Pron-Position Mattress Ventilation Ventilator COVID-19

The mattress-laying is designed to accommodate the patient in the supine position. There is a place to place a ventilator mask. passages for left and right side connection. the inclination of the supporting mattress and the moderate rigidity of the material reduces patient discomfort. The cover is made of waterproof material. Ventilation of the lungs in the prone position (prone position) Alveolar collapse, edema and atelectasis of the lung areas occur mainly in the underlying sections. Prone position - laying the patient, who is on a ventilator, on the stomach, which ensures the movement of pulmonary blood flow and improves ventilation of those areas of the lungs that remain hypoventilated in the patient's supine position. Ventilation in the prone position leads to: alveolar recruitment; straightening atelectasis without creating increased pressure in the airways; improved oxygenation. Measures to be taken before transferring the patient to the prone position: stop the introduction of food through the nasogastric tube and, if indicated, aspirate the trachea.

Prone position technique. The main indications for the use of the prone position are acute respiratory distress syndrome (ARDS). Given the safety of the method, it is possible to use it for prophylactic purposes. The initial stages of ARDS are more amenable to prone-position therapy than the final stages in combination with fibrosis. In the initial stages of ARDS, the prone position allows you to quickly and significantly increase oxygenation in extrapulmonary etiology of the syndrome. A side effect of the prone position is compression of the ventral portions of the body. Therefore, the use of the prone position is limited in patients with postoperative and other wounds on the anterior surface of the body. Swelling of the face is possible, which usually disappears 2 hours after returning to the supine position. The prone position should be used with caution in patients with elevated intracranial pressure due to its increase when the patient is turned over, which leads to a decrease in cerebral perfusion pressure. An absolute contraindication to performing the prone position is spinal injury. The time spent by the patient in the prone position varies from 8 to 16 hours a day. Patients on mechanical ventilation, as a rule, after turning over on their stomach, continue ventilation in the same mode as before the manipulation. In overweight patients, the effect of prone position is more pronounced than in patients with normal weight.
