Alex Abramov, leader of the expedition from base camp:
Day 12. 28 April. The expedition the 7 Summits Club Everest-2017.
The health state of members is excellent. No one is sick. We attribute this to our Experiment the USE of OXYGEN DURING ACCLIMATIZATION.
All the participants were happy to take part in the first outing to the glacier with the use of crampons and fixed rope training.
This morning another 40 Yaks gone up, its carry oxygen and a lot of things for the camp ABC (6400m) for the higher camps.
Our world record holder Lhakpa Sherpa went up with the yaks caravan. She was already 7 times on the summit of Everest and this is an absolute record for women. Doctor Sergey Larin measured her pressure: 160/100. It seems a bit high.
But doctor Sergey said that all the Sherpas has the high pressure and frenzied sexual activity.
Tomorrow we are also going to leave up to 3 days. First, we will spend a night at Middle camp ( 5800м) and we will be there at night breathing artificial oxygen. Then, we will climb up to the camp ABC (6400m) and so we will use oxygen for the first night. In the morning we will hold on-ice practice and the next night we plan not to use the oxygen for best acclimatization.
I'm afraid that the next 3 days we will have no connection... Although... we'll see.
