Key Features of AVAPS Machines

1. Adaptive Target Volume Support

• Automatic Adjustment: AVAPS (Average Volume Assured Pressure Support) ensures that your set target tidal volume (the amount of air per breath) is delivered. The machine assesses your breathing patterns and automatically adapts the inspiratory pressure to match your needs.
• Consistency: Unlike basic BiPAP machines that provide fixed pressures, AVAPS delivers consistent volumes, even as your lung mechanics or respiratory effort change through the night.

2. Hybrid Therapy Model

• Combination of Comfort and Control: AVAPS machines blend the comfort of non-invasive ventilation with the control of volume-targeted support. This is particularly useful for patients experiencing variable muscle strength or fluctuating respiratory drive.
• Patient-Friendly Transition: These devices allow smoother pressure transitions, reducing discomfort and improving sleep and therapy compliance.

3. Versatile Indications

• Chronic Respiratory Failure: Especially helpful for people with diseases where breathing can progressively decline, such as ALS (amyotrophic lateral sclerosis) or muscular dystrophy.
• Obesity Hypoventilation Syndrome (OHS): AVAPS helps maintain stable breathing and blood gas levels despite challenging lung mechanics caused by excess body weight.
• Other Applications: Also used for severe COPD, central sleep apnea, restrictive thoracic disorders, and select heart failure patients.

4. Advanced Monitoring and Remote Connectivity

• Continuous Monitoring: Most modern AVAPS machines provide real-time feedback on tidal volume, pressure, respiratory rate, and oxygen saturation.
• Data Transfer & Remote Adjustments: High-end models (like those from Philips or ResMed) offer cloud-based connectivity, allowing clinicians to monitor patient data remotely and make adjustments without in-person visits.

5. Safety and Backup Features

• Alarm Systems: Integrated alarms notify users and caregivers if performance falls outside safe limits, such as if the target volume is not achieved or if there’s a mask leak.
• Backup Rate Functionality: Intelligent backup respiratory rate ensures that even if your breathing slows or stops (e.g., during sleep or due to illness), the machine compensates automatically to maintain adequate ventilation.

Using AVAPS Machines: Applications & Safety at Home

How AVAPS Machines Work

AVAPS machines use a non-invasive mask system – either full-face or nasal – connected to a compact ventilator unit. The user breathes through the mask, and the machine automatically monitors each breath, adjusting pressure support as needed to maintain your prescribed tidal volume.

Set-Up and Daily Use

1. Fitting the Mask: The mask should fit snugly to prevent leaks. Different sizes and styles are available for comfort.
2. Device Programming: Your respiratory therapist or doctor will set the target tidal volume, pressure range, respiratory rate, and alarms for safety.
3. Routine Use: Most users wear their AVAPS device overnight or during naps, but some may require extended use depending on their condition.
4. Monitoring: Devices display real-time respiratory parameters, and some store data for later review or transmission to your care team.

Special Safety Considerations

• Use As Prescribed: Only use AVAPS machines with medical supervision, especially when making any changes to settings.
• Cleaning and Maintenance: Clean masks, tubing, and filters regularly to prevent infections. Follow manufacturer instructions.
• Backup Power: For patients who rely on their device around the clock, invest in a battery backup to maintain therapy during power outages.
• Alarms: Never ignore device alarms. If unresolved, contact your provider.
