What is a dead finger?

A dead finger, also called a vibrating white finger (VWF), is one of the form of a state known as the hand -arm vibration syndrome in which one or more fingers of the Brno, growing growth and change color due to exposure to electrical instruments or other vibration objects. Many of them are considered a secondary form of Raynaud's phenomenon, a condition characterized by limited blood flow to the limbs. Because the dead finger often affects those who use vibrating tools at work, many countries have tried to regulate the maximum time that a worker can expose to vibrations. At the beginning and at the end of the attack, suffering from armor in the affected fingers can experience. The skin of the affected fingers can also occupy a white, blue or red shade. Attacks can only take a few minutes or more than an hour. In addition, because VWF is progressive condenions, attacks tend to be mild when the condition develops for the first time, growing in severity for months or even years.

Many medical experts consider the dead finger as a secondary form of Raynaud's phenomenon, a condition in which the blood vessels that give the limbs limit abnormally and cause these limbs to rip and dull. In the case of a dead finger, this unusual narrowing of the blood vessels is caused by damage to the blood vessels caused by long -term use of electric tools or other vibration objects. This condition is particularly prevailing for those who work with vibrating tools, such as miners and some factory workers every day. As in most cases, Raynaudov seems that VWF attacks are deteriorating by exposing cold weather.

Although there is no cure for a dead finger, suffering can take steps to limit the attacks. Reducing someone's exposurere to vibrating objects is the most important factor in limiting VWF attacks. In fact, because the dead finger is common with manual workers, the health and security administration of many countries undertook KROKY to protect workers from the condition of limiting the time that vibration tools can be exposed to every day. Furthermore, wearing warm clothing and gloves can reduce the reaction of blood vessels to cold weather and avoid nicotine and caffeine can support healthy circulation.
