Blood vessel rupture caused by various reasons may lead to bleeding. If the blood loss is less than 10% of the total blood volume, it can be quickly recovered through self-regulation of the body. If the blood loss is large, reaching 20% of the total blood volume, there will be symptoms such as accelerated pulse and decreased blood pressure; If the blood loss reaches more than 30% of the whole body blood in a short time, it may be life-threatening.
Blood consists of four components: plasma, red blood cells, white blood cells and platelets. Plasma accounts for about 55% of blood and is a mixture of water, sugar, fat, protein, potassium salt and calcium salt. Blood cells make up another 45% of blood.

"One person's donation 1 10,000 ml is not as good as 1 10,000 personal donation 1 ml." Wang Xin realized that his strength was limited, so it was more meaningful to let more people join the blood donation team. At the beginning of 2008, the blood station of Anqing Red Cross Center set up the city's first voluntary blood donation service team, and Wang Xin became one of the first 27 members, from a blood donor to a voluntary blood donor.
Pu Jianming, 66, has donated blood for 20 years. As the first captain of Anqing Volunteer Service Team, he witnessed the growth of Wang Xin. "When it snows heavily, the hospital is in urgent need of platelets. My first thought is the volunteers in the team, but it is inconvenient to travel in snowy days and time is tight. Finally, only Wang Xin came. Our team has grown from more than 20 to more than 70. She has been, has been at the forefront, and has traveled all over the streets, hospitals and schools in Anqing. "
Not only that, Wang Xin also mobilized colleagues and family members around him to participate in voluntary blood donation. The Ministry of Health awarded the "National Donation Bonus Award for Free Blood Donation" to blood donors whose cumulative blood donation exceeded 8,000 ml. Her sister won the prize, and her brother donated more than 4000 ml of blood and won the bronze prize. Wang Xin himself won the "gold medal" three times.
