Title
(EN) LUNG VENTILATOR SYSTEM AND METHOD OF VENTILATING LUNGS IN BREATHING AND NON-BREATHING PATIENTS
(FR) SYSTÈME DE VENTILATION DE POUMON ET PROCÉDÉ DE VENTILATION DES POUMONS CHEZ DES PATIENTS QUI RESPIRENT ET QUI NE RESPIRENT PAS
Abstract
(EN) 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.
(FR) La présente invention concerne un procédé, ou un système, de ventilation des poumons chez des patients qui respirent et qui ne respirent pas (comprenant des applications pour l’anesthésie) pouvant comprendre le maintien d’un débit d’inspiration à un point de consigne d’inspiration à un réglage de flux faible. La pression pulmonaire chez un patient peut être régulée entre un point de consigne à haute pression et un point de consigne à basse pression avec des flux d’expiration périodiques et un flux d’inspiration continu. Une vanne de commande d’expiration peut être réglée sur une position ouverte lorsqu’une pression pulmonaire se trouve au niveau, ou au-dessus d’un point de consigne à haute pression. Une vanne de commande d’expiration peut être réglée sur une position fermée lorsqu’une pression pulmonaire se trouve au niveau, ou en-dessous d’un point de consigne à basse pression. Le flux de sortie de ventilation et le flux traversant d’évacuation de CO2 concomitants à l’intérieur des poumons peuvent être facilités par la fourniture d'un flux d’expiration intermittent au patient en même temps que la fourniture d'un flux d’inspiration continu.
