A method for managing pressure in a breathing assistance system configured to provide breathing assistance to a patient via a patient connection system is provided. The method may include receiving one or more first pressure sensor signals from a first pressure sensor, and analyzing the one or more first pressure sensor signals. Based at least on the analysis of the one or more first pressure sensor signals, either the first pressure sensor or the second pressure sensor may be selected for use in controlling the breathing assistance provided to the patient, and the breathing assistance provided to the patient may be controlled based at least on signals from the selected pressure sensor.

Breathing assistance system with multiple pressure sensors

A method for providing battery security in a breathing assistance system configured to provide breathing assistance to a patient is provided. A battery security system of the breathing assistance system receives battery data from a battery received in the breathing assistance system, and analyzes the received battery data to determine whether the battery is approved for use in the breathing assistance system. If the battery is determined to be approved for use in the breathing assistance system, the battery is allowed to provide power to the breathing assistance system. If the battery is not determined to be approved for use in the breathing assistance system, the battery is prevented from providing power to the breathing assistance system.

Battery management for a breathing assistance system

A system for managing a supplemental gas supply in a breathing assistance system configured to provide breathing assistance to a patient includes a temperature sensor and a control system. The temperature sensor is configured to measure a temperature associated with a breathing assistance system configured to deliver a first gas and a supplemental gas toward a patient. The control system is configured to automatically control the flow of the supplemental gas based at least on the monitored temperature.

Supplemental gas safety system for a breathing assistance system

A system for wireless data communication for use with a breathing assistance system configured to provide breathing assistance to a patient is provided. The system includes a wireless notification module, one or more wireless repeaters located remote from ventilation system, and a wireless receiver located remote from the one or more wireless repeaters. The wireless notification module is coupled to a ventilation system and configured to wirelessly transmit data received from the ventilation system. The one or more wireless repeaters are configured to receive the data wirelessly transmitted by the wireless notification module, and wirelessly transmit the received data. The wireless receiver is configured to receive the data wirelessly transmitted by the one or more wireless repeaters, and communicate the received data to a user remote from the ventilation system.

Wireless communications for a breathing assistance system

The object of the invention is a device for supplying respiratory gas to a patient according to respiratory cycles, comprising a gaseous flow rate generator provided with a turbine with low inertia and high nominal speed, a first circuit called a supply circuit for the gaseous flow toward a respiratory mask or an intubation means of the patient, means for measuring pressure and/or measuring flow rate of the gaseous flow, computation means for parameters of pressure and/or flow rate, and means for controlling the speed of rotation of the generator, characterized in that the measuring means, the computation means and the speed control means coact automatically to control the speed of rotation of the turbine as a function of the inspiration and expiration phases and as a function of patient pressure signals and/or inspiration flow rate signals.
