Egyptian Consensus on the Role of Lung Ultrasonography During the Coronavirus Disease 2019 Pandemic.

Background & Aims: Coronavirus disease 2019 (COVID-19) is a global health problem, presenting with symptoms ranging from mild nonspecific symptoms to serious pneumonia. Early screening techniques are essential in the diagnosis and assessment of disease progression. This consensus was designed to clarify the role of lung ultrasonography versus other imaging modalities in the COVID-19 pandemic.

ΔSpO2/distance ratio from the six-minute walk test in evaluation of patients with chronic obstructive pulmonary disease.

Introduction: The six-minute walk test (6MWT) contains two independent components: walk distance (6MWD) and oxygen saturation (SpO₂). 6MWD does not give detailed data on numerous COPD associated disorders. As oxygen desaturation plays a key role in exercise limita-tions, a few new parameters integrating oxygen desaturation during exercise along with walk distance are necessary.
