1. A ventilation assembly for assisting resuscitative treatment of a patient comprising delivery of manual ventilations to the patient by at least one rescuer, the ventilation assembly comprising:
a monitor device comprising a display interface; and
a flow sensor in communication with the monitor device and configured to generate a measurement signal corresponding to at least one flow parameter of a first ventilation breath of the manual ventilations delivered to the patient,
wherein the monitor device is configured to receive the measurement signal generated by the flow sensor and display ventilation feedback on the display interface for guiding the at least one rescuer in performing the manual ventilations to the patient, and
wherein the ventilation feedback comprises a ventilation performance indicator comprising a shape that fills as the ventilation breath of the manual ventilations is delivered to the patient, and the ventilation feedback further comprising a countdown timer provided in anticipation of a second ventilation breath, which is configured to count down an interval time until the second ventilation breath of the manual ventilations should be delivered to the patient.
