No reading yet
Calibrate once against a cuff, then measure.
Heart rate--bpm
Transit time--ms
Clean beats--
Measure
Sit still with the finger sensor at heart level. A reading takes 30 seconds.
Signals
ECG Chest vibration Finger pulse Transit time per beat
Calibrate
Take a cuff reading while recording 30 seconds in each situation. The fit turns transit time into pressure for this person.
Pressure against transit time
Systolic Diastolic
Calibration
SBP = a / PTT + b
DBP = c / PTT + dPTT in seconds, pressure in mmHg
Record at least two situations to fit the calibration.
