Kēia ke kaʻina hana no ka muli i ka hana o nä hawewe kani, i ke alapine (frequency) o ka oscillation i mea ole audible i ka pepeiao o känaka. Like ka küpinaÿi, ka mea i lewa mai kekahi mau nā'aʻaʻa me kekahi ikaika, haliu ae la ia i loko o ke kiʻi i ka hōʻike ma luna o ke kanaka hoʻoponopono.

• Manawa hōʻike abnormalities o fetal? Acaeoey.

Ma hāpai keiki, wā e hiki mai makuahine, e pono e hele aku e ike i ka oaeouee? Fetal ultrasound ekolu.

Ka mua ua paa no ka manawa o 10 a hiki i 14 pule. O ka papa kuhikuhi hana o keia ina hana - mea e kuhikuhi i ke alo o nā mā ma ka fetus (e laʻa me, hydrocephalus a Down ka maʻi pale) a me ka manao paa o ka lā o ka hanau ana. I Ina o ka loaʻaʻana o ka pathology kauka hoʻoholo i kekahi mea e pili ana i ka mau nō lā hoʻi o ka hāpai keiki, a no ka noho pakele no ka mea, (o ka papa, a me ka 'ae' ana o ka makuwahine).

Ka lua o ka poʻe akamai lākou fetal ultrasound pono e i waena o ka 20th a me ka 24th pule. I keia manawa, ke fetus ua, ua maopopo i hanaʻia a pau na nā loko, a me keia study ua i lawelawe 'ia e noiʻi i ko lakou ulu ana. Inā ka mea, huai ae kekahi abnormality, ka mea, ua hoʻohana 'ia i loko o utero lapaau. ¶ A i loko o ka lua o ka ao, ke akahele lawe placenta moku'āina Ka Ikepili, a me ka nui o amniotic loli.
