SCUBA/Skin rescue: The "do-si-do" technique

I am looking for a detailed explanation of this technique, step by step, where every hand have to be and what it should be doing. As well as body position. Also why what is being done and what should not be done...


I have had a lot of questions regarding this technique, and it seems that there are just as many explanations of how and why things are done...

What are your opinions?



Thanks

Make contact – check for responsiveness
Tap or gentle shake victim; look for escaping air bubbles; determine victim is unresponsive.

Transport victim to surface
Remove victim’s weight belt and pull it clear of body and release; keep victim’s airway open; ascend to the surface.

Buoyancy and equipment management
Maintain do-si-do position; get victim and yourself positively buoyant; remove regulators/masks

Open airway-check for breathing
Establish and maintain close contact with victim; look, listen and feel; check and open airway; pinch off nose.

Begin rescue breathing
One breath every 5 seconds; maintain contact with victim

Tow victim to safety
Maintain do-si-do position; continue rescue breathing; maintain positive buoyancy and close contact.

Do-si-do tow and In-Water Rescue Breathing, first demonstrated at Temple University in 1967

I guess that's for scuba, not for freediving!

My opinion if this "do si do" technique is attempting EAR and CPR in water is....after practicing this a complete waste of time. The dive/swim etc. has not been well planned if you find yourself in this situation where you cannot get out of the water!!...unlucky!!!

Initial 2 breaths(with pulse) ....nothing!!!! ...unlucky!!! get out the water! If that is going to take more than 3-4 mins .......

difficulty found practicing this waste of time was if the water was anything but mirror flat chances were we were just filling lungs with water doing EAR as raising the airway was so difficult. CPR was easier and plausible. With two people it was just manageable in excellent conditions but exhausted very quickly. Stab jackets etc help but as I say if you find yourself in this situation.....
