PATIENT COMFORT CONTROL LEVEL (K) or
•
The system is designed for patients weighing between 35 ~ 1000 lbs. (15 Kg. ~ 455 Kg.). By pressing the Comfort
Control Keys (K) towards the SOFT position (down arrow) reduces the pressure setting, and the FIRM position (up
arrow) increases the pressure. The patient comfort pressure ranges from SOFT 6
±
5 mmHg to FIRM 32
±
5 mmHg.
Depending on the desired patient comfort level, the controller will increase or decrease the speed of the air blower to
provide the appropriate air flow into the mattress to maintain the desired pressure in the mattress.
•
Once the mattress is inflated to its normal size, lay the patient on the mattress and set the Comfort Control Key(s)
(Soft/Firm) to the desired patient comfort level. Wait 2 minutes for the mattress pressure to stabilize and verify the
appropriate pressure required to support the patient by performing a simple “four finger check”. Make sure that the
patient is lying flat on their back in the center of the mattress. Place four fingers between the air cushions directly
underneath the sacral region of the patient’s body. There should be a minimum of 3 to 4 finger width clearance
between the bottom of the patient and the safety foam base, (on an overlay there is no safety foam base). Repeat this
procedure until the desired patient comfort pressure is achieved.
ALTERNATING PRESSURE (AP) (K-4 models only)
•
To set Alternating Pressure (AP mode), press the (M) Mode key to light up the appropriate AP times 5, 10, 15 or 20
minutes. (K-4oem model)
•
To adjust the low pressure zone of the Alternating Pressure therapy, follow the next steps:
•
(Perform in Stand-By mode) Press and hold “Mode” & “Fowler” keys until unit beeps. (Approx. 3 seconds).
•
7- segment will display “0” (0% mmHg of high pressure setting) or “5“ (50% mmHg of high pressure setting)
•
To end routine and accept setting, press “Power” key.
•
Routine will auto time out in 30 seconds if no key is pressed.
•
Turn on control unit and select Alternating Pressure mode.
•
To set Alternating Pressure (AP mode), press the (AP) key, using the (L) “+/-” key select the desired AP time, 1 to 99
minutes. (K-4 Elite model)
•
To adjust the low pressure zone of the Alternating Pressure therapy, follow the next steps:
•
During Alternating Pressure therapy, press the “Mode” key; A/P settings will be displayed on the screen.
•
Use the (L) “+” and “-“ keys to adjust the Low AP percentage value (10% to 75% of high pressure setting)
•
Unit will time out and setting will be set automatically within 15 seconds.
•
In AP mode, alternate air cushions will inflate to the patient comfort pressure while those cushions between the inflated
air cushions will deflate.
