Abstract:

An oscillometric blood pressure (BP) device designed for recording systemic BP from a finger was compared with a random-zero, mercury-column sphygmomanometer in 76 subjects recruited from the patient population and staff of a primary-care center. After both devices were placed on the left arm or finger of the left hand, three BP readings were obtained with each device in alternating fashion, thereby according random assignment. The mean for all measurements was 119.2/72.4 mm Hg for the finger device and 118.6/75.3 mm Hg for the random-zero sphygmomanometer, systolic readings were not different

Abstract:

OBJECTIVE: Secondary Raynaud’s phenomenon is a frequent condition related to occupational exposure to local vibration but has not been described in musicians. This study aims to describe cold-induced blanching of the right second and (in particular) third digits in a 67-year-old double bass player following decades of cumulative repetitive blunt trauma to the fingers from slapping the strings. METHODS: A physical examination was undertaken and systolic blood pressure measured before and after cold provocation. RESULTS: At 10ÅãC the brachial systolic blood pressure was 156 mm Hg while blood pre

Abstract:

1. Although epidemiological data links essential hypertension with insulin resistance, ‘physiological’ insulin concentrations have not had pressor effects in humans. Our previous studies suggested that hyperinsulinaemia might have effects on distal blood pressure which are not detected more proximally. Therefore, we used non-invasive techniques to determine the acute effects of insulin on proximal and distal blood pressure. 2. Blood pressure was measured in the finger (Finapres) and arm (Dinamap monitor) during a two-stage euglycaemic clamp. Values obtained during the insulin infusion were com

Abstract:

Modelflow®, when applied to non-invasive fingertip pulse pressure recordings, is a poor predictor of cardiac output (Q, litre·min-1). The use of constants established from the aortic elastic characteristics, which differ from those of finger arteries, may introduce signal distortions, leading to errors in computing Q. We therefore hypothesized that peripheral recording of pulse pressure profiles undermines the measurement of Q with Modelflow®, so we compared Modelflow® beat-by-beat Q values obtained simultaneously non-invasively from the finger and invasively from the radial artery at rest and

Abstract:

Whether blood pressure (BP) values differ when BP is measured with or without the presence of a doctor (attended and unattended BP measurements) is controversial, and no information exists on whether and to what extent neurogenic mechanisms participate at the possible BP differences between these measurements. In this study, we assessed continuous beat-to-beat finger systolic BP and diastolic BP, heart rate, muscle, and skin sympathetic nerve traffic (microneurography) before and during BP measurement by an automatic device in the presence or absence of a doctor. This was done in 18 untreated

Abstract:

We studied three Russian cosmonauts to better understand how long-term exposure to microgravity affects autonomic cardiovascular control. We recorded the electrocardiogram, finger photoplethysmographic pressure, and respiratory flow before, during, and after two 9-mo missions to the Russian space station Mir. Measurements were made during four modes of breathing: 1) uncontrolled spontaneous breathing; 2) stepwise breathing at six different frequencies; 3) fixed-frequency breathing; and 4) random-frequency breathing. R wave-to-R wave (R-R) interval standard deviations decreased in all and respi

Abstract:

For assessment of cardiovascular effects of sensorimotor work, blood pressure is commonly measured by arm sphygmomanometry. A technique introduced by Penaz makes it feasible to monitor blood pressure noninvasively and continuously from the finger artery which measures give high correlations with intraarterial measurement. This study compared blood-pressure changes induced by a standard sensorimotor task using sphygmomanometry and the Penaz-method. It was investigated whether sphygmomanometrically recorded blood pressure can be used to estimate task-induced blood-pressure changes and whether in

Abstract:

We present a novel smartwatch, CareUp ® , for estimating the Blood Pressure (BP) in real time. It consists of two pulse oximeters: one placed on the back and one on the front of the device. Placing the index finger on the front oximeter starts the acquisition of two photoplethysmograms (PPG); the signals are then filtered and cross-correlated to obtain a Time Delay between them, called Pulse Transit Time (PTT). The Heart Rate (HR) (estimated from the finger PPG) and the PTT are then input in a linear model to give an estimation of the Systolic and Diastolic BP. The performance of the smartwatc

Abstract:

Cold induced arterial vasospasm was studied in ten patients with single digit replantation, by measuring finger systolic pressure at different finger temperatures. Each patient was examined three times; within 2 weeks of surgery, after 1 year and after 3 years. The replantations were performed using long arterial and venous grafts. Cold-related vasospasm is established during the first year after trauma, and thereafter seems to be persistent. It is concluded that the subjective cold intolerance, which affects all patients after digital amputation regardless of whether replantation is performed

Non-invasive methods for assessment of the vascular effects of antimigraine drugs were evaluated with respect to their utility, variability and sensitivity in a double-blind, placebo-controlled, three-period crossover study in six healthy volunteers using an intravenous vasoconstrictor, methoxamine, as a probe drug. Changes in the internal diameter of the brachial and radial arteries were measured using ultrasound which had low between-day and within-day coefficients of variation.
