Frequently Asked Questions

How will it feel when I am breathing with the S8 Escape II?
When you first use your S8 Escape II, you may feel uncomfortable breathing against the airflow. This is normal. You will continue to breathe normally while you sleep. The EPR  setting may also improve comfort. Take time to adjust to this new sensation.
What do I do when I want to get up at night?
If you need to get up during the night, remove your mask and stop therapy.
Always remember to restart therapy and put your mask on when you return to bed.
What do I do if I feel air leaking out of the mask?
The S8 Escape II 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. For example, try repositioning the mask and adjusting the straps.
If you are 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.
If you are using a full face mask and you have problems trying to get a comfortable mask fit, contact your clinician or equipment supplier. You may benefit from a different size or style of mask.
Anything special I should do before putting the mask on?
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.

General Warnings and Cautions

Warnings

• Read the entire guide before using the S8 Escape II.

• Advice contained in this guide should not supersede instructions given by the prescribing physician.

• A patient should not connect a device to the data communication port unless instructed to do so by their health care provider or physician. Only ResMed products are designed to be connected to the data communication port.
  Connecting other devices could result in injury or damage to the S8 Escape II device.

• The S8 Escape II should be used with masks (and connectors)
  recommended by ResMed, or by a physician or respiratory therapist. A mask should not be used unless the S8 Escape II device is turned on and operating properly. The vent hole or holes associated with the mask should never be blocked.
  Explanation: The S8 Escape II is intended to be used with special masks (or connectors) which have vent holes to allow a 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.

• In the event of power failure or machine malfunction, remove the mask.

• The S8 Escape II can be set to deliver pressures up to 20 cm H2O. In the unlikely event of certain fault conditions, pressures up to 30 cm H2O are possible.

• If oxygen is used with this device, the oxygen flow must be turned off when the device is not operating.
  If the oxygen has been left on, turn off the device, then wait 30 minutes before turning on the device again.
  Explanation: When the CPAP device is not in operation and the oxygen flow is left on, oxygen delivered into the air delivery tubing may accumulate within the CPAP  machine enclosure and create a risk of fire. This applies to most types of CPAP machines.

• Oxygen supports combustion. Oxygen should not be used while you are 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.

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

  • Do not use the S8 Escape II if there are obvious external defects or unexplained changes in performance.
  • Do not open the S8 Escape II case. There are no user-serviceable parts inside. Repairs and internal servicing should only be performed by an authorized service agent.
  • Explosion hazard—do not use in the vicinity of flammable anesthetics.

Cautions

• 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.
• The airflow for breathing produced by this device can be as much as 11ºF (6ºC) higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 90ºF (32ºC).
• When AC mains power (100–240V AC) is not available, always use a ResMed DC-12 converter. (The DC-12 converter is available as an optional accessory. It is not  supplied with all models.)
  Note: The above are general warnings and cautions. Specific warnings cautions and notes appear with the relevant instructions in the manual.
