VI. PRECAUTIONS
•
To assure that operation will be trouble-free, attention should be given to the
following points:
•
ALWAYS TEST THE IC-2A EACH TIME BEFORE ATTACHING TO A PATIENT.
•
All hoses should be securely fastened to fittings. Hand-tighten to avoid damage to
fittings.
•
Gas supplies must be maintained at 50
±
5 psi (345 ±34.5 kPa).
•
Flow restrictions (e.g., flowmeter, check valves, etc.) must not be placed in supply
lines.
•
Gas going to patient should not be super-saturated, as evidenced by excessive rain-
out in the tubing. Condensation droplets on the inner walls of the tubing is normal.
•
Humidifier, when used, must be placed between PATIENT connection on IC-2A
and hose in patient circuit. DO NOT PLACE IN SUPPLY LINE.
•
When setting INSP. TIME and EXP. TIME controls, for optimum repeatability,
always approach setting by turning knob in a counterclockwise direction.
•
Humidifier should have low compliance, and water maintained at a high level to
minimize compliance changes.
•
Expiration Valve must be positioned with diaphragm cap (white section with pilot
hose connection) up. Exhaust port, on bottom, should be unimpeded. (White
adapter section on exhaust port of the exhalation valve may be removed to limit the
amount of noise produced due to resonance. Do not connect any devices such as
spirometer, alarms, monitors, etc. to exhalation valve line).
•
WHEN THE VENTILATOR MUST BE USED UNATTENDED, ALWAYS USE WITH
AN ALARM SYSTEM, SUCH AS THE BIO-MED DEVICES M-10 OR M-1.
PRESSURE ALARMS SHOULD BE T-CONNECTED TO HOSE ATTACHED TO
GAUGE FITTING OF IC-2A.
•
When setting controls, always start with PEEP/CPAP control fully clockwise, and
MAX PRESSURE control fully counterclockwise to avoid setting PEEP/CPAP above
the maximum pressure limit.
•
Never force the needle valve controls. (INSP. TIME, EXP. TIME, PEEP/CPAP and
MAX. PRESSURE). When they are seated (fully clockwise) they must be firm, but
not over-tightened.
•
Should the INSP. TIME, EXP. TIME, or FLOW RATE control knobs come loose for
any reason, do not attempt to re-fasten them. The calibration of these controls
depends on the position of the knob on the shaft. If this occurs, ventilator must be
