VAuto Mode

VAuto mode features ResMed's unique Easy-Breathe natural pressure waveform, designed for patients with normal lung mechanics, for maximum comfort. VAuto now also incorporates the Enhanced AutoSet algorithm with central sleep apnoea (CSA) detection.

 

Patient conditions

VAuto mode is useful for OSA patients, who need set pressure support for comfort, with Enhanced AutoSet automatically titrates the upper airway. The inclusion of CSA detection allows clinicians to monitor more difficult patients for central sleep apnoea and prescribe ASV therapy if required.

 

Easy-Breathe waveform

• Provides a comfortable, natural breathing experience The physiologically-based shape of the waveform mimics patient effort during normal breathing. The waveform used in other devices on the market mimics the patient flow shape. The flow shape does not necessarily reflect patient effort and may not be truly indicative of the patient's needs.
• Increases pressure as required throughout the inspiration cycle Peak pressure in each breath is reached for the shortest possible duration, which improves comfort. Patients' actual pressure requirements vary throughout the inspiration cycle. At the beginning of inspiration a lower therapy pressure is required to keep the airway open. The pressure is increased throughout the rest of the inspiratory phase to prevent flow limitation and snoring.
• Supports lung compliance Designed for patients with normal lung function, VAuto reduces the patient's work of breathing with a gentle pressure profile.

 

Enhanced AutoSet algorithm

ResMed's renowned AutoSet algorithm has now been further enhanced. It still benefits from three lines of defence, responding to:

• flow limitation
• snore
• obstructive apnea.

 

In addition, the enhanced AutoSet algorithm now includes:

• central sleep apnea (CSA) detection
• recognition of a wider range of flow limitation shapes
• hypopnoea qualification

 

In VAuto mode, pressures extend up to 25 cm H2O, and pressure support can be set from 0–10 cm H2O. Pressure support remains constant throughout the night, while the AutoSet algorithm adjusts IPAP and EPAP according to the three lines of defence. Constant pressure support can reassure the physician that the patient is receiving the support that they need.
