以股動脈脈波頻譜推測肺部缺氧：動物實驗

Abstract

Using the non-invasive method to monitor the pulmonary artery pressure in the exercise training program of the chronic obstructive pulmonary disease patients might reduce the incidence of cardiac complication from the pulmonary hypertension and hypoxia. The purpose of this study was to detect the femoral artery pulse pressure and its harmonic changes of the rabbits in the hypoxia status.Ten rabbits underwent the femoral artery catherization for detecting their femoral artery pressure and their harmonics. Ten percent carbon dioxide mixed gas was inhaled to reduce the oxygen saturation of the rabbits from 95 % to 90% or lower. The mean femoral artery pressure, pulse pressure, and its harmonics before and after the hypoxia were recorded and analyzed. The result showed that the mean femoral artery pressure of the rabbits increased from 68.3± 6.2 mm Hg to 73.5±7.1 mm Hg (P= 0.04) when hypoxia and the mean pulse pressure elevated from 8.4 ± 1.2 mm Hg to 13.6 ± 1.1 mm Hg (p=0.0024) with statistically significant difference. Eight of the ten rabbits had transferred their harmonics from the low frequency to high frequency during hypoxia. We concluded that the rabbits mean femoral artery pressure and pulse pressure would rise during hypoxia, and its harmonics may shift from the low frequary to the high frequency.
