Emergent Valve Disorders
Emergent Valve Disorders: regurgitation most common; acute or acute on chronic valve dysfunction; acute on chronic often precipitated by increase in metabolic or haemodynamic requirements (sepsis, bleeding, pregnancy).
Aortic Regurgitation
Aortic regurgitation is diastolic reflux of blood from aorta to LV due to malposition of the aortic cusps.
Contractility
Contractility = the change in force generated independent of preload. Inotropy and contractility are essential synonymous — inotropes are agents that increase contractility.
Compression Only CPR
Arguments for and against Compression Only CPR
Blood Culture Bottles
Blood Culture Bottles: tubes for sampling blood for microbiological cultures; detection of circulating microorganisms in bacteraemia and septicaemia
Bite block
Bite block: Prevent damage a patient from biting down when placing an device in or through the oral cavity, or during an intraoral procedure
Oxylator
Oxylator: a device that acts as a combination between a bag-valve mask and a portable ventilator; primarily for prehospital use
ENK Oxygen Flow Delivery System
The ENK oxygen flow delivery system is used in conjunction with emergency cannula cricothyroidotomy
Circulation Assessment
Basic summary of Circulation Assessment
Cement implantation syndrome
Cement implantation syndrome: embolism of fat, bone, marrow, clot, blood and methylmethacrylate; potentially leading to cardiovascular collapse
Cardioversion in ICU
Cardioversion in ICU: cardioversion is the delivery of electrical energy that is synchronised with the QRS complex in an attempt to revert an abnormal rhythm
