What is ASV therapy for sleep apnea?
The relatively recent ASV therapy is more commonly used for people who also experience central sleep apnea. What Are ASV Machines? Adaptive servo-ventilation 6 (ASV) machines monitor a person’s breathing while they sleep and deliver customized air pressure to stabilize breathing 7.
What is Adaptive Servo Ventilation (ASV)?
Created in 1998, Adaptive Servo Ventilation (ASV) is a non-invasive method for treating central sleep apnea and other conditions such as complex sleep apnea, mixed sleep apnea, and Cheyne-Stokes. Adaptive servo ventilation is a relatively new central sleep apnea treatment that continuously monitors the breathing status of patients.
Why would my doctor prescribe an ASV?
Your doctor may prescribe an ASV for you if your CPAP hasn’t worked for your sleep apnea, or if using a CPAP or bilevel positive air pressure (BiPAP) device led to complex sleep apnea. ASV can also help if you have sleep-related breathing disorders from taking opioids for chronic pain.
Should ASV therapy be used in patients with chronic heart failure?
ResMed and regulatory authorities cautioned against the use of ASV therapy in patients with symptomatic chronic heart failure (NYHA 2-4) and reduced LVEF</=45%, AND moderate to severe predominant central sleep apnea. On May 15th, Respironics responded to the update.
What is ASV therapy?
Adaptive Servo Ventilation (ASV) is a non-invasive ventilatory treatment option created specifically for the treatment of adults who have obstructive sleep apnea and central and/or complex sleep apnea.
Is ASV the same as CPAP?
The main difference between ASV and CPAP machines is that ASV machines deliver air pressure dynamically, adjusting according to the person's breathing patterns, whereas CPAP machines deliver a set level of air pressure throughout the night. Each device has specific benefits depending on the type of sleep apnea.
When do we use ASV?
An ASV device is ideally suited for patients who have developed complex sleep apnea when using CPAP or BPAP devices, since it offers the variable flow of pressure, and adjusts as needed throughout the night. This technology accommodates to treat both obstructive and central sleep apnea events.

How does ASV ventilation work?
ASV adapts ventilation breath-by-breath, 24 hours a day, and from intubation to extubation. ASV automatically employs lung-protective strategies to minimize complications from AutoPEEP and volutrauma/barotrauma. It also prevents apnea, tachypnea, dead space ventilation, and excessively large breaths.
Is ASV a ventilator?
The ASV is a ventilatory mode that adapts to patient respiratory effort. Depending on the spontaneous RR, ASV can work as PCV, if there is no spontaneous breathing; as pressure SIMV (P-SIMV), when patient RR is lower than target; or as PSV, if the RR is higher.
Can central sleep apnea be cured?
Treatment-Emergent Central Sleep Apnea: Formerly known as complex sleep apnea, this is a type of central sleep apnea that starts to occur after someone begins continuous positive airway pressure (CPAP) treatment for OSA. In most cases, this version of CSA resolves on its own.

Can sleep apnea come back after surgery?
Uvulopalatopharyngoplasty (UPPP) surgery (which removes tissue from the back of your throat) may reduce sleep apnea and snoring for some people. But apnea episodes and snoring may return over time. You may still need CPAP after surgery.
How many apneas per hour is normal?
That's because it's considered normal for everyone to have up to four apneas an hour. It's also common if your AHIs vary from night to night. For some CPAP users, even higher AHIs are acceptable, depending on the severity of your sleep apnea.
What is the new surgery for sleep apnea?
Uvulopalatopharyngoplasty or UP3 (UPPP) is a procedure designed to open the throat to allow improved breathing in patients with OSA. During this procedure, excess tissue in the throat is removed to widen the airway and allow air to move through the throat more easily.

They can restore your normal breathing pattern, stabilize your breathing, and reduce how many times you wake up during the night. ASV pressure adjusts to your breathing as it changes during sleep. CPAP air pressure is constant.
How to use ASV?
A few tips for using your ASV: Make sure your mask is snug and won’t slip off as you move while you’re asleep. If you breathe through your mouth when you sleep, you may want to use a mask with a chinstrap. Wear your ASV and mask every time you sleep, even when you nap. This will help you get used to it. What to Expect.

ASV can also help if you have sleep-related breathing disorders from taking opioids for chronic pain. ASV Pros and Cons. The advantages of ASVs include: Comfort. Some people find them more comfortable to use than a CPAP.
What is adaptive servo ventilation?
Adaptive-servo ventilation, or ASV, is a device that treats sleep apnea. It’s a newer, non-invasive option to help you breathe in a steady pattern during the night.
Is ASV better for sleep apnea?
Easier to use. Since ASV works better for some types of sleep apnea, you may be more likely to stick with it. Better for certain types: Central sleep apnea. If you have central sleep apnea, an ASV can tell when your breathing pattern changes while you sleep. It gives you air when you need it, so you breathe more easily.
Do ASVs cost more than CPAPs?
ASVs usually cost more than CPAPs. You and your doctor will want to make sure you need the device before you spend money on one. How to Use an ASV. ASVs work in the same way as CPAP machines. When you’re ready to go to sleep, you’ll slip on a face mask that fits securely over your nose, or your nose and mouth.
Is ASV more expensive than CPAP?
ASVs are a more reliable treatment for breathing problems in people with complex sleep apnea than CPAP. ASV units are more expensive than CPAPs. Not everyone needs to use an ASV instead of a CPAP.
What is the best treatment for sleep apnea?
Along with adaptive servo ventilation, there are two other widely used treatments for sleep apnea. CPAP and BiPAP therapy are the most popular therapies that doctors recommend for patients suffering from different forms of sleep apnea.
Is adaptive servo ventilation a last resort?
While a visit to your doctor is the only way to know for sure which treatment is best for you, it has been found that adaptive servo ventilation is usually considered a last resort option for sleep apnea patients. CPAP and BiPAP therapy are well-known treatments for sleep apnea and many people try these methods to start.
When was ASV first used?
ASV first appeared in 1998, used to continuously monitor sleep breathing status. Its chief value is delivering airway pressure based on the user’s breathing patterns. Intricate computer algorithms respond to the user’s apneas the second they happen. 1
Can you use ASV with heart failure?
Certain patients with chronic heart failure (CHF) must avoid using ASV. In 2015, a major research study (SERVE-HF) delivered an urgent field safety notice after it determined a third of people with heart failure faced increased risk for cardiovascular death following ASV usage. 3,4 If you have CHF, you should expect your doctor to explore other, safer options.
What Are ASV Machines?
Adaptive servo-ventilation 6 (ASV) machines monitor a person’s breathing while they sleep and deliver customized air pressure to stabilize breathing 7.
How Do ASV Machines Work?
Like CPAP devices, ASV machines consist of three basic parts: a face mask, the machine, and a flexible hose that connects the mask to the machine. Before falling asleep, the person puts on the mask and turns on the machine. ASV masks may either be fitted over the nose and the mouth, or just the nose 10.
Risks and Side Effects of ASV
While ASV therapy is effective, it is not recommended for everyone. Specifically, people with a certain type of congestive heart failure coupled with moderate to severe central sleep apnea may have a higher risk of mortality when using ASV therapy.
Who Is ASV Best For?
ASV was originally developed for people with Cheyne-Stokes respirations, a condition linked to heart failure that involves hyperventilation followed by lapses in breathing 16. ASV therapy is also used to treat sleep-disordered breathing in people with:
