Shi Jinyu said indifferently: "My police career does not need to rely on the case-solving rate, and the country knows how much gold the cases I have handled." You know, even if there was no case, I would have retired and then enjoyed the same treatment. ”

Guan Zheng nodded and said, "I know you don't care about official positions and false names, but I want to do this, and I want to give you a retirement gift that you can get your hands on." ”

Shi Jinyu said: "You have been a police officer for almost eleven years, and your case-solving rate is almost the same as mine, this is the best retirement gift." Whether this gift is delivered to me or not, I will treat you as my proud disciple, and at the same time, I will unceremoniously regard you as my pride. ”

Guan Zheng smiled slightly and said, "Thank you." ”

Shi Jinyu adjusted his sitting posture and said, "I have one more thing to tell you." Shi Jinyu broke off for a moment and said, "Forget it, don't worry about this matter, wait until you solve the six. I'll tell you about the 28th case. ”

Guan Zheng finally raised the corners of his mouth and said, "You have so much confidence in me?" ”

Shi Jinyu said: "I have confidence in you, but even if the case is not solved, it is not your fault, what do you think?" ”

Guan Zhengzhen felt that his mouth was really following Shi Jinyu, so he smiled and said, "I understand." ”

Shi Jinyu looked at the ECG monitor on Guan Zheng's side and said, "What do you think of this thing?" Teach me, huh? ”

"Speaking of ECG monitors, there are many ways to do it. ECG monitor is a practical precision medical instrument in the hospital, which can monitor the patient's dynamics at the same time. The device has the functions of ECG information collection, storage, intelligent analysis and early warning. And it has the characteristics of accurate monitoring, touch screen control, simple and convenient. It can also be compared with a known setpoint and a device or system that can issue an alarm if there is an exceedance.

The monitor is different from the monitoring diagnostic instrument, it must continuously monitor the physiological parameters of the patient 24 hours a day, detect the change trend, point out the critical situation, and provide the basis for the doctor's emergency treatment and treatment, so as to minimize the complications and achieve the purpose of alleviating and eliminating the condition. In addition to measuring and monitoring physiological parameters, the purpose of the monitor also includes monitoring and processing the condition before and after medication and surgery.

It's simple. That's it, the main display parameters are heart rate, the number of heartbeats per minute. There is a significant individual variation in the heart rate of normal adults at rest, averaging around seventy-five. Heart rate can vary depending on age, gender, and other physiological conditions. In the same person, the heart rate slows down when they are quiet or sleep, and increases when they are exercising or when they are emotional, which can increase or slow down under the influence of certain drugs or neurohumoral factors. People who regularly engage in physical labor and physical activity usually have a slower heart rate. ”

Shi Jinyu carefully observed the number and said, "Wow, your heart is beating fast enough, people are really amazing, as soon as you speak, your heart rate is moving." ”

Guan Zheng was surprised and said: "Of course, as long as I am a living person, he will definitely dial it." ”

Shi Jinyu was like a child seeking knowledge, and said: "I've seen this thing before, but I haven't understood it in detail, but now I really think it's very interesting." You continue. ”

Guan Zheng continued: "The RR displayed on the device is the respiratory rate, and the respiratory rate is the number of times the patient breathes per unit of time. When breathing calmly, it is about 12 to 18, and in the quiet state, it is about 16 to 20, and the breathing movement is even, and the ratio to the pulse rate is one to four. Men and children are predominantly breathing in the abdomen, and women are predominantly breathing in the chest.

In fact, the metabolic process of the human body is a biological oxidation process, and the oxygen required in the metabolic process enters the human blood through the respiratory system, combines with the hemoglobin in the red blood cells to form oxygenated hemoglobin, and then transports it to all parts of the human body's tissue cells.

Whereas, oxygen saturation is the percentage of oxygenated hemoglobin in the blood that is bound by oxygen to the total volume of hemoglobin that can be bound, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of respiratory circulation. Thus, monitoring arterial oxygen saturation can provide an estimate of oxygenation and hemoglobin oxygen-carrying capacity of the lungs. The oxygen saturation of normal human arterial blood is 98 percent, and venous blood is 75 percent. Oxygen saturation is the percentage of oxygenated hemoglobin in the blood that is bound by oxygen to the total volume of hemoglobin that can be bound, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of respiratory circulation. It is an important indicator of the body's oxygen supply, and oxygen saturation less than 90% is set as the standard for hypoxemia.

Significance of monitoring blood oxygen saturation Oxygen is indispensable in life activities, and oxyhemoglobin is formed by the combination of oxygen in the blood and reduced hemoglobin and is transported to tissues throughout the body. The traditional method of measuring blood oxygen saturation is to collect blood from the human body, and then use a blood gas analyzer for electrochemical analysis to measure the partial pressure of oxygen, calculate the blood oxygen saturation, and monitor the oxygenation function and detect hypoxemia early. ”

"The bottom of that is the body temperature, huh?" Shi Jinyu asked.

Guan Zheng nodded and said, "Yes, it looks like I still have a little fever." ”

Shi Jinyu nodded and said, "Yes, so take a good rest, I'll look at this now, if there is a little change in your body, I will know it, see if you dare to deceive me!" ”

Guan Zheng smiled: "Don't dare, don't dare, but you're my father......"

Dr. Tian watched at the door, and his heart was a lot more cheerful, the usual night shift was a nightmare on duty, but today he was very happy on duty.

Dr. Tian thought for a while, took out his mobile phone, and called Tian Yuming.

Tian Yuming was drinking tea leisurely in the office, looking at his son's phone, picking it up and saying, "What are you looking for me?" ”

"I can't call you if I have nothing to do?" Dr. Tian said.

Tian Yuming is not a sensational person, and said: "I'll hang up if it's okay." ”

"Wait a minute!" Doctor Tian suddenly shouted.

Tian Yuming listened to the faint voice on the microphone and said, "If you have something, just say it, don't beat around the bush." ”

Dr. Tian hesitated and said, "Am I your pride?" ”

Tian Yuming was stunned for a moment and said, "You can do better." ”

Dr. Tian was obviously a little disappointed, but Tian Yuming changed his words and said, "But now you are enough to make me proud." ”

Dr. Tian was a little overjoyed and said, "Thank you! Father! ”

Tian Yuming listened to this title, it was really a little strange, the child grew up little by little, but his companionship and education were very little, every time they met, they were fists and kicks, but now this "Dad" is very kind.
