1. A medical system for assisting a rescuer with an intubation procedure with an endotracheal (ET) tube for a patient, the system comprising:
one or more airflow sensors configured to obtain data indicative of airflow in the patient's airway and data indicative of inspiratory tidal volume and expiratory tidal volume;
one or more physiological sensors to obtain configured to obtain physiological information regarding airflow in the patient's lungs; and
a patient monitoring device communicatively coupled to the one or more airflow sensors, the patient monitoring device comprising:
a user interface comprising a display; and
at least one processor and memory configured to:
receive the data indicative of airflow in the patient's airway and the physiological information regarding airflow in the patient's lungs,
determine presence of airflow in the patient's airway based on the data indicative of airflow,
analyze the physiological information regarding airflow in the patient's lungs to provide an indication of ET tube placement,
determine that a leak may be present in relation to the ET tube based on an analysis of the expiratory tidal volume relative to the inspiratory tidal volume,
based on the indication of ET tube placement and the determination that the leak may be present in relation to the ET tube, output to the display of the user interface an alert to check the ET tube in relation to the leak that may be present.
