Peak flow technique and the 'windmill' trainer in older subjects admitted with acute airflow limitation.
METHODS
peak expiratory flow technique was assessed as being satisfactory or unsatisfactory in consecutive patients >60 years with an acute exacerbation of airflow obstruction, admitted to an integrated medical and elderly unit.


RESULTS
at baseline assessment, 16 (25%) of 63 patients had satisfactory peak expiratory flow technique. After conventional teaching, this improved to 38 (60%) of 63 (P<0.0001). Further instruction using a 'windmill' device failed to improve the number with a satisfactory technique.
