(Overhand knot, marshal knot with overhand knot stopper, ) Less than a week it will be time for the IML Summer Assessment. So this week has been focus on preparing for that. Rope Technique and knots is important and also knowledge about rappelling with temporary equipment/solution.

It looks like the pandemic will be a bit calmer, and that the most countries open up step by step for tourism. I can also see that the price of flight still is quite ok. So due to that I think its time to plan for an interesting adventure season next year. And due to that I will start a series of information about High altitude sickness. This area is huge to understand, and you need that for preventing AMS Hape and Hace etc.
High altitude knowledge.
To begin with, the human body consists of 37 billiards of cells that needs energy for workout efficient. The cells are used for transporting nerve signals, for movements or producing hormones. The cells are using a chemical energy that is stored in the molecule ATP. ATP is produced during the combustion process of oxygen and sugar. This is so called aerobic combustion. The rest product of the process is carbon dioxide and water. The carbon dioxide is toxic and need to be excreted. Many of the cells can also produce the ATP without oxygen a so called Anaerobic process. This can only be used as energy giving process for a short moment. This is the ground of why we need oxygen for surviving. The cells need a good environment for being so efficient as possible. The amount of salt, acidity will be some of the parameters that effect the cells to work as efficient as possible. This parameters is regulated by the kidneys and by our breathing. The oxygen come into the body trough the lounges. The oxygen pressure is 21 kPa, but will be reduced to 20 KPa in the moist inhaled air. At sea level this hag got no meaning, but at high altitude the increased air moister an important reason for the oxygen pressure decrease faster in the blood vs. than in the air. I will continue this next blog….
Think of a trail to a cabin in the mountains were you will be alone. A real adventure with a epic view. Here you will get a feeling of it.
See ya soon…
