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.

For operating precautions for the Resuscitaire® Radiant Warmer Products and

their accessories, refer to the Resuscitaire® Radiant Warmer Products User

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.

Cart/Bassinet (Resuscitaire® Birthing Room Warmer (WBR82) and

Cart Only)

The bassinet is designed to provide maximum function and utility to aid in the

care of the newborn. It is detachable so you can transport the infant to the

NICU, the general nursery, or another area of the hospital. The side and front

panels fold down to permit access to the infant. The mattress tilts at a 0°, 5°, or

10° angle. Vari-tilt models are continually adjustable to ±10°. Openings are

provided on each side of the bassinet for the insertion of the accessory x-ray

cassette tray. A writing surface is available; when the writing surface is closed,

it is not visible. Each cart has a pass-through drawer and a locking front access

drawer. The cart locks in place when used with a warmer.

Bassinet (Resuscitaire® Radiant Warmer (RW82) Only)

The bassinet is designed to provide maximum function and utility to aid in the

care of the newborn. You may fold the side and front panels down to gain

access to the infant. The mattress tilts at a 0°, 5°, or 10° angle. Vari-tilt models

are continually adjustable to ±10°. Openings are provided on each side of the

bassinet for the insertion of the accessory x-ray cassette tray. A push-through

drawer is supplied standard on every unit.

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.
