z If the input interface of the sampling tube starts showing red blinking, or a
Nomoline clogging message is displayed on the host, the sampling tube should be
replaced.
z It is not allowed to alter this equipment without the manufacturer’s authorization.
If this equipment is altered, appropriate checking and testing must be conducted in
order to make sure that it can be safely operated over a long period of time.
z The ISA gas analyzer is not designed for being used in a MRI environment.
z During MRI scanning, the host equipment must be placed outside the MRI room.
z Using high frequency electrosurgical equipment in the vicinity of the ISA/host
equipment may produce interference, which will result into incorrect
measurements.
z Do not use the external natural heat dissipation function of the ISA equipment.
z Do not apply a negative pressure (such as using a syringe) onto the Nomoline to
remove condensed water.
z If the positive or negative pressure in the patient circuit is too high, it may affect
the sample’s flowing speed.
z If the discharging or sucking pressure is too high, it may affect the sample’s
flowing speed.
z The discharged gas should be discharged into the patient circuit, or into a
discharging system.
z If the collected gas sample needs to supply air for respiration, a germ filter should
be used at the discharging side all the time.
z When placing the ISA gas analyzer, try not to place it at a position where the
analyzer might fall onto the patient's body.
