…of chest compressions. Identifying return of spontaneous circulation (ROSC). Prognostication. Potential reasons for a flat ETCO2 curve include: Ventilator or capnograph not activated. Displacement of…

Cardiac arrest due to pneumothorax

…In instances of tension pneumothorax, the accumulated pressure can shift the entire mediastinum, manifesting externally as a laryngeal displacement. Etiologies of tension pneumothorax include: Traumatic…

Mitral regurgitation

Heart Failure With Preserved Ejection Fraction: Diagnosis and Treatment

…develop through papillary muscle displacement, annular dilatation, or both; progressive ventricular remodeling may also occur in primary valvular disease. Increasing severity of mitral regurgitation is…

Intravascular Imaging: IVUS and OCT for PCI Optimisation
