Why would deep or heavy breathing make a person want to pass out if he or she was actually consuming more oxygen?

Actually, it is due to the amount of carbon dioxide (CO2), not oxygen! Heavy breathing, hyperventilation, etc. will cause you to blow out more carbon dioxide than normal from the lungs. This leads to a shift in the blood pH to a more alkaline (basic) condition. A shift from normal blood pH can lead to dizziness or passing out. The basic chemistry: CO2 + H2O H2CO3 H+ + HCO3- (bicarbonate) Usually, the amount of CO2 exhaled is roughly equal to the amount being produced by the body's metabolism. Thus the CO2 in the blood is relative constant, and the concentration of H+ (acid ion) is constant. You can see that if you remove CO2 from the system faster than normal, then eventually the H+ concentration will go down and the system becomes more alkaline. In fact, if for some reason the blood has become more acidic than usual, the brain will try to compensate by causing the body to breath heavier and more rapidly, thus removing excess acid ion.

What are the changes that occur in breathing and heartbeat as a person climbs a mountain?
when a person climbs on a mountain the breathing of a person will become difficult because the rate if oxygen is more
What are the procedures for breathing failures?
Usually you would intubate the person and and get them on a ventilator or oxygen
Why should everyone keep breathing?
Breathing is one of the components of the respiring. When a person respires, the person will breath in oxygen and exhale (breath out) carbon dioxide. Oxygen replaces carbon dioxide which is toxic in large amounts and keeps the body healthy.
What does it mean when a person continues breathing heavily for some time after exercising in order to repay an oxygen debt?
When a person continues breathing heavily for some time after exercising in order to repay an oxygen debt, it means that the supply of oxygen in less than the demand. This means that the body is working hard and the amount of oxygen cannot cope with the level of activity.
Is there any danger to a healthy person from high altitude breathing?
There is danger to a healthy person from high altitude breathing because the oxygen level is very low which could possibly cause a heart attack or stroke.
What is the sign that a person has accrued oxygen debt?
They are breathing heavily and rapidly to expel the excess carbon dioxide out of their systems.
How efficient are your lungs at capturing oxygen from the air?
Our lungs are extremely efficient at capturing oxygen from the air. However, it will vary from person to person, as it generally depends on breathing patterns of an individual and if they have an upper respiratory ailment.
What is the purpose of rescue breathing?
When a person has stopped breathing and can not breathe on his own, rescue breathing (or Mouth-To-Mouth Resuscitation) is given to try and saved the persons live (in addition to CPR and/or defibrilation).
What is mouth to mouth called in water safety?
Resuscitation. It's the practise of transferring oxygen from a person who is breathing to a person who is not breathing, in the hope of helping them to breathe on their own before they become brain dead and can not be brought back to life.
Is oxygen found in people?
Yes, especially in people who are still breathing, in which the element oxygen can be found in the lungs. Most of the oxygen in a living person or a corpse, however, occurs in compounds such as sugars and fats.
Would breathing pure oxygen cause a large increase in oxygen transport by the blood in a person with a low alveolar oxygen?
We know that our blood has a pigment called Haemoglobin,which gives characteristic red colour to blood.A haemoglobin molecule carries a maximum of 4 oxygen molecules,and is called 100% saturated when it does so.So,breathing pure oxygen doesn't increase the transport of oxygen.
Can a person Photosynthesize?
Photosysthesis is something a plant does. It uses sunlight to convert carbon dioxide to oxygen. A person can't do this. A person actually breaths in oxygen and breaths out carbon dioxide.
