“…Carbon monoxide, carbon dioxide, particulate matter, nitrogen dioxide, methane, and formaldehyde are shown to be major air pollutants (5-7). Polycyclic aromatic hydrocarbons, acrolein, ozone, acetaldehyde, volatile organic compounds (VOCs) like toluene, benzene, xylene, acetic acid, and phenol are present in fire smoke (2,3,(8)(9)(10). The amount and intensity of toxins may vary depending on the location and duration of the fire.…”

Objective: During interventions, firemen are exposed to fire smoke. Fire smoke contains many air pollutants. Smoke exposure may increase the risk of pulmonary and cardiovascular diseases. The aim of this study was to evaluate the effect of long-term occupational smoke inhalation on respiratory functions and related risk factors in working firemen. Methods:Between February and March 2012, 523 working firemen were retrospectively evaluated within the scope of a screening program in Ankara Numune Training and Research Hospital. The study included 250 firemen actively participating in a fire and a control group of 273 firemen working in the office. Detailed evaluation of the firemen included age, gender, height, weight, spirometric measurements (FEV 1 , FVC, FEV 1 /FVC, PEF, FEF25-75), smoking status and duration, duration of work, and comorbidities.Results: According to the results obtained from the study, FEV1 values were significantly decreased in firemen actively participating in firefıghts compared to the low-risk group. The duration of the study did not significantly affect pulmonary functions. Conclusion:Respiratory functions decrease in active working firefighters. Development of diseases related to exposure to smoke may be prevented by the development of more effective apparatus protecting from smoke, working in cycles in different fire types, quitting smoking, and regular annual screenings. Keywords: Fireman, respiratory function test ÖzetAmaç: İtfaiyeciler, yangına müdahaleleri sırasında, dumana maruz kalırlar. Yangın dumanı, birçok hava kirleticilerini içerir. Duman maruziyeti, pulmoner ve kardiyovasküler hastalık riskini artırabil-mektedir. Bu çalışmanın amacı, çalışan itfaiyecilerde, uzun dönem mesleksel duman inhalasyonunun solunum fonksiyonları üzerine etkisinin ve ilişkili risk faktörlerinin araştırılmasıdır.Yöntemler: Ankara Numune Eğitim ve Araştırma Hastanesi'ne Şubat 2012-Mart 2012 tarihlerinde tarama programı kapsamında başvuran, çalışan 523 itfaiyeci retrospektif olarak değerlendirilmiş-tir. Yangında aktif olarak çalışan 250 kişi, kontrol grubu olarak da masabaşında çalışan 273 kişi çalışmaya alınmıştır. İtfaiyecilerin yaş, cinsiyet, boy, kilo, spirometrik (FEV 1 , FVC, FEV 1 /FVC, PEF, FEF25-75) ölçümleri, sigara içme durumları ve süreleri, meslekte çalıştık-ları süre, komorbiditeleri değerlendirilmiştir. Bulgular: Çalışmadan elde edilen verilere göre, aktif olarak yangına katılan itfaiyecilerde, düşük riskli gruba göre FEV1 değerlerinde anlamlı olarak azalma saptanmıştır. Çalışma süresinin solunum fonksiyonlarını anlamlı olarak etkilemediği görülmüştür.Sonuç: Aktif çalışan itfaiyecilerde, duman maruziyetine bağlı olarak solunum fonksiyonlarında azalma görülmüştür. İtfaiyecilerde duman maruziyetine bağlı hastalıkların gelişimi, solunum yollarını koruyacak daha efektif aparatların geliştirilmesi, farklı yangın tiplerinde döngülü çalışma, sigara bıraktırma ve düzenli yıllık taramalarla önlenebilir.

“…In this regard, the Barnhard-Loyd radiographic method has good correlations with the other methodologies in estimating total lung capacity in humans (Barnhard et al, 1960, Loyd et al, 1966, Kilburn et al, 1993, Pappas et al, 1998. It considers the thorax to be a stack of five elliptical sections that allow an estimation of the lung volume by integration from measures of transverse diameters and heights in anteroposterior and lateral chest x-rays.…”

In this paper we develop a method to estimate lung volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: V * L = 0.496 · V RX ≈1/2·V RX , where V RX is a measurement obtained from the x-ray that represents the volume of a rectangular box containing the lungs and mediastinum organs. The proposed formula may be interpreted as the volume of an ellipsoid formed by both lungs joined at their bases. When that relationship was used to estimate lung volume, values similar to those expected from allometric relationship were found in four rodents. In two others, M. musculus and R. norvegicus, lung volume was similar to reported data, although values were lower than expected.
