they consume 20-25 % of all oxygen used by the body at rest
The test used to measure how much oxygen is taken in with every heartbeat is called pulse oximetry. This test estimates the oxygen saturation levels in the blood by measuring the absorption of infrared light in pulsating blood.
you cant get too much. once the air has reached 100% oxygen no more can get in the air. if you breathe it in, you might feel a bit dizzy as you're not used to it but its not harmful at all, just not used to it
lool well oxygen is pretty much needed for life. oxygen is used for oxidation purposes in our metabolism to synthesise ATP (energy), that's why you breathe it in. Without oxygen, you woudlnt be alive.
It is not confirmed how much oxygen Edmund Hillary and his father used at the top of Everest as they reached the summit without supplementary oxygen. They were the first to successfully reach the summit of Mount Everest in 1953.
During anaerobic respiration, no oxygen is used. Instead, cells rely on other molecules, like glucose, to generate energy in the absence of oxygen.
The percentage of oxygen in inhaled air by humans is approximately 21%. This oxygen is then absorbed by the lungs and transported by the blood to the cells where it is used for energy production in the body.
it all depends on how much water is being used
A non-rebreather mask can deliver 60-80% oxygen when used with a flow rate of 10-15 liters per minute. This high concentration is achieved because the mask has a reservoir bag that fills with oxygen to ensure a constant supply of oxygen to the patient.
oxygen
The Earth uses approximately 6.5 trillion kilograms of oxygen annually through processes like respiration by living organisms and combustion. The majority of this oxygen is consumed by oceanic phytoplankton through the process of photosynthesis.
