Differences between oscillometry measurements obtained by MostGraph-01 and MasterScreen-IOS in patients with asthma

Area of Science:

• Pulmonary Physiology
• Medical Device Technology

Background:

• Oscillometry devices, including MasterScreen-IOS® and MostGraph-01®, aid in assessing obstructive lung diseases like asthma.
• Direct comparison of oscillometry measurements between MasterScreen-IOS® and MostGraph-01® in asthma patients is lacking.

Purpose of the Study:

• To determine if significant differences exist in oscillometry measurements between MasterScreen-IOS® and MostGraph-01® in asthma patients.

Main Methods:

• Retrospective analysis of oscillometry data from 95 asthma patients.
• Measurements were obtained using both MasterScreen-IOS® and MostGraph-01® devices.

Main Results:

• Strong positive correlation observed between the two devices.
• Specific parameters (R5, R20, ALX, Fres) showed lower values with MostGraph-01®, while X5 values were higher.
• Correction equations were developed to convert measurements between devices.

Conclusions:

• This is the first study comparing MostGraph-01® and MasterScreen-IOS® using clinical asthma data.
• While values show slight variations, they are generally comparable.
• Developed conversion equations can facilitate inter-device comparison of oscillometry data.
