This bundle includes the PR BiPAP Auto with Bi-Flex and Humidifier.

The PR BiPAP Auto comes standard with carrying case, bag, memory card, manuals and now packaged with Respironics Performance Tubing.

Respironics has removed the "blue light" LED and the new power light is barely visible. No more insomnia from excess system lights; the light can even be turned off within the system settings. The only common part shared with the M series is a brick-style Power Supply. The PR system comes with a separate, external power supply that allows the machine to stay compact.

System One Humidity Control (included)

The PR BiPAP humidifier and water chamber are breakthroughs for managing rain-out and water damage. System One Humidity Control technology analyzes ambient temperature and patient airflow to reach relative humidity at the mask. Choose from 5 levels of relative humidity.

System One is the first humidifier in the industry which accounts for room humidity. Sensors inside and outside the CPAP machine closely monitor changes in humidity and prevents condensation from forming inside the tube.

Dry Box technology is another innovation in reducing water damage to the BiPAP. Several unique designs are incorporated into the humidifier to prevent water from exiting the chamber. To start, the air outlet port has been moved from the side of the humidifier onto the top. This centers the entire delivery; minimizing the total water displacement around the hole. The water chamber is outfitted with a one-way valve, between the machine and the humidifier. Any water that manages to escape the chamber gets trapped within the Dry Box, which acts as a reservoir for any water ingress past the valve.

System One and Dry Box Technology make it possible for the PR BiPAP machines to be truly spill-free. This humidifier, even with a chamber filled to the "Full" indicator line, can be tilted, shaken, and even turned upside down without water leaking back into the device.

System One Resistance Control

Respironics wanted a machine to achieve optimal pressure no matter which mask is used. Resistance Control is the solution, a numbering system on all of Respironics CPAP masks based on variable resistance characteristics. Each number instructs the device to compensate for different mask types. The result? A consistent and reliable pressure enhanced with all the benefits of Flex Technology no matter which mask is used.

Bi-Flex Family Technology

Flex Technology allows the PR BiPAP Auto to track each breath and provide pressure relief during three critical points in the breathing cycle. Pressure is reduced by half centimeter increments during the transition from exhalation to inhalation, inhalation to exhalation and during exhalation.The Bi-Flex setting can be adjusted up to 1.5cm of water pressure for maximum comfort.

Advanced Event Detection and Response

Digital Auto-Trak Sensitivity is the brains behind Respironics' Flex Technology. A patented algorithm monitors breathing patterns and responds to abnormal pressure changes. The Auto-Trak system measures variable triggers and cycle thresholds, adjusted pressure automatically to provide effective sleep therapy.
Advanced event detection and response includes:

• Periodic Breathing
• Clear airway apnea
• Obstructed airway apnea
• Hypopnea
• RERA
• Flow limitation
• Vibratory snore
• Large leak
  
  

The PR BiPAP Auto not only detects these events, the REMstar Auto algorithm responds by automatically adjusting pressure levels to clear the apnea. Within a few seconds of recorded flow reduction, the PR BiPAP Auto pulses a series of pressures to determine if the apnea has been cleared. PR BiPAP Auto responses include:

• Proactive Performance manages events in the early stages of flow limitation, which leads up to an actual obstruction or apnea. The Auto algorithm uses two airflow measurements to prevent pressures from becoming too high: ('P'ressure Critical and 'P' Optimal).
• Leak Management is a comparison of average leak rate and the expected leak from a CPAP mask. Encore records significant losses above the expected leak rate as 'Large Leak' events and the BiPAP Auto reduces therapy pressure to re-establish the mask seal, preventing false apneas.
• Obstructive Apnea is defined as events that reduce 80% of airflow for a minimum of 10 seconds.
• Hypopnea is defined as events that reduce 40% of airflow for a minimum of 10 seconds.
• Flow Limitation is measured through four different baselines of the breathing waveform: Roundness, Flatness, Peak, and Shape. Most other BiPAPs only take into account Flatness and Shape.
• Snore or snoring can sometimes imitate a hypopnea event. Advanced detection allows the PR BiPAP Auto to measure vibrations and partial airway occlusions.
• RERAs differ from a Hypopnea or snoring event in that a RERA shows increasing 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 and central apneas are distinguishable from obstructed apnea or snoring events.
• SmartRamp helps manage apnea events while users attempt to fall asleep. Unlike other BiPAPs, the PR BiPAP Auto can react to an event during Ramp Time.
  
  

Encore Data Management and Reporting

On-board memory has been added to the BiPAP as well as storing information on a generic SD Memory card and reads through any SD card reader. Use Encore Pro 2 Software to monitor therapy effectiveness through a series of reports. A new Patient Flow and Event report enables users to view a weekly breakdown on per-breath basis. Patient data is used to identify particular conditions and events with specific colors.
