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.

A connection assembly for rotateably and electrically coupling an accessory to a main device includes a housing portion, a rotatable port assembly, and a wire assembly. An end of the port assembly is coupled to the accessory. The port assembly includes an electrical connector member having a first connector end electrically coupled to the accessory. The wire assembly has an electrical wire member having a first end electrically coupled to a second connector end of the electrical connector member and a second end electrically coupled to a power supply. The wire member is spooled around the port assembly and encased in a chamber defined between the housing portion and the port assembly. Rotation of the port assembly in opposite directions causes the electrical wire member to spool more and less tightly around the port assembly without causing pinching or tangling of wires.

A method of providing a pressure support therapy to a patient via a PAP device, includes: providing a flow of a breathing gas at a first pressure to an airway of the patient, receiving a first indication from the patient of an adjustment to the first pressure, responsive to receiving the first indication, providing the flow of breathing gas at a second pressure to the airway of the patient.

A method of providing a pressure support therapy to a patient via a PAP device includes: providing a flow of a breathing gas at a comfort pressure for communication to an airway of the patient for a predetermined period of time and adjusting the pressure of the flow of the breathing gas from the comfort pressure to a prescribed pressure, wherein the comfort pressure is greater than the prescribed pressure.

The present invention connects to tubing through which gas flows to a patient. An alert notifies monitoring personnel that oxygen flow to the patient has been interrupted, because the tubing has been disconnected. The invention comprises an adapter that is connected to a gas or oxygen source and a nipple over which the tubing fits and through which oxygen flows to the patient. When the tubing becomes disconnected from the nipple, the oxygen flow actuates an alert. In one embodiment, the invention includes a spring and swing arm that, when the tubing becomes disconnected from the nipple, align the nipple with a swing arm so that the gas flows through the nipple and the swing arm to actuate the alert.

Described here are closed-circuit breathing devices and methods for their use. In general, the closed-circuit breathing device is configured to achieve a steady-state equilibrium, whereby therapeutic gas is introduced into the breathing circuit in small, controlled volumes until a steady state concentration of the therapeutic gas is reached. During this time, the closed-circuit breathing device is operated in a true closed circuit, such that the therapeutic gas is not lost to the atmosphere. Safety measures are built into the closed-circuit breathing device so that a hypoxic mixture is not delivered to the subject. The therapeutic gas may be xenon.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.

Provided is a multi-users cannabis dispenser comprising: a vessel comprising at least two compartments, each compartment configured to contain at least one cannabis composition comprising at least one active component; at least one dispensing unit associated with said at least one compartment, said dispensing unit configured to controllably release from said compartments a metered dose of said composition contained therein; a control unit comprising a data input unit configured to receive data relating to a specific user, data indicating a metered dose of one or more said cannabis compositions to be administered to said specific user and/or to receive data relating to a specific cannabis composition, data indicating a metered dose of said specific composition to be administered to said specific user and configured to control the dispensing unit to release at least one said metered dose. Further provided are methods of use of the multi-users cannabis dispenser.

The invention relates to a respiratory assistance apparatus (1) usable by a first responder, such as a doctor from the emergency ambulance service, a fire fighter, a nurse or the like, when this first responder is performing cardiac massage on an individual (20) in cardiopulmonary arrest, in order to ventilate the said individual while he or she is being subjected to chest compressions. According to the invention, the respiratory assistance apparatus (1) comprises signal processing means designed to supply the display means with a corrected frequency value (F.sub.c) corresponding to the frequency value (F) determined immediately before the start of a time of duration (Dh, Db) considered, when the signal processing means do not detect a chest compression (CC) for part of the said duration (Dh, Db) considered.

The invention relates to a mechanical ventilation system (10) for respiration of a patient (5), the system being adapted for providing decision support for mechanical ventilation. Control means (12) is adapted for using both first data (D1) and second data (D2), indicative of the respiratory feedback in the blood, in physiological models (MOD) descriptive of, at least, lung mechanics, and/or gas exchange in the lungs of the patient, the physiological models comprising a number of model parameters (MOD_P). The control means is further arranged for simulating the effect on one, or more, model parameters (MOD_P) of the physiological models for a suggested value of the positive end expiratory pressure (PEEP) setting for the ventilation means, and thereby provide decision support in relation to said suggested PEEP value. The invention is advantageous for providing mathematical based models of changes in physiology in response to changes in ventilator settings of the PEEP thereby allowing mathematical physiological models to predict changes in clinical variables for a given value of PEEP.
