Respiratory disorders during pregnancy are connected with its physiology. About half of pregnant women suffer from dyspnea on exertion and some 20 % also from dyspnea at rest. Symptoms may intensify in obese patients. Smoking and respiratory disorders influence the well-being of the fetus. This study evaluates respiratory function in pregnant women as assessed by spirometry. The tests were carried out in 54 pregnant women in the 2nd and 3rd trimester. We found reduced values of vital capacity and expiratory reserve volume in all women, which suggests the existence a restrictive respiratory disorder in physiological pregnancy. Smoking seems to cause obstructive disorders; in smoking patients there was a reduction of the Tiffenau ratio. Participation in birth classes had a positive influence on inspiratory capacity. High BMI before pregnancy, excessive weight gain during pregnancy, or age of becoming pregnant did not appreciably influence spirometry results.
怀孕期间的呼吸障碍与妊娠的生理有关。大约一半的孕妇在运动时会出现呼吸困难，约 20%的孕妇在休息时也会出现呼吸困难。肥胖患者的症状可能会加剧。吸烟和呼吸障碍会影响胎儿的健康。本研究通过肺活量测定法评估了孕妇的呼吸功能。测试在 54 名处于妊娠第 2 和第 3 阶段的孕妇中进行。我们发现所有女性的肺活量和呼气储备量都降低了，这表明在生理妊娠中存在限制性呼吸障碍。吸烟似乎会导致阻塞性障碍；在吸烟患者中，Tiffenau 比值降低。参加分娩课程对吸气量有积极影响。怀孕前的 BMI 高、怀孕期间体重增加过多或怀孕年龄都不会显著影响肺活量测定结果。
