 Viraj and I in this video will demonstrate the use of our home pulse oxygenator. So this is the machine it's battery operated has a battery chamber at the back which houses two AAA batteries. So it opens like a clip you turn on the machine and there is the LED sensor the finger is inserted into the sensor that's the wrong finger to insert because it has nail paint on it and it's a longer nail so you insert a finger without nail paint with a shorter nail make sure the machine is on allow it to calibrate and it's doing its reading and there is the oxygen saturation and the pulse rate simple as that
