Replacement nasal cushion for the Philips Respironics Pico nasal CPAP mask.
Three sizes available: Small/Medium (#1104936), Large (#1104937), and Extra Large (#1104938).
The patented "tip of the nose" cushion results in minimal contact and a superior seal. In addition to the low profile, the cushion features "auto seal groove technology" which accommodates your every move. In essence the grooves at the top and bottom of the cushion allow the cushion to flex in and out. This flexing action helps to maintain a good seal even while you move around in your sleep.
