What is the force of pressure
a typical sample of the work of emergency doctors
in addition to being busy with rescuing and seeing a doctor all day long, Liu Yong, as the director of the emergency department, often thinks about China's current 120
compared with foreign 120 emergency system, China's 120 emergency system is not comparable, "the gap is too big", which is the consensus of many emergency doctors, "China's emergency system still has a lot to do"
the threshold for doctors to enter the emergency system should be raised, and the quality of talents should be guaranteed. This kind of threshold setting is not only reflected in the entrance examination and graation examination, but also should increase the difficulty in the entrance examination“ Of course, the assessment of emergency doctors is not only limited to the level of knowledge, but also the assessment of doctors' moral level. Liu Yong stressed that this kind of moral level is manifested in reverence for life, love for patients and good communication skills for patients
at present, it is a common fault for most hospitals to pay more attention to technical level than humanistic level in selecting emergency doctors
in addition, emergency doctors have to undertake all the first aid work before patients enter the emergency room. As an emergency doctor, every time there is a scene, he just faces the sudden scene by himself. He also needs strong pressure resistance and independent bearing ability
a "cruel" reality is that it is usually difficult to recruit suitable talents in hospital emergency department<
a month ago, Liu Hongmei, head of the personnel department of Beijing Emergency Center, went all over the major job fairs in Beijing and announced the recruitment information to the major networks, media and medical institutions in the city. However, as of June 28, Liu Hongmei had only received 14 resumes
since 2005, the number of undergraate graates recruited by Beijing Emergency Center has been decreasing year by year. This year to catch up with the economic crisis, Liu Hongmei originally thought that the "harvest" would be better, but after the relevant audit proceres, only four people were finally admitted
"it has a lot to do with the treatment of emergency doctors," Liu Yong said. Emergency doctors have high labor intensity, hard working environment, high responsibility risk and limited business development. However, this is not reflected in their salary. On the contrary, in some hospitals, the "status" of emergency doctors is quite low
another reason for most medical students to give up entering the emergency system is the high risk faced by emergency doctors“ It is necessary to establish a fair and scientific evaluation mechanism of medical malpractice. Liu Yong said that the role of this evaluation mechanism lies in "it is necessary to distinguish between the absolute misdiagnosis caused by the limitation of medical technology level and the relative misdiagnosis caused by the personal problems of doctors (such as the medical technology level and attitude of doctors)"
take myocarditis as an example, when an ordinary febrile patient is sent to the emergency room, most doctors will not consider the possibility of "myocarditis". It is understood that the incidence rate of "myocarditis" in febrile patients is 1/10000. "If every fever patient is sent in, they suspect myocarditis. All patients are allowed to perform ECG. The only response of the patient is the doctor's indiscriminate examination."
What if an emergency doctor happens to hit the "one in ten thousand" probability? Is it reasonable to attribute the "one in ten thousand" probability to doctors? Liu Yong said
in addition, for the medical disputes that doctors always encounter, from the perspective of maintaining the normal operation of the hospital and the legitimate rights and interests of doctors, Liu Yong believes that "hospitals should buy medical liability insurance for doctors"
and this proposal has already reached the consensus of the medical community. As early as 2007, in view of the rising trend of violence in hospitals in Guangzhou, which seriously interferes with the normal working order of hospitals, deputies to the Guangzhou Municipal People's Congress suggested that local laws and regulations should be formed as soon as possible and medical liability insurance should be promoted according to the practice of other regions<
under the current framework of solving medical trouble, medical trouble is usually a minor matter, which often ends with huge compensation from hospitals. "Medical liability insurance can recover the economic losses caused by medical treatment as much as possible."
the most important thing is "the government should do something and not do something". Liu Yong said“ When hospitals are violently attacked by some organizations with ulterior motives, such as medical trouble, the government should resolutely suppress them“ When the doctor-patient disputes cross the legal boundary, the inaction of the government and the law enforcement forces can not be explained by any "pains and pains"
and the "Inaction" lies in that the government should hand over the rewards and punishments of doctors, the identification of medical accidents and the settlement of medical disputes to the local medical association, and the government had better not intervene“ Only in this way can the medical disputes be solved peacefully< It is not easy to interview Liu Yong. Not because of the big name, but because he really doesn't have time. On the afternoon of the 6th, when he made an interview appointment with him, he interrupted 39 Health's request in a hurry. The noise from the microphone told me that the emergency department was "busy". Sure enough, Liu Yong politely told me that he was "busy now". Liu Yong was contacted for the second time until 8:36 p.m. at this time, Liu Yong's phone call was still busy. After trying to dial again several times, the author finally called in, but Liu Yong kindly reminded the author, "I'm not busy now. If I'm busy, I can't continue to accept the interview, please forgive me."
