Thanks for putting this information out in a well structured way.

thx for the feedback!

[@svitlanagaidai2312]

Thank you for sharing! Even our 6 years old neighbour is watching you. So feel the responsibility)))

Great work done. Good luck Thank you so much👋

[@KAIZENFREEDIVING]

thx for your comment!

Can any of this thing can happen if you only diving not more than 10-15 m deep...?!

[@KAIZENFREEDIVING]

If you are not "staying" at this depth (we use word - hangs) then chances are small. Though it is still possible for many reasons....

[@benyoucef0863]

Excellent. Thank you. I am used to take three deep breaths before diving, is this a hyperventilation?

[@KAIZENFREEDIVING]

let's call it small hyperventilation ;-) Even one long exhale will make CO2 level low than normal.

@Artemio Medina don’t hyperventilate

[@scubadiverhaley]

Forgive me if I missed this, but I’m having a hard time understanding what exactly happens to the body during shallow water black out with decreasing partial pressures. Is it not only that at a deeper depth the the O2 is at a higher concentration due to a high PP, but also that at the deeper pressures the blood is being drawn closer to more vital organs and away from non vital extremities? As you ascend its not only the decrease in partial pressure of oxygen but also the blood being drawn away from the vital organs? Please help me understand properly. Thank you.

[@KAIZENFREEDIVING]

There are many things that happen during the freedive. To name a few - perefirial vasoconstriction, blood shift, cerebral vasodilation. The main factors that will create the risk of the BO on the ascending are decreasing the O2 content in the arterial blood and decreasing of pO2. The blood vessels of the muscles are still going to be constricted on the way up, and pulmonary blood vessels are dilated throughout the dive.
