2. Objectives
To test the feasibility and practicability of performing CPR in microgravity
single person
no equipment
Access the victim
Open the airway
Perform mouth-to-mouth ventilation
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 patient’s chest between his hands and legs

6. Cardiac Massage Preliminary Study

7. Cardiac Massage during Parabolic Flight

8. Method 29th ESA Parabolic Flight Campaign 3 subjects

European Resuscitation Council
External Cardiac Massage:
Chest Compression = mm
Compression rate = per min

9. Cardiac Massage during Parabolic Flight

10. Results Chest Compression Number of parabolas = 93
Number 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 Council
The new single person technique of ECM can be performed efficiently in microgravity

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

13. Body suspension studies
