What tidal volume setting is recommended for non-injured ARDS lungs?

The recommended tidal volume setting for non-injured ARDS (Acute Respiratory Distress Syndrome) lungs is 6-8 mL/kg of ideal body weight (IBW). This range is important because it strikes a balance between providing adequate ventilation and minimizing the risk of ventilator-induced lung injury (VILI).

Lower tidal volumes help reduce the overdistension of alveoli and prevent further lung damage while still facilitating sufficient gas exchange. This approach is aligned with evidence-based guidelines that demonstrate improved outcomes in ARDS patients when using lower tidal volumes compared to traditional higher-volume settings. By utilizing the 6-8 mL/kg range, clinicians can optimize pulmonary mechanics and improve oxygenation without causing excessive strain on compromised lung tissue.

In contrast, higher tidal volumes can exacerbate lung injury and increase the risk of complications, which is why settings outside of the 6-8 mL/kg range are not recommended for non-injured ARDS lungs.
