BACKGROUND Cryptogenic fibrosing alveolitis (CFA) is an uncommon disorder of unknown aetiology characterised by interstitial fibrosis which typically shows a restrictive pattern on pulmonary function testing. Some patients with CFA and relative preservation of lung volumes have been described and it has been suggested that their volume preservation may be due to concomitant emphysema. In a retr...

Communications to the Editor ticed for days with a laryngeal mirror until he was able to tolerate the examination without a topical anesthetic. Indeed, using a lightbulb, head mirror, wall mirror and laryngeal mirror, he learned how to visualize his own larynx. When the next opportunity arose, Mr. Brubaker again volunteered to sit for the photography session, this time without a topical anesthe...

Lung volumes in irreversible diffuse obstructive pulmonary syndromes (DOPS(I)) have been studied by using an analog of the lung that simulates an 18-breath nitrogen washout. The functional residual capacity (FRC), the dead space volume (Vd), the distribution of ventilation, as well as the pattern of lung emptying have been measured in normal subjects and those with obstructive syndromes. The Vd...

We have measured lung mass and trachea dimensions in 46 giraffes of both genders ranging in body mass from 147 kg to 1441 kg, calculated static and dynamic lung volumes, and developed allometric equations that relate changes in them to growth. We found that relative lung mass is 0.6±0.2% of body mass which is significantly less than it is in other mammals (1.1±0.1%). Total lung volume is signif...
