Arterial lines are most commonly used in intensive care medicine and anesthesia to monitor blood pressure directly and in real-time (rather than by intermittent and indirect measurement) and to obtain samples for arterial blood gas analysis.
Invasive vascular pressure monitors are pressure monitoring systems designed to acquire pressure information for display and processing. There are a variety of invasive vascular pressure monitors for trauma, critical care, and operating room applications. These include single pressure, dual pressure, and multi-parameter (i.e. pressure ...
Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Osler's sign (or Osler sign) of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed. [1]
A simple view of the hemodynamics of systemic arterial pressure is based around mean arterial pressure (MAP) and pulse pressure. Most influences on blood pressure can be understood in terms of their effect on cardiac output, [77] systemic vascular resistance, or arterial stiffness (the inverse of arterial compliance). Cardiac output is the ...
Pressure gauge used to measure intracompartmental pressure in suspected compartment syndrome. The device consists of a needle catheter that is inserted directly into the affected limb which is then connected to a pressure transducer. The transducer can relay the measurement to an A-line monitor or a standard pressure gauge.
The goal blood pressure for these patients is a mean arterial pressure of 40-50 mmHg or systolic blood pressure of less than or equal to 80. This goes along with certain clinical criteria.
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
Ambulatory blood pressure monitoring allows blood pressure to be intermittently monitored during sleep and is useful to determine whether the patient is a "dipper" or "non-dipper"—that is to say, whether or not blood pressure falls at night compared to daytime values. A nighttime fall is normal and desirable.
