as such its very vague. because it depends on part to part if the upper limb. loss of blood supply to any of the body organs can lead to avascular necrosis i.e death of the tissue due to loss of blood supply. some parts are very sensitive to this as necrose immidiately after loss of blood supply whereas some parts can resist the stress and necrose after some time. but its generally said that that the avascularized part's blood supply should be fixed within 5 to 8 hours(for muscles generally) (but brain dies if it doesn't get fresh blood supply within 15 minutes as it can utilize only glucose)

How long can the human heart live without oxygen?
The human heart can typically survive without oxygen for about 20 minutes. After this time, irreversible damage can occur leading to cardiac arrest and possible death. Immediate medical intervention is crucial in such situations.
Can you live without an heart?
No , you cant live without a heart. The heart is reasonable for circulating the blood around the body. Blood carries the oxygen, which the body needs to survive. The only exception to this is someone had a artificial heart, it would be doing the same work as a human heart.
Why is the heart in the human body?
so that blood can pump through our bodies and provide our organs with oxygen so that we can survive.
How long can the average human brain live without oxygen?
The average human brain can survive about 4-6 minutes without oxygen before permanent damage occurs. After 10 minutes without oxygen, irreversible damage and death are likely. Immediate medical intervention is crucial to restore oxygen supply to the brain.
Which gas do human being need to survive?
Humans need oxygen to survive. Oxygen is necessary for cellular respiration, which allows our cells to produce energy. Without a steady supply of oxygen, our organs and tissues would not function properly.
Do all cells need oxygen to survive?
No, some cells can survive without oxygen through a process called anaerobic respiration. However, most cells in the human body require oxygen to generate energy efficiently through aerobic respiration.
Would a human suffocate on Mars?
Yes humans will suffocat on Mars. Human depend on Oxygen to breathe and without oxygen, we will die. Oxygen is present in th Earth's atmosphere and it is not on Mars. To survive on Mars, we need to use an astronaut's suit with oxygen support.
Is the heart important why?
The human heart is the one of the most important organs in our body. Without our heart, there would be no blood circulating through our body bringing oxygen and nutrients to the tissues.
Human beings can survive without fresh water?
yes human being can't survive without fresh water
How can a human survive without water?
We cannot survive without water for three day
Why is oxygen important your body?
Oxygen is important to human body because it aid in breathing
What is the lowest amount of oxygen a human can survive on?
The lowest amount of oxygen a human can survive on is approximately 10% oxygen concentration. Below this level, hypoxia (oxygen deficiency) can occur, leading to symptoms such as dizziness, confusion, and eventually unconsciousness if not corrected.
