What Is Sleep Disordered Breathing?
Sleep Disordered Breathing is a general category for abnormal breathing patterns during sleep. The two main types are Obstructive Sleep Apnea, when the upper airway collapses during sleep (associated with snoring), and Central Sleep Apnea, when your brain does not send the correct signals to your diaphragm.
How Can I Tell If It Is Obstructive Apnea Or Central Sleep Apnea?
You need to undergo a sleep study to determine if you have sleep disordered breathing and if your apnea is predominantly Central Sleep Apnea or Obstructive Sleep Apnea. During a sleep study, your breathing patterns are measured so that your doctor can determine the next steps with you.
Could I Have Central Sleep Apnea?
1 in 3 people with heart failure have CSA. If you feel very tired or fatigued during the day, wake up often during the night, or have poor memory, difficulty concentrating, an irregular heart beat or heart failure, ask your doctor if you are at risk for Central Sleep Apnea.
How Is Central Sleep Apnea Diagnosed?
Central Sleep Apnea diagnosis is based on a clinical sleep study that can be performed at home or overnight at a sleep center. Symptoms of CSA can be similar to the symptoms of heart failure. That is why discussing CSA with your doctor is so important to know if you are at risk.
During a sleep study, external testing devices monitor the body’s oxygen, airflow, chest and abdominal movement during sleep. The study determines if you have Sleep Disordered Breathing and whether your primary type of apnea is predominantly Central Sleep Apnea or Obstructive Sleep Apnea.
At home testing can be done using a pulse oximeter overnight. Results can indicate sleep apnea, but further testing is needed to distinguish the type of apnea. Another at home option is sleep testing devices which can distinguish Central Sleep Apnea from Obstructive Sleep Apnea. An observed overnight sleep study performed at a sleep center may offer additional insight through sleep and leg movement monitoring.
How Is Central Sleep Apnea Treated Today?
Current therapies for CSA include oxygen and mask-based therapies like continuous positive airway pressure (CPAP) and adaptive servoventilation (ASV) devices. These options can improve CSA, but are limited by issues with patient compliance, ease of use and tolerability. The remedē® System is designed to treat the cause of the disease by replacing the missing signal from the brain to initiate breathing and restores natural breathing…one breath at a time™.
How Is The Device Placed?
The remedē® System is placed by a cardiologist without the use of general anesthesia. A neurostimulator is placed beneath the skin on either the right or left chest below the clavicle similar to a pacemaker placement. The lead is positioned within a vein close to the phrenic nerve. The neurostimulator delivers small electrical pulses, via the lead, to the phrenic nerve. The electrical pulses create a diaphragmatic response restoring a more natural breathing pattern during sleep.
