What should you observe when providing assisted ventilation?

When providing assisted ventilation, observing that the chest should just start to rise with each ventilation is an indication that air is entering the lungs effectively. This means that the airway is open and the ventilation technique is delivering adequate air without excessive pressure.

If the chest were to sink with each ventilation, it would suggest that the proper airflow is not occurring and that the ventilations are not making a positive impact on the patient’s breathing. A flat chest during ventilation indicates either a failure to ventilate or that the airway is obstructed. Conversely, if the chest rises rapidly, it could indicate too much pressure, which can lead to complications such as barotrauma or over-inflation of the lungs. Thus, a gradual rise of the chest is the correct observation to ensure effective and safe assisted ventilation.
