LT-2 027

An AC line cord (100-240 VAC, 50/60 Hz) or a DC line cord (12 VDC) supplies electrical power to the DV54 PAP. The PAP converts the AC input voltage to DC voltage by means of an internal switch mode power supply and uses the DC voltage to power the internal electronics of the unit, such as microcontroller, motor control circuitry, blower, LCD display, etc. NOTE: The heated humidiﬁ er will not operate when the PAP uses external DC power.

The PAP produces positive pressure by spinning a reverse-curved impeller with a brushless DC motor. Room air is drawn through a ﬁ lter into the blower, pressurized in the blower, optionally passed through a heated humidiﬁ er chamber, and then discharged through a 22mm-ID, smooth-bore tube. Pressure regulation is achieved using measured pressure and ﬂ ow as feedback.

The DV54 PAP senses patient breathing by monitoring the ﬂ ow transducer signal which detects the ﬂ uctuations caused by inhalation and exhalation. The ﬂ ow transducer signal also triggers mask-OFF alerts and auto-ON / auto-OFF functionality.

In AutoAdjust mode, the DV54 software analyzes the ﬂ ow transducer signal to detect respiratory events such as apneas, hypopneas, mixed apneas, snoring, and exhale puffing as deﬁ ned by programmable settings. An onboard algorithm evaluates the detected respiratory events and adjusts the pressure as follows: The DV54 PAP increases output pressure when it detects apneas, hypopneas, and snoring events; it maintains pressure when it detects mixed events; and it decreases pressure on a regular timed interval as the number of recent respiratory events decreases.
