• Spirogram reference range

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

  Your result is Normal.

  On a spirogram, the breath flow is usually shown on the X axis and expressed in liters per second, while the breath volume is shown on the Y axis and expressed in liters. A normal spirogram reveals a healthy curve that shows a jump right after the start of the expiration, then a steady and quick raise to a sharp peak, and finally a smooth and slow fall.

  A normal DLCO indicates a normal lung function. DLCO is a calculated, derived value that indirectly assesses the ability of the lungs to "transfer" oxygen to blood through the use of a test gas (namely, CO) that has a greater affinity for blood hemoglobin. A normal result does not completely rule out lung disease.

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."

  Your result is Normal.

  It is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. The normal value is about 6,000 mL (4‐6 L). TLC is calculated by summation of the four primary lung volumes (TV, IRV, ERV, RV).

• What are stress tests?

  Stress tests show how well your heart works when it's pumping hard. Some heart diseases are easier to find when your heart is working its hardest to pump blood through your body. So stress tests check your heart while you exercise on a treadmill or stationary bicycle. If you're not able to exercise, medicine can be used to make your heart work harder , as if you were exercising.

  There are different types of stress tests. They all check:

  • Blood flow in your heart
  • Your blood pressure
  • The rate and rhythm of your heartbeat
  • The strength of the electrical signals that control your heartbeat

  Some stress tests also take pictures of your heart at rest and when it's working hard. The pictures provide more detail about how your heart is working.

  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.
