Complex mechanism: Interplay between the brain stem, blood levels of carbon dioxide and the diaphragm. Impulse to breath is generated from the brain stem and is generated based on the blood levels of carbon dioxide. The impulse is then carried to the diaphragm via nerves.The diaphragm contracts and the chest unit (lung+chest wall) move to get air in. Getting air out of the lung is a passive process.

Mech. Ventilation: When you require mechanical ventilation to assist with breathing for a prolonged periods of time, there are clearly compromises in your pulmonary function. Some say that these compromises are irreversible based on past medical history. After prolonged ventilation, it is recommended to increased ability to exercise (rehab) as soon as possible. Unfortunately, some patients don't return to baseline.

Can breathing in gasoline fumes get you sick?

Yes: Volatile fumes from gasoline, glue, paint, etc..., are bad because they diffuse throughout the body after inhalation. The fumes one smells at a gas station are diluted by the air, so don't cause illness. If one purposely sniffs gasoline or glue, or accidentally gets too much fumes while painting inside a closet, he can get damage to the lungs, brain, etc..., especially with repeated exposures.

Gasoline contains aliphatic hydrocarbon, benzene, and organic lead. Inhalation of gasoline fumes may induce euphoria and feeling of invulnerability. Higher doses result in dysphoric symptoms including hallucination, agitation, and confusion.

While you're at work is it okay to have someone spray paint a machine next to you when you're breathing in the fumes?

Not a good idea: Spray painting should be done in an area with adequate vwntilation so you don't have to be exposed to a lot of fumes.
