System Operation - Invacare MicroAIR 3500S Owner's Operator And Maintenance Manual

System Operation

After placing the patient, make certain no objects will fall under the patient, such as
feeding tubes, IV's etc.
Use a regular pillow to help support and stabilize the patient's head. Make sure the
patient's limbs assume natural positions without pinching. Use pillows, foam or
sheepskin appliances as required to cushion potential body to body contact areas.
When elevating the head of the bed, elevate the knee section first. The therapy pad
is slippery to minimize skin friction. Head elevation without knee elevation may
cause the patient to slide toward the foot of the bed.
DO NOT leave a patient unattended while in AUTO FIRM mode. Otherwise, the
patient might roll off the mattress and injury may occur.
The head of the bed should be maintained at the lowest degree of elevation consis-
tent with medical conditions (AHCPR Pub. 92-0047, P.24). The lowest skin pressure
is maintained with 0° to 20° head raise angle. Angles above 30° place more body
weight over the seat area, reducing pressure relief. Instruct the care-giver to avoid
head angles over 30° for extended periods, unless medically necessary (US Depart-
ment of Health and Human Services publication No. 92-0048).
1. Press the Power button to start the power unit.
NOTE: The mattress will start to fill slowly.
2. Press the Auto Firm button to inflate the mattress to maximum pressure for patient
transfer.
NOTE: A timer will cancel AUTO FIRM in 30 minutes.
3. Check patient weight.
4. Do one of the following:
• If patient weight is between 0-180 lbs, set the Range switch (inside the filter door)
to LOW range.
• If patient weight is between 150 - 350 lbs, set the Range switch to HIGH range (the
blower runs faster when you switch the toggle to HIGH).
5. Adjust Pressure Control Knob fully clockwise.
6. Push the Therapy button to turn Off AUTO FIRM.
7. Position the patient onto the mattress. Refer to Positioning the Patient on the Mattress
on page 18.
NOTE: The foot air sack section will inflate slowly.
NOTE: If the mattress does not inflate, refer to the Troubleshooting on page 24.
