The maximum amount of air you can exhale after normal exhalation is fittingly called the expiratory reserve volume. The actual amount of air can vary from person to person, depending on size the of thoracic cavity and fitness level.
Atmospheric air has about 20.5% oxygen and our lungs only extract about 4.5% oxygen, so the air we exhale has about 16% oxygen, 4.5% CO2. The air we breathe into the victim then has 16% oxygen for their lungs to extract oxygen from.
Only a proportion of the air exhaled is carbon dioxide there is plenty of Oxygen there to do what is required under normal circumstances. People don't use all of the oxygen they breath in, a % of it is blown right back out of the body again.
There is not, and cannot be, a number for one person for this or any other physiological measure.
To get tuberculosis, a person must be exposed to the air exhaled by an infected person for an extended period of time in a confined area.
Yes
Respiratory volume or respiratory minute volume is the volume of air which can be inhaled or exhaled from a person's lung in one minute.It is normally consider when a person on a ventilator for breathing problem due to sickness or injury. It is calculated by taking the tidal volume( or lung volume ) and multiplying it by the respiratory rate( the number of breaths per minute a person is taking).
I would guess that it would have to be 100%. Aurely, you cannot have only a fraction of a person playing!
Because air is made of of oxygen and co2, so you take in the oxygen and blow out the co2.
It cannot really be proved, but a fair amount of people on WikiAnswers who post questions and answers cannot spell properly. Just like the person who replied, before I changed his/her answer, who had degraded your question into a mockery, cannot spell properly.
Because you're re-breathing exhaled air - every time you breath the same air in, you're taking in some of the remaining oxygen, and replacing it with exhaled CO2
