Abstract

Amaç: Bu çalışmada Necmettin Erbakan Üniversitesi Meram Tıp Fakültesi Hastanesi’nde iç ortam hava kalitesi parametrelerini ölçmek ve hastane çalışanları ile hasta/hasta yakınlarının iç ortamla ilgili sağlık yakınmalarını tespit etmek amaçlanmıştır.
Yöntem: Kesitsel tipteki bu araştırma 28 Şubat – 22 Mart 2021 tarihleri arasında, 442 katılımcıyla gerçekleştirilmiştir. Hastane iç ortam hava kalitesi için sıcaklık, bağıl nem, hava akım hızı, aydınlık düzeyi, NO, H2S, SO2, CO, CO2 gaz ölçümleri yapılarak standartlara göre değerlendirilmiştir. Verilerin analizleri IBM SPSS 27.0 programında yapılmıştır.
Bulgular: Katılımcıların hastane iç ortamı ile ilgili en sık görülen yakınmaları yorgunluk, ortam havasından bunalma, uyku hali olarak tespit edildi. Çalışmada ölçülen hava sıcaklığı ölçümlerinin %80,3‘ünün, bağıl nem ölçümlerinin % 22,7’si standartlara uygun olduğu belirlendi. Ölçümlerin neredeyse tümünde hava akımı hızının standartlara uygun olmadığı belirlendi. Aydınlatma düzeyi ölçümlerinin %81,0’ının standartlara uygun olmadığı belirlendi. İç ortam partiküler madde düzeyi ölçümü ile tüm ortamların ISO 5 sınıfına ait olduğu tespit edildi. İç ortam gaz ölçümleri sonucu hastanede NO, H2S, SO2 gazlarına rastlanmadı. CO gazı hastanenin küçük bir kısmında tespit edildi. CO2 ölçümlerinin neredeyse tamamı standartlara uygundu.
Sonuç: İç ortam hava kalitesi parametrelerinden bir kısmının standartlara uymadığı ve buna bağlı katılımcıların sağlık yakınmaları belirlenmiştir. İç ortam hava kalitesi parametreleri düzenli aralıklarla ölçülmeli ve standartlara uygun olması için gerekli düzenlemeler yapılmalıdır.

Indoor Air Quality of a Medical Faculty Hospital and Its Effect on Those in the Environment

Abstract

Background: Indoor air quality is associated with the etiopathogenesis of many diseases. This condition also produces many medical symptoms. The purpose of the current study is to measure indoor air quality parameters in a medical faculty hospital and to determine the medical complaints of hospital staff and patients/patient relatives related to the indoor air quality.
Methods: This cross-sectional, descriptive research was conducted with 442 participants between February 28 and March 22, 2021. For the indoor air quality in the hospital; temperature, relative humidity, air flow rate, light level, nitrogen oxide (NO), hydrogen sulfide (H2S), sulfur dioxide (SO2), carbon monoxide (CO), carbon dioxide (CO2) gas levels were evaluated according to the standards. The association between socio-demographic characteristics, medical complaints and indoor air quality were analyzed in hospital staff and patients/patient relatives.
Results: It was determined that 80.3% of the air temperature and 22.7% of the relative humidity measurements in the study were in the standard limits and almost all of the air flow velocity and 81.0% of the illumination level measurements were not in standard limits. It was determined that particulate matter level was measured normal levels according to International Organization for Standardization (ISO) 5 class in the all-environmental area. NO, H2S and SO2 were detected in the hospital with indoor gas measurements. CO gas was detected in a small part of the hospital. The majority of CO2 measurements were in line with standards. The most common symptoms of the participants associated with indoor air of the hospital were fatigue, dyspnea, and dysesthesia.
Conclusion: While most of the hospital indoor temperature measurements were in accordance with the standards, most of the humidity, airflow velocity and lighting measurements were not in accordance with the standards. NO, H2S, SO2 gases were not detected in the hospital, while CO was detected in 2 areas.
