In ARDS mechanical TV is
**Core Concept**
The Acute Respiratory Distress Syndrome (ARDS) is a life-threatening medical condition characterized by **hypoxemia** and **pulmonary edema**. In ARDS, mechanical ventilation is crucial for managing the condition. The **tidal volume (TV)** setting is critical in ventilator management.
**Why the Correct Answer is Right**
In ARDS, using lower **tidal volumes (TV)** is recommended to prevent **ventilator-induced lung injury (VILI)**. A **tidal volume** of 6 mL/kg of predicted body weight is typically used. This strategy helps to reduce **stretch injury** to the alveoli and minimize the risk of **barotrauma**.
**Why Each Wrong Option is Incorrect**
**Option A:** Higher tidal volumes can cause lung injury.
**Option B:** Very low tidal volumes may lead to inadequate ventilation.
**Option D:** This option does not align with lung-protective ventilation strategies.
**Clinical Pearl / High-Yield Fact**
In ARDS, lung-protective ventilation with lower tidal volumes is essential to reduce morbidity and mortality.
**Correct Answer:** D. 6 mL/kg
