Puffin, a member of our CPAP Forums, demonstrates his Respironics Remstar M-Series CPAP Machine in this great (prize-winning) video. He clearly demonstrates all the kit involved including machine, mask, hose, humidifier and cables.
User-contributed videos like this one are great to get a real idea of perspective in terms of product size and usability. Many manufacturers nowadays produce short product videos but they are always from a sales perspective, obviously. A video by a real CPAP users shows the machine in its natural habitat, the bedroom. It illustrates the size in comparison to a pillow or bedside table and shows where the tube would go.
Thanks Puffin for the great contribution!
