Level of agreement on SpO2 and response time between fingertip pulse oximeter and conventional bedside pulse oximeter among preterm neonates: a tertiary care study

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Background: Fingertip pulse oximeters are used to measure peripheral oxygen saturation (SpO₂) levels in newborns and have been recommended to improve access to monitoring devices in resource-limited settings. However, evidence regarding their use in preterm neonates is limited. Therefore, this study aimed to assess the level of agreement in peripheral oxygen saturation and response time between fingertip pulse oximeters and conventional bedside pulse oximeters in preterm neonates. Methods: A cross-sectional analytical study was conducted among 201 preterm neonates admitted to the neonatal intensive care unit (NICU) of a tertiary care hospital in Puducherry, India. Preterm neonates who met the inclusion criteria were enrolled using consecutive sampling. Medical records were reviewed to obtain information on clinical and sociodemographic characteristics. Both a conventional bedside pulse oximeter and a fingertip pulse oximeter were used to assess SpO₂ and response times. Data were analyzed using paired t-tests (t-test), Wilcoxon signed-rank tests (Wilcoxon SR test), Intraclass correlation coefficients (ICC) and Bland-Altman analyses. Results: A significant difference in SpO₂ values (p
