诊断学症状教案模板范文英文回答:Diagnosis of Symptoms Lesson Plan Template.Introduction:Hello everyone! Today, I'm going to teach you how to diagnose symptoms. This is an important skill that can help you identify and understand various medical conditions. By the end of this lesson, you will be able to effectively diagnose symptoms and provide appropriate recommendations. Let's get started!1. Understanding Symptoms:To begin with, let's talk about what symptoms are. Symptoms are the physical or mental changes that indicate the presence of a disease or condition. They can vary from person to person and can include things like pain, fatigue,fever, or even changes in appetite or mood.For example, let's say a patient comes to you complaining of a headache. This is a common symptom thatcan be caused by various factors such as stress, dehydration, or even a more serious condition like a migraine or a brain tumor.2. Gathering Information:The next step in diagnosing symptoms is to gather information from the patient. This involves askingquestions about the symptoms, their duration, intensity,and any other accompanying factors. It's important tocreate a comfortable and open environment for the patientto freely express their concerns.For instance, you could ask the patient questions like, "When did the headache start? How long does it usually last? Is there anything that makes it better or worse?" By gathering this information, you can start narrowing downthe possible causes of the symptom.3. Analyzing Symptoms:Once you have gathered all the necessary information,it's time to analyze the symptoms. This involves considering the possible causes based on the patient's description and comparing them to known medical conditions.For example, if the patient's headache is accompanied by nausea and sensitivity to light, it could indicate a migraine. On the other hand, if the headache is persistent and worsens over time, it might be a sign of a more serious condition like a brain tumor.4. Making Recommendations:After analyzing the symptoms, you can make recommendations to the patient. This can include suggesting lifestyle changes, over-the-counter medications, or referring them to a specialist for further evaluation.For instance, if the patient's headache is caused bystress, you could recommend relaxation techniques or stress management strategies. If the headache is severe and persistent, you might refer the patient to a neurologistfor further examination.中文回答:诊断学症状教案模板范文。
第六节发绀学习目的与要求1、掌握:紫绀的概念、分类及临床意义。
2、熟悉:紫绀的发生机理。
3、了解:紫绀的伴随症状及其意义。
学习纲要一、定义:紫绀(cyano sis )又称发绀,指血液中脱氧血红蛋白或异常血红蛋白衍生物(高铁血红蛋白、硫化血红蛋白)增多,皮肤粘膜呈青紫色的现象。
二、发生机制:紫绀是由于血液中脱氧血红蛋白绝对含量增多所致。
只有当某种原因使毛细血管血中脱氧血红蛋白含量增多至50 g /L时可使皮肤粘膜呈青紫色即紫绀。
重度贫血(Hb< 60g/L时),即使有严重缺氧,动脉血氧饱和度明显降低,亦难出现紫绀。
三、临床表现四、伴随症状1•紫绀伴呼吸困难2•紫绀伴杵状指3•紫绀伴意识障碍复习思考题三、选择:1、紫绀(cyano sis ) 1、二、填空: A.1、发绀在、、、等部 B.位易观察。
C.2、当血中咼铁血红蛋白含量达时可出现发绀。
D.发绀较明显,易于观察的部位是:、名词解释:口唇鼻尖甲床巩膜E .颊部D.暴露于空气中,静脉血可转变成鲜红 色2、药物或化学物质中毒所致的高铁血红 蛋白血症,其发绀特点是: E .静脉注射亚甲蓝可使青紫消退(四)简答:1、 试述中心性发绀与周围性发绀鉴别特 点。
2、 试述中心性发绀的分类及原因。
参考答案、名词解释: 紫绀(cyanosis )又称发绀,指血液中脱氧血红蛋白或异常血红蛋白衍生物(高铁血红蛋白、硫化血红蛋白)增多,皮肤粘膜呈青紫色的现象。
紫绀在皮肤较薄、色素较 少及毛细血管丰富的部位,如口唇、鼻尖、颊部、甲床及耳廓等处较明显,且易观察 到。
二、 填空:1、口唇,鼻尖,颊部,甲床,耳廓 2 、30g /L三、 选择: 1、ABCE 2、ACE 四、简答: 1、2、中心性紫绀又分为:①肺性紫绀:由于各种原因引起肺的通气和(或)换气功能 障碍,肺的氧合作用不足,使体循环血中脱氧血红蛋白增多,出现紫绀,常见于各种 严重呼吸系统疾病。
如呼吸道梗阻、重症肺炎、阻塞性肺气肿、肺瘀血、肺水肿、间 质性肺病、大量胸腔积液、气胸及严重胸膜肥厚粘连等;②心性紫绀:由于心脏或大 血管间存在异常通道,部分静脉血未经肺进行氧合作用,直接经异常通道分流混入体 循环动脉血中,使体循环血中脱氧血红蛋白增多,如果分流量超过心输出量的 1/3 时,即可引起紫绀,见于紫绀型先天性心脏病,女口 Fallot 四联症、Eisenmenger 综合 A. 急骤出现 B. 氧疗青紫消失 C. 静脉血为深棕色征等。
发绀(cyanosis)【授课目的和要求】1、了解发绀的发生机制2、掌握发绀的病因和分类【基础知识回顾】呼吸过程有相互衔接并且同时进行的三个环节来完成:1、外呼吸或肺呼吸,包括:肺通气:肺与外界空气之间的气体交换过程。
肺换气:肺泡与肺泡毛细血管血液之间的气体交换过程。
2、气体在血液中的运输(HbO2)3、内呼吸或组织呼吸,即组织换气(血液与组织、细胞之间的气体交换过程)。
血液中的O2主要以HbO2形式运输。
1、当血液流经Po2高的肺部时,Hb与O2结合,形成HbO2;当血液流经Po2低的组织时, HbO2迅速解离,释放O2,成为去氧Hb:2、1gHb可以结合1.34~1.39ml O2100ml血液中,Hb所能结合的最大O2量称为Hb的氧容量,而实际结合的O2量称为Hb的氧含量Hb的氧饱和度= Hb氧含量/Hb氧容量×100%例如:Hb浓度在15g/100ml血液时,Hb的氧容量为:1.34×15=20.1(ml/100ml血液)如Hb的氧含量是20.1ml,则Hb氧饱和度是:20.1/20.1×100%=100%;如Hb的氧含量是15ml,则Hb氧饱和度是:15/20×100%=75%一、定义(definition)发绀是指血液中脱氧血红蛋白(原称还原血红蛋白)增多,使皮肤、粘膜呈现青紫的现象。
广义的发绀,还包括少数由于血液中出现异常血红蛋白衍化物(高铁血红蛋白,硫化血红蛋白)所致的皮肤、粘膜青紫的现象。
还原血红蛋白增多、高铁血红蛋白,硫化血红蛋白→→使血红蛋白失去氧合作用→→导致机体缺氧→→引起发绀观察发绀在皮肤较薄、色素较少、毛细血管丰富的部位,如口唇、鼻尖、面颊和甲床清楚。
二、发生机制(mechanisms)发绀是由于血液中还原血红蛋白的绝对量增加所致。
HbO2呈鲜红色,还原Hb呈紫蓝色。
当毛细血管血液中的还原Hb>50g/L时,皮肤、粘膜呈浅蓝色,导致发绀。
