A ventilator, including an enclosure; a tubing configured to receive an input gas; a flow outlet airline in fluid communication with the tubing, wherein the flow outlet airline includes an airline outlet, and the flow outlet airline is configured to supply an output gas to a user via the airline outlet; a breath detection airline including an airline inlet, wherein the airline inlet is separated from the airline outlet of the flow outlet airline, and the breath detection airline is configured to receive breathing gas from the user during exhalation by the user via the airline inlet; a pressure sensor in direct fluid communication with the breath detection airline, wherein the pressure sensor is configured to measure breathing pressure from the user, and the pressure sensor is configured to generate sensor data indicative of breathing by the user.

A ventilator includes an enclosure, a tubing configured to receive an input gas, and a flow outlet airline in fluid communication with the tubing. The flow outlet airline includes an airline outlet. The ventilator further includes a breath detection airline including an airline inlet. The airline inlet is separated from the airline outlet of the flow outline airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The ventilator includes a controller in electronic communication with the pressure sensor and an internal oxygen concentrator in fluid communication with the tubing. The internal oxygen concentrator is entirely disposed inside the enclosure.
