Urgent recall : Resmed ASV machines could increase mortality risk in heart failure

By In heart, treatment On May 15, 2015


Central Sleep Apnoea (CSA) in the setting of Heart Failure usually presents as Cheyne Stokes Respiration (CSR) on a sleep study. One of the ways to attempt to correct CSR is with a particular kind of PAP machine called “ASV”… Auto Servo Ventilation.

ASV machines map your breathing, and apply particular pressures on a breath-to-breath basis.

Today, Resmed released an Urgent Recall of their ASV machines because of an apparent safety concern.

Preliminary analysis of their data suggests an exceedingly high risk of cardiovascular death (33.5% higher) in those with Heart Failure using ASV, compared to those not on ASV.

At Adelaide Sleep, we keep abreast of all new Sleep Developments. All of our patients are consulted before and after their sleep studies, and before and after their treatment commencement, as per the current recommendations by the Australasian Sleep Association (ASA). We do not believe in direct-CPAP-outlet sales, nor do we believe in direct-to-consumer-sleep-study services. By seeing a Medical Specialist, you would’ve had a face-to-face medical consultation regarding your ASV machine.

If you believe that you are on an ASV machine, and would like to speak to a Medical Specialist regarding this, contact us now.

Addit : Philips Respironics have also released a statement echoing that of Resmed – caution in prescribing and using their BiPAP autoSV / BiPAP autoSV Advanced therapy machines and algorithm, in the at-risk group.
