چکیده
سابقه و هدف: سالنهاي تشريح ازجمله مکانهايي هستند که بايد همواره از تهويه مؤثري برخوردار باشند. هدف از اين مطالعه تعيين اثربخشي سيستم تهويه يک سالن تشريح با استفاده از روش استاندارد 8-16000 ISO بود.
روش بررسي: در مطالعه حاضر ضمن حفظ شأن و احترام اجساد انساني موجود در يک سالن تشريح در طول مدت پژوهش، اثربخشي سيستم تهويه يک سالن تشريح در چهار حالت متفاوت شامل: مکنده روشن، دمنده روشن، هر دو سيستم روشن و هر دو سيستم خاموش، بر پايه استاندارد 8-16000 ISO، به روش نرخ کاهش گاز ردياب (SF6) مورد ارزيابي قرار گرفت. گاز ردياب در سالن، تزريق و سپس نمونهبرداري در پنج نقطه انجام و در آزمايشگاه تعيين مقدار شد. سپس ميانگين عمر موضعي هوا و ميانگين عمر هواي سالن و همچنين نرخ تهويه موضعي و کلي هواي سالن تعيين گرديد.
يافتهها: نتايج آزمون آناليز واريانس دوطرفه نشان داد که ميانگين عمر موضعي هوا و نرخ تهويه محلي در محلها و حالات مختلف سيستم تهويه تفاوت معنيداري (0.390=p-value و 0.220=p-value ) نداشتند. همچنين اثر حالت سيستم تهويه بر ميانگين عمر هواي سالن و نرخ تهويه سالن معنيدار بود (P<0.001). آزمون آناليز واريانس يکطرفه نشان داد که سيستم مکنده بيشترين اثر را بر ميانگين عمر هوا و نرخ تهويه سالن داشت.
نتيجهگيري: بر اساس نتايج حاصله سيستم تهويه در هنگاميکه هم دمنده و هم مکنده روشن باشند اثربخشتر بود. با توجه به سميت فرمالدئيد، علاوه بر تهويه عمومي استفاده از تهويه موضعي استاندارد نيز براي ميزهاي تشريح قوياً توصيه ميشود.
