What is a spiroergometry?

In the case of spiroergometry, as in spirometry, the lung volumes and ventilation size are measured. In this examination however, the patient is subjected to physical stress during the examination, usually by riding an exercise bicycle, a so-called bicycle ergometer.

When is a spiroergometry necessary?

Spiroergometry is used for the diagnosis of cardiovascular and lung diseases. This method can also be used for performance diagnostics, such as for athletes.


In a similar way as for the stress-EKG, the patient is subjected to physical stress for this examination. This usually takes place on a bicycle ergometer. The patient wears a face-mask, which is connected by a tube to a measuring device which measures and graphically displays the lung volume and ventilation size. This enables the doctor to tell whether the respiratory tract is constricted or displaced (obstructive ventilation disorders), or whether the lung volume is reduced (restrictive ventilation disorders).

During the examination, an ECG is produced, and the blood pressure and heart rate recorded.

The examination is carried out at our clinic on an out-patient basis.


A spiroergometry takes about one hour.


Spiroergometry is a low-risk examination. Severe reactions are possible, but occur very rarely, and are preceded by warning signs, which are recognised by the doctor in charge in good time. The examination is then discontinued.
