Abstract: Various methods and systems are provided for performing nasal high flow therapy. In one example, a method for respiratory support includes: delivering an air and oxygen mixture for nasal high flow therapy to a patient at a flow setting, the flow setting determined based on a peak inspiratory flow obtained during a previous, spontaneous breathing mode during mechanical ventilation of the patient. The flow setting may be a flow rate of a heated and humidified mixture of air and oxygen delivered via a high flow nasal cannula.

Abstract: A patient transfer device is configured for use with at least one host device which is capable of providing respiratory support to a patient. The patient transfer device includes an inspiratory port and an expiratory port which are configured to pneumatically connect to the host. An inspiratory connection is pneumatically connected to the inspiratory port and an expiratory connection is pneumatically connected to the expiratory port. An inspiratory valve is coupled between the inspiratory port and the inspiratory connection and expiratory valve is coupled between the expiratory port and the expiratory connection. The inspiratory valve and the expiratory valve are operable between first configurations that permit flow there though and second configurations that occlude flow through the valves. The inspiratory valve and the expiratory valve are configured to operate in the second configuration when the patient transfer device is disconnected from the at least one host device.

Abstract: A mechanical ventilation system includes at least one processor in communication with a display device and at least one sensor configured to measure an aspect of the air carried by the ventilation system. The at least one processor is configured to receive and process data received from the at least one sensor. The processor is configured to generate and display on the display device a first graph of a measured aspect of the air corresponding to a first time period and a second graph of a measured aspect of the air corresponding to a second time period subsequent to the first time period. The at least one processor is configured to display the second graph superimposed over the first graph.

Abstract: A device for monitoring physiological parameters of a medical patient includes a pneumatic system configured to be coupled to a patient to provide a regulated gas thereto, a computer coupled to the pneumatic system and configured to regulate gas to the patient via the pneumatic system, and a touchscreen monitor coupled to the computer. The touchscreen monitor includes a first graphical user interface (GUI) having a first display, and a second GUI having a second display different from the first display and configured having interaction fields to enable parameters to be input therewith. The device includes a first trigger configured to switch at least from the first GUI to the second GUI.

Abstract: An expiratory flow sensor system is disclosed herein. The expiratory flow sensor includes an expiratory channel adapted to transfer an expiratory gas, a fresh gas channel adapted to transfer a fresh gas, and a sensing element disposed within the fresh gas channel so that the sensing element is never directly exposed to the expiratory gas. The sensing element is configured to measure a fresh gas flow rate. The fresh gas flow rate may be implemented to estimate an expiratory flow rate in a manner that minimizes imprecision attributable to sensing element contamination.
