Chapter 1: Introduction

Your health care professional has determined that supplemental oxygen is of beneﬁt to you and has prescribed

an oxygen concentrator set at a speciﬁc ﬂow setting to meet your needs. DO NOT change the ﬂow settings

unless your health care professional tells you to do so. Please read and understand this entire manual before

using the device.

Intended Use

e EverFlo / EverFlo Q Oxygen Concentrator is intended to provide supplemental oxygen to persons

requiring oxygen therapy. e device is not intended to be life supporting or life sustaining.

About Your EverFlo / EverFlo Q

e device produces concentrated oxygen from room air for delivery to a patient requiring low ﬂow oxygen

therapy. e oxygen from the air is concentrated using a molecular sieve and a pressure swing adsorption

process. Your home care provider will show you how to operate the concentrator and will be available to answer

any questions. If you have additional questions or problems, contact your home care provider.

Warnings and Cautions

Warnings

A warning represents the possibility of harm to the operator or patient.

• For proper operation, your concentrator requires unobstructed ventilation. The ventilation ports are located at the rear

base of the device and at the side air inlet filter. Keep the device at least 15 to 30 cm away from walls, furniture, and

especially curtains that could impede adequate airflow to the device. Do not place the concentrator in a small closed

space (such as a closet).

• Do not remove the covers of this device. Servicing must be referred to an authorized and trained Respironics home

care provider.

• In the event of an equipment alarm or if you are experiencing any signs of discomfort consult your home care provider

and/or your health care professional immediately.

• Oxygen generated by this concentrator is supplemental and should not be considered life supporting or life sustaining.

In certain circumstances oxygen therapy can be hazardous; any user should seek medical advice prior to using this

device.

• Where the prescribing health care professional has determined that an interruption in the supply of oxygen, for any

reason, may have serious consequences to the user, an alternate source of oxygen should be available for immediate use.

• Oxygen vigorously accelerates combustion and should be kept away from heat or open flame. Not suitable for use in

the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide.

• Do not smoke, allow others to smoke or have open flames near the concentrator when it is in use.

• Do not use oil or grease on the concentrator or its components as these substances, when combined with oxygen, can

greatly increase the potential for a fire hazard and personal injury.

• Do not use the oxygen concentrator if either the plug or power cord is damaged. Do not use extension cords or

electrical adapters.

• Do not attempt to clean the concentrator while it is plugged into an electrical outlet.

• Device operation above or outside of the voltage, LPM, temperature, humidity and/or altitude values specified may

decrease oxygen concentration levels.

• Your home care provider is responsible for performing appropriate preventive maintenance at the intervals

recommended by the device manufacturer.

Cautions

A caution represents the possibility of damage to the equipment.

• Do not place liquids on or near the device.

• If liquid is spilled on the device, turn the power off and unplug from electrical outlet before attempting to clean up

spill. Call your home care provider if device does not continue to work properly.

Chapter 2: Operating Instructions

Warning: Do not use extension cords or electrical adapters.

1. Select a location that allows the concentrator to draw in room air

without being restricted. Make sure that the device is at least 15 to

30 cm away from walls, furniture, and especially curtains that could

impede adequate airflow to the device. Do not place the device near

any heat source.

2. After reading this entire manual, plug the power cord into an electrical

outlet.

3. Do either Step A or Step B below.

A. If you are not using a humidifier, connect your nasal cannula to the

Oxygen Outlet Port, as shown in the top illustration on the right.

B. If you are using a humidifier, follow the steps below:

1. Open the filter door on the back of the device as shown.

2. Remove the humidifier connector tube from the back of the filter

door and replace the filter door, as shown.
