Artificial Respiration | Class X

Persons who have stopped breathing because of drowning, electric shocks or smoke inhalation may be subjected to artificial breathing until their own breathing can be initiated.
At higher altitudes. the rate of respiration increases. It is because at higher altitudes the amount of 0xygen, in the atmosphere is less. But our body demands the usual amount of oxygen. Therefore, we have to compensate for it by increasing the rate of breathing.
Oxygen consumption is directly related to metabolic rate of an organism. Metabolic rate is supposed to be inversely proportional to the body size of animal generally. e.g. the rate of metabolism and respiration in a mouse will be greater than those in an elephant.
Rate of respiration also depends upon the age. Very old persons have low metabolic rate and therefore the rate of respiration in them will be less than in younger persons.
