Features
Read full description

iElastance estimates left ventricular end-systolic elastance (Ees), effective arterial elastance (Ea) and their ratio, ventricular–arterial coupling (VAC), from six values you already have at the bedside: cuff pressures, a standard echocardiogram and two systolic time intervals. No catheter, no extra equipment. FREE • Single-beat calculator (Chen et al., J Am Coll Cardiol 2001): systolic and diastolic pressure, ejection fraction, stroke volume, pre-ejection and total ejection time. • Results update as you type, with checks on impossible values. • "How to measure" guide with diagrams of the method of disks and of systolic times on the LVOT pulsed Doppler. IELASTANCE PREMIUM • Pressure–volume diagram: ESPVR and Ea lines, stroke volume, ESP, EDV, ESV and V0. • Cases: keep your 10 most recent cases, each with as many measurements as you need (baseline, after fluids, after a vasopressor or inotrope…). • Trends of VAC, Ea and Ees over time. • PDF report with results, diagrams, measurement table, trends, method and reference, ready to print or share. • Archive export and import to move your cases to another device.

About

iBronch

Features
Read full description

Bronchoscopy is a procedure in which physicians are able to visualize the trachea and the bronchi that supply ventilation to the lungs. This is usually done under some form of anesthesia or sedation, and there is a learning curve in taking on this common operation. Bronchoscopy requires skill and patience to obtain the views needed for a complete study. iBronch uses images from an actual bronchoscopy to show the user typical views of a normal trachea-bronchial tree. Because its a simulation and does not involve a real patient, it can be used to familiarize oneself on the expected images seen on real patients.
