Bukaannada soo kabanaya hore ugu wareeji qaybo daryeel yar leh (joogitaanku wuxuu gaabanayaa 25 %).
Dhakhaatiirtu waxay beegsadaan dhammaadka hoose ee xadka la qoray; waxaa loo muujiyay oo keliya sidii baahi 20 % ka yar.
Saacadaha u dhexeeya keenista la jadwaleeyay ee ogsijiinta dareeraha ah; mid kastaa wuxuu taangiga 3,000 L ah ka buuxiyaa ilaa awooddiisa. Alaab-qeybiyuhu wuxuu u baahan yahay ogeysiis 24 h ka hor, sidaas darteed muddo ka gaaban marnaba ma keento gaadhiga xiga waqti ka horreeya intaas.
Gaas kayd ah, ugu badnaan 150 L/daq — wuxuu ku dara taangiga, ma beddeli karo. Laba bangi oo buuxa oo keliya ayaa goobta yaal.
Bixiye kale: hal rar oo ilaa 3,000 L ogsijiin dareere ah, oo yimaada 18 saacadood kadib dalabka. Xilliga yaraanta waxay bixin karaan hal oo keliya.
Cutubku wuu ku dhow yahay inuu buuxsamo marka mowjad cudur neef-mareen ah ay maalin keliya labanlaab ka badan ka dhigto imaatinka daryeelka degdegga ah, kuwo badan oo iyaga ka mid ahna xaaladdoodu aad bay u xun tahay. Bukaan kasta waqtigiisa ku geli sariir ICU adigoon nidaamka ogsijiinta ka gudbin xadkiisa — oo ku jira miisaaniyadda shaqaalaha dheeraadka ah.
Celceliska sugitaanka qaybta degdegga ≤ 1 bukaan
Ma jiro bukaan sugaya 6 saacadood ama ka badan sariir ICU
Ma jirto yaraan ogsijiin wakhti kasta
Marna ha ka badnaan 2 bukaan kalkaaliye kasta
Saacado dheeraad / wakaalad ma jiraan ka hor ku dhawaaqista kor-u-kaca
Sugitaanka ugu dheer ee qaybta degdegga ee sariir ICU. Daraasad diiwaan weyn, bukaannada xaaladdoodu halis tahay ee sugay 6 saacadood ama ka badan waxay lahaayeen dhimasho sare.
longest ED wait = now − time the first waiting patient arrived (first come, first served); ≥ 6 h counts as a delayed transfer[6]
Baahida ogsijiinta oo ka timid socodka qorshaynta ee WHO ee bukaan kasta.
demand = Σ flow(patient): severe 10 L/min, critical 30 L/min[1]
Uumi-baxiyuhu wuxuu xaddidaa inta gaas ee taangigu keeni karo daqiiqaddiiba; dhalooyinku waxay ku daraan wax yar.
Ogsijiinta dareeraha ahi waxay ballaadhataa ku dhawaad 843 jibaar marka ay gaas noqoto 15 °C iyo 1 atm (861 ee inta badan la sheego waa qiimaha 21 °C); saacadaha taangigu waxay ka imaanayaan isticmaalka hadda.
gas litres (15 °C, 1 atm) = liquid litres × 843; tank hours = gas / (use × 60)[5]
Mudnaanta kale ee hawlgalka ee uu moodelku isticmaalo.
20 base beds + up to 10 surge · 10 rostered nurses · 40 % critical at baseline · tank 3,000 L liquid, deliveries fill it to capacity; a new interval moves the next truck no closer than 24 h · vaporizer 600 L/min · 2 cylinder banks on site, 120 m³ each at ≤150 L/min · one emergency load of up to 3,000 L, 18 h after the order · step-down push shortens stay by 25 %Malo-awaal: dhererka joogitaanka, tirada sariirta iyo kalkaaliyeyaasha, miisaaniyadaha shaqaalaha, cabbirka taangiga, uumi-baxiyaha iyo dhalooyinka, iyo shuruudaha bixiyaha degdegga waa qiyam muunad ah oo loogu talagalay isbitaal cabbir dhexe ah.
Xakamaynta taxadarka ah oo ah arrin baahi.
demand × 0.8 when conservative titration is applied[7]Malo-awaal: kaydka 20 % waa muunad. Yoolalka ogsijiintu waa go'aan caafimaad oo loo qaado bukaan kasta; jilaahan wuxuu tusayaa oo keliya saamaynta sahayda.
Aan-kala-sooc: abuurahaha mulberry32 oo abuur leh; qaybinta la isticmaalay — isku-mid, tibaax (CDF rogan), caadi (Box–Muller), Poisson (Knuth). Abuurka waa la muujiyaa waana la wadaagi karaa.
