妊娠改变了通气动力学,当肺功能不全时,危险较大,必须改善通气。在产科监护和帮助持续呼吸情况下,慢性呼吸功能不全者维持继续妊娠是可能的,但较为少见。本文作者报道一例30岁,身高1.54m的慢性肺功能不全的脊柱后凸孕妇,通过家庭式应用鼻面罩吸氧的老方法,以达改善通气目的。在孕34周时行剖宫术,获得一体重2040g的活婴,取得成功,并以此进行讨论。在正常孕妇,随着解剖学改变(支气管充血、胸廓支架扩大、横膈抬高),呼吸功能随之改变,肺活量(VC)恒定,容积增加,后者则减少了呼吸储备量,随之呼吸频数增加,但较缓慢,因此孕 Pregnancy changes the ventilation kinetics, when the lung insufficiency, the greater the danger, we must improve ventilation. It is possible, but less common, to maintain continued pregnancy in obstetric care and to help keep breathing intact. The authors report an example of a 30-year-old 1.54-m-age, pregnant woman with kallikrein who has chronic lung insufficiency through a home-based nasal mask that uses oxygen to improve ventilation. Cesarean section was performed at 34 weeks of gestation to obtain a live birth weight of 2040 g, which was successful and discussed accordingly. In normal pregnant women, respiratory function changes with anatomical changes (bronchial congestion, expansion of the thoracic scaffold, elevation of the diaphragm), a constant volume of vital capacity (VC), and a decrease in respiratory reserve with consequent respiration Frequency increases, but slower, so pregnant
