Expression of bronchodilator response using forced oscillation technique measurements: absolute versus relative.
We refer to the recent study by OOSTVEEN et al. [1] on bronchodilator response in 4-yr-old children with different wheezing phenotypes. The forced oscillation technique is particularly suited to 2–7-yr-old children, and its suitability to assess bronchodilator responsiveness is still being investigated. Thus, the study is of great clinical relevance and, though of a narrow age range, is a welco...
متن کاملNasal airflow resistance measurement: forced oscillation technique versus posterior rhinomanometry.
This study was designed to determine whether nasal airflow resistance (Rn) which is nonlinear during tidal breathing, can be assessed by the forced oscillation (FO) technique. Rn values obtained by the FO technique and extrapolated to 0 Hz (Rn,FO) were compared to those assessed by posterior rhinomanometry at maximal tidal inspiratory flow (Rn,m), at a 0.5 L x s(-1) flow (Rn,F), and at a 1 hPa ...
متن کاملUsing the forced oscillation technique to evaluate bronchodilator response in healthy volunteers and in asthma patients presenting a verified positive response.
OBJECTIVE To use the forced oscillation technique to evaluate asthma patients presenting positive bronchodilator responses (confirmed through spirometry) and compare the results with those obtained in healthy individuals. METHODS The study sample consisted of 53 non-smoking volunteers: 24 healthy subjects with no history of pulmonary disease and 29 asthmatics presenting positive bronchodilato...
متن کاملAbsolute versus relative likelihood judgment
In this paper we investigate how people construct absolute and relative likelihood judgments. We document systematic violations of two fundamental probability axioms that can occur when evidence for an event H and its complement not-H are stronger than evidence for another event L and its complement not-L. First, H is judged “more likely” than L, while L is assigned a higher probability than H,...
متن کاملRelative versus absolute change in forced vital capacity in idiopathic pulmonary fibrosis.
BACKGROUND Decline in forced vital capacity (FVC) over time reliably predicts mortality in patients with idiopathic pulmonary fibrosis. The use of this measure in clinical practice is recommended by current evidence-based guidelines. It is unknown if the method of calculating decline in FVC (relative vs. absolute change) impacts its frequency or its ability to predict mortality. METHODS Patie...
