How does the Pulse Oximeter work?

The Pulse Oximeter is includ­ed so that you may mon­i­tor both your heart rate and your oxy­gen sat­u­ra­tion lev­els in accor­dance with the pro­to­cols for adap­tive con­trast train­ing. To use it, put it on your index fin­ger and push the but­ton on the top to acti­vate it when work­ing out to check these stats at a glance. The top num­ber is your oxy­gen sat­u­ra­tion lev­el. On a healthy, active per­son this will be between 95–97 before you start using the oxy­gen. As you are using the oxy­gen this num­ber will like­ly go up to 99 and when you go into high alti­tude mode it will prob­a­bly drop below 91, pos­si­bly even to 75.

The bot­tom num­ber mea­sures your pulse/heart rate. When exer­cis­ing, a good tar­get is to try and get it up past 120 BPM. When you are on LiveO2 mode (oxy­gen rich) it will prob­a­bly be less. When you go into Adaptive Contrast (AC) mode (lim­it­ed oxy­gen) it will enable you to get your heart rate up so the num­ber will go high­er. Getting your heart rate up when using alti­tude con­trast is what sets the LiveO2 AC apart from the LiveO2, as the high­er your heart rate, the more ‘squirt pow­er’ the oxy­gen has to pen­e­trate your sys­tem when you go back to the live (oxy­gen rich) mode.

Individual num­bers will vary accord­ing to age and fit­ness lev­el, as well as indi­vid­ual phys­i­ol­o­gy dif­fer­ences.
