    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">为何</span>左心功能不全会<span style="color: black;">显现</span>夜间自发性憋气（医学术语叫夜间阵发性呼吸困难）？这是<span style="color: black;">因为</span>当左边心脏<span style="color: black;">因为</span>某种<span style="color: black;">原由</span><span style="color: black;">显现</span>了功能<span style="color: black;">衰退</span>，<span style="color: black;">引起</span>左边心脏射血能力降低，射出的血量减少了。<span style="color: black;">那样</span><span style="color: black;">因为</span>心功能<span style="color: black;">衰退</span><span style="color: black;">无</span>射出的血淤存在哪里呢？与左边心脏相连接的是肺动脉（肺动脉、肺部毛细血管床、肺静脉为肺部血管），<span style="color: black;">因此</span><span style="color: black;">无</span>射出的血淤留肺部的血管床，这<span style="color: black;">便是</span><span style="color: black;">咱们</span><span style="color: black;">一般</span>所说的左心衰<span style="color: black;">诱发</span>了肺淤血，<span style="color: black;">因为</span>肺部淤血，肺部血氧交换相对受阻，加上人在<span style="color: black;">睡觉</span>中，迷走神经的张力<span style="color: black;">升高</span>，小支气管较<span style="color: black;">白日</span><span style="color: black;">处在</span>收缩状态，肺活量<span style="color: black;">亦</span>减少，人的横膈肌<span style="color: black;">亦</span>抬高，<span style="color: black;">引起</span>肺部淤血进一步加重，就<span style="color: black;">显现</span>憋气要坐起来的<span style="color: black;">状况</span>。</span></p>
