Dead space
information
Physical dead space is the empty volume of the mask
to the end of the swivel.
It is 101.7 mL.
Therapy pressure 2 to 30 cm H2O
Compliance Mask compliance between 5 cm H2O and 15 cm H2O is
less than 1.57 mL/cm H2O
Resistance Drop in pressure measured (nominal)
at 50 L/min: 0.8 cm H2O
at 100 L/min: 3.1 cm H2O
Sound DECLARED DUAL-NUMBER NOISE EMISSION
VALUES in accordance with ISO 4871. The A-weighted
sound power level of the mask is 40.6 dBA, with
uncertainty 4 dBA. The A-weighted sound pressure
level of the mask at a distance of 1 m is 32.6 dBA, with
uncertainty 4 dBA.
