Behind the ASV Machine

For those patients living with breathing disorders where the brain cannot fully regulate breathing patterns anymore – such as central sleep apnea – a regular CPAP machine just cannot handle the necessary breathing regiment. An ASV (adaptive servo-ventilation machine) is required to assist these patients in breathing for both inhalation and exhalation cycles.

There is More that Meets the Eye.

An ASV machine can look nearly identical to a CPAP or BiPAP. See the examples below:

So how can you distinguish which one’s which?

The features within the machine are the significant factors to pay close attention to.

An ASV machine allows patients with central breathing disorders ([tooltip title=”abnormal breathing that can gradually get deeper or quicker to result in an apnea event”]Cheyne-Stokes respiration[/tooltip], [tooltip title=”your brain doesn’t send the right signals to tell the body to breathe regularly”]central sleep apnea[/tooltip], and associated obstructive events or mixed sleep apnea) a chance to have a machine to stabilize breathing with auto-adjusting pressure support and auto-adjusting expiratory positive airway pressure. For ResMed’s AirCurve 10 ASV, this ASV actually targets a patient’s recent minute ventilations in order to provide the most comfortable range of breathing cycle pressures for each patient.

Basically, all ASV machines are the supporting backbone to respiratory wellness for patients who cannot breathe flawlessly of their own accord. By allowing air to keep flowing into a patient’s airway through tested algorithms that match and adapt to each patient’s breathing patterns, an ASV machine can help keep you breathing regularly. It knows what a regular breathing pattern for each patient looks like, so if a patient happens to be breathing a little too infrequently or too shallow, the ASV can help make the breathing pattern regular again.

See the features of the ResMed AirCurve 10 ASV here to get official names for all the complex features of the ASV machine pictured above.

The main concern for those wondering if they should have an ASV machine or not should be:

Can they still breathe regularly during sleep or not?  If their brain isn’t sending signals to keep breathing normally and they tend to stop breathing during the night, it might be necessary to get checked again through a sleep study to see if the patient needs an ASV machine. CPAP and BiPAP machines will not help someone with a central or mixed sleep apnea – only ASV machines can effectively help.
