The official (Ardito Desio) report of the Compagnoni/Lacedelli climb stated that the team had to climb the last part of the route without the Oxygen.
This has been demonstrated completely false because the pics on the summit are confirming they used oxygen up to the summit(masks and bottles).
Also the timing can support the availability of the oxygen up to the time they reached the summit.
This is a sad history that should (must) be re-written by Club Alpino Italiano admitting the truth on the great contribution of Walter Bonatti (accused playing dirthy tricks and using the oxygen reserved to the top team) for the conquest of K2.
Walter Bonati offers a fascinatingly, disturbingly different version of the final few days of the Italian K2 expedition in 1954. This version, long discreditted, is now given more credence thanks to recently discovered photos and Bonati's long-held physiological arguments. There is strong evidence that, among other things, the summit team did not run out of oxygen on the final summit bid. Readers are referred to a detailed discussion in Walter Bonati's "Mountains of My Life" referenced in the books section of this peak.
Wait a minute - NOTHING has been demonstrated about the use of oxygen. The only fact generally accepted is that, in all probability, the location of the last camp was different in respect to the "official" location (the one you see in the maps), and thus Bonatti could not have reached the camp for the night in any case (if this was done deliberately, it's another thing).And Compagnoni's behavior towards Bonatti was decidedly unfair, but that's another thing.
The pics shows only that they arrived to the summit with their masks stiill attached to the gas bottles, nothing else. This could have been amply justified by the need to protect the mouth from the cold. Also, it's demonstrated that Compagnoni and Lacedelli arrived to the summit in - let's say - an very depleted psychological state, so it's difficult to explain their actions in normal rational terms. Lacedelli, in his recent memory book, has - in my view - very clearly re-affirmed that the oxygen finished 200-300 meteres below the summit.
I don't think Bonatti used the top team oxygen for the simple reason that (as everyone knows) the oxygen was mainly useless, because of it's gas mix was wrong (only four bottles were used in the entire expedition). Prolonged use would have caused chest pains, etc.
Bonatti's smear campaign against the K2 team, while partially justified by his forced bivouac with Madhi (surely a terrible experience) and his mistreatement by Compagnoni, has gone way too far. It's a very, very, VERY Italian attitude: while in other countries they would have treasured such an accomplishment as a source of national pride, in Italy we're basically reducing one of the greatest mountain feats ever to a bar room brawl (with all the added journalistic hypocrisy of "making all more human" - yeah, sure!). Whatever really happened on the mountain, Compagnoni and Lacedelli arrived to the summit, and Bonatti didn't. His contribution was huge, but the same can be say of Abrham and Rey, who did most of the "dirty work" to equip the route on the Black Pyramid.
In a departure from the typical expedition documentary, this video chronicles the attempt of the International K2000 Expedition to climb K2's Abbruzzi Ridge. Narrated by a six-inch Gorilla named Murph, who attempts to be the first of his species to ascend the mountain, this often humorous look at an otherwise serious undertaking offers stunning views of the route and surroundings, as well as introducing the viewer to the colorful Pakistanis who essential to the success of the trip. Voted " Best Mountaineering Film" at the Vancouver Int'l Mountain Film Festival 2002. This film is produced By American Billy Pierson who reached the Summit of K2 on 7/30/00 as part of Gary Pfisterer's expedition. The film is about 56 minutes... VHS
It will be informative if you can add BOOKS ON K2 in table of contents. Wilco van Rooijen the leader of Norit K2 Expedition 2008 recently publish his book on K2 by the name of "Overleven op de K2" in dutch language.

wrong mountaineering
there was a national geographic expedition in 2011. this is utter nonsense. nationa geographic should be ashamed of this . you bloodly take 4 tons of equpment and 14000 feet of rope. this is not mountaineering. i could just land up on the top of k2 with an airplane. or we can take a platoon up the k2 or a whole battalion. if you mountaineers have the balls, try to go in groups of 2 or 3 up this mountain like i will do i one day or don't attempt it. shame on you and shame on national geographic for all the environmental damage. i am least impressed!

If you are a mountain Enthusiast then the below articles about high Altitude is very informative.
What is high altitude sickness?
Understanding High Altitude Sickness.
The ups and downs of mountain travel. Learn altitude’s effects on the body to combat mountain sickness. High-altitude illness afflicts novices and experienced mountaineers alike. Acute mountain sickness (AMS), high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE), usually occurring above 2,500 meters (8,202 feet), can lead to an epic. As a climber and nurse, I’ve encountered many ill climbers. Understanding altitude illness will reduce your risk for an emergency in the mountains. 
High altitude starts at 1,500 meters (4,921 feet). At high altitudes, air pressure decreases (hypobaria), resulting in “thinner” air—that is, oxygen molecules spread farther apart. We take in less oxygen when breathing, resulting in less oxygen being absorbed in the lungs and delivered to the body. A low-oxygen state, whether in ambient air or in the body, is called hypoxia. Hypobaric hypoxia causes multiple effects: Heart and respiratory rates increase immediately, improving oxygenation. Muscle fatigue, sleep apnea, changes in metabolism, altered hormone secretion, fluid retention, and swelling of the hands, feet, and face are common. Haemoglobin production and urination increase within two days at altitude as the body adjusts (acclimatises). And weight loss may occur after about a week.
