A combination positive airway pressure (PAP) or continuous positive airway pressure (CPAP) and resuscitation system and related methods. The systems can be well-suited for use in providing CPAP therapy for a neonate or infant patient, with the ability to also provide resuscitation therapy at a peak inspiratory pressure (PIP) as needed or desired without switching to another system or switching the patient interface. The system can include an expiratory pressure device capable of regulating a positive end expiration pressure (PEEP) of the system, which preferably can also induce pressure oscillations relative to a mean PEEP.

A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

An apparatus for oxygenation and/or CO2 clearance of a patient. The apparatus comprising: a flow source or a connection for a flow source for providing a gas flow, a gas flow modulator, a controller to control the gas flow. The controller is operable to: receive input relating to heart activity and/or trachea gas flow of the patient, and control the gas flow modulator to provide a varying gas flow with at least two oscillating components. One oscillating component has a frequency based on the heart activity and/or trachea flow of the patient. One oscillating component has a frequency to: promote bulk gas flow movement, or promote mixing.

A tracheal tube (e.g., an endotracheal tube) includes an inserting cannula (that may be able to swivel), and wherein the inserting cannula is connected to an elbow adaptor through a Bayonet Neill-Concelman (BNC) connection. The BNC connection may provide more secure connection of the corresponding components and may be able to withstand greater amounts of force exerted on them without becoming detached from each other. The elbow adapter may further be coupled to a pressure release valve that will alleviate pressure buildup within the tracheal tube.

A respirator mask includes a facepiece configured to create a seal with a face of a user and a mask frame coupled with the facepiece. A port assembly is coupled with the mask frame and an inhalation path including a filter, a first valve seat and a first valve member, the filter and first valve member coupled with the first valve seat on opposed sides. An exhalation path includes a second valve seat and a second valve member, the second valve member surrounding the first valve seat.

A patient ventilator system includes a patient delivery circuit having an inspiratory section that delivers an inspiratory gas flow to a patient and an expiratory section that receives expiratory gas flow from the patient, wherein a bidirectional blower motor drives the inspiratory gas flow in the inspiratory section and controls the expiratory gas flow in the expiratory section. A flow sensor measures gas flow rate between the bidirectional blower motor and the patient delivery circuit. A four quadrant controller is configured to control speed and direction of the bi-directional blower motor based on the measured flow rate so as to effectuate ventilation for the patient.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The flow outlet airline is configured to be connected to an invasive ventilator circuit or a noninvasive ventilator circuit. The breath detection airline includes airline inlet. The airline inlet is separated from the airline outlet of the flow outlet airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.

The present disclosure provides a flow interruption valve comprising a first section permanently connected to the second section. The first section has a patient portion to connect to a corresponding tube of a patient, whereas the second section has a ventilator port to connect to a corresponding tube of a ventilator. The first section is further comprised of a compression system, which can be compressed to pinch an inner tube and prevent airflow from the ventilator to the patient and vice-versa.

A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise a pressure relief valve that opens when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.

A respiratory device provides respiratory support to a patient. The respiratory device includes an expandable bag and a rigid valve housing. The expandable bag has an air inlet valve as well as a first and second sides that are bounded, respectively, by first and second rigid side panels. Each of the first and second rigid side panels includes a biasing member projection. The rigid valve housing is in fluid communication with the expandable bag. The rigid valve housing includes an adjustable tidal volume control device that interfaces with the biasing member projection of each of the first and second rigid side panels to set one of a plurality of predetermined tidal volumes for the expandable bag in an uncompressed or compressed configuration. The rigid valve housing additionally includes a patient breathing interface connection member.
