The lung ultrasound: facts or artifacts? In the era of COVID-19 outbreak.

Ultrasound is the most disruptive innovation in intensive care life, above all in this time, with a high diagnostic value when applied appropriately. In recent years, point-of-care lung ultrasound has gained significant popularity as a diagnostic tool in the acutely dyspnoeic patients. In the era of Sars-CoV-2 outbreak, lung ultrasound seems to be strongly adapting to the follow-up for lung involvement of patients with ascertaining infections, till to be used, in our opinion emblematically, as a screening test in suspected patients at the emergency triage or at home medical visit.

Releasing Burn-Induced Compartment Syndrome by Enzymatic Escharotomy-Debridement: A Case Study.

Burn-induced compartment syndrome represents a serious and acute condition in deep circumferential burns of the extremities which, if left untreated, can cause severe complications. The surgical escharotomy that releases the high subdermal pressure is the therapeutic treatment of choice for burn-induced compartment syndrome. Guidelines for escharotomy indications and timing include pressure greater than 30 mm Hg and 6 Ps (Pain, Pallor, Paresthesia, Paralysis, Pulseless, and Poikilothermia).

Non-invasive estimation of cardiac output in mechanically ventilated patients: a prolonged expiration method.

A non-invasive method for the estimation of cardiac output in mechanically ventilated patients is described. The method is based on prolonged expiration, and relies on measurement of gas concentrations and flow rate. A pneumatic system, with an ad hoc designed orifice resistance, has been made and experimentally characterized to adapt the breathing circuit to this application.
