Cautions; Notes - BIO-MED DEVICES IC-2A Service Manual

CAUTIONS

• Hose fittings should be hand-tightened to avoid damage to fittings.
• The gas supply should be clean and dry.
• Never connect a water supply to these fittings.
• Do not attempt to repair the demand valve. Its assembly is highly critical and
must be performed at the factory.

NOTES

• In the SIMV mode, it is essential that the INSPIRATORY EFFORT control be set
so that the patient can trigger the machine at all times.
• The pressurized tanks should be fitted with regulators adjusted to 50 ± 5 psi.
• Any intensive care ventilator circuit may be used with the IC-2A Ventilator
including a configuration using both inspiratory and expiratory hoses.
exhalation valve may be used. It should be noted that the IC-2A is supplied with
a patient circuit (part number 8002A).
maximum PEEP pressure are calibrated using this exhalation valve. If another
valve is used, there may be a difference in the maximum pressure limit and
maximum PEEP pressure attainable, depending on the area ratios of the
exhalation valve used.
• The IC-2A Ventilator does not have an internal oxygen blender.
• During IPPV an assist control breath will cause response of both the CYCLE and
DEMAND indicators. A control cycle will activate only the CYCLE indicator.
• In the SIMV mode, it is unnecessary to add an external constant flow source due
to the triggered demand flow system.
INSPIRATORY EFFORT control be properly adjusted at all times to assure
proper operation.
• The MAX. PRESSURE control must be turned off (fully clockwise) in the CPAP
mode.
• Do not over-tighten the supply fittings with a wrench, as they could be damaged.
• Do not use the logic supply regulator to decrease the logic supply pressure.
Auto-cycling is not to be confused with the regular timed cycling controlled by the
inspiratory and expiratory settings. Auto-cycling can be detected by a very short
or non-existent expiratory time and also by the activation of the DEMAND
indicator at the beginning of an inspiratory cycle without a vacuum being applied
to the patient circuit.
