Plethysmograph Helps You Get More Reliable Readings
Each wave corresponds to a heartbeat and the wave amplitude corresponds to the amount of blood detected by the pulse oximeter. Higher wave amplitude means stronger pulse strength. For best results, take your readings when the height of the wave amplitude is consistent throughout (the waves look uniform). This is when the pulse oximeter detects constant blood flow and gives you the most reliable read.
