The term abnormal gravity is used in medical findings or reports when diseases or injuries can be classified in the ICD-10 catalog of the World Health Organization (WHO) according to code W49 . In the original ICD-10 catalog, this term is referred to as abnormal gravitational [G] forces . Class W49 is described as exposure to other or unspecified inanimate mechanical forces, including abnormal gravity , and can be found there in Chapter XX External causes of morbidity and mortality . In the German modification ICD-10-GM, the code is W49.9 .
description
The normal force of gravity is acting on the mass -related weight of a body on the surface. Any deviation from this value is called abnormal gravity . Smaller deviations, as they occur depending on the sea level and with respect to geographical latitudes, can be neglected here. In the sense of the ICD, only artificially generated gravity comes into question, which arises when accelerations differ greatly from gravitational acceleration.
In physics , abnormal gravity is not used as a term.
Occur
On roller coaster rides , a maximum of five times the acceleration due to gravity is allowed for fractions of a second. Influencing the blood circulation is already evident. These orders of magnitude are also reached during the launch of space shuttles , but here they act on the body for several minutes. The pilots have been trained accordingly for such loads and regularly undergo medical examinations . Fighter jets such as the Eurofighter can turn up to nine times the acceleration of gravity . Such physical loads are trained in specially designed centrifuges .
Effects
The fivefold acceleration due to gravity, for example, can already significantly impair important body functions, especially the blood circulation. Prolonged exposure to this acceleration can lead to brain damage due to the resulting insufficient supply of oxygen to the brain. Fainting begins at seven to nine times the acceleration of gravity. These effects on the human body are acutely life-threatening, but can be trained.
