At Biostrap, we are proud to be using clinical-grade sensors for our device.
As part of our ever-expanding offering, we are excited to now include on-demand pulse reports you can take right from the app! Results are emailed in a PDF file, and easy to share with your healthcare provider or loved ones.
To run a report, go to the Record page and select one of the two options, and the Start button:
- 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)
When the report is finished analyzing, your PDF results will be sent via email.
How to record and interpret the pulse reports
First, you will see your Biometrics taken during the Pulse 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.
This represents an RR cluster Plot which is a representation that can give quick insight into irregularities or odd rhythm patterns. Ideally, a user will want to see the cluster of points very close together with points farther outside the cluster representing irregularities in the rhythm.
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 in 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.
