Why do pulse pressure variations fail to predict the response to fluids in acute respiratory distress syndrome patients ventilated with low tidal volume?
نویسندگان
چکیده
Respiratory-associated variations in stroke volume and pulse pressure are frequently used to predict the response to fluid administration. However, it has been demonstrated that low tidal volume ventilation may limit their use in patients with acute respiratory distress syndrome (ARDS). In this issue, a trial investigates the value of pulse pressure variation to predict fluid responsiveness in a large series of patients with ARDS ventilated according to current guidelines.

BACKGROUND Sensitivity and specificity of respiratory change in pulse pressure (DeltaPP) to predict preload dependency has been questioned at small tidal volumes (VT) in critically ill patients suffering from acute respiratory distress syndrome (ARDS). We studied DeltaPP in pigs with ARDS-like syndrome during reversible hemorrhagic shock. METHODS Prospective, observational animal study in a L...

Acute Respiratory Distress Syndrome (ARDS) is a clinical syndrome consisting of tachypnea, refractory hypoxemia, and diffuse opacities on chest radiographs after infection or trauma which ultimately leads to respiratory failure. The principles of treatment are based on patient care in ICU, mechanical ventilation and medical treatments. By using lower plateau, less tidal volume, higher positive ...

Predicting fluid responsiveness has become a topic of major interest. Measurements of intravascular pressures and volumes often fail to predict the response to fluids, even though very low values are usually associated with a positive response to fluids. Dynamic indices reflecting respiratory-induced variations in stroke volume have been developed; however, these cannot be used in patients with...

BACKGROUND Heart-lung interactions are used to evaluate fluid responsiveness in mechanically ventilated patients, but these indices may be influenced by ventilatory conditions.
