Technical Description
Theory of Operation
The sections that follow detail the theory of operation of each of the ve V*Home therapies. A pneumatic schematic of
each therapy is also provided.
Ventilation Therapy
Gas is drawn from the air intake, ltered for dust and particles, and ows into the accumulator. The air is mixed with
oxygen if V*Home is congured to deliver a set FiO2. The accumulator also serves as a mufer for the blower.
The gas passes through the internal ow transducer, which measures ow, and then moves through the blower and
through the bacterial lter. Gas ows through the connected patient circuit to deliver the congured Ventilation therapy.
