Efficacity of Ventilator strategy in A.R.D.S (Acute Respiratory Distress Syndrome).

Abstract

Background: ARDS is defined as pulmonary inflammatory process characterized by increased capillary permeability associated with acute severe hypoxemia and bilateral infiltrates on the chest radiograph. Chlinical manifestations of ARDS is associated with a reduction of functional residual capacity and static compliance of the respiratory system.Recently,after experimental models and physiological studies have just established the principles to understand the potential beneficial effects of PEEP and reduction in mortality to 22%. The benefit of PEEP has been demonstrated in terms of preventing cyclic opening and collapsing alveoli in acute respiratory distress syndrome patients (ARDS). Aim of study: To determine the appropriate PEEP level in-patients with ARDS. Objective: By using optimal PEEP:to realize the maximal alveolar recruitment.To avoid the decrease of oxygen delivery (DO2) as result of an unfavourable reduction in cardiac output. Material and methods:Retrospectiv study of 120 patients which only 63 of them are included in study with age 18-70 years old.(2012-2014 ) The entry criteria were clinically (severe dyspnoea, tachypnea, cyanosis); PaO2/FiO2 220 mmHg survive. The role of PEEP in clinical practice is still debated but, in selected categories of patients with a careful monitoring, it may play an important role in improving outcome.
