Publication number: 20230080441Abstract: A respiratory treatment device includes a blower for providing flow of breathable gas to a patient and one or more accessory devices. The respiratory treatment device includes active power management to distribute power from a power source that does not have sufficient power to simultaneously power the blower and the accessory devices. The active power management prioritizes power to the blower and limits, based on current measurements of the blower and the accessory devices, the power supplied to the accessory devices to keep the sum of the power drawn at or below the capacity of the power supply. When additional power is available, due reduced power consumption of the blower, the power to one or more accessory devices is raised beyond a target in order to compensate for when power was not supplied to the one or more accessory devices.Type: ApplicationFiled: November 15, 2022Publication date: March 16, 2023Inventors: Andrew Roderick BATH, Rudi VOON, David CREUSOT, Dmitri Anatolievich DOUDKINE, Jianhua ZHU, Adam PANARELLO
