The ventilation system of childbirth shed is divided into positive pressure ventilation, negative pressure ventilation, equal pressure (or micro positive pressure) ventilation mode, and natural ventilation. Positive-pressure ventilation and equal-pressure (or micro-positive) ventilation modes apply to filtration systems, there are also negative pressure ventilation for the mode of filtration system, natural ventilation used in the traditional independent building design, the current modern pig house has been used, Olupapula luno okusinga lwanjula engeri esinga okumanyibwa ey’okunyigirizibwa okw’okunyigirizibwa okw’okulabirira okuzaala mu nkola y’okufulumya empewo.
Mu mbeera ya non filtration negative pressure, okusinziira ku ngeri ez’enjawulo ez’empewo eyingizibwa, naye era nga zigabanyizibwamu empewo y’akasolya, akasolya akanyogoza kateni mu mbeera y’empewo, n’akasolya nga ogasseeko empewo empanvu ey’engeri y’awamu eya kateni. ebbugumu ery’ebweru ery’omu kyeya ery’ekitundu eky’obukiikakkono eky’obukiikakkono mu China tegisukka oba waggulu katono ku ddiguli 30 , esobola okutwala akasolya mu kasolya k’obukiikakkono bw’ennyonta; Ekitundu ekirala eky’ebbugumu eringi mu biseera by’obutiti kisaana okwettanira empewo ey’akasolya n’olutimbe eyeesimbye, oba empewo ey’okunyogoza akasolya akanyogoza (omuze guno gwetaaga okuzimba akasolya ne siringi mu kiseera kye kimu nga tukozesa ebintu ebiziyiza ebbugumu, era okusinziira ku kitundu okukakasa empewo emala mu kiyumba).
