Nurse Shirley assesses the patient's condition, and s instructions regarding oxygen therapy Shirley: Hi, Mr. Zhao, your oxygen prongs are off your nose. I'll put it back on, OK? You look distressed. The oxygen will make you feel more comfortable Mr. zhao. Shirley: Mr. Zhao, I have connected the oxygen for you. How are you feeling now? Mr zhao Shirley: Mr. Zhao, you are asking about the flow rate of the oxygen, right? Mr zhao Shirley: According to your condition, you will benefit more from oxygen at a low flow rate Mr zhao Shirley: Yes, I have adjusted the flow rate for you. It's 2 liters per minute. Some patients may need 4 liters or even higher, but we usually put COPD patients on 2 liters Mr Zhao Shirley: In the hospital, your doctor must prescribe the rate at which oxygen is delivered. It is very important that you only use the amount that your doctor has prescribed, no more and no less Mr zhao Shirley: There you go Mr zhao
情境模拟：Chapter 3 Unit 2 Dialogue 2 as Mr. Zhao 采用教材：《涉外护理英语情境对话》，刘晨，外语教学与研究出版社 Dialogue 2: COPD Patient’s Oxygen Needs (Mr. Zhao is a COPD patient. Nurse Shirley assesses the patient’s condition, and gives instructions regarding oxygen therapy.) Shirley: Hi, Mr. Zhao, your oxygen prongs are off your nose. I’ll put it back on, OK? You look distressed. The oxygen will make you feel more comfortable. Mr. Zhao: Shirley: Mr. Zhao, I have connected the oxygen for you. How are you feeling now?

Shirley: In normal people the respiratory drive is largely controlled by the level of arbon dioxide in your blood. In other words, we breathe in and out because our brain senses the carbon dioxide level in our blood Mr Zhao Shirley: But in some COPD patients, carbon dioxide no longer affects your respiratory drive. You are left with low levels of oxygen to drive your breathing. Your body has changed Mr Zhao Shirley: Let me explain. A COPD patients brain senses the need to breathe when the oxygen level is low. Thus a high flow of oxygen may send the wrong signal to COPD patients brain, saying there is enough oxygen in my body and there is no need to breathe very hard. The problem is, then carbon dioxide can build up in your body which can alter your body's chemistry and even put you into a coma Mr Zhao. Shirley: So, if the level of oxygen is corrected by too much oxygen therapy, for example if you are given high flow pure oxygen, the respiratory drive may be reduced you may not breathe well, and carbon dioxide can build up in your blood stream and make you confused or even comatose Mr zhao Shirley: So, for most of the COPD patients, the treatment goal is to keep your oxygen at a level that meets your body's need for oxygen. A range of 88-02% on oximetry usually is acceptable Shirley: You're right. Taking too much oxygen sends a message to your brain to slow your breathin Mr zhao Shirley: Yes, because too low an oxygen level may deprive the tissue in your brain and heart of oxygen and result in memory loss or change in your heart Mr zhao

Shirley: So, please do not change the flow rate by yourself, all right? Mr zha Shirley: My pleasure
