Flowmeters

01/01/2018 - "Quantification of the flow change was performed during hyperemia after a 30-s left anterior descending (LAD) artery occlusion followed by reperfusion and was compared to gold standard measurements provided by a flowmeter probe placed at a proximal location on the LAD (n = 5). "
01/01/2020 - "Subsequently, gingival reactive hyperemia was measured using a laser Doppler flowmeter. "
12/11/2014 - "Finger hyperemia was assessed by using a 2-channel laser Doppler flowmeter (MBF-3D, Moor Instruments, Ltd.). "
01/01/1994 - "Reactive hyperemia was induced by occluding the digital artery at the base of the middle finger, and the increase in skin blood flow (delta flow) was analyzed with a laser Doppler flowmeter. "
11/01/1990 - "Reactive hyperemia was measured over a locally warmed area of skin, using a laser Doppler flowmeter, following 5 minutes of suprasystolic occlusion of blood flow. "

11/01/1997 - "Child-centered asthma education can be successfully conducted in the school setting, resulting in increased asthma knowledge, improved skills for peak flowmeter and inhaler use, and a reduction in the severity of asthma symptoms."
11/01/1997 - "After asthma education, students demonstrated improvement with increases in mean scores for: asthma knowledge quiz from 9.9 (SEM = 0.44, n = 34) to 13.7 (SEM = 0.30); peak flowmeter technique from 3.9 (SEM = 0.33, n = 32) to 6.4 (SEM = 0.29); and inhaler technique from 2.3 (SEM = 0.26, n = 32) to 4.3 (SEM = 0.26). "
02/01/2007 - "Twenty-six children with moderate asthma aged between 7-14 years who had peak expiratory flowmeter (PEF) values above 80% were selected for the study group. "
09/01/2001 - "Among all eligible participants, persons with lower knowledge of asthma management (which was assessed by what to do during an asthma attack and knowledge of the correct use of a peak expiratory flowmeter and inhalers) were less likely to enroll in the trial and to attend the educational training sessions. "
06/01/2011 - "Controls received instruction from an asthma knowledge test, peak flowmeter training, and asthma brochures. "

12/01/2010 - "We evaluated the efficacy of ultrasonic doppler flowmeter-guided occipital nerve block in patients experiencing headache in the occipital region in a randomized, prospective, placebo-controlled study. "
12/01/2010 - "Ultrasonic doppler flowmeter-guided occipital nerve block may be a useful method for patients suffering headache in the occipital region."
03/01/1991 - "To explore the mechanism for facial puffiness, headache, and nasal congestion associated with microgravity and cephalad fluid shifts, the postural responses of the cutaneous microcirculation in the forehead and dorsum of the foot of eight healthy men were studied by changing body position on a tilt table and measuring blood flows with a laser-Doppler flowmeter. "

06/01/1992 - "We measured the phasic pattern of intramyocardial coronary arterial flow with an 80-channel, 20-MHz pulsed Doppler ultrasound flowmeter under moderate to severe coronary artery stenosis (distal perfusion pressure approximately 45 mm Hg group 1, n = 6) and transmyocardial blood flow distribution using radioactive microspheres while maintaining coronary pressure at a low constant level (40 mm Hg, group 2, n = 6). "
12/01/1988 - "In five experimental dogs with critical circumflex coronary artery stenosis, coronary flow (CF; Doppler flowmeter) and systolic thickening of the posterior wall (by sonomicrometry) at rest did not differ from those of the controls. "
02/01/1976 - "The effect of a proximal coronary artery stenosis on transmural myocardial blood flow during exercise was studied in nine dogs with electromagnetic flowmeter probes and hydraulic occluders on the left circumflex coronary artery. "
01/01/2020 - "The flow rate of the left-anterior descending artery (LAD) assessed by 3D UDCA was reconstructed successfully at the early diastolic and late diastolic phases and was in good agreement with an invasive gold-standard flowmeter during baseline, reactive hyperemia and coronary stenosis (r2 = 0.84). "
05/01/1994 - " In the determination of coronary artery stenosis, flow velocity at the site prior to the stenotic lesion and that of stenosis was measured by catheter-tipped Doppler flowmeter (3-Fr, 20 MHz). "

12/01/2006 - "At the end of the treatment all patients showed a reduction in portal hypertension (mean reduction HVPG = 40.2%, P<0.011), together with an improved ultrasound flowmeter pattern and a sharp decrease or disappearance of the symptoms. "
05/08/1986 - "[Abdominal ultrasonography with a Doppler flowmeter in the diagnosis of portal hypertension]."
02/01/1985 - "An ultrasonic sector scanner and pulsed Doppler flowmeter were combined to measure portal venous velocity in 19 patients with portal hypertension and compared with cineangiographic mapping of a droplet of oil released into the portal vein. "
02/22/1991 - "The authors assessed in 12 patients with compensated cirrhosis of the liver, portal hypertension and oesophageal varices, using a Doppler flowmeter Toshiba SAL 50A/SDL 01 under basal conditions, changes in the width, rate of blood flow and blood flow though the trunk of the portal vein before and after intravenous administration of 1 mg glucagon.
