New spirometry interpretation algorithm. Given the limitations of the currently available algorithm, 4 members of the Primary Care Respiratory Alliance of Canada have proposed a new algorithm (Figure 1) where spirometric diagnostic criteria for both asthma and COPD are included and consistent with current guidelines. 1, 2 The new algorithm focuses on the FEV 1-FVC ratio … Without interpretation, data collection is a meaningless exercise.

When chest physicians interpret spirometry data, they know that the tested values of vital capacity (VC), forced expiratory volume in one second (FEV1) and the ratio of FEV1/VC are determined by a complex interplay among the size of the lungs, pulmonary compliance, and airway resistance. These physicians recognize the typical patterns of spirometric values that … in clinical practice.
