This disclosure describes systems and methods for providing novel back-up ventilation. Further, this disclosure describes systems and methods for delivering ventilation when exhalation pressure and/or exhalation flow are unknown or unreliable by the ventilator.

Methods and systems for ventilation with unknown exhalation flow and exhalation pressure

This disclosure describes methods and apparatus for indicating battery cell status on a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide methods for indicating battery cell status on the exposed exterior of a battery assembly pack both when the battery is in use and when the battery is not in use during mechanical ventilation. Embodiments utilize power from the ventilator as well as power from the battery pack itself to light the indicators during periods of battery use and non-use, respectively. Embodiments described herein further seek to provide an apparatus indicating battery cell status on the exposed exterior of the battery pack assembly during mechanical ventilation. Embodiments described herein further seek to provide an apparatus for a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide a system for a ventilation system with an inserted battery pack assembly.

A redundant power supply connected to a common load is provided. Each power supply is connected to the common load through a series of MOSFET pairs. Each MOSFET in a MOSFET pair is individually controlled to reduce power consumption as well as the need for heat sinks on discrete diodes. Moreover, by providing individually controllable MOSFETs the present invention is capable of switching between power supplies without shorting the power supplies or having a significant drop in bus voltage.
