What is Fever ?
febricity is a mechanism by which the body defends itself against pathogen . Fever by itself can not cause death . It is a symptom rather than a disease and often a manifestation of a pathogenic condition occurring inside the torso . A rise in the intragroup body temperature such that it is high than 37.8 ° 100 ( recorded orally ) or 38.2 ° speed of light ( record rectally ) is defined as fever . Before we understand how a rise in temperature is capable of causing death , it is essential to understand the chemical mechanism of fever . The human organic structure has a hypothalamic thermoregulatory centre , which works to keep the interior temperature of the body between 37 ° C to 38 ° C. Any stimulation which may cause the hypothalamic set stop to arise induce pyrexia .
The most common stimulus that cause feverishness is morbific infection . Other campaign of fever include seditious processes in the body or other serious conditions such as tumour . A ascent in hypothalamic set head cause narrowing of the blood vessels so as to deoxidize the peripheral blood menses and increase the heat within the body . This is characterize by thrill . This continues till the blood supply around the hypothalamus reaches a young set period .
Fever get along down when the hypothalamic bent point is reset to a lower point . This is reach with anti - pyretic drugs such as Ibuprofen and acetaminophen , which has the property to produce heat loss by sweating and automatic vasodilation .
How High Does A Fever Have To Be To Be Fatal?
If the fever is not master , it can leave to serious complications admit end . Rise in temperature above 107.8 ° F should be plow as an exigency , as it is capable of causing death . uprise in national temperature causes denaturation or break up down of protein , which in turn hinders the normal functioning of the cells . If fever is left untreated , there may be irreversible change in the cells do cell destruction follow by tissue wipeout , organ failure and ultimately death .
How Long Is Too Long To Have A Fever?
In terms of continuance , any fever ( gamey or humble ) if it does not improve within 48 hours should be cover to a doc . It is not the temperature but the symptom assort with condition that may be black , and thus should be get by with carefully .
As a general rule , it is suggest to stay alert if the temperature climb up above 105 ° F or if there is no improvement in febricity for 48 hours . It is advise to rush the affected role to the emergency centre if such a condition arises .
