central sleep apnea

Sleep apnea is a disorder where breathing is repeatedly interrupted while asleep. Sleep apnea is classified as either obstructive sleep apnea (OSA) or central sleep apnea (CSA).

Central sleep apnea is a form of sleep apnea that is less common and less studied than obstructive sleep apnea. Whereas obstructive sleep apnea results from a blockage of the upper airway, central sleep apnea occurs when the brain fails to send appropriate signals to the breathing muscles to stimulate a regular breathing pattern.1

Symptoms of central sleep apnea

CENTRAL SLEEP APNEA HAS SYMPTOMS THAT ARE BOTH LONG TERM AND SHORT TERM. SYMPTOMS OF CENTRAL SLEEP APNEA (CSA) INCLUDE:2-3

CENTRAL SLEEP APNEA HAS SYMPTOMS THAT ARE BOTH LONG TERM AND SHORT TERM. SYMPTOMS OF CENTRAL SLEEP APNEA (CSA) INCLUDE:2-3

slouch
Chronic fatigue
sleep at desk
Excessive daytime sleepiness
brain
Brain fog / cognitive impairment
Inability to fall asleep or get restful sleep

Many patients with CSA also have heart disease, especially heart failure.4 Within this population, patients with CSA are at increased risk for hospitalizations and even death.5,6

CENTRAL SLEEP APNEA HAS A NUMBER OF KNOWN ASSOCIATIONS:2

  • Cardiac disorders including Congestive Heart Failure (CHF) and Atrial Fibrillation (AFib)
  • High altitude
  • Opioids
  • Idiopathic central sleep apnea
  • Other medical conditions (stroke, brainstem/spinal cord disorders)

diagnosing csa

CSA is diagnosed via a home or in-lab sleep study, ethat is prescribed by a physician to determine if a patient has sleep apnea and if their primary type of apnea is central or obstructive.

Home Sleep Apnea Test
(HSAT, Polygram, PG)

Completed at home

Measures oxygen, air flow

In-Lab Sleep Study
(Polysomnogram, PSG)

Assesses sleep stage and other sleep disorders in addition to sleep apnea

Requires overnight monitoring in a sleep lab

During the sleep study, the number of apnea and hypopnea events per hour are counted and reported as the Apnea Hypopnea Index (AHI), the most common measure of severity of sleep apnea.

For Patients

IMPORTANT SAFETY INFORMATION

The remedē® System is indicated for moderate to severe Central Sleep Apnea in adult patients.

Your doctor will need to evaluate your condition to determine if the remedē system is right for you. You will not be able to have an MRI or diathermy (special heat therapies) if you have the remedē system implanted. The remedē system may be used if you have another stimulation device such as a heart pacemaker or defibrillator; special testing will be needed to ensure the devices are not interacting.

As with any surgically implanted device, there are risks related to the surgical procedure itself which may include, but are not limited to, pain, swelling, and infection.

Once the therapy is turned on, some patients may experience discomfort from stimulation and/or from the presence of the device. The majority of these events are resolved either on their own or by adjusting the therapy settings. The remedē system may not work for everyone. There are additional risks associated with removing your system. If you and your doctor decide to remove the system, another surgery will be required.

Be sure to talk with your doctor so that you thoroughly understand all of the risks and benefits associated with the implantation of the remedē system. Rx only. For further information, please call +1-952-540-4470 or email info@respicardia.com.
