Abstract
Embodiments disclosed herein are directed to ventilation devices, systems, and methods for applying positive end expiratory pressure (PEEP) to the lungs of a patient. For example, applying above atmospheric pressure to the lungs of the patient may mitigate alveolar collapse in the lungs and/or may have other health benefits for the patient.
Claims23
A system for applying positive end expiratory pressure (PEEP) in ventilation of lungs of a patient, the system comprising:
- an exhalation line configured to be in fluid communication with the lungs of the patient and to receive exhaled gas from the lungs of the patient;
- a diaphragm valve coupled to the exhalation line and configured restrict fluid flow therefrom, thereby applying positive end expiratory pressure during exhalation of air from the lungs of the patient, in response to a control pressure applied at an actuator of the diaphragm valve;
- an actuator line coupling the diaphragm valve to a source of pressurize fluid;
- an electrically-controllable valve coupled to the actuator line and controlling the pressure applied by fluid from the source of pressurized fluid to the actuator of the diaphragm valve;
- and
- a controller operably coupled to the electrically-controllable valve and configured to change the positive end expiratory pressure by directing operation of the electrically-controllable valve.
A system for applying positive end expiratory pressure (PEEP) in ventilation of lungs of a patient, the system comprising:
- an exhalation line configured to be in fluid communication with the lungs of the patient and to receive exhaled gas from the lungs of the patient;
- a pressure-operated valve coupled to the exhalation line and configured restrict fluid flow therefrom, thereby applying positive end expiratory pressure during exhalation of air from the lungs of the patient, in response to a control pressure applied on an actuator of the pressure-operated valve;
- an actuator line coupling the pressure-operated valve control to a source of pressurized breathable gas and configured to supply the pressurized breathable gas to apply the control pressure on the actuator of the pressure-operated valve;
- an inhalation line coupleable to the source of pressurized breathable gas to supply the breathable gas into the lungs of the patient;
- a supply valve coupleable to the source of pressurized breathable gas and coupled to the actuator line and to the inhalation line and configured to control supply of the pressurized breathable gas thereto.
A method for controlling application of positive end expiratory pressure (PEEP) in ventilation of lungs of a patient, the method comprising:
- placing a pressurizable channel in fluid communication with the lungs of the patient for accepting exhaled gas therefrom;
- operating a pressure-controllable valve to control flow of the exhaled gas in the pressurizable channel by applying pressure at an actuator of the pressure-controlled valve;
- and
- controlling a solenoid valve to apply the pressure at the actuator of the pressure-controlled valve.
