Makes use of sensors that can measure both your breath rate (sonar, Sleep phaser, and Polar H10), or your blood oxygenation (oximeter, some wearables). A turquoise line in your sleep graph exhibits breath fee - see Figure 1, "Breath-charges in sleep graph". A blue line on your graph depicts oxygen information - see Figure 2, "BloodVitals SPO2 device information in sleep graph". Whenever a major dip in worth occurs, a O2 image will likely be proven within the graph. It is a respiratory disturbance. From those disturbances, we compute your Section 1, "RDI" value. Monitoring respiratory disturbances is vital for sleep apnea detection. Respiratory Disturbance Index is the average depend of respiratory disturbance episodes per hour. RDI below 10 is taken into account normal, among the disturbance occasions measure could also be faults of the sensor and how tight the sensor is round your finger as an example. RDI from 10 to 15 is considered a mild respiratory disturbance. |
