Abstract:
The arteriovenous extracorporeal membrane is used in patients with hemodynamic and respiratory failure, unresponsive to conventional treatment. It provides transitory hemodynamic support, oxygenation and removal of CO2, allowing pulmonary rest. Moreover it offers the possibility of ultraprotective ventilation and avoids generation of VILI (Ventilation-Induced Lung Injury). It is not frequently used in patients with hemodynamic failure secondary to obstructive shock due to mediastinal compromise. We present the case of a patient with obstructive shock, mediastinal mass of lymphoproliferative origin that was treated with extracorporeal arteriovenous circulation membrane.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
