New York State Emergency Medical Technician (EMT) Practice Exam

Hemothorax is defined as the accumulation of blood in the pleural space, which is the area between the two layers of pleura that surround the lungs. This condition typically results from trauma, surgical complications, or underlying medical conditions that cause bleeding into the pleura. The presence of blood can lead to respiratory distress and decreased lung capacity, as it occupies space that should be filled with air, thus impairing normal lung function. Understanding hemothorax is crucial for EMTs, as recognizing the signs and symptoms, such as chest pain, shortness of breath, or signs of shock, allows for timely intervention. This can facilitate quicker transport to a hospital and appropriate treatment, which may include drainage of the blood and management of the underlying cause.
