Methods and systems for increasing oxygen concentration. An example system includes an oxygen valve configured to be coupled to an oxygen source, an oxygen plenum coupled to the valve, and a mixing valve. The mixing valve includes an oxygen inlet coupled to the oxygen plenum, an ambient-air inlet, and an outlet configured to be attached to an inlet of a blower of a ventilator. The system also includes a pressure sensor, coupled to the oxygen plenum, and a control device communicatively coupled to the pressure sensor and the oxygen valve. The control device receives a differential pressure, measured by the pressure sensor, and based on the measured differential pressure, generates a control signal to control the oxygen valve to maintain a target pressure of gas within the oxygen plenum.

A system of treating atelectasis is provided that includes a tracheal tube positioned within an airway of a ventilated patient and an acoustic sensor coupled to the tracheal tube. The system also includes a monitor communicatively coupled to the acoustic sensor. The monitor includes a processor configured to receive a baseline signal from the acoustic sensor. The processor is configured to provide control instructions to adjust a pressure of a gas mixture delivered to the airway through the tracheal tube. The processor is also configured to receive an updated signal from the acoustic sensor after the adjustment and identify a change in airway openness of lungs of the ventilated patient caused by the adjustment of the pressure. Further, identifying the change is based on the baseline signal and the updated signal.

An emergency ventilation system ventilates a patient and includes a chamber housing defining a breathing chamber; a piston; and a motor operably connected to the piston. The motor applies an exhalation force to move the piston in an exhalation direction applies an inhalation force to move the piston in an inhalation direction. The piston increases air in the breathing chamber as the exhalation force is applied and decreases air in the breathing chamber as the inhalation force is applied. An exhalation check valve allows airflow from the air source to the breathing chamber and not to allow airflow from the breathing chamber to the air source as the inhalation force is applied. An inhalation check valve allows airflow from the breathing chamber to the air output and not to allow airflow from the air output to the breathing chamber as the exhalation force is applied.
