User Manual
Components of the Siesta Full Face Mask
eating or drinking for three hours before using the mask. This mask is not
recommended if the patient is taking a prescription drug that may cause
vomiting.
• Do not use the mask without the Non-Rebreathing Valve in place.
• Not applicable for silicone-allergy user.
• This mask should not be used on patients who are uncooperative,
obtunded, unresponsive, or unable to remove the mask.
• Follow all precautions when using supplemental oxygen.
• Oxygen flow must be turned off when the flow generator is not operating,
so that unused oxygen does not accumulate within the flow generator
enclosure and create a risk of fire.
• At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen
concentration varies, depending on the pressure settings, patient
breathing pattern, mask, point of application and leak rate.
• The technical specifications of the mask are provided for your clinician to
check if it is compatible with the flow generator. If it is used beyond
technical specifications or used with incompatible devices, the seal and
comfort of the mask may not be effective, optimum therapy may not be
achieved, and leak, or variation in the rate of leak, may affect the function
of the flow generator.
• Stop using the Siesta Full Face Mask and consult your physician or sleep
therapist, if you have ANY adverse reaction to the use of the mask.
• Refer to your flow generator manual for details on settings and
operational information.
Getting the Right Cushion Size
• The following drawing describes the different features of the face and the
length of the face (H) you need to measure.
• The masks are available in three different sizes.
• Choose the appropriate size according to the table below.
Components of the Siesta Full Face Mask
Siesta Full Face Mask
Thank you for choosing 3B Medical’s Siesta Full Face Mask. The mask is
designed to minimize contact with your face, thus ensuring that you feel
comfortable during therapy. This user manual provides you with the
information you need for the correct use of your mask.
The Mask contains no natural rubber latex.
Intended Use
The Siesta Full Face Mask channels airflow non-invasively to the patient from
a positive airway pressure device such as a continuous positive airway
pressure (CPAP) or bi-level system.
The Siesta Full Face Mask is:
• To be used by adult patients (> 66 lb / 30 kg) for whom positive airway
pressure therapy has been prescribed.
• Intended for single-patient reuse.
CAUTION: In the US, Federal law restricts the sale of this device to sale by or
on the order of a physician.
Contraindications
This mask should be used with caution for patients with following conditions:
• Facial deformity.
• Injured facial skin which will contact with the mask during use.
Getting the Right Cushion Size
Fitting the Mask
Use a standard conical connector if pressure readings and / or supplemental
oxygen are required.
Before Using the Mask
WARNINGS
• The vent holes must be kept clear.
• This mask should only be used with CPAP or bilevel devices
recommended by a physician or respiratory therapist.
• Explanation of Warning: CPAP systems are intended to be used with
special masks with connectors which have vent holes to allow continuous
flow of air out of the mask. When the CPAP machine is turned on and
functioning properly, new air from the CPAP machine flushes the exhaled
air out through the attached mask exhalation port. However, when the
CPAP machine is not operating, enough fresh air will not be provided
through the mask, and exhaled air will be rebreathed. Rebreathing of
exhaled air for longer than several minutes can, in some circumstances,
lead to suffocation. This warning applies to most models of CPAP systems.
• At low CPAP pressures, the flow through the exhaled port may be
inadequate to clear all exhaled gas from the tube. Some rebreathing may
occur.
• To minimize the risk of vomiting during sleep, the patient should avoid
Disassembling the Mask
Notes:
1. The elbow assembly cannot be dissembled from the frame assembly.
2. The valve cannot be dissembled, or damage may be incurred and the
re-installation will become more difficult.
