What are the importance of road signs?

Answer 1

Vital signs are VITAL! They give health care professionals a quick, easy way to determine if someone is sick, or how sick they are.

So what are they?

Temperature: Normal human body temperature is about 98.6F - but this can vary from person to person, and will also vary throughout the day, and depends on where the temperature is taken. Rectal temperatures are usually the most accurate.

Heart Rate: Simply, how many times your heart beats per minute. The normal range for an adult HR is typically placed at 60-100 and can be further described as weak/strong, regular/irregular, etc.

Blood pressure: A measure of many things - how much blood or "volume" a person has, how a person's heart is working, and how the rest of the body is responding to those things. Normal blood pressure should be less than 120/80. Of course, this guideline is meant to classify high blood pressure, and LOW blood pressure is also dangerous!

Respiratory rate: How fast a person is breathing in breaths per minute. The normal range is about 12-20 respirations per minute - AT REST.

Some professionals argue that WEIGHT should be included as a vital sign. A weight that is too high or too low for a person's body size can indicate illness. Weight changes are also very important in monitoring health and disease.
