Monitoramento domiciliar da saturação de oxigênio, frequência cardíaca, temperatura corporal e pico de fluxo expiratório em pacientes com COVID-19 e síndrome pós-COVID

Abstract

The COVID-19 pandemic caused a sudden and important increase in hospitalizations worldwide. Furthermore, infection with this virus can be characterized by being asymptomatic or by presenting symptoms both in a milder and more advanced form. Home telemonitoring is of great interest in COVID-19, where social distancing is important and a large number of people have long-term symptoms. The objective of this work was to evaluate the changes observed over 30 days in pulse oximetry (SpO2), heart rate (BPM), body temperature, peak expiratory flow (PEF) between groups of patients with COVID-19, Post-COVID and group control. This is an analytical, longitudinal, descriptive study where 87 individuals were analyzed: 29 in the control group, 29 in the COVID-19 group and 29 in the Post-COVID group. The results of home monitoring increased SpO2, heart rate, body temperature and PEF and affected these individual changes over time where an increase in SpO2 and PEF were observed over the 15-day period and a reduction in body temperature for the COVID-19 group. Furthermore, for the post-COVID group, an increase in PEF was observed during the 15 days of monitoring. For correlation analyses, they demonstrated a positive correlation between PEF and SpO2 and a negative correlation with temperature and BPM for the COVID group; and negative correlation of PEF correlated with SpO2 for the post-COVID group. Furthermore, PFE% correlation analyzes showed a positive correlation with SpO2 and a negative correlation with body temperature and BPM for the COVID-19 group. For the post-COVID group, PFE% showed a negative correlation with SpO2 and a positive correlation with BPM. These changes are consistent with the pathophysiology of these patients. We conclude that home telemonitoring can be a useful tool in investigating and managing physiological changes in patients infected by SARS-CoV-2.
