In this study, the effect of the recruitment maneuver on intracranial pressure will be examined by measuring the optic nerve diameter with ultrasound before and after the recruitment maneuver.


Respiratory failure is the most important reason for admission to the intensive care unit. Many causes can result in respiratory failure, including trauma, severe burns, sepsis, pancreatitis, and pneumonia. In intensive care patients, mechanical ventilation has become an inevitable practice to ensure adequate oxygenation. However, mechanical ventilation applications can also cause lung damage. Mechanical ventilation is also widely used for a variety of standard surgical procedures. After surgery; A decrease in functional residual capacity (FRC), atelectasis and even lung damage can be seen due to reasons such as anesthesia applications, pain, and surgical procedures.

Recruitment maneuver refers to the dynamic process of reopening unstable atelectasis alveoli by voluntarily providing a temporary increase in transpulmonary pressure.

Although the recruitment maneuver improves oxygenation and reduces mortality, especially in ARDS patients, adverse side effects, although rare, can be seen. The most important of these are the risk of barotrauma after positive pressure applications, increased intrathoracic pressure, hemodynamic instability and increased intracranial pressure after venous return disorder.

In this study, the effect of recruitment maneuver on intracranial pressure will be determined by measuring optic nerve diameter by ultrasound before and after recruitment maneuver in participants followed under mechanical ventilation and with impaired oxygenation.
