What is the purpose of positive pressure ventilation in flail chest treatment?

To increase oxygen levels
To support breathing
To stabilize the chest wall
To reduce blood pressure

The correct answer is: To support breathing

Positive pressure ventilation plays a crucial role in supporting breathing for patients with a flail chest. In the case of a flail chest, the rib fractures can lead to sections of the chest wall moving paradoxically, meaning that when the patient inhales, those segments may move inward instead of outward. This can significantly impair the patient's ability to effectively ventilate their lungs and achieve adequate oxygenation. By applying positive pressure ventilation, we can ensure that air is delivered to the lungs even when the chest wall is compromised. This method effectively aids in expanding the lungs, promoting better gas exchange, and helping to maintain adequate respiratory function. This support is vital as it alleviates respiratory distress and can be life-saving in cases of severe rib fracture or respiratory failure associated with flail chest. The focus of the treatment is to assist the patient in achieving effective ventilation and reducing the work of breathing, which is essential in the management of this condition.
