POWER MANAGEMENT IN RESPIRATORY TREATMENT APPARATUS
First Claim
1. A respiratory treatment device comprising:
- a flow generator to provide a flow of breathable gas to a patient;
an accessory apparatus;
a power supply unit; and
a controller coupled with the flow generator, the accessory apparatus, and the power supply unit, the controller being configured to control offsetting of peak power operations of the flow generator and the accessory apparatus as a function of detecting a patient respiratory cycle by the respiratory treatment device.

Abstract
A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.
