Should I use Sleep Analyzer if I wear a pacemaker?

Yes, you can use Sleep Analyzer if you wear a pacemaker or other internal medical device.

Should I use the device if I have a CPAP machine?

Yes, Sleep Analyzer can be used with a CPAP machine. Please note that the CPAP machine should be placed next to the bed to ensure proper sleep and snoring tracking. 

Should I use the device while I am pregnant?

Yes, there are no known risks associated with pregnant women using Sleep Analyzer.

Should I use the device to monitor the sleep of my child?

Sleep Analyzer has been tested on adults (from 18 years old in the EU, 21 years old in the US). Unfortunately, we cannot guarantee sleep accuracy for children.

Should I use the device if the device becomes warm?

Yes, it is normal for the Sleep Analyzer to become warm, particularly at night. This is in part the result of the device being in between the mattress and bed frame, making it difficult for heat to dissipate. Keep in mind, however, that the Sleep Analyzer was designed to operate under these conditions.

Are there any contraindications to the use of the Sleep Apnea Detector of the device?

Sleep Apnea Detector is not indicated for use on patients with the following conditions:

  • Arrhythmia, as the device also analyzes changes in the heart frequency to detect apnea and hypopnea events. Since arrhythmias are often characterized by irregular heartbeats, these conditions may mislead the device.
  • Cardiac insufficiency (heart failure), as this condition may be associated with irregular heart rhythm and breathing which may mislead the device and has not been tested.
  • Chronic obstructive pulmonary disease, such as nocturnal asthma, has a distinctive breathing pattern with prolonged expirations, which the device may confuse with apnea or hypopnea breathing patterns, incorrectly increasing the AHI.
    Chronic hypoventilation observed in chronic obstructive pulmonary disease or neuromuscular diseases (Charcot’s disease) has a different breathing pattern than apneas, with prolonged shallow amplitude of breathing.

Other conditions may also negatively affect the performance of the device. These include disorders such as periodic limb movements in sleep and restless legs syndrome, which could create interfering signals, or non-respiratory sleep disorders that result in fragmented sleep.
