Normal reference ranges can vary depending on the laboratory and the method used for testing. You must use the range supplied by the laboratory that performed your test to evaluate whether your results are "within normal limits."

• Heart Rate Variability Reference Range

  Use the slider below to see how your results affect your health.

  Your result is High HRV.

  High HRV means you’re getting both strong “on” and “off” outputs and your body is highly responsive to your environment. It can quickly shift its energy from “fight or flight” to “rest and digest” to easily match its surroundings.

  Your result is Good.

  VO2 max refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. The greater your VO2 max, the more oxygen your body can consume and transport to your organs, muscles, and tissues, enabling you to have better endurance and performance for a given effort.

• What are vital signs?

  Your vital signs show how well your body is functioning. They are usually measured at doctor's offices, often as part of a health checkup, or during an emergency room visit. They include:

  • Blood pressure, which measures the force of your blood pushing against the walls of your arteries. Blood pressure that is too high or too low can cause problems. Your blood pressure has two numbers. The first number is the pressure when your heart beats and is pumping the blood. The second is from when your heart is at rest, between beats. A normal blood pressure reading for adults is lower than 120/80 and higher than 90/60.
  • Heart rate, or pulse, which measures how fast your heart is beating. A problem with your heart rate may be an arrhythmia. Your normal heart rate depends on factors such as your age, how much you exercise, whether you are sitting or standing, which medicines you take, and your weight.
  • Respiratory rate, which measures your breathing. Mild breathing changes can be from causes such as a stuffy nose or hard exercise. But slow or fast breathing can also be a sign of a serious breathing problem.
  • Temperature, which measures how hot your body is. A body temperature that is higher than normal (over 98.6 °F, or 37 °C) is called a fever.
