Depends on how low you are talking. Yes some people can survive with relatively low oxygen saturations, by compensating in other ways (ie increase the number of red blood cells).
Humans can typically survive without oxygen for about 3-4 minutes before experiencing brain damage. Without access to oxygen, vital organs like the brain and heart stop functioning, leading to eventual death. Prompt medical attention is crucial to restore oxygen supply and prevent long-term damage.
Up to 10 minutes
Cells can typically survive without oxygen for only a few minutes before irreversible damage occurs.
2 weeks
The average human can survive under water for approximately 5 minutes but no more then 10.
humans can survive for at least 100 years minimum 50 maximum 150
Humans need oxygen. However, if the travel is unmanned, no oxygen would be required.
4 days or less.
Indigenous mountain animals like the llama, alpaca, and vicuña in the Andes or the yak in the Himalayas are adapted rather than acclimatized to the low oxygen partial pressures of high altitude. Their hemoglobin has a high oxygen affinity, so that full saturation of the blood with oxygen occurs at a lower partial pressure of oxygen. In contrast to acclimatized humans, these indigenous,...
Not long with oxygen, about two seconds without it.
That totally depends on your definition of life. The short answer: None.The long answer: Millions of years ago the planet Earth had little oxygen to speak of, and anerobic bacteria (those that didn't breathe oxygen) was the dominant form of life. Then came along what's known as "The Great Oxygenation", in which Earth's atmosphere started becoming more oxygen-based. Once oxygen did appear, the oxygen breathers typically outdeveloped and outbreeded other forms of life, which if I recall correctly has something to do with oxygen being far more efficient for certain biological processes than other elements such as methane.So it's not that life actually needs oxygen to survive, it's just that oxygen is far more efficient for certain biological processes -- when it's actually available. This does not answer the question. The answer is 18% oxygen at sea level. Source: PADI's Enriched Air Divers Manual
No, a rat-tailed maggot, also known as the larva of a drone fly, needs oxygen to survive. This aquatic larva breathes through a long, telescopic breathing tube called a "rat tail" that it extends to the surface of the water to take in oxygen. Without access to oxygen, the maggot will not be able to survive.
