conclusions thus, we can conclude that a simulator system using an extracorporeal circulation system can be set to different models of dialyzers, and that the reproduced treatment scenarios can be used for simulation training. results the results of the tests demonstrated successful activation of the alarms by the dialysis apparatus, which were appropriate for each of the five types of accident...

UNLABELLED Although the mechanism of tourniquet-induced hypertension is still unclear, plasma norepinephrine concentrations continuously increase in parallel to arterial blood pressure during tourniquet inflation. Clonidine attenuates hyperadrenergic and hyperdynamic responses. We investigated the effects of clonidine on prolonged tourniquet inflation. Twenty-nine patients scheduled for electiv...

This study was performed to compare continuous Finapres (FIN) and intrabrachial (IAP) blood pressure in healthy elderly volunteers. Fifteen elderly subjects (age 71 to 83) without cardiovascular disease and an intraarterial mean (range) systolic and diastolic blood pressure of 162 (122 to 195) and 73 (62 to 88) mm Hg, respectively, participated in the study. A 10-min head-up tilt, 10 min active...

To the Editor:—During a recent living-related orthotopic liver transplant, we observed a significant variation between the radial and femoral arterial pressure waveforms immediately after line placement. The right radial arterial pressure was 30 mmHg higher than the right femoral arterial pressure. The radial arterial pressure correlated with the upper extremity noninvasive blood pressure. Arte...

We studied the effect of section of both carotid sinus nerves on arterial blood pressure in nine unanesthetized dogs. Four to seven recording sessions were conducted on each dog before and after sinus nerve section (SNS). During each session, histograms of mean arterial pressure during each heart cycle and of heart rate were assembled over 75 minutes. Then, responses to rapid aortic injection o...

The Bainbridge reflex, i.e., the effect of rapid saline infusion (1.1 +/- 0.1 liters) on heart rate and arterial and atrial blood pressures, was examined in 12 intact conscious dogs; mean arterial blood pressure rose by 33 +/- 3 (SE) mm Hg, mean atrial pressure by 14 +/- 1 mm Hg, and heart rate by 75 +/- 9 beats/min. After beta-receptor blockade, heart rate rose slightly less (+49 +/- 5 beats/m...

Increased intracranial pressure was induced in anaesthetized dogs by application of liquid nitrogen to the dura mater. Intracranial pressure and cerebral blood flow were measured, together with arterial blood pressure and arterial and cerebral venous blood gases.Carbon dioxide was administered intermittently to test the responsiveness of the cerebral circulation, and hyperbaric oxygen was deliv...

Oscillometric blood pressure devices tend to overestimate systolic blood pressure and underestimate diastolic blood pressure compared with sphygmomanometers. Recent studies indicate that discrepancies in performance between these devices may differ between healthy and diabetic subjects. Arterial stiffness in diabetics could be the underlying factor explaining these differences. We studied diffe...
