Final answer:
The ARDSNET guidelines recommend a conservative PaO2 goal of 55-80 mmHg or an oxygen saturation of 88-95% during mechanical ventilation for patients with ARDS to minimize oxygen toxicity and barotrauma.
Step-by-step explanation:
The PaO2 goal of ARDSNET (Acute Respiratory Distress Syndrome Network) refers to the targeted range of arterial oxygen partial pressure in the management of patients with acute respiratory distress syndrome (ARDS). ARDSNET guidelines suggest a conservative oxygenation goal with a PaO2 of 55-80 mmHg or an oxygen saturation (SpO2) of 88-95% during mechanical ventilation.
This strategy aims to minimize oxygen toxicity and barotrauma by using lower tidal volumes and avoiding high oxygen concentrations unless necessary for life-threatening hypoxemia.
