摘要:
A breathing assistance system (1) for delivering a stream of heated, humidified gases to a user for therapeutic purposes, comprising; a humidifier unit (21) that has an inlet port and an exit port, said humidifier unit adapted to in use receive a flow of gases from a gases source via said inlet port, said humidifier unit further adapted to hold and heat a volume of water in use, in use said flow of gases passing through said humidifier unit and becoming heated and humidified, said heated humidified gases exiting said humidifier unit via said humidifier unit exit port, a delivery conduit (6) and user interface configured to in use receive said heated humidified gases from said exit port for delivery to said user, said delivery conduit having a heater wire adapted to heat the gases within said conduit, a patient end temperature sensor (15) adapted to measure the temperature of said gases flow at or close to said patient, a flow probe adapted to measure the actual flow rate of said gases steam through said system, said breathing assistance system further comprising a controller adapted to receive data from said patient end temperature sensor relating to the measured temperature, and data from said flow probe relating to said actual flow rate, said controller determining a control output in response, said control output adjusting the power to at least said heater wire to maintain or alter the temperature of said flow or gases within said conduit to achieve a desire patient end temperature at said interface (7).
摘要:
A method of acclimatizing a user to provide continuous positive airway pressure (CPAP) therapy, including operating a device for treating sleep disordered breathing (SDB) during successive treatment sessions, wherein the device provides continuous positive airway pressure during sleep, includes determining a clinically-derived full therapeutic pressure, applying a sub-therapeutic treatment pressure for the duration of a first session, obtaining responses to a series of pre-programmed patient and/or bed partner feedback questions before the start of a second session, and, based on the responses, either incrementally increasing the treatment pressure for the second session if the responses indicate that the patient is adjusting to therapy, or maintaining the treatment pressure for the second session if the responses do not indicate that the patient is adjusting to therapy.

According to one aspect of the disclosure, a control device for a medical ventilator is disclosed. The control device has a user definable medical ventilator protocol and the control device includes means for selecting a plurality of objects from a group of objects, wherein each of the objects are segments of the ventilator protocol, and each of the objects have at least one attribute. Further, the control device includes means for arranging the plurality of objects in a sequence, means for initiating the at least one attribute to define a property for each object in the plurality of objects and a processor unit configured to execute the sequence. The medical control device gives the user flexibility to define and implement a medical ventilator protocol in a faster way than possible today and for different patients and/or ventilator situations.
摘要:
Embodiments of the present invention relate to a system and method for determining a physiologic parameter of a patient. Specifically, embodiments of the present invention include methods and systems for correcting a pulse oximetry plethysmographic waveform variability measurement based on parameters that may influence the waveform variability. The corrected measurement may be used to estimate intravascular blood volume and/or fluid responsiveness of a patient.
摘要:
A system and method to control oxygen supply uses determinations whether physiological sensors and/or a subject interface appliance have been displaced in relation to a subject and/or there has been movement of the subject itself. Artifacts that may reduce the accuracy of measurements of physiological parameters, in particular related to a level of arterial oxygen saturation, may be detected through determinations pertaining to sensor displacement, displacement of the subject interface appliance and/or movement of the subject.
摘要:
According to an embodiment of the present invention, a ventilation monitoring device comprises at least one processor and at least one memory including computer program code. The at least one memory and the computer program code is configured with the at least one processor to cause the ventilation monitoring device to determine whether an intubated subject's tracheal tube is properly placed by receiving an indication of a subject's breath from at least one sensor.
摘要:
Drug delivery devices (1) are described that include sensors (9) and processing circuitry (11) that can detect operating events, such as flow rates and drug delivery, in various types of inhalers, such as dry powder inhalers, metered dose inhalers, nasal inhalers and nebulisers. The information determined by the processing circuitry can be used to provide feedback to the user or can be stored or transmitted for subsequent analysis. This information can be used to improve clinical trials by providing information about the way in which the inhalers under test are being used.
摘要:
A system and method for monitoring resuscitation and respiratory mechanics of a patient is provided. A pressure sensor detects air pressure within an air-flow path of a resuscitator and generates a first detection signal in response thereto. A flow-rate sensor detects the flow-rate within the air-flow path and generates a second detection signal In response thereto. A processor receives and processes the first and second detection signals using an algorithm to identify a ventilation rate, a lung pressure, and an air volume corresponding to the respiratory air. A report is generated of real-time feedback about respiration of the patient that includes the ventilation rate, lung pressure, and air volume.
