How best to choose an oscillometer and reference equations for your patients with asthma.

The use of oscillometry has significantly advanced in recent years, thanks to the availability of more robust and portable measurement devices. However, a major drawback is the variability among different devices, which leads to noninterchangeable results. This lack of standardization has prevented the establishment of widely accepted reference equations, complicating the implementation of oscillometry in clinical practice. This review aims to clarify these areas, suggesting the adoption of specific guidelines based on the context.
