Pulsatility index ( PI ) tam sim no yog qhov feem ntau siv qhov ntsuas rau kev ntsuas ntawm UtA Doppler cov qauv kev hloov pauv. Txawm li cas los xij, yav dhau los tshaj tawm cov kev tshawb fawb ntawm UtA Doppler kev tshuaj xyuas thoob plaws cev xeeb tub tau siv ntau yam Doppler cov cim 3, 5, 6, 10, 12, 14, 15, 17, 19-22 lossis cov qhab nia system13, 16, 18.
Xav txog qhov no, Pi yog dab tsi thaum cev xeeb tub?

Qhov thib ob, qhov kev ntsuas pulsatility li cas? Lawv pom tias txhais tau tias qhov tseem ceeb ntawm pulsatility index (PI) thiab qhov siab tshaj plaws qhov ntsuas rau cov hlab ntsha ntawm kev cog lus hauv li qub lub sij hawm cev xeeb tub yog 0.48 (SD 0.19) thiab 0.44 (0.18), feem. Thaum lub sij hawm cog lus, qhov txiaj ntsig nruab nrab nce mus rau 1.66 (0.85) thiab 1.46 (0.65), feem.
Qhov thib ob, Pi yog dab tsi hauv ultrasound?
PI = (qhov siab tshaj systolic ntws - ncov diastolic ntws) / (txhais tau tias ntws) Tus neeg teb xov tooj feem ntau lees paub thiab cais tawm qhov siab tshaj (vmax) thiab yam tsawg kawg (vmin) tshaj tawm, thaum lub ntsiab lus tshaj tawm (vmean) tau suav los ntawm ultrasound tshuab.
MCA PI thaum cev xeeb tub yog dab tsi?
Tus me nyuam hauv plab nruab nrab lub paj hlwb ( MCA ) pulsatility qhov ntsuas ( PI ) yog qhov ntsuas tseem ceeb siv hauv kev ntsuas menyuam hauv nruab nrab lub paj hlwb Doppler. Nws tau suav los ntawm kev rho tawm qhov kawg diastolic tshaj tawm (EDV) los ntawm qhov siab tshaj systolic tshaj tawm (PSV) thiab tom qab ntawd faib los ntawm lub sijhawm nruab nrab (nruab nrab) tshaj tawm (TAV):

Rh tsis zoo txhais li cas thaum cev xeeb tub?
Rhesus (Rh) qhov tseem ceeb yog cov protein uas muaj nyob rau ntawm cov qe ntshav liab. Yog tias koj cov ntshav muaj cov protein, koj muaj Rh zoo. Yog tias koj cov ntshav tsis muaj cov protein, koj nyob Rh tsis zoo. Koj cev xeeb tub xav tau kev saib xyuas tshwj xeeb yog tias koj Rh tsis zoo thiab koj tus menyuam yog Rh positive (Rh tsis sib xws)
