Chapter 1: Warnings, Cautions,

and Notes

WARNING: Indicates the possibility of injury to the patient,

operator, or technician.

CAUTION: Indicates the possibility of damage to the device.

NOTE: Places emphasis on an operating characteristic.

1.1 WARNINGS

1.1.1 Safety

• This device is intended for adult use only.

• This device is not intended for life support or life

sustaining applications.

• The instructions in this manual are not intended to

supersede established medical protocols.

1.1.2 Operational

• This warning applies to most Continuous Positive

Airway Pressure (CPAP) devices. At low CPAP

pressures, the air flow through the exhalation port

may not be enough to clear all of the exhaled gas

(CO2) from the mask. You may breathe in some of

the air that you have exhaled.

• If oxygen is used with this device, the oxygen flow

must be turned off when the device is turned off. If

the device’s air flow is turned off and the oxygen

flow is left on, oxygen may accumulate in the

Tranquility Quest Plus CPAP System enclosure and

may create a risk of fire. This warning applies to

most types of CPAP devices.

• When supplemental oxygen is used at a fixed flow

rate, inhaled oxygen concentrations will vary

depending on pressure settings, patient breathing

patterns, mask selection, and leak rate.

• Oxygen supports combustion. Do not use oxygen

in the presence of open flames, cigarette smoke,

electrical spark, or other sources of ignition.

• This device is not suitable for use in the presence of

a flammable anesthetic mixture with air or with

oxygen or nitrous oxide.

Chapter 1: Warnings, Cautions, and Notes

Tranquility Quest Plus CPAP System Service Manual 2

1003740

• In situations where risk of contamination between

the user and the device is high (e.g.: sleep lab

devices; rental devices; users with respiratory

infections), a low-resistance, main flow bacteria

filter should be placed in-line between this device

and the circuit.

• Most CPAP devices have the potential to induce

rebreathing of exhaled air. To reduce this potential,

use only Respironics circuit accessories, do not

wear the mask and headgear for more than a few

minutes while the unit is not operating, and do not

block or try to seal the vent holes in the exhalation

port.

1.1.3 Service

• Electronic components used in this device are

subject to damage from static electricity. Repairs

made to this device must be performed only in an

antistatic, Electro-Static Discharge (ESD) protected

environment.

• To assure the safety of the service technician and

the specified performance of the device,

Respironics recommends that only technicians

having prior training or experience servicing

ventilatory devices perform any repairs or adjust-

ments to the Tranquility Quest Plus.

• High voltages are present inside this device. To

avoid electrical shock, disconnect the electrical

supply before attempting any repairs on the device.

1.1.4 Cleaning

• To avoid electrical shock, disconnect the electrical

supply before cleaning the Tranquility Quest Plus.

DO NOT immerse this device into any fluids.

1.2 CAUTIONS

• Federal law (U.S.) restricts this device to sale by, or

on the order of, a physician.

• Care should be taken to avoid exposure of the

Tranquility Quest Plus to temperatures at or near

the extremes of those specified in Chapter 2. If

exposure to such temperatures has occurred, the

device should be allowed to return to room tem-

perature before being turned on.

• Always use an intake filter when the Tranquility

Quest Plus is in use.

• Never place liquids on or near the Tranquility

Quest Plus.

• Discontinue using this device if any of the parts are

damaged. Replace any damaged parts before

continuing use.

• The information in this manual is provided for

service personnel reference and is not intended for

system setup or use. System setup should be

performed by appropriate personnel using Home

Care Dealer Instructions.

Chapter 3: Theory of Operation

Tranquility Quest Plus CPAP System Service Manual 5

1003740

The ramp feature lets the user reduce the pressure from the unit so

that the patient can fall asleep at a lower, more comfortable pressure

at any time or as many times as needed during the night.

The patient circuit is made up of the flexible tubing, exhalation port,

and nasal mask. The unit applies CPAP to the patient’s upper

airway to keep the airway open during the sleep. Air flow gener-

ated from the unit is directed to the patient via a mask and flexible

tubing that connects to the air outlet port of the unit.

The Tranquility Quest Plus is intended to deliver CPAP therapy

only. It is not intended for life support or life sustaining applica-

tions.

Chapter 3: Theory of Operation

3.1 Functional Description

The Tranquility Quest Plus is a microprocessor-controlled Continu-

ous Positive Airway Pressure (CPAP) device that produces positive

pressure. The unit operates only in the CPAP Mode. CPAP Mode

pressure range: 3.0 – 20.0 cm H2O.

Integral to the generation of air flow is the blower assembly. Ambi-

ent air is drawn through the air intake filter by the energized blower

and is then pressurized. Ultimately, therapeutic pressure is pro-

vided to the patient via the patient circuit. The microprocessor

regulates the motor speed, which in turn adjusts and controls the

pressure.

The Tranquility Quest Plus’s control pad, which includes three push

buttons and an LCD display is the primary means by which the

patient therapy is controlled. Patients have limited access to unit

parameters.

The unit may be powered from AC voltage (100-240 VAC). AC

power enters the unit via an AC inlet and appropriate power cord.

The two system filters, the pollen and the ultra-fine, ensure opti-

mum operation for the user. An air outlet port allows for connec-

tion to the patient circuit.
