1, nervous system:
Accepting a certain intensity of vibration will cause discomfort and even unbearable. Vibration will interfere with development, hand-eye coordination, concentration, spatial disorientation, work efficiency, work ability and work efficiency.
2. Cardiovascular system:
Because the sympathetic nerve is in a state of tension, blood pressure increases, pulse pressure increases, heart rate increases, cardiac bleeding decreases, myocardial ischemia, S-T segment of electrocardiogram decreases and so on.
3, respiratory system:
The respiratory movement is enhanced, the oxygen consumption in the body is increased, and the energy metabolism rate is improved. Hyperventilation can lead to hypocapnia.
4. Digestive system:
Gastrointestinal secretion function weakened, loss of appetite. The prevalence of gastroptosis is increasing.
5. Visceral injury:? Strong and violent vibration can lead to visceral displacement or some mechanical damage.
6. Bone and muscle injuries:? Such as driver's low back pain, disc herniation, thoracolumbar degeneration and so on.
7. Impact on women:? Menstrual disorders, increased abortion rate.
8. carsick: (carsick)
Vestibular visceral reflex.
Workers working in vehicles are caused by repeated excessive stimulation of vestibular organs by any form of acceleration (such as bumps, swings or rotations) and vibration acceleration in different directions.
The patient first felt tired, listless and broke out in a cold sweat, and then he felt dizzy, nauseous and vomited. Severe vomiting can lead to electrolyte disorder and even shock.
Some patients were accompanied by blurred vision, decreased blood pressure and nystagmus.
Inducing factors: emotional tension, excessive fatigue, physical weakness, hunger, satiety, poor air in the car, etc.
Treatment: antihistamines: Minkejing and Cheng Yunning. ? Anticholinergic drugs: scopolamine hydrobromide.
