PRODUCT DESCRIPTION
The Air
Life
®
nCPAP System Driver provides continuous positive airway pressure (CPAP) for use
in hospitals to treat spontaneously breathing newborns and infants with Respiratory Distress
Syndrome (RDS), or those recovering from RDS under the supervision of qualified personnel
(e.g., respiratory therapist or nurse). The driver operates on medical grade air and oxygen. The
device has an internal battery and can be used for intra-hospital transport, but is not intended for
use in ambulances or aircraft.
The Air
Life
®
nCPAP System Driver incorporates an electronic gas blender using solenoid valves
and servo-controlled flow to maintain a user-set CPAP pressure and FiO
2
. The user interface
displays oxygen concentration, CPAP level, flow rate, trending, power, and alarm conditions. The
device utilizes both audible and visual indicators for alarm conditions, including text on the LCD
display to help the clinician interpret and correct alarm conditions.
The Air
Life
®
nCPAP System Driver utilizes a long-life ultrasonic oxygen sensor and automatically
performs a two-point oxygen sensor calibration each time the instrument is powered on. The
device automatically performs routine Oxygen Sensor Drift Checks/Calibrations during operation
at 20 minutes, 40 minutes, and every 12 hours thereafter after power up.
The device requires both medical air and oxygen in order to pass the Power-On Self Test and
enter Patient Treatment Mode (the main screen). Due to the nature of the electronic pressure
control and gas blending, the device only delivers gas while it is powered on. When turned off, no
gas flow exits the Patient Circuit Connection or Oxygen Sensor Bleed Port.
The Air
Life
®
nCPAP System Driver is part of a larger system that includes an nCPAP generator,
fixation device, and patient interface (prongs and/or masks). This system has been designed and
tested with Approved Accessories (see Table of Contents) and will perform optimally when used
with accessories provided by Cardinal Health, Inc.
CAUTION
Federal (USA) law restricts this device to sale by or on the order of a physician
or licensed practitioner.
