VII. MAINTENANCE
A. NORMAL CARE
The MVP-10 Pediatric Ventilator requires very little maintenance. It should be
protected from abusive mechanical shock and kept in a clean condition.
The MVP-10 should only be cleaned by wiping the outside surfaces with alcohol
applied to a tissue or cloth. It should never be sprayed with or immersed in any
other liquid.
The instrument should be returned to BMD for repair.
The supplied expiration valve is disposable and should be replaced for every
patient, or during extended periods for a single patient. Any possible use of
alternative valves should be discussed with BMD before any patient application.
BMD defers to user facility protocol for recommended time-period of use of
patient breathing circuits (tubing sets).
Care should be taken in connecting supply hoses to the POWER OXYGEN and
AIR fittings. Hand tightening of these fittings is sufficient. Do not over-tighten
with a wrench, as the fittings could be damaged. Never connect a water supply
to these fittings. Use only clean, dry, oil- free medical gas.
B. CHECKOUT PROCEDURE
For the following tests, the unit will require supply connections of 50 ±5 PSI (345
±34.5 kPa) medical grade oxygen and air sources and an infant breathing circuit,
Bio-Med Devices part number 2030, with the patient port occluded (test lung not
recommended).
1. BLENDER/FLOWMETER
CYCLE/CPAP switch to CPAP
PIP full CW
PEEP PRESSURE full CW
Slowly increase flow in each column of flowmeter until indicators reach stops at
tops of columns. Indicator balls should not stick at any point. CLOSE BOTH
FLOW VALVES FINGER TIGHT. Occlude patient circuit exhalation valve
exhaust outlet and verify that manometer indicates a maximum 1 cm increase in
pressure over a two second interval.
2. MANOMETER
Using a variable low pressure source and known standard, verify 3% full scale
accuracy and a zero of ±1 cm.
