    The perils of climbing the ‘Roof of the World’ — Mount Everest The 1% Podcast

 

My guest today is Dr. Roger McMorrow.

On the 24th May 2007, at 8am, in minus 40°C, Dr. Roger McMorrow reached the summit of Mount Everest the world’s highest mountain from the South side.

In this episode we find out what it’s like to stand on top of the world, the difficulty in getting back down, find out what is the ‘death zone’, the very real possibility of dying, controlling fear, the psychology of mountain climbing, bodies on the path, how to cross a 50 meter-deep crevasse, setting up the world’s highest medical laboratory on Everest’s South Col, rescuing a young Nepalese woman on the mountain, how long it takes to climb Everest, Sherpas, the Himalayas, Nepal, attitude to risk and much, much more.

This podcast was recorded a day before news broke that Seamus Lawless had fallen and went missing on the decent after summiting Everest on May 14th.

After discussing this with Rodger we felt that it was right to release the podcast as it highlights one person’s journey to summit Everest. It also highlights the beauty and dangers of the mountain and some of the specific challenges that climbing Everest holds, as well the the dedication and efforts of those that climb the highest peak in the World.

Our condolences go out to the families of Shay Lawless and Kevin Hynes who tragically died climbing Everest this year. May they rest in peace.

Regards,

Shay

  • The ethics challenges of low oxygen experimentation

 

12:20 Why Everest?

  • Climbing Mount Everest is a well-supported undertaking
  • Combining their medical career with their passion for mountaineering
  • The result: over 100 scientific papers published

 

13:20 The study’s findings and the science of low oxygen levels

  • Humans can acclimate to oxygen levels on par with those of diving mammals, specifically the diving Weddell seal
  • The lowest recorded oxygen level is 1/3 of the level that causes death in IC patients
  • The role of mitochondria in our ability to acclimate
  • Our body’s ability to rely more heavily if needed on low oxygen-tolerant cells
  • Comparisons with the human fetus, who is able to survive on the low oxygen levels in the mother’s blood
  • “We are born with this ability”

 

15:58 Logistics of the climb

  • Delivering much of their equipment in advance, some of it by helicopter
  • The challenge of heavy, sensitive equipment
  • Creating custom equipment, tents and generators
  • The importance of Sherpa support and their unique acclimatization abilities

 

19:41 Preliminary physical training

  • Feeling like he had been practising since the age of 19
  • The importance of simply sitting in place, acclimatizing
  • The mental impact of just looking at the mountain
  • Mike Grocott’s rule for the Everest climbers: having been above 8000 m
  • Their climbing leader: Dr. Dylan, the only one who had been above 8000 m
  • The 2 preliminary expeditions to Cho Oyu
  • Their goal: getting an arterial blood gas sample
  • The challenges: shrunken arteries because of the cold and preparing an operation area under difficult conditions and limited funding

 

24:37 Learnings from Cho Oyu

  • The effects of fatigue
  • Proving that obtaining a blood gas sample was possible under these conditions

 

26:42 Weight gain and weight loss

  • Why one loses so much weight and muscle mass when climbing
  • Attempting to gain weight in preparation. The key: late-night take-out

 

28:49 Choosing to ascend the South side

  • The multiple possible routes to Everest
  • The logistical ease of bringing equipment through Nepal
  • Building relationships with the companies on the South side
  • Their priorities: 1) Safety – 2) Science – 3) Summit

 

30:27 The challenges of the climb

  • Why the biggest challenge is the mental challenge
  • The difficulty of being away from family and children
  • The importance of having alone time in separate tents
  • How one discounts and rationalizes risk
  • What it means to minimize risk

  • “I don’t like doing risky things”
  • His job as an anaesthetist: making risky surgery less risky
  • An important skill: remaining calm when things go wrong
