Inspiratory pressures were measured at three levels in the upper airways and in the oesophagus in different sleeping positions. Thirty one consecutive healthy infants were examined at the age of 1-3 days, 25 of these at 6 weeks, and 23 at 12 weeks. Oxygen saturation, an electrocardiogram, transthoracic impedance, nasal airflow, and inspiratory pressure in the epipharynx, oropharynx, hypopharynx, and in the intrathoracic part of the oesophagus were measured. There was no significant change in the heart rate, oxygen saturation, or respiratory rate in the four sleeping positions. The peak negative inspiratory pressures obtained from the oesophagus (PES) were significantly lower in the supine head straight compared with the supine head turned and the prone positions. At 6 weeks, the only significant difference was between the supine head straight and the prone positions. The PES is less negative at all ages in the supine head straight than in all other sleeping positions, but this does not reach statistical significance.
在不同睡眠姿势下，对上呼吸道和食管的三个水平进行吸气压力测量。对31名连续的健康婴儿进行检查，1 - 3日龄时检查了31名，其中25名在6周时检查，23名在12周时检查。测量了氧饱和度、心电图、经胸阻抗、鼻气流以及上咽部、口咽部、下咽和食管胸内部分的吸气压力。四种睡眠姿势下的心率、氧饱和度或呼吸频率均无显著变化。与仰卧头转向和俯卧位相比，仰卧头伸直位时从食管获得的最大负吸气压力（PES）显著更低。在6周时，唯一显著的差异是仰卧头伸直位和俯卧位之间。在所有年龄段，仰卧头伸直位时的PES负压均低于所有其他睡眠姿势，但这未达到统计学显著性。
