Emergency Medical Technician (EMT) Intermediate Practice Exam

What is a common indication for the use of CPAP in patients?

1. Bradycardia

2. Respiratory distress

3. Unconsciousness

4. Coronary artery disease

The correct answer is: Respiratory distress

The use of Continuous Positive Airway Pressure (CPAP) is commonly indicated in patients experiencing respiratory distress. CPAP helps maintain open airways and improves oxygenation by delivering a constant stream of pressurized air, which prevents alveolar collapse and enhances lung expansion. This is particularly beneficial for conditions such as congestive heart failure or chronic obstructive pulmonary disease (COPD), where patients often exhibit difficulty breathing due to fluid in the lungs or airway obstruction. Bradycardia, unconsciousness, and coronary artery disease are not primary indications for CPAP. While these conditions may coexist with respiratory issues, they do not directly warrant CPAP use. Instead, the primary goal of CPAP is to assist patients who are in respiratory distress and require augmented oxygen delivery and airway support.
