ResMed Swift LT - NASAL PILLOWS SYSTEM Manual

Intended Use

The Swift LT channels airflow noninvasively to a patient from a positive airway pressure device such as a continuous positive airway pressure (CPAP) or bilevel system.
The Swift LT is:

• to be used by adult patients (> 66 lb/30 kg) for whom positive airway pressure has been prescribed
• intended for single-patient re-use in the home environment and multipatient re-use in the hospital/institutional environment.

Using the Swift LT

When using the Swift LT with ResMed flow generators that have mask setting options, if available select 'SWIFT'; otherwise select 'MIRAGE' as the mask option.
For a full list of compatible devices for this mask, see the Mask/Device Compatibility List on www.resmed.com on the Products page under Service & Support. If you do not have internet access, please contact your ResMed representative
Notes:

• The Swift LT is not compatible for use with ResMed AutoSet CS™ 2 and VPAP™ Adapt SV devices.
• SmartStop may not operate effectively when using Swift LT with some flow generators that have this feature.
• If you experience nasal dryness or irritation, use of a humidifier is recommended.

Swift LT mask components

Fitting your Swift LT

1. (A) Hold the pillows at your nose; (B) pull the headgear over your head.
   
2. Adjust top straps (overtightening may cause excess pressure on your nose).
   
3. Adjust each end of the backstrap (overtightening may cause excess pressure on upper lip).
   
4. Rotate frame to adjust pillow angle to ensure it sits comfortably.
   
5. Connect the short tube to the flow generator's air tubing.
   
6. The Swift LT is now fitted and ready for use. Headgear should sit midway between ear and eye.
   

Using the Plastic Tube Retainer (Optional)

1. Push tube retainer into buckle. Clip either short tube or air tubing to tube retainer.
   
2. When using the tube retainer, the tubing can be positioned to either side of your face or centered.
   
3. If the mask pulls on your nose, increase length of tube between mask and tube retainer.
   

Disassembling your Swift LT

1. Detach air tubing from short tube.
   
2. Remove headgear from frame.
   
3. Remove pillows from frame.
   
4. Remove elbow from frame.
   

Cleaning your Swift LT in the home

Notes:

• The nasal pillows system and headgear should be cleaned by handwashing.
• The headgear may be washed without being disassembled.

Do not use aromatic-based solutions or scented oils (eg, eucalyptus or essential oils), bleach, alcohol or products that smell strongly (eg, citrus) to clean any of the system's components. Residual vapours from these solutions can be inhaled if not rinsed thoroughly. They may also damage the system, causing cracks.

If any visible deterioration of a system component is apparent (cracking, crazing, tears etc.), the component should be discarded and replaced.

Daily/After Each Use
Handwash the separated mask components (excluding headgear) by gently rubbing in warm (approx. 86°F/30°C) water using mild soap for one minute. Rinse all components well with drinking quality water and allow them to air dry out of direct sunlight.

Weekly
Handwash the headgear and tube retainer in warm (approx. 86°F/30°C) water using mild soap. Rinse well and allow them to air dry out of direct sunlight.

Reprocessing your Swift LT between Patients

Only Sleep Lab Mask (SLM) variants of the mask are intended for multi-patient re-use. When using between patients, these masks must be reprocessed according to cleaning and disinfection instructions available on ResMed.com/downloads/masks.

Storage

Ensure that your Swift LT is thoroughly clean and dry before storing it for any length of time. Store the mask in a cool dry place out of direct sunlight.

Reassembling your Swift LT

1. Insert elbow into frame.
   
2. Align pillows with frame.
   
3. Push pillows firmly into frame. Ensure top and bottom retention tabs slot into place.
   
4. Check positioning markers on pillows and headgear are on the same side.
   
5. Slide left and right headgear stability arms onto frame. Ensure inner wall of pillows is in correct position. If not, squeeze pillow sides to release inner walls.
   

Reassembling the headgear

Lay out the headgear as shown, writing facing upwards.

(A) Thread the top straps through the top buckle, then (B) back over to secure.

(A) Thread both backstraps through the back buckle (Velcro™ facing outwards), then (B) fold back over to secure.

Troubleshooting

Before using your Swift LT

• The vent holes must be kept clear.
• The mask should not be used unless the CPAP system is turned on and operating properly.
• 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 that they are compatible with the flow generator. If used outside specification or if 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 flow generator function.
• Discontinue using the Swift LT if you have ANY adverse reaction to the use of the mask, and consult your physician or sleep therapist.
• As with all masks, some rebreathing may occur at low CPAP pressures.
• Refer to your flow generator manual for details on settings and operational information.
• Remove all packaging before using the mask.

Technical specifications

Note: The mask system does not contain latex, PVC or DEHP materials.

Pressure–Flow Curve	Note: The mask contains passive venting that meets the requirements for protection against rebreathing as specified in ISO 17510-2. As a result of manufacturing variations, the vent flow rate may vary.
Dead Space Information	Physical dead space is the empty volume of the mask to the end of the swivel. Using the large cushions this is 94 mL.
