This is a great product! A compact pocket rescue mask with a head strap and an oxygen inlet. Features include head strap, oxygen inlet, one-way valve and the whole device is latex free! This unit can be reversed for use on infants. The device can be cleaned after a resuscitation and reused after replacing the one-way valve and filtrete. We especially like this mask because it has one of the softest "bubble" seals we've ever seen in a mask. This allows the device to be used on even the slickest manikins (CPR Prompt, ACTAR, etc) with good results. It makes CPR mask training much easier than hard "bubble" masks.
