The impact of FFP3 respirators on the blood saturation. | LitMetric

AI Article Synopsis

  • - The study examines the impact of wearing FFP3 respirators with personal protective equipment (PPE) on healthcare workers' blood saturation (SpO2), heart rate (HR), and overall well-being while working in the ICU.
  • - Involving 21 volunteers (mostly female, median age 23), each participant experienced a three-hour shift twice: once wearing the FFP3/PPE and once without it.
  • - Results showed a slight decrease in SpO2 levels (mean -1.43%) when wearing FFP3/PPE, and well-being scores rose moderately during the shift, suggesting that a three-hour work cycle with FFP3/PPE is generally safe.

Article Abstract

This study aims to investigate whether wearing a filtering facepiece class 3 respirators with personal protective equipment (FPP3/PPE) during work in the intensive care unit (ICU) affects the blood saturation (SpO2), the heart rate (HR), and the well-being of health care workers (HCWs). This preliminary study included a group of 21 volunteers (including 16 females (76%), with a median age of 23 years). Each worker served as his own control and performed the test two times: they wore the FFP3/PPE and did not wear it for a three-hour shift in the ICU. The working with an FFP3/PPE compared to not working with an FFP3/PPE caused a significant, but within normal ranges, influence on the level of SpO2 with a mean decrease of - 1.43%. The highest reduction in the SpO2 was - 2.29% and occurred after 150 min of work. All of the score scales of the well-being markers increased consecutively but moderately during the shift while wearing the FFP3/PPE. We assume that a 3-h shift rhythm is a safe and reliable solution, i.e., three hours of working in the FFP3/PPE in the ICU, followed by rest or working without an FFP3/PPE.
