One key objective of a sleep study is to find out the frequency of event occurrences or AHI.ĭate/Time: Date and time when the measurement started and completed. File -> Connect Device Select Com3 (or other USB port ) Click on View device stored data only. Indicators: Signal strength, battery status and finger out. Definitions for the pulse rate and SpO2 events are defined below the summary data above the graphs. Data displayed: Oxygen saturation, pulse rate, pulse indicator and bar graph. The thresholds and duration are defined in Analysis Setup under Options. That being said your wise to keep tabs on your O2 levels. Desaturation can be caused by Apnea events, but there is no way to measure AHI with oxygen readings. Your readings sound like your desaturation levels aren't critical. I recall references on the Forum (that ChoiceMMeds MD300i which SleepyHead Oximetry area refers to), and Kevin Coopers enquiries of the manufacturer, suggests the MD300W314 model uses the same. Event: An event occurs when the reading falls outside a predefined range and for a given duration. The readings usually are fairly close to what you'd get in a hospital. For the ChoiceMed oximeter, SleepyHead will only (soon) accept a dat file because nobody has documented the USB protocol it uses. ![]()
