What is the difference between central sleep apnea and obstructive sleep apnea? In this lesson, we learn about sleep apnea, its symptoms, diagnosis, treatment, and differentiate between central sleep apnea and obstructive sleep apnea. USMLE
Pneumothorax also known as collapsed lung occurs when air is trapped in the pleural space. Trapped air causes a loss of negative pressure in the pleural cavity, reduces surface tension, and induces the lungs to collapse. There are 3 types of Pneumothorax or collapsed lungs: 1) Spontaneous 2) Traumatic, and 3) Tension Pneumothorax.
In this lesson, we learn the different types of pneumothorax (collapsed lung) and important terminology. USMLE
