2. Introduction : -
- . Fever also referred to as pyrexia .
-. As having a temperature above the normal range to due to an increase in the body’s
temperature set point
-. Fever is not a disease.
-. It is sign fever it is protect action of the body because the rise in temperature prevents
Growth of organism causing the disease.

3. Definition : -
▪ Fever is elevation of the body temperature that exceeds normally daily
variation and occurs in conjunction with an increase in the hypothalamic set
point for eg 37•C – 39•C
OR
▪ Fever is also referred to as pyrexia is defined as having a Temperature above
the normal of 98.6•F (37•C).
OR
▪ Body temperature above the usually range of normal 36.6 to 37.2•c , 98 -
99•F

4. Cause of fever : -
▪ Chemical substances coffeine and
cocaine directly injected to the blood
stream
▪ Infection & inflammation disease
▪ Severe hemorrhage
▪ Hot environment
▪ Neurogenic factor like injury to
hypothalamus
▪ Side effects of therapeutic drug

5. ▪ Age
▪ Exercise
▪ Hormonal level
▪ Stress
▪ Environment
▪ Circadian Rhythm
Factors affecting body temperature

6. 1. Age
▪ Normal body temperature does not change
▪ Aging older it becomes border for your body to control its temperature.
▪ A decrease in the amount of fat below the skin make it harder to say warm .
2. Exercise
▪ Both the exercise it self and the air temperature and Humidity can increase your
core body temperature .
▪ To help cool itself body send more blood circulate in skin this leave less blood in
muscle which In turn increase your heart rate .

7. 3. Hormonal levels
▪ Esterogen controls the parts of your brain that regulate body temperature.
▪ Low estrogen levels can increase your body temperature to an uncomfortable
degree resulting in hot flashes and night sweats .
4. Stress
▪ Chronic stress and expose to emotional events can cause psychogenic fever
▪ This means the fever is caused by psychological factors instead of a virus or
other type of inflammation some cause chronic stress .

8. 5. Environment
▪ This is because your body is as open system that is constantly interacting
with the external environment .
▪ At the surface level the temperature of the body peripheral temperature is
directly .

9. Types of fever
1. Onset or invasion : - the period on when the body temperature is
rising.
2. fastgium fever or stadium : - a type of fever is when body
temperature at maximum and constant at a high level .
3. Defrvensncence or decline fever : - sudden fast crisis or sudden slowly
lysis decreasing temperature to become normal .
4. Crisis fever : - fastly decreasing tempt is termed as crisis or sudden
drop in temperature is also defined as crisis.

10. 5.True crisis : - the temperature falls suddenly within few hours and touches normal
accompanied by a marked improvement in the clients condition.
6. False crisis : - a sudden fall in temperature not accompanied by an improvement in
the general condition is called false crisis
7. Lysis fever : - the gradual decrease in fever isTermed as lysis.
8. Constant and continuous fever : - A sustained fever with slight diurnal variation less
Than 2•C or 3.6•F
9. Remittent fever : - a pattern of fever that varies over a 24 hour period.
10 intermittent fever ( quotidian) : - temperature rises from normal to subnormal to
High and back at regular interval higher temperature in evening lower in morning.
11. Relapsing fever : - normal temperature for one to two days after a brief period of
Fever.

11. 12. Inverse fever : - highest temperature in morning and lowest in evening .
13. Irregular fever : - fever is completely irregular so cannot classify into any group of
fever
14. Low pyrexia : - in low pyrexia the fever doesn’t rise above 99 to 100 •F or between
37.2 And 37. 8•C
15 . Moderate pyrexia : - moderate pyrexia is fever above 100 •F to 103•F
16 . Hyper pyrexia : - another name of high fever is hyper pyrexia temperature above
105•F is termed as hyper pyrexia.
17. Subnormal temperature : - subnormal temperature may be defined as temperature
Below normal 1•c 95 to 98•F ( 35 – 36 •F )
18. Hyperthermia : - hyperthermia is remark able increase in body.Temperature due to
Excessive heat production absorption of environment heat deficient of heat loss .

12. 19 . Hypothermia : - temperature below 95 •F – 35 •F is termed as
hypothermia.
20. Mild hypothermia : - temperature between 90 to 95 •F is called mild
hypothermia.
21. Moderate hypothermia : - temperature range between 86- 90 % is called
moderate hypothermia.
22. Sever hypothermia : - severe hypothermia is termed as temperature below
86•F
23. Rigour fever : - rigours are episode in which your temperature rises often
quite quickly whilst you have severe shivering.
Stage of rigour fever : -
I . Cold stage . II. Hot stage . III. Sweating stage.
