What is the medical term for alveolar collapse?

The medical term for alveolar collapse is atelectasis. This condition occurs when the tiny air sacs in the lungs, known as alveoli, become deflated or filled with fluid, disrupting normal gas exchange. Atelectasis can lead to reduced oxygen levels in the bloodstream and can be caused by various factors, including obstruction of the airways, compression of the lung, or post-surgical changes due to anesthesia or immobilization.

Understanding atelectasis is critical, as it can significantly affect respiratory function. The collapsed alveoli can result in reduced lung capacity, leading to complications such as hypoxemia and an increased risk of infections. Recognizing and addressing atelectasis in patients is an essential part of providing effective airway management and respiratory support in a paramedic setting.
