"First aid, in fact, is also an art, simple yet not easy," Liu Banxia said after taking a sip of water.

"This also requires a process. Now, can anyone tell me what we should do when we find someone in need of rescue measures? Or what’s the first thing we should do?"

Other students were a bit slower to respond, seemingly considering the question seriously. A few in the front two rows raised their hands enthusiastically, one of whom was Wang Mingxing.

"Alright, let’s exploit a familiar face. Wang Mingxing, you can answer, and to the rest of you whose names I can’t recall, I apologize for not picking you," Liu Banxia said.

Beside him, Qiu Mingyuan jogged over to Wang Mingxing to hand him the microphone.

"Director Liu, I think we should first check the person’s situation?" said Wang Mingxing after taking the microphone.

Liu Banxia smiled and nodded, "Your answer is pretty good, but it belongs to the second step of the entire first aid process. Now, let’s reveal the correct answer: the first thing we need to do is assess whether the surrounding environment is safe."

"If you’ve watched the news recently, you would know about the series of tragic accidents on the highway. The first accident was a rear-end collision, and the damage wasn’t very severe."

"However, because people didn’t follow proper procedures to move to a safe place, it led to second, third, and even fourth accidents."

"When administering first aid to others, this should also be our first action. Because the location where a patient falls ill is not fixed, the scene might be dangerous."

"No matter how handsome or beautiful the person is, we can’t just rush over without caution. It’s too risky; you might end up needing rescue yourself."

"Once the environment is assessed, or the patient has been moved to a safer place, only then should you check the patient’s vital signs."

"For instance, feel the pulse at the neck using your hand, check if there’s breathing at the nose and mouth, or any obstructions. We can also shout loudly for help, in hope of attracting some medical professionals to assist."

"If no one steps in to help, it’s necessary for us to perform first aid. Students in the back might not see it clearly, but performing CPR isn’t about pressing down hard with both hands."

"The correct technique is to use the heel of your hand to compress, with the other hand crossed over on top. Don’t press too hard, as excessive force can break ribs easily."

"But we shouldn’t avoid performing CPR out of concern for this; a high percentage of cardiac arrest survivors experience rib injuries."

"Our resuscitation principle is to compress the chest to make the heart beat. If the force is too weak, it’s ineffective. It’s better to press harder than too lightly."

"Another first aid technique is artificial respiration. Haha, I see people’s eyes light up and knowing smiles appear when this is mentioned."

"My personal judgment is that it’s essential to ensure protection before performing mouth-to-mouth breathing. Don’t be misled by films and TV shows; without accompanying chest compressions, you’re just inflating a balloon."

"Why the need for protection? It’s also about ensuring our personal safety. Some diseases are transmitted through bodily fluids, so this serves as mutual protection for both parties."

"Speaking of films, I have to rant a bit. They’re too sloppy and misleading. For instance, in movies, when a patient has a seizure, they shout to stuff something in the mouth to prevent biting the tongue."

"That’s nonsense, because by the time you find something suitable, the seizure might be over. More daringly, if nothing is found, they suggest putting fingers in the mouth, even if you don’t post it on social media."

"Brave indeed, my friend. If you’re lucky, your finger gets bitten off, or you shatter the patient’s teeth. Off you both go to the hospital together, what a circus."

Students below listened curiously now, because indeed, this is often seen in films. If not fingers, people would offer arms or legs, as if something must be sacrificed.

"During a seizure, muscles exhibit a form of spasm." Liu Banxia continued.

"At this time, we should remove any hard objects nearby, and be cautious near the patient to avoid getting kicked or hit."

"Then, we need to roll the patient to their side to prevent airway obstruction by oral secretions. Otherwise, you’ll have to perform CPR after the seizure."

"Most things seen in movies are just for entertainment; much of it is simplistic. My requirement is that under the premise of ensuring your safety, administer correct first aid."

"Although this issue isn’t examined, we must remember it clearly. In everything we do, safety must come first. Otherwise, you may not rescue the person and instead endanger yourself, adding a burden to subsequent rescues."

"We just covered post-cardiac arrest CPR and not sacrificing fingers or arms for seizure patients. Next, we’ll talk about another small emergency practice in daily life."

"Haha, some of you are smiling again. You’ve probably guessed correctly, it’s the ’Heimlich Maneuver’ for patients with obstructed airways."

"We see this often daily; choking while eating isn’t just a joke. Foods with high viscosity or chunks can accidentally get swallowed and obstruct the airway; this is where we can use this method."

"If you see someone stamping their feet, pounding their chest, occasionally looking up or down, with their mouth agape, and face turning red, it’s likely they’re choking."

"Gently approach from behind, wrap your arms around their waist. Form a fist with one hand, place it just above the navel. Use the other hand to grip your fist, and press forcefully towards your chest."

"However, note that this requires repetition, you shouldn’t continuously press inward. The principle is to use lung air pressure to expel food stuck in the esophagus."

"This method can save others and can be used for self-rescue. When you’re choking, you can’t Heimlich yourself, but you can lean over a chair back or desk edge to apply pressure."

"There’s another important point: though named the ’Heimlich Maneuver,’ caution is required."

"For teenagers or infants, control the force carefully. Otherwise, they might not die choking but from your ’embrace’."

"What I’ve shared today is substantial, I hope everyone can master each item. This way, should similar situations arise, we can save a patient’s life. Now, does anyone have questions?"

"If not, we’ll invite students to group up onto the stage for demonstrations and learning. We’ll also distribute posters with related operations. Han Miao, you may ask, I didn’t expect you to also pass the exam here."

"Dr. Liu, is there anything else we should be cautious of in our daily lives?" asked Han Miao, taking the microphone.

"This is indeed a big question, and there are actually many aspects to be cautious about," Liu Banxia thought for a moment and said.

"Considering the current social environment, I’ll just mention a somewhat sensitive topic that might make some blush."

"With the pressure of university entrance exams gone, we’re now in a more relaxed environment. Many hearts are starting to stir; this is normal due to physiological development at this age."

"But I want to remind everyone to ensure safety. You might not like what I’m going to say next, but it must be said."

"Some statistics indicate a yearly increase in the percentage of HIV carriers among university students. We can’t judge by looks, the only thing to do is ensure maximum protection."

"There are three main modes of transmission: blood, sexual activities, and from mother to child. The extent of harm this disease causes, even without me saying, you surely understand."

"That’s all I’ll say about this topic. Let us proceed with group exercises. Han Miao, take the female students over to Liu Yiqing to study the Heimlich Maneuver. Ha-ha, I bet many were secretly contemplating mischief. No deviating thoughts allowed."

After Liu Banxia finished speaking, he turned off the microphone.

Students below burst into laughter, the previous awkwardness from the sensitive topic disappearing entirely.

"Brother Liu, you really aren’t afraid to say anything, are you?" Qiu Mingyuan moved close to Liu Banxia, handing him another bottle of water.

"It must be said; without a reminder, many of them would remain clueless," Liu Banxia replied.

"If nobody speaks, and I don’t say anything, when will they ever understand? In this aspect, our country’s awareness is still lacking. I’ll make some posters about AIDS later, you can help put them up."

Qiu Mingyuan nodded, being quite a faithful follower of Liu Banxia.

The things Liu Banxia taught today were truly valuable, even though Qiu Mingyuan had participated in first aid, he felt he learned a lot more.

Moreover, he felt the issue of AIDS awareness should indeed be something to focus on; sometimes things get quite chaotic in universities.
