1. Lung Ultrasound Indications and Pre-Exam Preparation

The Lung Ultrasound Indications

Lung ultrasound can be used when you are assessing for:

  • Shortness of breath
  • Pneumonia or other recurring infections
  • Cardiogenic pulmonary edema
  • Acute Respiratory Distress Syndrome (ARDS)
  • COPD/Asthma
  • Pneumothorax

The major limitations of lung ultrasound are:

  • Subcutaneous emphysema: ultrasound waves can’t pass through the air in the skin to evaluate the lungs
  • Patient body habitus: may be difficult to see the lung in severely obese patients.
