What does PEEP stand for in the context of respiratory support?

1. Positive End Expiratory Pressure

2. Pressure Enhancing Expiratory Effort

3. Positive Expiratory End Pressure

4. Peak End Expiratory Pressure

The correct answer is: Positive End Expiratory Pressure

PEEP, which stands for Positive End Expiratory Pressure, is a crucial concept in respiratory support, particularly in mechanical ventilation and the management of patients with respiratory distress. PEEP involves maintaining a certain level of pressure in the airways at the end of expiration, which helps to prevent the collapse of the alveoli (the tiny air sacs in the lungs). This technique improves oxygenation by increasing functional residual capacity (FRC) and recruiting collapsed alveoli, allowing for better gas exchange. PEEP can also help reduce the work of breathing and improve lung compliance. It is widely utilized in various settings, particularly in neonatal and pediatric care, where infants may be susceptible to respiratory complications. In contrast, the other options do not correctly represent the established terminology related to respiratory support. They either misstate the technical terms or introduce concepts that are not recognized within clinical practice. Understanding PEEP and its implications is essential for effective respiratory management in both neonatal and adult patients.
