mechanical vibration in neonatal transport: a randomized study of different mattresses1

Pahuhopu: e hōʻoia i ka manaʻo maikaʻi loa o nā moena gel i ka hoʻohaʻahaʻa ʻana i ka haʻalulu mechanical i ka lawe ʻana i nā keiki hou, ua alakaʻi mākou i kahi haʻawina hoʻopaʻa ʻana o nā hui moena ʻehā (
ʻAʻole, ʻōhū, gel, gel ma ka ʻūhā)
Mannequin a me ka ambulance e hoʻohana ana i kahi ala paʻa (kūlanakauhale, alaloa).
Hoʻolālā Haʻawina: loiloi i ka haʻalulu mechanical ma ke ana ʻana i ka wikiwiki kū pololei o nā kūlana ʻelua: 2000-
ʻO ke kumu hoʻohālike kanaka maʻamau a me ke kahua hoʻoulu ʻana o ka halihali.
Mai ka mōʻaukala manawa o kēia wikiwiki, RMS)
Ua helu ʻia nā waiwai a me ka mana spectral density hana.
Hoʻoholo ʻia ka hopena o ka moena ma ka hoʻouna ʻana i ka vibration ma muli o ka ratio o nā waiwai RMS ma nā kūlana ʻelua.
ʻO ka lakio RMS ma lalo o 1.
Hōʻike ka 0 i ka attenuation, ʻoiai ʻo ka ratio he> 1.
Hōʻike ka 0 i ka hoʻonui ʻia ʻana o ka haʻalulu.
Mai ka mana spectral density hana, ua hoʻoholo ʻia ke alapine maoli o kēlā me kēia hui moena o ka ʻōnaehana pili i ka alapine maoli o ka ambulance.
No ka hoʻoholo ʻana i ka hopena o ke kaumaha o ke kŘkohu kanaka ma ka vibration, 300-gm mannequin.
Nā hualoaʻa: ʻo nā helu RMS i ʻike ʻia he> 1.
I ka loaʻa ʻole o kahi moena gel, ʻike ʻia ka helu kiʻekiʻe loa ma ke ala o ke kūlanakauhale.
ʻO nā moena gel i hoʻohana wale ʻia a i hui pū ʻia me nā moena pua, i hoʻohālikelike ʻia me nā moena pua a i ʻole nā moena puaʻa ʻole, e hoʻokaʻawale i ke alapine maoli o ka ʻōnaehana mai ke alapine maoli o nā ambulances, ua pale ʻia ka Vibration Amplification nui.
ʻO ka hoʻemi ʻana i ke kaumaha o ka mannequin ka mea e emi ai ka maikaʻi o ka moena gel ma ke ʻano o ka vibration attenuation.
Ka hopena: nā moena gel i hoʻohana wale ʻia a i ʻole i hui pū ʻia me nā moena pua hiki ke hoʻoulu i ka haʻalulu liʻiliʻi, akā ʻaʻole e hoʻonāwaliwali ʻia ka haʻalulu i ka halihali ambulance e kekahi hui moena.
I ka lawe ʻana i nā keiki hou haʻahaʻa haʻahaʻa haʻahaʻa, pili paha ka pilikia o ka haʻalulu.
Hōʻike kēia mau ʻike i ka pono e aʻo a hoʻolālā i nā mea hana ʻoi aku ka maikaʻi e hiki ke hōʻemi i ke koʻikoʻi o ka haʻalulu
