Can PPG measure respiratory rate?

The PPG waveform contains information about a wide range of physiological parameters such as HR, heart rate variability (HRV), oxygen saturation (SpO₂), vascular tone, blood pressure, cardiac output and respiration (Shelley, 2007).

How can you calculate respiratory rate?

Your respiratory rate is also known as your breathing rate. This is the number of breaths you take per minute. You can measure your breathing rate by counting the number of breaths you take over the course of one minute while you're at rest.

How do you convert PPG to heart rate?

BPM=(Sampling Rate/(peak(i+1)-peak(i)))*60; Do the FFT transform for a set of data. Then find the peak from 0.5-2.5Hz. Finally multiply that peak's frequency with 60s.
