摘要:
A ventilator system (110) includes: an inhalation filter (120) configured to receive and filter a gas; a humidifier (130) connected to the inhalation filter and configured to adjust a humidity of the filtered gas; a dual-limb patient circuit connected to a patient and configured to supply ventilation to the patient, the dual limb patient circuit including an inspiratory limb connected to the humidifier and configured to supply the filtered gas to the patient and an expiratory limb configured to receive an exhaled gas from the patient; a condenser (140) connected to the expiratory limb, the condenser being configured to cool and remove moisture from the gas from the patient; and an expiratory filter (150) connected to the condenser and configured to filter the cooled gas from the condenser.
摘要:
A method and apparatus provide closed-loop control of the operation of a ventilator device based on physiological parameters received from and/or through a patient monitor device, which is a separate and discrete device from the ventilator device.

Provided are systems for humidifying gas delivered to a patient. A humidifier unit (107) is provided located proximal to a patient interface (105) of a patient circuit (103). The humidifier unit includes a chamber that receives water from a water source (109), a heat source disposed within the chamber, a water flow sensor (113), an output temperature sensor (117), an output humidity sensor, and/or other sensors. A controller (119) receives flow data relating to water being provided to the chamber and temperature data relating to the temperature of the humidified gas, humidity, and/or other data. The controller further adjusts a flow of water being provided to the chamber based on the flow data and/or a heat output of the heat source based on the received data.

A ventilator system (100/200/300/400) includes an integrated blower (130/230/330). In one case, the ventilator system includes: an inspiration port (122/222/322) for connection to an inspiratory limb (112/212/312) of a dual-limb patient circuit (110/210/310), and an expiration port (142/242/342) for connection to an expiratory limb(114/214/314) of the dual-limb patient circuit;a gas delivery device(120/220/320) connected to the inspiration port to supply a pressurized flow of gas to the inspiration port to generate a positive pressure; and a blower having an inlet (132/232/332) that is operatively connected to the expiration port and configured to be controlled to selectively supply a negative pressure level between 4 and 120 cmH 2 O to the expiration port, and an outlet (134/234/334) to exhaust gas received from the expiration port. In another case, the ventilator system includes a blower to generate positive pressure/flow to augment flow for noninvasive ventilation.
摘要:
A pressurized flow of breathable gas is delivered to the airway of a subject in accordance with a therapy regimen. The therapy regimen may be designed to maintain oxygenation of the subject. The therapy regimen dictates levels of fraction of inspired oxygen and/or positive end expiratory pressure to maintain a therapeutically beneficial level of oxygenation in a feedback manner. Within the therapy regimen, changes made to fraction of inspired oxygen and/or positive end expiratory pressure automatically and dynamically are constrained by user configured constraints such as the maximum incremental change, amount of time between adjustments, or the maximum rate of change This may provide a level of customization of the automated control of the therapy regime for individual subjects.
