Életjelek

Életjelek, meaning "signs of life" in Hungarian, refers to the physiological indicators that demonstrate a living organism is functioning. These are typically objective measurements used in medicine and biology to assess a person's or animal's health status. The most common vital signs in humans include body temperature, pulse rate (heart rate), respiratory rate (breathing rate), and blood pressure. In some contexts, pain assessment and oxygen saturation (SpO2) are also considered vital signs.

Body temperature reflects the body's ability to generate and maintain heat. A normal human body temperature is typically around 37 degrees Celsius (98.6 degrees Fahrenheit), though this can fluctuate slightly. Pulse rate measures the number of times the heart beats per minute, indicating the efficiency of blood circulation. A typical resting adult pulse rate is between 60 and 100 beats per minute. Respiratory rate is the number of breaths taken per minute, reflecting the body's oxygen intake and carbon dioxide expulsion. A normal resting respiratory rate for adults is usually between 12 and 20 breaths per minute. Blood pressure is the force of blood pushing against the walls of arteries, measured as systolic (pressure when the heart beats) and diastolic (pressure when the heart rests). Normal blood pressure is generally considered to be around 120/80 mmHg.

Changes in vital signs can indicate a wide range of conditions, from minor illnesses to serious medical emergencies. Healthcare professionals regularly monitor vital signs to diagnose problems, track the effectiveness of treatments, and assess a patient's overall condition. The specific vital signs monitored and their normal ranges can vary depending on the species, age, and health status of the individual.
