1 Cardiac Massage in Microgravity Thais Russomano* João de C. Castro** Simon Evetts*** Lisa Evetts*** Lisa Evetts*** John Ernsting*** *Microgravity Lab/PUCRS, Brazil **Fundação Ruben Berta, Brazil *** ***Kings College London, UK

2 Objectives To test the feasibility and practicability of performing CPR in microgravityTo test the feasibility and practicability of performing CPR in microgravity single personsingle person no equipmentno equipment Access the victimAccess the victim Open the airwayOpen the airway Perform mouth-to-mouth ventilationPerform mouth-to-mouth ventilation Perform external cardiac massage (ECM)Perform external cardiac massage (ECM)

3 ECM - New Technique The practitioner encircles the thorax of the victim with his legs in order to hold the patient close to him whilst compressing the patients chest between his hands and legsThe practitioner encircles the thorax of the victim with his legs in order to hold the patient close to him whilst compressing the patients chest between his hands and legs

7 Cardiac Massage during Parabolic Flight

8 Method 29 th ESA Parabolic Flight Campaign29 th ESA Parabolic Flight Campaign 3 subjects3 subjects CPR manikin - Resusci Anne, Laerdal, UKCPR manikin - Resusci Anne, Laerdal, UK European Resuscitation CouncilEuropean Resuscitation Council –External Cardiac Massage: Chest Compression = mmChest Compression = mm Compression rate = per minCompression rate = per min

9 Cardiac Massage during Parabolic Flight

10 Results Number of parabolas = 93Number of parabolas = 93 Number of chest compressions = 672Number of chest compressions = 672 Chest Compression Mean +/- SE – Depth /- 1 mm – Rate /- 3.2 per min

11 Conclusion Chest compression rate and depth were close to those specified by the European Resuscitation CouncilChest compression rate and depth were close to those specified by the European Resuscitation Council The new single person technique of ECM can be performed efficiently in microgravityThe new single person technique of ECM can be performed efficiently in microgravity

12 Further Studies To determineTo determine –the maximum duration of ECM –the feasibility of performing mouth-to- mouth ventilation –minimum leg length required –upper limb strength required Techniques to be usedTechniques to be used –Body suspension studies –Water immersion studies

13 Further Studies Body suspension studiesBody suspension studies
