What is the negative pressure value of the suction device?
Feb 23, 2019
The negative pressure value of the suction device is that suction is an important measure to clean the secretions in the respiratory tract and maintain the smoothness of the respiratory tract. The secretions retained in the respiratory tract of the patient are sucked out by a suitable method of vacuum suction. Generally, the negative pressure of adults is 40-53.3KPa, and the child should be less than 40KPa. . Sucking plays an important role in maintaining airway patency, improving ventilation, and preventing infection. Clinically, some patients with more secretions after tracheotomy have pulmonary atelectasis after repeated vacuum suction.
Reasonable sucking method can ensure the timely inhalation of sputum, avoiding complications such as cough, aspiration, suffocation caused by sputum sucking out, to reduce the chance of respiratory infection and damage to respiratory mucosa. Strict, effective and meticulous airway management is often one of the key factors in the success of disease rescue.
