国内许多单位已开展应用4F 微型心导管监测肺动脉压力。然而,国产微型心导管内径为0.9毫米,导管长1200毫米,用这种细长的导管测获的肺动脉压力可靠性如何?不少学者对此表示关注。Swan-Ganz 导管是目前国际上公认的,也是国内外应用最多的监测肺动脉压力的导管。为了研究微型心导管测获肺动脉压力的可靠性,我们对7例慢阻肺(COPD)病人,
Many domestic units have carried out the application of 4F microcatheter to monitor pulmonary artery pressure. However, the domestic microcatheter catheter diameter 0.9 mm, catheter length 1200 mm, using this slender catheter measured pulmonary artery pressure reliability? Many scholars expressed concern. Swan-Ganz catheter is currently internationally recognized, but also the most widely used catheter monitoring pulmonary artery pressure. In order to study the reliability of miniature cardiac catheterization of pulmonary artery pressure, we investigated seven COPD patients,
