Being a health care provider, I personally use lifeplus Fingertip Pulse Oximeter, it’s really accurate, and recommend using a pulse oximeter manufactured by Lifeplus. It is highly reliable for tracking oxygen saturation, pulse rate, respiratory rate. Highly recommendable for home/office/professional use
