  • Patent number: 11202874
    Abstract: A system is for alarm management in connection with a lung recruitment manoeuvre performed by a breathing apparatus on a mechanically ventilated patient. The system is configured to obtain information on at least one optimized ventilation setting for the patient, determined during the lung recruitment manoeuvre, and to automatically initiate at least one alarm setting for a period of ventilation following the recruitment manoeuvre, based on the optimized ventilation setting.

  • Patent number: 11154673
    Abstract: A ventilation system includes a breathing apparatus which provides a mechanical ventilation to a patient. The breathing apparatus is configured to perform an automated full recruitment manoeuvre, FRM, comprising a recruitment phase and a PEEP titration phase, wherein the PEEP titration phase is a phase of stepwise decrease in PEEP from a maximum PEEP level to a minimum PEEP level, via one or more intermediate PEEP levels. The breathing apparatus is configured to deliver a number of breaths at each PEEP level, and to monitor a parameter indicative of a potentially harmful level of ventilation during the PEEP titration. The breathing apparatus is further configured to automatically decrease PEEP to a lower PEEP level when the monitored parameter reaches a first threshold value.

    Abstract: A ventilation system includes a breathing apparatus which provides mechanical ventilation to a patient. The breathing apparatus is configured to perform an automated full recruitment manoeuvre, FRM, comprising a recruitment phase and a PEEP titration phase, and to determine at least one optimised ventilation setting for the patient during the FRM manoeuvre. The breathing apparatus is further configured to automatically switch ventilation mode to a predefined ventilation mode after the FRM manoeuvre, and to ventilate the patient in the predefined ventilation mode using the at least one optimised ventilation setting during a period of post-recruitment manoeuvre, post-RM, ventilation following the FRM manoeuvre.

  • Publication number: 20210213221
    Abstract: A ventilation system includes a breathing apparatus which provides a mechanical ventilation to a patient. The breathing apparatus is configured to perform, at a first point in time, an automated full recruitment manoeuvre, FRM, comprising a recruitment phase and a PEEP titration phase, the FRM being performed based on preset FRM settings. The breathing apparatus is further configured to perform, at a second and later point in time, an automated quick recruitment manoeuvre, QRM, comprising a recruitment phase but no PEEP titration phase, the QRM being performed based on preset QRM settings. The breathing apparatus is configured to initiate at least one QRM setting based on at least one FRM setting used for the FRM manoeuvre, and/or a result of the FRM manoeuvre.

  • Publication number: 20140169162
    Abstract: A medical telemetry system and method are provided for communication between an implantable medical device (IMD) and an external device (ExD). The method and system collects real-time (RT) data and non-real-time (NRT) data. The method and system segment the RT data into RT packets and the NRT data into NRT packets and load the RT and NRT packets into a shared transmit buffer in the IMD in accordance with RT and NRT bandwidth allocations and/or packet size. The method and system transmit the RT and NRT packets from the IMD to the ExD in an order loaded in the transmit buffer and adjust at least one of the RT and NRT bandwidth allocations and/or packet size based on a quality of service (QoS) characteristic.

  • Patent number: 8359095
    Abstract: In a medical system and a method for operating such a system, the system includes an implantable medical device of a patient, a programmer device, and an extracorporeal stress equipment adapted to exert a physiological stress on the patient, for automatically determining settings of a sensor for sensing a physiological parameter of the patient or for automatically determining a pacing setting of the device over a broad range of workloads of the equipment. The ingoing units and/or devices of the medical system, i.e. the implantable medical device of the patient, the programmer device, and the extracorporeal stress equipment, communicate bi-directionally with each other and form a closed loop.

  • Publication number: 20100274323
    Abstract: Telemetry data from an IMD are routinely extracted in order to perform a full prognosis of a patient's condition and to alter the IMD therapy programming if necessary. Typically, while the IMD is inside of the patient, it periodically or continuously collects and stores data into its memory. These stored data can then be extracted by a physician to an external device for further analysis. In addition to the stored telemetry data, the physician may also want to collect real-time telemetry data such as real-time IEGM data or other physiological data while the patient is in the physician's office. However, transmitting telemetry data can consume a high level of power and shorten the battery life of the IMD if not properly managed. Thus, it is advantageous to have built-in features to minimize the possibility the IMD is not transmitting and/or receiving data while it is not being monitored and/or used by the physician for a predetermined amount of time.

  • Publication number: 20100106222
    Abstract: In a method and system for establishing a wireless communication session between an implantable medical device IMD and a home monitoring device, the home monitoring device frequently sends communication-initiating signals to an IMD arranged within the body of a patient for establishing a communication session between the monitoring device and the IMD. In order to save energy, RF telemetry circuitry of the IMD is normally set in a low-power, idle mode. Occasionally, the RF circuitry will leave the low-power mode and enter an active mode in which it is able to detect a communication-initiating signal transmitted by the monitoring device. When a communication-initiating signal is detected, the IMD will respond accordingly to the monitoring device and a communication session will be established.

  • Publication number: 20100058480
    Abstract: An implantable medical device that is physically connectable to the body of a user has an information manager that manages sensitive information associated with the user or the device. A sensor is connected to the device that senses whether the device is physically connected to the body of the user, and generates a signal indicating whether the device is actually connected to the body of the user. The information manager is connected to the sensor, and is responsive to the sensor signal so as to perform information managing functions based on the signal. Among other things, fraudulent retrieval of sensitive data from the device is prevented if the device is not connected to or implanted in the body of the user.

  • Publication number: 20090187426
    Abstract: Functions of a clinician's workstation, which is a part of an implantable medical system that also includes an implantable medical device, are dynamically adapted dependent on collected patient data and/or collected data relating to operation of the implantable medical device. The adaptation can take place based on instructions provided to the workstation from a server, that is supplied with the collected data, and that processes the collected data to produce the instructions.
