what is meaning of hypoxia and asphyxiation
Answers
Hypoxia
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body.Hypoxia in which there is complete deprivation of oxygen supply is referred to as anoxia. It is of two types mainly
A. Generalized Hypoxia
B. Local Hypoxia
Asphyxiation
Asphyxia or asphyxiation is a condition of severely deficient supply of oxygen to the body that arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects primarily the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by an inability of an individual to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death.Situations that can cause asphyxia include but are not limited to: the constriction or obstruction of airways, such as from asthma or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; environments where sufficiently oxygenated air is present, but cannot be adequately breathed because of air contamination such as excessive smoke.
An example of asphyxia is choking.
