At Biostrap, we are proud to be using clinically reliable sensors in our device.
Besides monitoring your physiology during sleep, you can also have a snapshot look at your health with our on-demand pulse reports. Results are emailed in a PDF file, and are easy to share with your healthcare provider or loved ones.
To run a report, go to the Record page and check "Email me report" under Biometrics, select one of the two options and select "Record"
- Pulse Report (2-minute scan)
- Comprehensive Pulse Report (5-minute scan)
Insider tips for the best possible report:
- Stay completely still and try to relax during the full reading
- Prevent outside light from interfering (you can cover your wristband with your sleeve or a piece of clothing)
When the report is finished analyzing, your PDF results will pop up on your screen and you can select to view the report in app. The report will also be saved in your Timeline and sent to the email you provided prior to recording the pulse report.
How to record and interpret the pulse reports
First, you will see your Biometrics taken during the Pulse Report recording compared to your last 30-day average.
Next is a visual representation of the PPG signal and the heartbeat data over the time duration. It is broken into 30 portions for the regular Pulse Report and 60-second portions for the Comprehensive Pulse Report.
Each peak in the graph is a heartbeat. If there are 60 heartbeats in a 60-second session then your heartbeat was 60 BPM. Using the RMSSD method, we measure the distance between successive heartbeats and use that data to calculate your RR-interval which is then used in producing your HRV, Oxygen Saturation and Respiratory Rate.
An ideal graph will show clear and successive peaks. While artifacts may show if excessive movement or ambient light is present.
The next graph in the report is the RR - Tachogram.
This represents the speed of each RR-interval and shows the consistency of your pulse. Ideally for the time duration, having a consistent and relatively straight line is good. While having points laying much higher or lower in the line tend to recognize irregularities in your heartbeat.
The next graph is the PoinCaré Plot.
Frequency Domain Analysis
This shows you the distribution of your data split into High Frequency(HF), Low Frequency (LF) and Very Low Frequency (VLF). These measurements give an idea of the autonomic balance between your sympathetic and parasympathetic nervous systems.
With the comprehensive pulse report, we will aggregate the data to give you an idea of your Arterial and Peripheral Elasticity. Increased stiffness can be associated with the development of cardiovascular disease.
Arterial Elasticity is a measure of how elastic or stiff your arteries are. This factors into one's blood pressure and is a contributing factor to a healthy sympathetic nervous system. Your sympathetic nervous system regulates your “Flight-or-Fight” response and how your body reacts to stress.
Peripheral Elasticity is a measure of the elasticity of the peripheral veins. Opposite of arterial elasticity, peripheral elasticity reflects your parasympathetic nervous system and regulates how quickly your body can return to a resting state.
