Accuracy of Heart Rate Watches: Implications for Weight Management

Accuracy of Heart Rate Watches: Implications for Weight Management

BACKGROUND Wrist-worn monitors claim to provide accurate measures of heart rate and energy expenditure. People wishing to lose weight use these devices to monitor energy balance, however the accuracy of these devices to measure such parameters has not been established. AIM To determine the accuracy of four wrist-worn devices (Apple Watch, Fitbit Charge HR, Samsung Gear S and Mio Alpha) to mea...

Effects of position on oxygen saturation and heart rate in very low birth weight neonates

Background: Desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. The aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. Methods: This interventional st...

Occupational Stress and Turnover Intention: Implications for Nursing Management

Background The main purpose of this study was to explore the status of occupational stress among hospital nurses in Isfahan, Iran. It also aimed to examine the relationship between nurses’ occupational stress and their intention to leave the hospital.   Methods The study employed a cross-sectional research design. A validated questionnaire was used to collect data from 296 nurses. Respondents w...

Accuracy of Ultra-Short Heart Rate Variability Measures

Heart rate variability (HRV) measures have been used to assess autonomic cardiac regulation. The standard lengths used in HRV analyses are 5 minutes and 24 hours. In this paper we investigated the accuracy of three HRV measures for ultra-short record length, 10 seconds, which is the length of standard electrocardiograms. The measures chosen were: Standard Deviation Normal– Normal (SDNN), Root M...
