Mouth-to-mouth Ventilation Efficiency Through Breathable Self-sterilizing Respirator During BLS in COVID-19 Pandemic (MOVERESP)

Mouth-to-mouth Ventilation Efficiency Through Breathable Self-sterilizing Respirator During BLS in COVID-19 Pandemic: a Crossover Simulation-based Study

Complex practical BLS training have been stopped all over the world due to COVID-19 pandemic in 2020. While launching the new Simulation Centre at Medical Faculty of Masaryk University in Brno, Czech Republic, teachers and students have been dealing with the risk of COVID-19 transmission during the simulation training. One of the highest risks for the transfer of COVID-19 between the medical students is during the mouth-to-mouth ventilation training in BLS.

It has been assumed that rescuers during BLS simulation training with use of breathable nanofiber respirator with layers with accelerated copper can provide efficient mouth-to-mouth rescue breaths to the mannequin in compliance with safety rules.

Study Overview

• Status: Completed
• Conditions: Ventilation During Resuscitation
• Intervention / Treatment: Procedure: Mout-to-mouth ventilation; Procedure: Mout-to-mouth ventilation with quantitative analysis

Detailed Description

The main aim of this study is to assess the efficiency of mouth-to-mouth ventilation through breathable self-sterilizing nanofiber respirators with accelerated copper in COVID-19 pandemic time. 100 volunteers (medical students trained as BLS trainers an medical students trained in BLS) will provide 2 minutes cycle of BLS according to European Resuscitation Council (ERC) guidelines 2021 wearing the breathable self-sterilizing nanofiber respirators with accelerated copper in three different mannequins: Professional Adult Medium Skin CPR-AED Training Manikin with CPR Monitor (Prestan), Resusci Anne QCPR AED (Laerdal), Resusci Baby QCPR (Laerdal). The mannequin will be utilised in a randomised order. The efficiency of mouth-to-mouth rescue breaths as "visible breath " and "not visible breath" will be recorded. In first BLS mannequin, the visibility of chest rising by the observer will be recorded. In two other mannequins, the ventilation metrics and each rescue breath evaluation in QCPR Skill Reporter will be recorded. Overall, 3 levels of visible breath according to the relation to set optimal breath volume (400 to 600 mL in adult, 30 to 50 mL in infant): low volume breath (below 400ml in adults and below 30ml in infant), optimal volume breath (between 400-600ml in adult and between 30-50 ml in infant), high volume breath (over 600ml in adult and over 50ml in infant) will be evaluated. For the primary analysis of efficiency of mouth-to-mouth ventilation, data from all three mannequins using outcome No breath / Visible breath will be evaluated. Secondary analysis will utilize data from two mannequins where detailed stratification No Breath / low / optimal / high Visible breath is possible. The mean volume of rescue breaths in the 2-minute cycle, average pause, longest pause, success in achieving the optimal breath volume, adverse events will be recorded. Regarding the technique of provided mouth-to-mouth ventilation, head tilt in adult or neutral position in infant and pinching of the nose will be evaluated.
