Question

Quizplus · Accepted Answer

Patients receiving mechanical ventilation for respiratory failure should undergo a formal assessment of discontinuation potential if the following criteria are satisfied: 1.Evidence for some reversal of the underlying cause of respiratory failure; 2.Adequate oxygenation (e.g.,PaO₂/FIO₂ >150-200; requiring positive end-expiratory pressure [PEEP] < or = 5-8 cm H₂O; FIO₂ < or = 0.4-0.5)and pH (e.g.,> or = 7.25); 3.Hemodynamic stability as defined by the absence of active myocardial ischemia and the absence of clinically important hypotension (i.e.,a condition requiring no vasopressor therapy or therapy with only low-dose vasopressors such as dopamine or dobutamind<5 micro g/kg/min); and 4.the capability to initiate an inspiratory effort.
