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.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
