Vital signs also serve as a baseline for comparison, enabling healthcare providers to track a patient's progress and evaluate the effectiveness of treatments or medications.

What Are Vital Signs?

Vital signs are a set of measurements that reflect various physiological functions of the body. These measurements include:

Body Temperature: Body temperature is the measurement of the body's internal heat. It is an essential indicator of the body's ability to maintain homeostasis. Normal body temperature ranges from 97°F to 99°F (36.1°C to 37.2°C).
Heart Rate: Heart rate, also known as pulse rate, refers to the number of times the heart beats per minute. It is a reflection of cardiac activity and can indicate the heart's efficiency and overall cardiovascular health. The normal range for heart rate varies with age and activity level.
Blood Pressure: Blood pressure measures the force exerted by the blood against the walls of the arteries. It consists of two values: systolic pressure (the pressure when the heart contracts) and diastolic pressure (the pressure when the heart is at rest). The normal range for blood pressure is typically around 120/80 mmHg.
Respiratory Rate: Respiratory rate refers to the number of breaths taken per minute. It reflects the efficiency of the respiratory system and the exchange of gases in the lungs. The normal respiratory rate for adults is typically between 12 and 20 breaths per minute.

Understanding and interpreting vital signs are essential skills for nurses as they provide valuable insights into a patient's overall health. Accurate measurement and documentation of vital signs are crucial for effective patient care and decision-making.

In the following sections, we will delve deeper into each vital sign, exploring their normal ranges, assessing and monitoring techniques, as well as recognizing any potential abnormalities that may require further attention.
