Abstract: Preserved ratio impaired spirometry (PRISm) is a pulmonary function pattern characterized by a forced expiratory volume in one second (FEV1) to forced vital capacity ratio greater than 0.70, ...

The 70% ratio of forced expiratory volume in 1 second to forced vital capacity proved as or more accurate than other thresholds for predicting chronic obstructive pulmonary disease (COPD)–related ...

Recent studies show that many patients are being treated for COPD without confirmatory spirometry. In-office testing is easy and available. A recent study showed that only 32% of patients admitted to ...

August 23, 2012 — The contribution of reduced lung function to the development of subarachnoid hemorrhage (SAH) is comparable with the effects of hypertension and smoking — both known risk factors for ...
