Tilt Table Test - Preparations

Preparations

Before taking the test, the patient may be instructed to fast for a period before the test will take place and to stop taking any medications. On the day of the tilt table test, an intravenous line may be placed in case the patient needs to be given medications quickly; however, this may influence the results of the test and may only be indicated in particular circumstances. More recently, most investigators monitor cerebral perfusion using mean flow velocity recording with transcranial Doppler ultrasound in supine horizontal position, during and after head-up tilt. An 18 MHz ultrasound transducer is placed on the temporal bone above the cheekbone, using headgear to hold the probe in place.

Famous quotes containing the word preparations:

    At the ramparts on the cliff near the old Parliament House I counted twenty-four thirty-two-pounders in a row, pointed over the harbor, with their balls piled pyramid-wise between them,—there are said to be in all about one hundred and eighty guns mounted at Quebec,—all which were faithfully kept dusted by officials, in accordance with the motto, “In time of peace prepare for war”; but I saw no preparations for peace: she was plainly an uninvited guest.
    Henry David Thoreau (1817–1862)

    In all the important preparations of the mind she was complete; being prepared for matrimony by an hatred of home, restraint, and tranquillity; by the misery of disappointed affection, and contempt of the man she was to marry. The rest might wait. The preparations of new carriages and furniture might wait for London and the spring, when her own taste could have fairer play.
    Jane Austen (1775–1817)

    The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.
    Marcus Tullius Cicero (106–43 B.C.)
