Measuring Directions

1. Length mea­sure­ments are used to deter­mine the size of the LiveO2 mask that will best fit you. for mea­sure­ment, the indi­vid­ual facial mus­cles should be relaxed and jaw closed.
2. Place the gauge tip to the deep­est point of the nasal root depres­sion (sel­l­ion) and note the size indi­ca­tion where the bot­tom of the chin exits the gauge.

If you are between sizes, we rec­om­mend you use the small­er size.