instead of taking out the interview outline in a stylized way, I had a casual chat with Liu Yong. This way allows me to capture more details and feel the image of a flesh and blood emergency doctor. This image is not "Gao Daquan" or "resentful wife". Like all doctors who stick to the front line of medical treatment, Liu Yong has a love for this job, a grievance for patients, and a helplessness for current systems. But despite the thorny road, Liu Yong has been in this position for 12 years and said he would choose to continue. The reason is that when he watched the dying lives being dragged back by himself and his colleagues from the hand of death, he was very happy and intoxicated
ring the interview, when it comes to the sense of achievement and the scene of the construction worker's resurrection, Liu Yong felt like yesterday. As for more deeds, Liu Yong said he would not talk more about them, because it is the doctor's "should" to save the dying and heal the wounded. But for the patients who don't understand the doctor, for the scenes of medical trouble, Liu Yong's mood is difficult to calm down. Like the scars on the body, good and rotten, perhaps, this pain will always be
"have you ever complained about medical emergency for 12 years"? There was a long silence over the microphone
"yes, but not for the work itself, but for some patients and their families," said Liu Yong
it's nearly ten o'clock in the night after the interview. When the prosperous city tends to be quiet, when busy people are ready to rest, emergency doctors are waiting for a new call.
Atmospheric pressure calculation: there are usually equilibrium condition method and Newton's law of motion method (the formula is only a rough calculation, and sometimes the measured value is not accurate, everything should be subject to the actual situation)
1. After Torricelli measured the air pressure, people calculated the mass of air per unit area through the formula P = f / s. Then apply the density of the air, calculate the volume, and divide it by the mass to know the distance from the ground to the top of the atmosphere
When the volume of gas, the amount of substance and the absolute temperature are known, the gas pressure can be calculated by the formula PV = NRT (where R is a constant, r = 8.314 PA · m3 / mol · K or r = 0.0814 atmospheric pressure · L / mol · K). There are also deformation formulas PV = MRT / m, P= ρ RT/M3, P = P mercury GH (mercury density * 9.8 * mercury column height = standard atmospheric pressure)
the unit of air pressure is 100 Pa, taking one decimal place; Some also take the millimeter mercury column height as the unit, takes two decimal places. The conversion relationship between mm and HPA is
1 HPA = 0.750069 mm (height of mercury column) ≈ 3 / 4 mm (height of mercury column)
1 mm = 1.333224 HPA ≈ 4 / 3 HPA
the atmospheric pressure observation in China was recorded with MM mercury column height before 1953 and HPA after 1954, It must be converted to the same unit
< H2 > extended data
the most common instruments for measuring air pressure are mercury barometer and empty box barometer. It is also a relatively accurate instrument
three centuries ago, the city of madeburg, Germany, concted an experiment in public. Otto Grick, the mayor and inventor of the ventilator, combined two hollow copper hemispheres with a diameter of 37 cm to make them airtight, and then used the ventilator to extract the air from the copper ball. Four strong horses are tied to the ring of each hemisphere and pulled in the opposite direction at the same time. The two hemispheres cannot be separated
finally, 16 horses were used, and with a loud noise, the copper ball split into two. This is the famous madeburg hemispheric experiment. The experiment shows that air not only has pressure, but also has great pressure. The average surface area of an alt's body is 2 square meters, and the atmospheric pressure on his whole body is 200000 Newton
atmospheric pressure is atmospheric pressure. Air has weight, and pressure is the force that the atmosphere exerts on a unit area. The so-called pressure of a place refers to the total weight of the air column extending vertically upward to the top of the atmosphere per unit area of the place. In meteorology, it is often used as a unit of measurement of air pressure. Specifically, it is stipulated as follows: when the sea level with a temperature of 0 ℃ and a latitude of 45 ℃ is taken as the standard pressure, it is called one atmospheric pressure, and its value is 760 mm mercury column high, or equivalent to 1013.25 HPA
