Obstetricians and gynecologists have analyzed that compared with X-rays, the impact of ultrasound on the human body will be relatively small. For pregnant women, 3-4 ultrasound examinations during pregnancy can generally help to find abnormalities and understand the development of the fetus. However, when pregnant women have abnormal conditions such as bleeding during pregnancy, placenta previa and oligohydramnios, they should be examined by B-ultrasound in time. The radiation power of ultrasonic humidifier is relatively small, and the impact on pregnant women and fetuses should not be too great.
Even so, it is best to pay attention when using ultrasonic humidifier, try to stay away from pregnant women, and don't point at important parts such as the mouth, nose and stomach of pregnant women. At the same time, whether household appliances and other daily necessities have an impact on the human body has not undergone strict animal and human tests like medical supplies, so pregnant women should try to avoid potential risk factors and choose other types of humidifiers to use.
