Complex Sleep Apnea can occur when a person's breathing does not improve despite exposure to CPAP therapy. The ResMed VPAP Adapt SV(Adaptive Servo Ventilation) delivers optimal therapy for complicated sleep-disordered breathing cases like Central Sleep Apnea and Cheyne-Stokes respiration.
Manufactured by ResMed.
Adaptive Servo Ventilation (Adapt SV) Algorithm
The VPAP Adapt SV uses an algorithm to assure that each breath is properly ventilated. The algorithm monitors three key factors to ensure synchronization between CPAP pressure support and the patient's breathing.
- The patients own recent average respiration rate
- Changes in patient airflow
- Backup respiratory rate
Complex Sleep Apnea Detection and Response
The VPAP Adapt SV is designed to identify and respond to symptoms beyond classic OSA parameters. Detection is expanded to include data on Periodic Breathing and Respiratory Effort-Related Arousals (RERAs). This device can monitor the breathing cycle and deliver comfortable pressures proactively for patients with complex events such as:
- Restrictive disorders (kyphosis or fibrosis)
- Periodic breathing such as Cheyne-Stokes Respiration (CSR)
- Obstructed airway apnea
- Obesity with hypo-ventilation
- Complex SDB
- COPD and OSA
- Neuro-muscular disorders and SDB
RERAs differ from a hypopnea or snoring event in that a RERA shows increased respiratory effort with each breath, culminating in a shift in brain wave activity and not necessarily a result of obstruction. Periodic breathing conditions such as Cheyne-Stokes respiration (CSR) and Central Apneas are advanced forms of Central Apnea and are identifiably different from Obstructed Apnea or snoring events.
Advanced Back-Up Rate
Complex Sleep Apnea is a form of Central Apnea that occurs as a result of CPAP therapy. In treating such users, care must be taken not to over or under-ventilate while still allowing for natural pauses in breathing. The advanced backup rate for the VPAP Adapt SV accounts for the user's spontaneous breathing. This system will automatically calculate the backup rate based on a natural respiratory rate.
