四川大学华西医院主任医师万智介绍，"掐人中""喂水"等方法都不是科学的急救方法，部分操作还可能 加重病情。 其中"掐人中"可能因为强烈的疼痛刺激，导致患者暂时唤醒，但是无法解决根本性的晕厥原因，而且用 力过度可能还会导致皮肤和软组织的损伤；而晕厥的时候，患者的吞咽反射是减弱的，这时候喂水可能 导致呛咳、误吸甚至引发肺炎或者窒息。 晕厥的四个常见原因 万智介绍，晕厥是突然发生的、短暂的意识丧失的状态，一般在持续数秒至数分钟后可能自行缓解，但 是它和我们平时说的头晕、头昏、眩晕和昏迷不是同一个概念。 晕厥常见的原因有四个。一是比较常见的体位性低血压，它常见于久蹲后站起来、脱水或不当使用降压 药的情况下，因血容量相对不足，加之发生体位的变化，导致血压可能无法及时调节从而引起的脑缺 血。 二是神经反射异常导致的晕厥。在情绪激动、恐惧、紧张造成的过度换气，或者剧烈疼痛、长时间站立 以及排尿等等这样一些刺激下引发血管扩张或者心率减慢，可能导致脑部供血的骤减。 三是心源性因素，如心律失常、冠心病等导致的晕厥。 四是神经源性因素，比如短暂性脑缺血发作或者癫痫等等，这些都是导致晕厥的常见原因。 见有人晕倒，大家马上一拥而上掐人 ...

Core Viewpoint - The article highlights the critical importance of timely CPR (Cardiopulmonary Resuscitation) training and public awareness in saving lives during cardiac arrest situations, emphasizing the need for broader CPR education in China [1][2][3]. Group 1: CPR Awareness and Training - The survival rate for cardiac arrest in China is alarmingly low, with only about 1% of patients successfully rescued, highlighting the urgent need for increased CPR training among the public [1][2]. - In developed countries, CPR training rates range from 30% to 80%, while in China, it is only between 1% and 3%, indicating a significant gap in emergency response capabilities [2][3]. - Current CPR training efforts in China face challenges such as inconsistent standards, varying quality, and lack of regular mechanisms, resulting in many individuals not mastering CPR techniques [3]. Group 2: Importance of Immediate Response - The "golden 4 minutes" is a critical window for effective CPR, during which bystanders' intervention can significantly increase survival chances before professional help arrives [1][2]. - The article recounts a specific incident where timely CPR by bystanders and medical professionals led to the successful resuscitation of an elderly man, underscoring the life-saving potential of immediate action [1]. - The need for a cultural shift in recognizing CPR as an essential life skill is emphasized, suggesting that emergency response training should be made a standard requirement, similar to practices in Germany and Japan [3].

Core Points - The article emphasizes the critical importance of immediate action in the event of cardiac arrest, stating that every minute of delay can reduce survival rates by 10% [1] Group 1: CPR Operation Key Points - Ensure safety by quickly assessing the environment for risks such as electric shock, fire, falling objects, or traffic [2] - Identify symptoms by checking for responsiveness and breathing; if unresponsive and not breathing, cardiac arrest may be suspected [2] - Immediately call for help and dial emergency services while following dispatcher instructions [2] - Perform chest compressions on a firm surface, ensuring a depth of at least 5 cm and a rate of at least 100 compressions per minute [2] - Open the airway after 30 compressions by checking for obstructions and using the head-tilt, chin-lift method [2][3] - Administer artificial respiration by pinching the nose and sealing the mouth, delivering two breaths while observing chest rise [3] - Use an AED if available, following voice prompts, and continue CPR until professional help arrives or the patient shows signs of recovery [4] Group 2: Common Misconceptions about CPR - Misconception 1: Non-medical personnel are legally restricted from providing aid; however, the law protects those who voluntarily assist in emergencies [5] - Misconception 2: Inadequate knowledge prevents effective CPR; any attempt at CPR is better than doing nothing [6] - Misconception 3: Concerns about causing injury; while rib fractures may occur, the benefits of effective CPR far outweigh the risks [7] - Misconception 4: Waiting for an ambulance is acceptable; the first four minutes are critical, and immediate action is necessary [8] - Misconception 5: Reluctance to perform artificial respiration; chest compressions alone are also effective [9]

Group 3: Broader Implications of First Aid Training - The concept of "everyone learning first aid" reflects a collective value of community responsibility, where individuals are encouraged to care for the safety of others [5]. - The ability to perform first aid can significantly impact survival rates in emergencies, as many cardiac arrests occur outside of hospitals, highlighting the critical role of bystanders [3].

Core Viewpoint - The article emphasizes the increasing prevalence of sudden cardiac death in China, highlighting the importance of awareness, prevention, and timely intervention in saving lives [1][2]. Group 1: Sudden Cardiac Death - The crude incidence rate of acute myocardial infarction among residents aged 18 and above in China is reported to be 79.7 per 100,000 [1]. - Sudden cardiac death is defined as unexpected death due to cardiac causes, typically occurring within one hour of symptom onset, with common triggers including myocardial infarction and arrhythmias [2]. Group 2: Emergency Response - The "golden time" for resuscitation after cardiac arrest is within 4 minutes, as failure to act promptly can lead to irreversible brain damage and multi-organ failure [2]. - Initiatives like the "4-minute rescue circle" in Dongguan and plans to increase AED availability in public places are being implemented to enhance emergency response [3]. Group 3: Risk Factors - Key risk factors for sudden cardiac death include a history of coronary heart disease, hypertension, diabetes, and lifestyle factors such as lack of sleep and high-stress levels [4]. - Individuals with a family history of cardiovascular diseases should undergo regular screenings, including ECG and echocardiograms [4]. Group 4: Prevention Strategies - Lifestyle changes are crucial for heart health, including a balanced diet low in salt, fat, and sugar, regular exercise, and avoiding smoking and excessive alcohol consumption [6]. - External factors like extreme cold weather and high altitudes can increase the risk of sudden cardiac death, particularly for those with pre-existing conditions [6].
