a breath detection airline with bidirectional airflow during an assisted breath configured to measure breathing from the user, the breath detection airline comprising an airline inlet, wherein the airline inlet is fluidly separated from the airline outlet of the flow outlet airline, wherein 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; and

a controller in electronic communication with the pressure sensor, wherein the controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor; and

wherein the ventilator is triggered as a function of a waveform generated from sensor data measured at the pressure sensor on a breath-by-breath basis; and

a noninvasive ventilator circuit fluidically connected to the flow outlet airline of the ventilator, wherein the noninvasive ventilator circuit comprises:

a breathing tubing connected to the breath detection airline; and

an oxygen tubing connected to the flow outlet airline;

wherein the breathing tubing is in direct fluid communication with the oxygen tubing.
