You have now become the "King of google," Toping @MaxBottomtime.

There is a local Cal Poly English professor who gives the students a specific assignment of reseching a particular subject at the library.

Many disregard his very specific assignment and use google-- which on this subject is totally incorrect. They submit their work and are failed.

You did well--
but be careful sometimes google is totally incorrect -- an example is the dive flag - Doc Dockery had no involvement in the red & white flag but takes credit total credit for its design and development. (according to Google )

I will have some personal SWBO tomorrow

BTW, I’m just sharing info presented by the freediver experts. I know nothing about freediving as you read from my previous posts. I didn’t even know what SWBO stands for until I follow this thread.

Looking forward to read your post on SWBO :)
 
My husband was an awesome free diver. He always had the snorkel in his mouth, he exhaled slightly while underwater, and broke his depth record at age 70.

The idea behind not having the snorkel in your mouth is that if you suffer SWBO the snorkel funnels water straight in to your lungs. If someone recovers you from depth swimming up will force water into your mouth. You remove the snorkel just before your descent.

How does the snorkel funnel water into the mouth, having free dived for years and never taken the snorkel from my mouth what difference does it make if an unconscious diver has a snorkel or their mouth open?

What’s the protocol in such situation? If the rescuer sees such situation, would the rescuer remove the snorkel from the rescuee and close his / her mouth before ascending or put a reg if the rescuer were a Scuba diver?

I can imagine that as they are ascending, the rescuee’s lungs would start expanding, acting as a vacuum bag, sucking the water in and fill up the lungs with water. A 7 liter lungs full of water is like adding 15 pounds of dive weight on your body. It’ll be very heavy to lift.

Freediving HD also mentions about a blackout freediver with snorkel on might clench on the snorkel tightly which makes it difficult for the rescuer to remove the snorkel delaying giving mouth-to-mouth resuscitation.

Because you have an 1 inch tube directly connected to your mouth that can hold it in the open position. If you pass out with your snorkel out of your mouth and your mouth closed chances are it will stay that way.

My main concern would be getting to the surface
As you ascend with them let their chin rest on their chest to prevent water ingress. It is a bad situation to be in.

The problem with that idea is the first thing you learn when using a snorkel is to keep a pressure of air at the mouth piece to stop the very thing you say will happen. Has the idea been testing or did someone just dream it up?

When you pass out, your muscles would relax. I experienced it myself. When I passed out, I wet myself as my bladder was full at the time. Luckily I didn’t injure my head when I fell unconscious. I can imagine your air passage would also relax and open when you pass out.

Glad to hear that you haven’t experienced a SWBO. Make sure you don’t freedive alone too!
