Top 10 Commonly Confused Words in Respiratory Therapy

Top 10 Commonly Confused Words in Respiratory Therapy 1. Atelectasis vs. Pneumothorax Atelectasis and pneumothorax are two terms that often cause confusion. Atelectasis refers to the collapse of a lung or a part of it, usually due to blockage or pressure. On the other hand, pneumothorax is the presence of air or gas in the pleural cavity, leading to lung collapse. While both involve lung collapse, the causes and mechanisms are different. Atelectasis is often a result of obstruction, whereas pneumothorax can occur due to trauma or underlying lung conditions. 2. Hypoxemia vs. Hypoxia Hypoxemia and hypoxia are terms related to inadequate oxygen levels. Hypoxemia specifically refers to low oxygen levels in the blood, which can be measured using arterial blood gas analysis. Hypoxia, on the other hand, is a broader term, encompassing low oxygen levels in tissues or organs. It can be caused by various factors, including reduced blood flow or impaired oxygen-carrying capacity. While hypoxemia is a measurable value, hypoxia is a clinical condition. 3.
