introduction:

Not all health workers are required to take vital sign. If you work directly with the patient, you will need to know how to take their temperature,pulse,and respiration because these are important indicators of your patient’s condition. If you do not work with the patient,It is still valuable to know how to measure vital signs since you cloud be in a situation where this knowledge would allow you to become a helper/ assistant.

Introduction to vital signs:

Vital signs include temperature, pulse, respiration,and blood pressure. In this unit,you will be learning about temperature,pluse,and respiration. Vital signs that indicate that body is functioning within normal limits. You mresaure these signs when you take the patient that patient’s temperature,pluse and respiration.

Temperature:

Temperature is the measure of body heat. Heat produced in the body muscles and gland and by the oxidation of food. Heat is lost from the body respiration, perspiration,and excretion. The balance between the heat produced and the heat lost is the body temperature.

ways to Increase Body Temperature:

• Exercise

• Digestion of food

• Increased enviroment temperature

• Illnesses

• Infection

• Excitement

• Anxiety

Ways to Decrease Body Temperature:

• Sleep

• Fasting

• Exposure to cold

• Depression

• Decreased muscle activity

• Mouth breathing

• certain illnesses

Temomomter:

Thr thermometer is the the instrument used to measure temperature. There are several types of thermoters- glass thermometer, chemical treated paper, or plastic thermometer, and electronic thermometer.

Glass thermometer:

A glass thermometer is a hollow glass tube with calibration lines on it. At one end of the thermometer is a bulb that is filled with mercury. The mercury is heat sensitive and rises up the hollow tube when exposed to heat, this enables you to read the patient’ s temperatur. These are three types of glass thermometer (see Figure 14.1) They are:

•  oral: 

This type is used to take a temperature by mouth and may be used for axilary.

Rectal:

This type has a rounded bulb to protect against perforating the rectum and is used to measure temperature in the rectal cavity.

security: 

This type has a stubbby bulb and is used to take rectal temperature.
