromagnetic
environment specified in this manual.

The
concentration of compensated gas should be set based on the current gas concentration which is
supplied for patient. As for O

and N

O, make the supplied gas concentration multiply to its
volume to get the concentration. For instance, supply 100% O

compensation is: 100%*60%=60%. AG concentration is decided by anaesthesia apparatus.
