Abstract:
1. A ventilator apparatus comprising: a portable housing; a pneumatic assembly disposed in the portable housing, the pneumatic assembly being configured to output gas to be delivered to a patient's air passage; a controller disposed in the portable housing and in communication with the pneumatic assembly, the controller being configured to determine breathing parameter data and operate the pneumatic assembly to output gas to the patient's air passage according to the determined breathing parameter data; at least one operator control disposed on the housing, the at least one operator control comprising a patient parameter input control configured to be manipulated to input at least one patient parameter to the controller; and a barometric pressure sensor disposed in or on the portable housing, the barometric pressure sensor being configured to monitor ambient barometric pressure and to communicate the monitored ambient barometric pressure to the controller, wherein the at least one patient parameter input to the controller comprises a patient size characteristic, wherein the controller is configured to determine the breathing parameter data based on the patient size characteristic input to the controller and to adjust the breathing parameter data based on the monitored ambient barometric pressure.
