The purpose of this study is to assess thrombotic risk in CoViD-19/pneumonia patients with acute respiratory failure and to compare populations treated with three different antithrombotic prophylaxis protocols. The primary outcome is to analyze the prevalence of thrombotic events in hospitalized patients, while the secondary outcome is to analyze the correlation between different anticoagulation targets with thrombotic events. All patients referred to our hospital for acute respiratory failure due to COVID-19 pneumonia between 18 and 31 May 2020 were included.

Aim of this paper is to present a combined impedance plethysmography and spectrometry technique suitable to measure the functionality of the peripheral vascular system, with emphasis on the lower limbs. The plethysmographic investigation allows studying the venous flow by detecting the change in blood volume through an electrical bio-impedance measurement. In particular, such measurement is based on a procedure that does not require the use of an occlusive cuff that might cause a detachment of potential thrombus because of the downstream venous pressure.
