Biamu bia ku tshiamu tshia ordinatere bidi ne mayi 1,1-difluoroethane (boiling point -24.7 C / -12.5 F) anyi 1,1,1,2-tetrafluoroethane (boiling point -26.3 C / -15.3 F). - Padi muena mudimu ukudimuna tshibombi tshia aérosol muinshi anyi wela mukana, tshiamu tshia fluorocarbone tshidi tshipatuka ne tshiosha paditshi tshipetangana ne mucosa wa mukana udi ne kapia, tshipuekesha luya lua mubidi too ne ku -25 C to -50 C (-13 F to -58 F) mu sekonde 1. - Buteyi bua minite 60 bua kukanga njila wa luya: - Ku ntuadijilu, mishiku, ludimi, uvula, ne epiglottis bidi bimueneka toke bu tshiamu tshia nzembu, bu wax, ne bikole bu dibue (frozen) ne udi umvua mutshioke. - Mu minite 15 too ne ku 90 idi ilonda, padi ludimi lukole, mukana mutekete, ne mionji ya dîyi bienda binyanguka, dipatuka dia mashika a bungi ne dibutuka dia mubidi didi difuanangane ne dia angioedema didi dienzeka, dikanga tshitupa tshia luya tshishiki. - Mukenji wa tshimpitshimpi: - **Kuindidi nansha kakese bua oxygène ikale mukumbane (SpO2). - Bua disama dia pambelu dia dikoba ku mpala anyi ku minu, udi mua kukaja lukasa mu mayi a kapia ku 37 C to 39 C (98.6 F to 102.2 F) mu minite 20 to ne ku 30; kuena ne bua kukosa tshilamba tshidi ne mashika nansha kakese.

2. Toluene ("Spray Paint") Distal Renal Tubular Acidosis and Hypokalemic Paralysis¶

Bantu badi bapuya peinture wa tshiamu, tshintu tshidi tshipepeja peinture, anyi glue udi ne Toluene (methylbenzene) misangu ya bungi udi uya ku tshibambalu tshia malu a mpukapuka mutekete kumbukila ku nshingu too ne panshi (flaccid quadriplegia): - Mushindu: Toluene udi ushintuluka mu acide hippurique ne benzoïque ne udi unyanga distal nephron hydrogène-ion pumps, udi ukebesha Distal Renal Tubular Acidosis (Type 1 RTA) ne dijimija dia bungi dia potassium (K+), bicarbonate (HCO3-), ne phosphore (PO4). - Critical Labs: Dikonkonona dia mashi didi dileja Normal Anion Gap (Hyperchloremic) Metabolic Acidosis (Serum HCO3- < 10 mEq/L, pH < 7.15, Chloride > 115 mEq/L) ne hypokalemia mukole (Serum K+ 1.1 to 2.2 mEq/L). - Didimuija dia luondapu lua mu lupitadi: Ba munganga badi ne tshia kupingaja potassium mu mishipa (KCl) ne Magnesium KUMPALA (anyi musangu umue) kumpala kua kufila IV Sodium Bicarbonate, bualu bicarbonate nkayende udi ufila potassium udi mushale mu selile ne udi wenza bua dipangisha dia mupuya ne dipanga dia tshiadi.

(Bua malu a tshimpitshimpi adi atangila malu a luya ne a toxicologie, bala Nitrous oxide (whippet) B12 inactivation, spinal cord degeneration, and frostbite burns, Dikuatshika dia maluvu mabi, dienza dia fluorocarbone, ne mukenji wa kubenga kuenza epinephrine, Dikuatshika dia maluvu ne dikuatshika dia manga: bulombodi bua diambuluisha dia lukasa, ne Kuambuluisha muena mu dîku udi ne tshilele tshia dikuatshika dia maluvu. Ela meji bua kulonga CPR ne AED ku diambuluisha dia Croix-Rouge anyi dia St John Ambulance.)
