🫁🏋🏻 New Exercise Available on Xlung Trainer – A Patient with Sudden Hypotension, Tachycardia, and Respiratory Deterioration in the Immediate Postoperative Period

You will analyze a scenario that is extremely common in ICU practice but still leads to many misinterpretations.

🧩 Scenario

A 77-year-old male, a former smoker, was admitted intubated after extensive orthopedic surgery on the left hip. Past medical history: controlled hypertension. Height: 1.70 m.

The patient is still sedated, RASS -5, and developed sudden hypotension (BP: 85 × 45 mmHg) and worsening SpO₂ a few minutes ago.

FiO₂ was increased from 30% to 60%.

🎯 Your mission

  1. Activate the mainstream capnograph.
  2. Analyze the capnogram waveform and PetCO₂ values.
  3. Consider obtaining an arterial blood gas to better interpret the clinical situation.
  4. Answer the questions.

🧠 What this exercise explores

Recognition of typical capnography and capnometry patterns in a severe and potentially life-threatening scenario.

Interpretation of the findings based on physiopathology and critical analysis of the P(a–et)CO₂ gradient in the clinical contexto.

💡 Excellent training for:

• Applied respiratory physiology
• Ventilatory monitoring with capnography
• Exams / residency training / ICU practice
