Abstract: A gas cylinder monitoring system is disclosed having a gas cylinder for receiving and distributing gas contained therein, a first monitoring system associated with the gas cylinder operable to monitor data associated with the gas cylinder and having a transmitter operable to broadcast the data at a controlled time and/or time interval in a discrete advertisement package, and a second monitoring system associated with one or more locations in which the first monitoring system may reside and having a receiver operable in a first mode to receive the advertisement package broadcast from the first monitoring system when the second monitoring system is within range of the first monitoring system.

Abstract: There is provided an apparatus for detecting the deteriorating health of a patient receiving gas from a respiratory device. The apparatus comprises a sensor unit configured to monitor a flow rate or pressure of a gas that is flowing in a pipe that connects the respiratory device to a gas delivery device worn by the patient, and a processor configured to measure a respiratory rate of the patient based on variations in the flow rate or pressure of gas in the pipe and to implement a trend analysis of the measured respiratory rate. The processor is configured to generate a warning when it determines that there is an upward trend in the measured respiratory rate and that a magnitude of the trend exceeds a threshold.

Abstract: The present invention provides a monitoring apparatus for an outlet of a vessel storing gas under pressure. The monitoring apparatus comprises a flow control valve movable to a position between a fully open position and a fully closed position to adjust a flow of gas from the outlet of the vessel, a valve position detector connected to the flow control valve to detect the position of the flow control valve, an internal pressure sensor to sense an internal pressure Pint(t) of the gas in the vessel at different times, a processor, a memory and an alarm. The processor calculates an actual rate of change in pressure dPint/dt of the gas in the vessel over time, and compares dPint/dt with an expected rate of change.
