The feasibility of home monitoring of impedance with the forced oscillation technique in chronic obstructive pulmonary disease subjects.
Respiratory system resistance (Rrs) and reactance (Xrs) measured by forced oscillation technique (FOT) can be potentially used for home monitoring in COPD. Our aims were to determine the technical acceptability, adherence and variability of unsupervised, home FOT measurements over ten consecutive days. Supervised spirometry and FOT measurements were made on ten clinically stable COPD subjects at their homes at the study initiation. ⋯ Subjects who have COPD make reliable, unsupervised FOT measurements at home with a high degree of adherence. The day-to-day variability of FOT measurements was similar to that of supervised laboratory recordings. These results support the conduct of larger, longer-term studies of FOT monitoring in COPD.
