BED RAIL ENTRAPMENT RISK NOTIFICATION
NOTICE TO PATIENT, PATIENT’S FAMILY AND/OR PRIMARY DAY-TO-DAY CAREGIVER
DO NOT use this product without first completely reading and understanding this Bed Rail Entrapment Risk Notification
and any additional instructional material such as owner’s manual, instruction sheets and on-product warnings supplied with
this product. If you are unable to fully understand this Bed Rail Entrapment Risk Notification, the on-product warnings or
any additional instructional materials, contact the patient’s health care provider and/or your equipment provider before
using this equipment. Failure to understand and comply with the information contained in this Bed Rail Entrapment Risk
Notification can result in serious injury or death.
Entrapment within the bed rail Entrapment under the bed rail Entrapment between the Entrapment between the
bed rail and mattress head or foot board and the
end of the mattress
Entrapment under the bed rail at the ends Entrapment between split bed rails Entrapment between the end of
of the bed rail the rail and the side edge of the
headboard or foot board
RISK OF ENTRAPMENT
Bed Rail Entrapment is a known risk in the use of bed’s equipped with bed rails.
Every patient is unique. Only the patient’s medical care provider is familiar with the patient’s unique medical condition and
needs. Only the patient’s medical care provider and/or the dealer from whom you obtained this equipment, upon proper
assessment of the patient’s medical condition and needs, can evaluate whether this equipment is appropriate for use by any
particular patient and assist the patient, the patient’s family and/or the patient’s primary day-to-day caregiver in assessing
the Risk of Entrapment.
Proper patient assessment, equipment selection, frequent patient monitoring, and compliance with instructions, warnings
and this Bed Rail Entrapment Risk Notification is essential to reduce the risk of entrapment.
Accessories have been developed in the industry to reduce the openings in existing bed systems that could cause
entrapment. Any modification through the use of accessories must be used in conjunction with proper patient assessment
prior to intervention. For a full discussion on this topic, see the Hospital Bed Safety Workgroup’s “A Guide for Modifying
Bed Systems and Using Accessories to Reduce Risk of Entrapment” found at http://www.fda.gov
.
Conditions such as restlessness, mental deterioration and dementia or seizure disorders (uncontrolled body movement),
sleeping problems, and incontinence can significantly impact a patient’s risk of entrapment, Pediatric patients or patients
with small body size may also have an increased risk of entrapment.

K-3 & K-4 Series Owner’s Manual
Page 10
BED RAIL ENTRAPMENT RISK NOTIFICATION
•Bed rails are intended to prevent an individual from inadvertently rolling out of bed, provide assistance to a patient when
repositioning and to provide a sense of security. NEVER use bed rails for restraint purposes where “restraint” means
preventing or hindering the patient within the bed from exiting the bed as they wish. Use of rails as a means of restraint
significantly increases a patient’s risk of entrapment.
•Bed rails are intended to be used as a pair in a bed system. When in use, both side rails must be in the up position,
except when the patient is entering or exiting the bed. Use with one side rail up and one side rail down could create an
increased risk of entrapment.
•Bed rails and/or their mountings should not be used if they are bent or otherwise deformed. Bent or deformed bed rails
and/or bed rail mountings increase gaps and increase the risk of entrapment. DO NOT place pressure upon bed rails
while moving the bed. Although bed rails are not rated to any specific patient weight limitation, the bed rails or their
mountings may become deformed or broken if excessive side pressure is exerted on the bed rails.
•Mattress overlays or active therapeutic support surfaces (TSS), which support the patient on an air mattress or
specialized foam layer, may present an increased risk of entrapment for some patients. The benefit of TSS product use
must be weighed against the potential increased risk of entrapment. The risk judgment must be performed by a medical
professional.
The U.S. Food and Drug Administration in partnership with the U.S. Department of Veterans Affairs, Health Canada’s
Medical Devices Bureau and representatives from national health care organizations and provider groups, patient advocacy
groups, and medical bed and equipment manufacturers including the Hospital Bed Safety Workgroup, a collection of experts
from the United States FDA, health care professionals and manufacturers of hospital beds, published guidelines regarding
body part dimensions as they relate to a bed system’s safety. These guidelines, “Hospital Bed System Dimension and
Assessment Guidance to Reduce Entrapment” contain additional information on the risk of entrapment. Visit the FDA
website at http://www.fda.gov and search for “bed rail entrapment” to learn about the risk of entrapment or to view the FDA
guidelines document.
The above statements are not intended to be a complete or comprehensive list of all risks of entrapment. KAP Medical
recommends that whenever bed products are used that the patient, the patient’s family and/or the patient’s primary day-to-
day caregiver discuss entrapment risks with the patient’s medical care provider.

Plug the other end of the power cord into the control unit and press it in place.
Note: Care should be taken such that the power cord of the control unit is not pinched, or has any objects placed
on it. Ensure it is not located where it can be stepped on or tripped over. Make sure the control units power inlet
connection is positioned to easily disconnect the power cord from the unit.
•Connect the mating connector (R) on the mattress hose assembly (V) into the insert on the control unit connector
and lock it in place.
Note: ELITE Series-Make sure the magnetic connector has a good connection. Also, care should be taken such
that the mattress hose is freely suspended without being pinched or kinked.

•Make sure the CPR, bolsters and air pad plugs are connected and locked in place before inflating the mattress.
•Make sure the left and the right side safety air bolsters (if available) as well as the bottom safety air pad are fully inflated
and up to the correct operating pressure and firm prior to placing a patient on the mattress.
•Make sure the heel regulator valves/knobs in the Universal Mattress (UM) and Expandable Mattress (XM) are in proper
position
OPERATING INSTRUCTIONS
Note: Not all functions are available on all models. {Display labels – page 12 & Figure 1- Page 15}
INITIAL POWER UP
•(K-3 ELITE, K-4 ELITE) During initial power up when power cord (Q) is plugged into the power source (X), the control
unit will display “KAP MEDICAL, LOW AIR LOSS SYSTEM” on K-3 system and “KAP MEDICAL, ALTERNATING LOW
AIR LOSS SYSTEM” on K-4 system for a brief moment and then goes through a system initialization routine for a few
seconds. Once the routine is completed the display (D) will read “KAP MEDICAL STAND BY”.
•(K-3oem, K-4oem) During initial power up when power cord (Q) is plugged into the power source (X), the control unit will
display illuminated amber light indicating that the unit is in Standby mode.
POWER (SB)
•Press Power key, the (amber) Standby LED will turn off and the (green) LED turns on. The blower will turn on.
LOW AIR LOSS
•Continuous Low Air Loss relief is provided at all times when the K-3 or K-4 series system is powered on.
MAX INFLATE (W)
•Press MAX Inflate (W) key, the (green) LED will turn on. This mode is used to rapidly inflate the mattress. During this
mode a series of beeps will sound every 3 minutes as a reminder that MAX Inflate mode has been activated. During this
mode, the entire mattress will be pressurized to 35 ±5 mmHg. The mattress (B) will inflate to its normal size within 60
seconds. MAX Inflate mode will deactivate after 15 minutes.
THERAPY (STATIC) (T)
•To set Static mode press (S) Select key (K-3oem model only) or (M) Mode key until the Static mode
indicator light illuminates and the screen displays THERAPY. The unit will go into “THERAPY” mode.
•In THERAPY mode all the air cushions in the mattress will be maintained at the same pressure and can be adjusted to
the desired patient comfort control level.

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

•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.
