Max Firm
1. Activate Max Firm by pressing mode key: ( ). Max Firm LED will light up this mode. The Max Firm is used to rapidly inflate the mattress.
Max Firm Mode will deactivate after 44 minutes, at which point the LED will turn off and the unit will default to its previous setting. In this mode
the entire mattress will be pressurized to 35+/- 5 mm Hg.

The patient comfort pressure ranges from Soft (level 0 = 8±4 mmHg) to Firm (level 9 = 32±4 mmHg). The Comfort
Control LED displays the patient comfort pressure levels from 0 to 9 and provides a guide to the caregiver to set
approximate comfort pressure level depending on the patient weight. If the patient’s weight to height ratio is above average,
increase the pressure setting by approximately 20% or raising the control setting by 1 or 2 above the expected setting for
that weight.

It takes 40-60 minutes for the mattress to inflate fully (inflation time depends on size of mattress).
It is recommended that Max Firm setting be used during patient ingress/egress, patient wound care, patient turning or patient
cleaning.
