Interpretation | special findings
In everyday practice, we encounter certain findings which may prove difficult to interpret. In the following section we would thus like to present a few typical potential pitfalls and special findings.
Quantitatively speaking, normal findings, but with absent inspiratory bulbous loop due to poor cooperation.
The flow-volume-curve appears restrictive in nature. However, it follows a normal course in obese patients (see black triangle) and accordingly the spirometric parameters are within the normal range as well.
