Blood filter: removal of microaggregates during blood transfusion; platelet, leucocyte and fibrin aggregates form in stored blood and are thought to produce pulmonary microembolism -> pulmonary dysfunction
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 is diastolic reflux of blood from aorta to LV due to malposition of the aortic cusps. RISK FACTORS age enlarged aortic root diameter: Marfans, Enhlers-Danlos, oesteogenesis imperfecta, connective tissue disorders bicuspid AV atherosclerosis infective endocarditis rheumatic heart disease connective tissue or inflammatory diseases antiphospholipid syndrome trauma ankylosing spondilitis SYMPTOMS SOBOE angina LVF EXAMINATION […]
Contractility = the change in force generated independent of preload. Inotropy and contractility are essential synonymous — inotropes are agents that increase contractility.
Arguments for and against Compression Only CPR
Blood Culture Bottles: tubes for sampling blood for microbiological cultures; detection of circulating microorganisms in bacteraemia and septicaemia
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: a device that acts as a combination between a bag-valve mask and a portable ventilator; primarily for prehospital use
