Seth and his BiPAP.....

  Seth mask is called a ResMed mirage nose/mouth mask. His BiPAP machine is sitting beside him. His rate is 9/4 

  Seth's mask is cool. It has a "pull cord" (it is the string that's hanging by the tube)  all the straps are velcro and adjustable so it can change as his head size changes. Seth can pull the pull cord to take off the mask if he needs to.
