Abstract: A system for use in the ventilation of a patient, particularly for a patient using a breathing circuit that is connected along with one or more other breathing circuits to a shared ventilator. The system employs a flow control valve on an inspire air line of an individual breathing circuit for that patient, and measures the tidal volume and pressure in the breathing circuit. A controller is provided with a user interface allowing a desired target volumetric measurement to be input. In response, a control signal is calculated and output to the valve causing the air supply on the inspire line to be adjusted until the measured tidal volume matches the desired volume within a given tolerance. In this way, patient safety is improved for a shared ventilator, by tailoring the ventilation on an individual breathing circuit using a single input value.

Abstract: Apparatus, systems and methods are described, such as for providing, or controlling mechanical ventilation provided to, a patient. A controller may control a gas delivery system to deliver gas to the patient according to a FiO2 setting and a PEEP setting. The controller may adjust the FiO2 setting to an updated FiO2 setting based at least in part on a determined oxygen concentration of the patient's blood and may update the PEEP setting based at least in part on the updated FiO2 setting. Furthermore, the controller may update the PEEP setting based at least in part on the updated FiO2 setting and the current PEEP setting. An updated PEEP setting may be based at least in part on PEEP change eligibility rules and PEEP selection rules. The FiO2 setting may be adjusted so as to relatively rapidly increase the FiO2 setting in response to a rapidly decreasing patient SpO2.

Abstract: A method of, or system for, ventilating lungs in breathing and non-breathing patients--including applications for anesthesia--may comprise maintaining an inspiratory flow rate at an inspiratory setpoint at a low flow setting. Lung pressure in a patient may be regulated between a high pressure setpoint and a low pressure setpoint with periodic expiratory flows and continuous inspiratory flow. An expiratory control valve may be adjusted to an open position when a lung pressure is at or above a high pressure setpoint. An expiratory control valve may be adjusted to a closed position when a lung pressure is at or below a low pressure setpoint. Concurrent venting outflow and CO2 offloading through flow within the lungs may be facilitated by providing an intermittent expiratory flow to the patient while providing the continuous inspiratory flow.
