🫁🏋🏻 New Xlung Trainer Exercise | Patient with ARDS on the second day of protective mechanical ventilation: what is the respiratory muscle effort (Pmus)?
By: BETINA SANTOS TOMAZ, FISIOTERAPEUTA - 03/17/2026 16:05
We’ve just released a new clinical case on the Xlung Trainer designed to challenge your ability to detect respiratory muscle effort in ARDS.
💡 Clinical relevance:
Even under deep sedation, patients with ARDS may present unexpected inspiratory effort, which can worsen lung injury if not recognized early.
🧩 Clinical Scenario
A 64-year-old man (1.70 m) is on day 2 of invasive mechanical ventilation due to ARDS secondary to pneumonia.
Despite continuous sedation (RASS -5), he presents:
- Worsening oxygenation (↑ FiO₂ requirement)
- Negative deflections in the airway pressure curve
- Signs of active inspiratory effort and possible asynchrony
🧠 What you will learn
✅ Recognition of inspiratory effort during controlled ventilation
✅ Interpretation of ΔPocc as a surrogate of Pmus
✅ Clinical reasoning in P-SILI prevention
✅ Decision-making in deeply sedated ARDS patients
