Introduction
Overview
The Resuscitaire® Birthing Room Warmer (WBR82) is designed especially
for labor and delivery use (see figure 1-4 on page 1-5). It consists of a
detachable cart and bassinet and a freestanding warmer that provides heat
control and monitors skin temperature and includes an Apgar timer. The
Resuscitaire® Birthing Room Warmer also includes an optional resuscitation
package with suction and oxygen delivery or AutoBreath™ Infant Resuscitator
which is a gas-powered, time-cycled, continuous flow, pressure-limited
resuscitator (not available in the U.S.). Other options include a reserve gas
supply and Blender Module.
The Resuscitaire® Radiant Warmer (RW82) is designed for use during labor
and delivery (see figure 1-5 on page 1-6). The Resuscitaire® Radiant Warmer
consists of a bassinet, warmer, and a Controller Module that provides heat
control, monitoring of the skin temperature, and Apgar timing. The Variable
Height Adjustable (VHA) Resuscitaire® Radiant Warmer provides an
adjustable mattress height from 89.9 cm (35.4") to 109.9 cm (43.3"). The
Resuscitaire® Radiant Warmer also includes the same optional resuscitation
package with suction and oxygen delivery or AutoBreath™ Infant Resuscitator
which is a gas-powered, time-cycled, continuous flow, pressure-limited
resuscitator (not available in the U.S.)that are available with the Resuscitaire®
Birthing Room Warmer.
The Resuscitaire® Wall Mounted Radiant Warmer (WMRW82) is designed
specifically for labor, delivery, and birthing room use (see figure 1-6 on page
1-7). The Resuscitaire® Wall Mounted Radiant Warmer consists of a warmer
and a Controller Module that provide heat control, monitoring of the skin
temperature, and an Apgar timer. The Resuscitaire® Wall Mounted Radiant
Warmer is installed permanently and, therefore, is not portable. There are no
resuscitation options available with this product.

permits the warmer to pivot 90° to either side for X-ray procedures. In
addition, when the warmer is pivoted, it can be powered to provide heat.
The warmer head contains the quartz heating element and an examination
light. It is mounted to the top of the upper column. The warmer head pivots to
either side of the warmer to provide access for a portable X-ray machine. There
is no latch required to move the warmer head. An applied force of
approximately 5 kg (10 lb) is all that is required to overcome the detents of the
warmer head pivot.
Heating Element
The radiant heater consists of a 600 W, quartz, tube heater.
Examination Light
An examination light provides added illumination of the mattress area. The
examination light is mounted underneath the warmer head. It is located on the
center line of the warmer head, directly behind the radiant heating element.
The examination light is a 50 W, fixed-focus, halogen bulb, and is turned on or
off by a key on the front of the Controller Module.

Introduction
Chapter 1: Introduction
Controller Module
At power-up, the microprocessor within the Controller Module performs a
series of power-up diagnostic tests to confirm the proper operation of the
system. During this time, all displays and indicators light (except the Power
Fail light) and a tone sounds.
When powered up, the system initializes in Pre-Warm Mode. In Pre-Warm
Mode, the Controller Module starts the heater at 100% power, and maintains
that setting for 3 minutes, reduces to 60% for 12 minutes, and then reduces the
heater power to 30%. While the heater is in the lowest setting, the unit
continues to provide heat without low limit alarms enabled.
When operating the Controller Module in Manual Mode, the operator can
adjust the heater power from 0% to full power in 10% increments. After 10
minutes of operation in Manual Mode, a Check Patient alarm activates. If the
Check Patient alarm is not acknowledged within 5 minutes the heater to turns
off and an alarm activates.
When operating the Controller Module in Baby Mode, the Controller Module
utilizes a baby skin temperature probe connected between the Controller
Module input and the infant’s skin to automatically adjust the heater output of
the Warmer Module maintaining a digitally-displayed preset temperature.
The Apgar Timer displays the elapsed time (up to 59:59). When the timer is
activated, it sounds a tone alerting the operator after 1 minute, 5 minutes, and
10 minutes have elapsed.
When pressed, the Keypad Lock key enables or disables the Up/Down arrows,
Select Mode key, and the >37° key.
A Procedural Silence timer prevents the Baby Temperature alarm from
sounding for 5 minutes during routine procedures.
The >37°C key enables Temperature Override Mode.
Pressing the °C/°F key alternately selects between the two units of temperature
measurement used to display the baby and set temperature.
The operator can also turn on and off the examination light located in the
Warmer Module by using the Examination Light key on the Controller
Module.
