During the Live O2 session my pulse oximeter reading rises to 99 then dips to 96- 93, Is that normal?

This is with­in the scope of nor­mal LiveO2 expe­ri­ences. When the oxy­gen sat­u­ra­tion drops dur­ing the train­ing ses­sion this is a detox event. In oth­er words, a por­tion of your body’s micro-cir­cu­la­tion is open­ing an area that has been closed off. This is a good sign that you are pos­i­tive­ly affect­ing the micro-cir­cu­la­tion switch­ing mech­a­nism and is also very com­mon dur­ing the 15 minute pro­to­col. When this hap­pens for the first few times about half of indi­vid­u­als notice a smell they do not con­sid­er nor­mal for them. It can come in the form of smelly sweat, breath, urine, bow­el move­ments etc. It is your sys­tem detox­ing and it is hard to say what exact­ly it is, but the impor­tant thing to keep in mind is that it is leav­ing your body. Most expe­ri­ence this once or twice and then it goes away or becomes less intense and even­tu­al­ly clears.

The video here men­tions this around the 2:30 time mark. It is a pret­ty good expla­na­tion of what is hap­pen­ing in your tis­sues and detox tides.
