What is the ideal tidal volume (VT) range recommended in the ARDS net protocol?

The ideal tidal volume (VT) range recommended in the ARDSnet protocol is 4-6 ml/kg. This protocol is designed for patients with Acute Respiratory Distress Syndrome (ARDS), where lung protection strategies are essential to minimize ventilator-induced lung injury.

Using a tidal volume within this range helps reduce the risk of over-distention of the alveoli, which can exacerbate lung injury and worsen gas exchange. This conservative approach to ventilator settings has been shown to improve outcomes in ARDS patients compared to traditional higher tidal volume strategies.

Choosing a tidal volume of 4-6 ml/kg allows for sufficient ventilation while also promoting protective lung mechanics, aiding in better overall patient management during mechanical ventilation. This careful balance is crucial in treating ARDS, emphasizing the importance of adherence to evidence-based protocols.
