Mechanical ventilation is a medical intervention that assists patients with breathing difficulties or respiratory failure by delivering air into their lungs through a machine. It is commonly used in critical care settings such as intensive care units and operating rooms to support patients who are unable to breathe on their own. Mechanical ventilation can be delivered invasively through a tube inserted into the patient's airway or non-invasively through a mask or nasal prongs. The goal of mechanical ventilation is to improve oxygenation and remove carbon dioxide from the body, allowing the patient's lungs to rest and heal. Research in this area focuses on optimizing ventilation strategies, minimizing the risks and complications associated with mechanical ventilation, and improving patient outcomes.
