2020年4月24日 · Arterial blood pressure (BP) is a fundamental cardiovascular variable, is routinely measured in perioperative and intensive care medicine, and has a significant impact on patient management. The clinical reference method for BP monitoring in high-risk surgical patients and critically ill patients is continuous invasive BP measurement using an arterial catheter. A …

2005年10月26日 · In critically ill patients monitored with an arterial catheter, the arterial pressure signal provides two types of information that may help the clinician to interpret haemodynamic status better: the mean values of systolic, diastolic, mean and pulse pressures; and the magnitude of the respiratory variation in arterial pressure in patients undergoing mechanical ventilation. In …

2014年11月30日 · When an arterial line is put in place, this fact should certainly be taken into consideration. Equally, eventual fibrin deposition may, with time, increase β. Lambermont et al . developed, in an experimental setting, a mathematical transfer function that, by adjusting the natural frequency and the damping coefficient of the fluid-filled ...

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 …

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.

2016年6月8日 · Background The accuracy of arterial lines (AL) using the flush test or stopcock test has not been described in children, nor has the difference between invasive arterial blood pressure (IABP) versus non-invasive cuff (NIBP) blood pressure. Methods After ethics approval and consent, we performed the flush test and stopcock test on AL (to determine over damping, …

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8日 · Introduction Invasive arterial blood pressure monitoring is a common practice in intensive care units (ICUs). Accuracy of invasive blood pressure monitoring is crucial in evaluating the cardiocirculatory system and adjusting drug therapy for hemodynamic support. However, the best site for catheter insertion is controversial. Lack of definitive information in critically ill …

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.

2003年3月3日 · To describe complications of different arterial cannulation sites, correlating them with line obstruction, local and distal ischemia, infection and thrombosis. Materials and methods A prospective, observational study of the arterial cannulations performed in a clinical and surgical intensive care unit from October 2001 to November 2002.
