What condition might indicate improper bag-valve-mask ventilation technique?

Improper bag-valve-mask ventilation technique can lead to a pneumothorax, which is a condition where air enters the pleural space and can cause the lung to collapse. When a bag-valve-mask is used incorrectly—such as delivering excessive pressure or improper seal—the air may escape into the thoracic cavity instead of the lungs. This can increase intrathoracic pressure and subsequently interfere with normal respiratory and circulatory functions.

Pneumothorax as a result of improper ventilation indicates that the technique may be too forceful or not adequately controlled, leading to complications that significantly impact the patient’s condition. Recognizing this is critical as it allows healthcare providers to adjust their technique and minimize the risk of further complications during resuscitation efforts.
