Lapataiga mo le fa'aogaina o oloa
1. Puipuiga kesi: Fa'alogo lelei i le mama o le kesi puipui, ma le fua fa'afefiloi kasa fautuaina o Ar + 1-3% O2.
2.tafe kesi: 20-25L / min.
3.Fa'amamago elongation: 15-25mm.
4.Aveese moni le vaega ele, susu, suauu, pefu, ma isi i luga o le vaega uelo.
5. I le taimi o le uelo i fafo, pe a sili atu le saoasaoa o le matagi nai lo le 1.5m / s, e tatau ona faia ni faiga e puipuia ai le matagi, ma e tatau ona faia ni faiga talafeagai e puipuia ai le savili e puipuia ai le tupu mai o pu.
O fautuaga o loʻo i luga e naʻo le faʻamatalaga, ma o le tulaga moni o le a manumalo i le gaioiga faʻapitoa.Afai e manaʻomia, e tatau ona faia le agavaa faʻagasologa aʻo leʻi fuafuaina le fuafuaga faʻapipiʻi.
