This document describes a system for determining positioning of an intubation tube in a patient. The system can include a first acoustic sensor configured to be disposed to listen to one of a lung and a stomach of the patient and to provide a first signal. The system includes a signal processing unit, coupled to the first acoustic sensor, configured to analyze spectral components of the first signal and determine whether a frequency of the spectral components of the first signal are characteristic of sounds induced by ventilation via the intubation tube of airflow to the lung or the stomach of the patient.

A ventilator system includes a ventilation device, and is configured to operate in a passive mode configured to transmit ventilation data in response to requests from a ventilation management system, or an active mode configured to automatically transmit ventilation data as the data becomes available. The system receives ventilation system data associated with operation of the ventilation device, modifies one or more operating parameters of the ventilation device based on the received ventilation system data, receives ventilator data associated with the ventilator device, determines an alarm associated with the ventilator device or a patient based on the received ventilator data and, responsive to determining the alarm, sends the alarm to a beginning of a transmission queue for transmitting the ventilation data to the ventilation management system, wherein the alarm is communicated over the network prior to other ventilation data in the transmission queue.

An ultrasound scanning apparatus comprises an ultrasound scanning unit, an ultrasound controller for controlling the operation of the ultrasound scanning unit, detecting the operation state of the ultrasound scanning unit, generating a first enable signal when detecting that the operation state of the ultrasound scanning unit is transferred from an operating state to a non-operating state and generating a second enable signal when detecting that the operation state of the ultrasound scanning unit is transferred from the non-operating state to the operating state, and an enable output end for transmitting the first enable signal or the second enable signal to the breathing machine to control the running of the breathing machine.

A patient management system for providing patient queues of patient reports to users includes communications circuitry configured to receive first physiological information from monitoring medical devices being worn by a first plurality of patients and receive second physiological information from therapeutic medical devices being worn by a second plurality of patients. Each of the monitoring medical devices is configured to sense one or more predetermined physiological parameters of its respective patient. Each of the therapeutic medical devices is configured to monitor its respective patient for a predetermined physiological condition and provide a treatment. The patient management system also includes at least one processor configured to prepare a plurality of monitoring patient reports, prepare a plurality of therapeutic patient reports, generate a patient queue based on the pluralities of monitoring and therapeutic patient reports, and provide the patient queue to an end user computing device via the communications circuitry.

A compliance monitoring module for an inhaler comprising: a miniature pressure sensor, a sensor port of said sensor being configured to be pneumatically coupled to a flow channel of said inhaler through which a user can inhale; a processor configured to: receive data from a sensing element of the pressure sensor; receive data from a mode sensor configured to detect when the inhaler changes from an inactive mode to an active mode; and based on said data from said pressure sensor sensing element and said data from said mode sensor, compile a compliance report; and a transmitter configured to issue said compliance report.

It is determined, during monitoring of a patient, that a plurality of alarm conditions has been initiated. The alarm conditions characterize a measurement by and/or operation of at least one medical device and have an associated grade among a plurality of prioritized grades. Thereafter, alarms can be generated that corresponding to some or all of the plurality of alarm conditions such that among concurrent active alarms: (i) an alarm corresponding to an alarm condition having a highest priority grade is conveyed at a first level upon initiation and, if such alarm condition remains active for a pre-defined time period, at the first level upon expiration of the pre-defined time period, and (ii) alarms corresponding to alarm conditions having equal or lower priority grades than the priority grade of the current highest priority grade alarm condition are conveyed at a second level, the second level being different from the first level.

A method for determining a chance to enable a zeroing of gas analysis is disclosed herein. The method includes emitting radiation, and receiving emitted radiation, the received radiation comprising a first wavelength range absorbed by the at least one desired gas component and one or more disturbing factor, and a second wavelength range absorbed by the disturbing factor, the first wavelength range differing from the second wavelength range. The method also includes providing to a processing unit a first signal data indicative of a concentration of the at least one desired gas component and absorption of the disturbing factor, and a second signal data indicative of absorption of the disturbing factor. The method also includes determining a stability of the first and second signal data as a function of time, and if they are substantially stable enabling the zeroing to improve a measurement accuracy.

A first medical device can receive a physiological parameter value from a second medical device. The second physiological parameter value may be formatted according to a protocol not used by the first medical device such that the first medical device is not able to process the second physiological parameter value to produce a displayable output value. The first medical device can pass the physiological parameter data from the first medical device to a separate translation module and receive translated parameter data from the translation module at the first medical device. The translated parameter data can be processed for display by the first medical device. The first medical device can output a value from the translated parameter data for display on the first medical device or an auxiliary device.

Features for assessing patient compliance with therapeutic usage of an inhaler, such as a nebulizer, are disclosed. Nebulizer therapy accessories include mouthpiece, mask and adaptor (i.e. an attachment to a mouthpiece or mask) that may be coupled with the nebulizer. The nebulizer therapy accessory includes at least one sensor that detects a physical parameter generated by a user's body and generates a signal. The signal is used to determine therapy compliance, which may be communicated to the patient and/or the patient's physician.

A flow sensor comprises a flow restriction disposed within a passage such that a fluid passing through the passage must pass through the flow restriction. The flow sensor also has an upstream pressure sensor coupled to the passage at a point upstream of the flow restriction and configured to measure and provide an upstream pressure of the fluid within the passage, a downstream pressure sensor coupled to the passage at a point downstream of the flow restriction and configured to measure and provide a downstream pressure of the fluid within the passage, and a temperature sensor coupled to the passage and configured to measure and provide a temperature of the fluid within the passage. The flow sensor also includes a flow sensor processor coupled to the upstream and downstream pressure sensors and the temperature sensor and configured to accept measurements therefrom and calculate a compensated flow rate based at least in part on the measured pressures and temperature.
