What We Measure in a Session

Sound Recording

Sleepcontrol records the sounds picked up by the mobile phone during the night and analyzes them, the results have a high dependence on the interference of other sounds in the night , the recording quality of the mobile phone used and the place where the mobile phone is placed during the night (preferably on the nightstand upside down). The reliability of the data obtained is high, but not 100%, it gives us a tendency that allows us to draw the approximate scenario of the user, since the conditions once the first one can be a reference for the following sessions, of improvement or not . From these recordings we get:

  • Number of Snoring

Sleepcontrol analyzes the recordings and by frequency Who emits snoring lists these episodes and reflects them in a final summary per session. Reflecting them in snoring time.

  • Obstructive Apneas

Sleepcontrol analyzes the sound and detects those possible obstructive apneas during snoring, which is detected when after a snoring the user takes between 10sg and 50sg to have another snoring, it is a complex exercise that added to the interferences listed above that can be had we want this value to be taken with Prudence, must be contrasted with other tests, we provide the connection with our approved pulse oximeter that allows us to get more information about these episodes.

  • Maximum volume

We record the maximum value of the sound recorded during recording, our filters pick up snoring but similar frequency interference can alter the results.

  • Medium Volume.

It marks the average value of snoring detected by SleepControl.

Pulse Oximeter incorporation

With this element SleepControl goes one step further and reflects a scenario closer to the reality of the user in his sleep disorders, if he had them, since the Blood Oxygen and the pulse are measured, with these values ​​added to the recording and the data provided by the user session, We have a scenario very close to the realization. For each session we will get:

  • Blood Oxygen Saturation

Pulse oximetry is a non-method invasive, which allows determining the percentage of oxygen saturation of hemoglobin in the blood of a patient with the help of photoelectric methods.

To perform this technique, place the technique pulse oximeter, in a part of the body that is relatively translucent and has good blood flow, for example the fingers. The pulse oximeter emits lights with wavelengths, red and infrared that pass sequentially from a transmitter to a photodetector through the user. The absorption of each wavelength caused by arterial blood (pulsatile component) is measured, excluding venous blood, skin, bones, muscle, fat. With these data it will be possible to calculate the oxygen saturation in blood.

It gives us the graphic line in the oxygen saturation time in blood, indicating those oxygen depletions in blood higher than 5%, above normal until that time, with a green dot and counting the total number of them in the session. It also counts the time the user spends with a blood oxygen below 90%.

  • Frequency Cardíaca

The pulse oximeter does not offer a heart rate reading that SleepControl stores every second and graphically analyzes.
