Using lung ultrasound to diagnose pneumothorax

0

Lung ultrasound can be used to diagnose pneumothorax at the bedside [3] and has a higher sensitivity for detection of pneumothorax in comparison to chest radiograph, which has traditionally been used to diagnose pneumothorax [4-6]” Markota et al (2016).

Abstract:

Pneumothorax is a complication occurring in 4–15% of patients who require mechanical ventilation in the intensive care unit (ICU) and in 1.5–3.1% of patients after central venous catheter insertion [1,2]. Lung ultrasound can be used to diagnose pneumothorax at the bedside [3] and has a higher sensitivity for detection of pneumothorax in comparison to chest radiograph, which has traditionally been used to diagnose pneumothorax [4-6]. Sonographic signs of pneumothorax are absence of lung sliding (LS), absence of B lines, absence of lung pulse and presence of lung point [3].
