Comparison Study of Airway Reactivity Outcomes due to a Pharmacologic Challenge Test: Impulse Oscillometry versus Least Mean Squared Analysis Techniques

Figure 1

A schematic diagram illustrating the current test paradigm. LMS, least mean squares; IOS, impulse oscillatory system; PFT, pulmonary function testing; 𝑁, number of animals; BL, baseline; Post, after bethanechol administration. Time between the first and second bethanechol doses was 10 min.
