2020年4月24日 · Arterial blood pressure measurement with a pressure transducer and a zero line. The free end of the zero line is attached to the body at the level of the vessel of interest. Before the start of the measurement, a zeroing maneuver is needed to account for the difference in height (i.e., hydrostatic pressure) between the free end of the zero line ...

2014年11月30日 · Introduction Critically ill patients and patients undergoing high-risk and major surgery, are instrumented with intra-arterial catheters and invasive blood pressure is considered the “gold standard” for arterial pressure monitoring. Nonetheless, artifacts due to inappropriate dynamic response of the fluid-filled monitoring systems may lead to clinically relevant …

2015年12月1日 · The exact position of the transducer is relatively easy to be ignored for invasive arterial blood pressure monitoring [3,4]. Improper position of the transducer may cause inaccurate value and shape of the arterial blood pressure wave, which would result in an invalid PiCCO (Pulsion Medical Systems AG, Munich, Germany) algorithm for pulse ...

2006年4月19日 · Introduction Blood pressure measurements frequently guide management in critical care. Direct readings, commonly from a major artery, are considered to be the gold standard. Because arterial cannulation is associated with risks, alternative noninvasive blood pressure (NIBP) measurements are routinely used. However, the accuracy of NIBP …

2012年3月20日 · We performed the fast flush test 130 times; an inadequate dynamic response of the transducer-tubing system was observed 55 times: in 45 cases the arterial signal was underdumped and in 10 cases was overdumped. The arterial dumping was correctly detected by the medical staff in 95% of cases, by nursing staff and postgraduates in 35% of cases.

2006年5月24日 · Introduction Which particular arterial catheter site is associated with a higher risk of infection remains controversial. The Centers for Disease Control and Prevention guidelines of 1996 and the latest guidelines of 2002 make no recommendation about which site or sites minimize the risk of catheter-related infection. The objective of the present study was to …

2006年3月21日 · The location of the arterial transducer will influence the measured MAP and hence the CPP (CPP = MAP - ICP). This survey was conducted to establish current practice in measuring MAP, and to ascertain when nursing a patient at 30° whether the arterial transducer was referenced to the level of the external auditory meatus or the left atrium.

2016年6月8日 · The intra-arterial catheter (24 G (5/8 in), 22 G (1 in), or 20 G (1-1/4 in)) was connected to a straight connector (ICU Medical Smallbore Extension Set with MicroClave R clear; 7 in, 0.24 ml; San Clemente, CA, USA), a stopcock (Hi-Flo™ Smiths Medical, Brisbane, Australia), and high pressure tubing with disposable transducer (Edwards ...

2005年3月7日 · The mercury sphygmomanometer was the most accurate when compared with the arterial line. Both automated devices had unacceptable ranges in the intensive care setting with both algorithms markedly overestimating at low blood pressures. Of the 29 waveforms analysed, 62% of the arterial waveforms had inadequate dynamic responses.
