You must tell your doctor, and CPAP (continuous positive airway pressure) therapy must not be used, if you have any of the following conditions: pneumothorax or pneumomediastinum (air in the pleural cavity or mediastinum) severe heart failure, low blood pressure, or dehydration surgery to the brain, middle or inner ear, pituitary gland, or sinuses respiratory distress syndrome middle ear infection or perforated ear drum severe nosebleed.

ARNINGS

•

•

•

CPAP therapy should be used with caution if you have any of the following conditions:

•

• respiratory failure cavities or cysts in the lung (called bullae, and usually due to emphysema), or previous history of pneumothorax

•

• previous history of severe nosebleed sinus infection.

Tell your doctor if you have any of these conditions. Your doctor will advise you whether the likely benefits of CPAP therapy outweigh the expected risks.

•

•

•

Special care should be exercised if you are dehydrated, or may become dehydrated, for example as a result of fluid restriction or diuretic therapy (including changes in therapy).

Discontinue therapy and seek medical advice if, during therapy or when you start therapy each night, you feel faint or light-headed.

The following are general warnings that pertain to your use of a

R

ES

M

ED

S7

L

IGHTWEIGHT

unit. Specific warnings appear next to the relevant instructions in the manual.

This is NOT a life support device. It may stop operating with power failure or if a fault occurs in the unit.

The air flow for breathing produced by this device can be as much as 11 o

F (6 o

C) higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 90 o

F (32 o

C).

The R

ES

M

ED

S7 L

IGHTWEIGHT

unit should only be used with masks (and connectors)

*

recommended by ResMed, or by your physician or respiratory therapist. A mask should not be used unless the R

ES

M

ED

S7 L

IGHTWEIGHT unit is turned on and operating properly. The vent hole or holes associated with the mask should never be blocked.

Explanation: The R

ES

M

ED

S7 L

IGHTWEIGHT

unit is intended to be used with special masks (or connectors)

*

which have vent holes to allow continuous flow of air out of the mask. When the device is turned on and functioning properly, new air from the device flushes the exhaled air out through the mask vent holes.

However, when the device is not operating, insufficient fresh air will be provided through the mask, and the exhaled air may be rebreathed. Rebreathing of exhaled air for longer than several minutes can, in some circumstances, lead to suffocation.

This applies to most models of CPAP devices.

The R

ES

M

ED

S7 L

IGHTWEIGHT

unit should only be connected to the components, humidifiers, or accessories specified in this manual. Connection of other items may result in injury, or damage to the R

ES

M

ED

S7 L

IGHTWEIGHT

unit.

At low pressures, the flow through the exhalation ports of your mask may not clear all exhaled gas from the tubing. Some rebreathing may occur.

This device is not intended for use with supplemental oxygen.

* Ports may be incorporated in the mask or in connectors that are near the mask.


•

•

Explosion hazard—do not use in the vicinity of flammable anesthetics.

Blocking the hose while in operation could lead to overheating of the device.

W

ARNINGS RELATED TO OXYGEN USE

!

WARNING

If oxygen is used with this device, the oxygen flow must be turned off when the device is not operating.

Explanation: when the device is not in operation and the oxygen flow is left on, oxygen delivered into the air delivery tubing may accumulate within the device enclosure and create a risk of fire. This applies to most types of CPAP machines.

•

•

Oxygen supports combustion. Oxygen should not be used while smoking or in the presence of an open flame.

Always ensure airflow is being generated by the device before the oxygen supply is turned on.

•

Always turn the oxygen supply off before stopping the airflow from the device.

Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration will vary, depending on where the oxygen is introduced, the pressure settings, patient breathing pattern, mask selection, and leak rate.

W

ARNINGS RELATED TO TREATMENT

!

•

•

•

•

WARNING

If you stop your CPAP treatment, your sleep apnea will return.

Always consult your clinician if you expect to be in a situation where you cannot use your

R

ES

M

ED

S7 L

IGHTWEIGHT

unit.

If you are admitted to a hospital or prescribed any other form of medical treatment, always inform the medical staff that you are being treated with CPAP. It is also important to contact the clinician who is treating you for sleep apnea.

If you experience an infection of the upper respiratory tract, middle ear, or sinuses, contact your clinician before continuing your CPAP treatment. You may be advised to stop treatment until the infection has cleared. If you continue with treatment during an infection, be sure to clean your mask and tubing after every use.

Consult your clinician immediately if you experience any of the following symptoms during your CPAP treatment: headache middle ear or sinus discomfort chest pain dryness of the nose, mouth, or throat feeling bloated due to air swallowing air continually leaking out of the mouth while sleeping recurrence of any sleep apnea symptoms while on CPAP.

Skin irritation may occur from sensitivity to the mask materials or from excessively tight headgear straps. A correctly fitted mask and appropriately adjusted straps will often prevent skin irritation. If problems persist, contact your clinician for advice.

OMPENSATION

Changes in altitude will affect the pressure delivered by the

R

ED

S7 L

IGHTWEIGHT

.

The device has a feature which compensates for these changes in altitude.

As you move or travel with the R

ES

M

ED

S7 L

IGHTWEIGHT

to areas of different altitudes, you will need to adjust the altitude compensation setting in the device. To change the altitude compensation setting, see “Using the Menus” on page 14.

There are three altitude settings to choose from:

Altitude Settings

0–2000 ft

2001–4000 ft

4001–7000 ft

(0–610 m)

(611–1219 m)

(1220–2134 m)

For example, if you are at an altitude of 3107 ft (947 m), your altitude compensation setting would be 2001–4000 ft (611–1219 m), as 3107 ft falls within that range.

Note: If you are above 7000 ft (2134 m), consider consulting your clinician.

If using a nasal mask, try to keep your mouth closed during treatment. Air leaks from your mouth can decrease the effectiveness of your treatment. If mouth leaks are a problem, a full face mask or chin strap may help. Contact your clinician or equipment supplier for further details.

F

ITTING

The flow generator delivers the most effective treatment when the mask is well fitted and comfortable. Treatment can be affected by leaks, so it is important to eliminate any leaks that may arise.

If you have problems trying to get a comfortable mask fit, contact your sleep clinic or equipment supplier. You may benefit from a different size or style of mask.

Before wearing your mask, wash your face to remove excess facial oils. This will allow a better fit and prolong the life of the mask cushion.

a

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ResMed S7 Lightweight is used exceeds the applicable RF compliance level above, the ResMed S7 Lightweight should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the ResMed S7 Lightweight.
