Resumo
Wearable technologies become an important topic in the field of health technology for
the monitoring and storage of health-related data. Pulse oximetry is the most used
wearable in the continuous monitoring of vital signs. However, smart watches have
been occupying a space in the portion of the population that practice physical activities
with the aim of monitoring heart rate (HR) during their practice. Thus, this study infers
about the use of smart watches as an instrument for measuring HR in hospitalized
patients diagnosed with systemic arterial hypertension affected by covid-19. For this
purpose, HR collection was carried out in 30 patients aged between 40 and 80 years
old from male and female internships at Hospital de Campanha in Bacabal/MA, using
a digital watch (Fitbit, charge HR) and a finger oximeter as a reference value. The
devices (watch and oximeter) were placed on the left arm wrist and on the left index
finger simultaneously during 30 minutes of evaluation in the patients. In addition to the
HR collected by the devices, other vital signs were observed, such as blood pressure
(sphygmomanometer), oxygen saturation (finger oximeter) and respiratory rate by
analyzing the electrodes placed on the patients. ANOVA analyzes of variance were
performed followed by Tukey's Comparison post-test and Pearson's correlation test
with the aid of the GraphPadPrism version 7.0 software (GraphPad Software, San
Diego, CA, USA). The results indicated that they were patients with a mean age for the
male gender of 65.00 ± 15.39 years and for the female gender of 65.91 ± 23.06 years,
with a respiratory rate per minute of 20.47 ± 0.5679 and 20.6 ± 0.3754 for males and
females respectively, in addition to a similarity of 83.3% in HR measurements
performed with the watch (84.9 ± 4.29 bpm) in relation to those with the oximeter (88.2
± 3.75 bpm) with a Pearson correlation for r = 0.71. It can be concluded that the smart
watch can be another instrument to be taken into account during the evaluation of vital
signs with the same efficiency as that verified by the oximeter.
