How Pulse Oximeter measures blood Oxygen level ? | How it works ?? | HINDI

I have handpicked the best Pulse Oximeters, you should check them out: 1) BPL Pulse Oximeter: https://amzn.to/3gLdG0R 2) Dr. Trust Pulse Oximeter: https://amzn.to/3eGiH87 Blood Glucose Meter: 1) Accu-Chek Active Blood Glucose Meter Kit: https://amzn.to/3uutUiM Blood Pressure Monitor: 1) Omron HEM 7120 Fully Automatic Digital Blood Pressure Monitor: https://amzn.to/3toomGA This video explains the detailed working of a pulse oximeter in simple language by using diagrams and suitable examples. I have explained how the oximeter measures blood oxygen level by using light. 2 LED lights are used in the pulse oximeter of different wavelengths, each wavelength plays its own role that is Oxygenated haemoglobin absorbs more Infrared light (IR) where deoxygenated haemoglobin absorbs more RED light. these lights are emitted in the skin which passes through the blood and that refracted light is sensed by the photodiode, both lights are emitted alternately in a sec for collecting Oxygenated haemoglobin and Deoxygenated haemoglobin by sensing the intensities of the refracted IR and RED lights. Then this data is processed and takes the ratio of Oxy HB and Deoxy HB and then it is converted into a percentage. #oxygen #pulseoximeter #explained Subscribe:    / @shivamrane   Follow me on Instagram:   / shivamm_rane
