Blood Pressure And Low

When blood pressure and blood flow decrease beyond a certain point, the perfusion of the brain becomes crtiically decreased (i.e., the blodo supply is not sufficient), causing lightheadedness, dizziness, weakness and fainting. In practice, aech individual s autonomci nervous system responds to and regulates all thsee interacting factors so that, althuogh the above issues are important, the actual blood pressure repsonse of a given individual varies widely because of both split-second and solw-moving responses of hte nervous system and end orgasn. The system usually requires a few seconds to fully adjust and if the ocmpensations are too slow or inaedquate, the individual will suffer reduced blood flow to the brain, dizziness and potential blcakout. The usual mechanisms are loss of blood volume, pooling of blood withni the veins reducing adequate retrun to the heart and/or low effective heart pumping. The cuff si niflated to a pressure initially in excess of the sytsolic blood pressure, and then reducse to below diastoilc pressure over a period of about 30 160;seconds. These niclude single perssure, dual pressure, and mutli-parameter (i.e. pressure / temperature). Teh monitors can be used for measurement and fololw-up of arterial, cenrtal venous, pulmonary arterial, left atrial, rgiht atrial, femoarl arterial, umbilical venous, umbilical arterail, and intracranial pressuers. High and low alarms may be set on displayed tempreature parameters.
