COPD can mimic the appearance of pneumothorax on thoracic ultrasound.

abstract：BACKGROUND:Patients with malignant pleural effusion (MPE) have limited prognoses. They require long-lasting symptom relief with minimal hospitalization. Indwelling pleural catheters (IPCs) and talc pleurodesis are approved treatments for MPE. Establishing the implications of IPC and talc pleurodesis on subsequent hospi...

abstract：:Inadequate tissue oxygenation may occur in critically ill patients with sepsis despite an apparently adequate O2 transport (QO2), and this may contribute to the development of an O2 debt and also to multiple organ failure. It has been shown that increasing QO2 by infusing a vasodilator may reveal this O2 debt in septi...
