A coated or white tongue occurs when the surface is colonised by bacteria or fungi, and dead cells become trapped between the small nodules on the tongue. A coated tongue isn't a disease and isn't usually a sign of anything serious. It's usually only temporary.
Risk factors for treatment failure in patients with severe acute cardiogenic pulmonary oedema. Cardiogenic shock is a state of inadequate bloodflow to the body's tissue caused by the failure of the heart to pump effectively, most commonly following acute myocardial infarction (heart attack).
Unsynchronized cardioversion (defibrillation) is a HIGH ENERGY shock which is delivered as soon as the shock button is pushed on a defibrillator. This means that the shock may fall randomly anywhere within the cardiac cycle (QRS complex). Unsynchronized cardioversion (defibrillation) is used when there is no coordinated intrinsic electrical activity in the heart (pulseless VT/VF) or the defibrillator fails to synchronize in an unstable patient.
