Airway Pressure Release Ventilation (APRV) is a mode of mechanical ventilation that maintains high continuous positive airway pressure (CPAP) with brief, intermittent releases to lower pressure levels, facilitating both oxygenation and ventilation. It is particularly beneficial for patients with acute respiratory distress syndrome (ARDS) as it minimizes alveolar collapse and improves oxygenation without the need for high tidal volumes.

Mechanical ventilation is a critical life-support technique used in intensive care units to assist or replace spontaneous breathing in patients with respiratory failure. It involves the use of a machine, called a ventilator, to deliver air to the lungs at controlled pressures and volumes, ensuring adequate oxygenation and carbon dioxide removal.

Acute respiratory distress syndrome (ARDS) is a severe lung condition characterized by rapid onset of widespread inflammation in the lungs, leading to respiratory failure. It is often caused by trauma, pneumonia, or sepsis, and requires intensive medical care, including mechanical ventilation, for management.

Acute Respiratory Distress Syndrome

ARDS

Alveolar collapse, or atelectasis, occurs when the alveoli in the lungs become deflated or filled with fluid, leading to reduced gas exchange and potentially impaired respiratory function. It can result from various causes, including obstruction, compression, or surfactant deficiency, and requires prompt intervention to restore normal lung function.
