A report on Space CPR based on the Evetts-Russomano MicroG CPR technique
A report on space training in Space CPR based on the Evetts-Russomano MicroG CPR technique.
Time: 2022/3/27–3/28
Location: Haiwang dive center Chengdu Sichuan Province China
Participants: Chris Yuan (Padi instructor), Leo Wei (Padi instructor), Yanyue Lee (Free diver and Mermaid Instructor).
Our task today: CPR training for cardiac arrest of astronauts in the capsule under the condition of underwater testing of microgravity or zero gravity of the space station.
Our training and testing steps are as follows:
1 We require the rescuer to place the left leg around the right shoulder of the CPR manequin in accordance with The Evetts-Russomano MicroG CPR technique.
I, Leo, trained separately for scuba diving and freediving as shown in the video.
2 We use auxiliary straps to spatially link first responders and victims for CPR.
Leo, Yanyue and I both use freediving, do the Evetts-Russomano MicroG CPR technique and strap-assisted CPR.
Now let’s do some performance feedback:
Evetts-Russomano MicroG CPR technique:
Advantages: It is very convenient to use in microgravity space and can be rescued without other auxiliary equipment.
Challenge: We found that using the Evetts-Russomano MicroG CPR technique to clamp the rescued person with two legs crossed would consume a lot of physical strength, and the core physical strength of the first responder is also relatively high. In addition, the CPR standard requires pressing the two breasts together. The midpoint of the line, this part, the area is relatively small.
Using Auxiliary Band Spatial CPR:
Pros: Equipment is readily available, any harness, rope, or even a first aid bandage will work. When the straps are connected, the first responder only needs to gently clamp the rescued person’s upper waist with both legs, and most of their physical strength is used for CPR compression, which can be done by ordinary people. Because long-term CPR is inherently exhausting. In addition, the legs are clamped on the upper waist, the chest area is large, and it is easier to press the midpoint of the connection between the two breasts.
Challenges: Requires straps, an extra link, and the risk of entangling the body in the space if the cord is too long.
Special thanks to the mermaid instructor Miss Lee who was present today for participating in the training, because of her mature free diving ability, she did a good job with Space CPR for the first time.
As an added bonus, we’ve all found underwater Space CPR training to be a fun skill-building exercise for scuba divers and freedivers alike. Scuba divers can use it to train center buoyancy, and freedivers can use it to train carbon dioxide tolerance.
Sincere thanks to Prof. Thais for developing the Evetts-Russomano MicroG CPR technique for leading us all to contribute to the human space cause.
