What type of ventilation does CPAP provide?

  1. Only during expiration

  2. Only during inspiration

  3. Constant during both inspiration and expiration

  4. Intermittently during the breathing cycle

The correct answer is: Constant during both inspiration and expiration

CPAP, which stands for Continuous Positive Airway Pressure, provides a constant level of pressure throughout both the inspiration and expiration phases of the breathing cycle. This continuous pressure helps to keep the airways open, preventing collapse and ensuring that the air can flow freely into the lungs. This mechanism is especially useful in conditions such as obstructive sleep apnea, where the airway can become obstructed during sleep. The constant pressure delivered by CPAP devices ensures that the airways remain patent at all times, effectively promoting better oxygenation and reducing the effort required for breathing. In contrast, the other options suggest limited pressure application during specific parts of the breathing cycle, which does not align with the fundamental principle of CPAP therapy. Therefore, the correct answer reflects the continuous nature of the pressure provided by CPAP during both phases of the breathing cycle.
