Read MoreVital signs are measurements of the body's basic functions and are used to assess a person's overall health and wellbeing. There are four primary vital signs: body temperature, pulse rate, blood pressure, and respiratory rate. Each vital sign provides important information about a person's health and can help identify underlying health conditions or other problems.
Body temperature is a measure of the body's internal heat and is typically measured using a thermometer. A fever is generally defined as a body temperature above 100.4°F (38°C) and can indicate an infection or other underlying health condition.
Pulse rate is a measure of the heart rate, or the number of times the heart beats per minute. A rapid pulse may indicate a fever, dehydration, or an irregular heartbeat, while a slow pulse may indicate heart disease or other health conditions.
Blood pressure is a measure of the force of blood against the walls of arteries as the heart pumps blood through the body. High blood pressure, or hypertension, can increase the risk of heart disease, stroke, and other health problems.
Respiratory rate is a measure of the number of breaths a person takes per minute. A rapid respiratory rate may indicate an underlying health condition, such as asthma or pneumonia.
Monitoring vital signs is an essential part of healthcare and can help healthcare professionals and first responders make informed decisions about treatment and care.
