When I'm on the night shift, all the department heads can't sleep.

In the afternoon, when the dispatch console sounded, Lin Ye was filing the records from the previous trip.

"Car No. 1, Chengnan Riverside Park, someone has drowned, has been rescued, is conscious, and needs on-site assessment."

Dr. Han accepted the task sheet.

Xu Qing had already packed the oxygen bag and monitor into the first aid kit.

The ambulance drove along the riverbank, surrounded by a crowd of people.

The crowd parted to make way for a young man who was shirtless, soaking wet, sitting on the ground, bent over and coughing.

A strange woman was squatting nearby, holding a pair of soaking wet sneakers in her hand.

"Where are the children?"

The young man caught his breath and looked up.

"The child is fine here, just frightened."

Outside the crowd, a young woman was holding the little girl, who was wrapped in a large towel, her hair was wet, her eyes were red, and she didn't dare to look in their direction.

Dr. Han got out of the car and first looked at the young man sitting on the ground.

He was still conscious, but panting and his body was dripping wet.

"He jumped down to save my child, pushed the child back up, and then his leg cramped up and he sank down."

The woman who was squatting stood up, gripping the shoe in her hand even tighter.

Dr. Han squatted down: "Can you hear me?"

"able."

"What's your name?"

"Liu Yang".

How old are you this year?

"Twenty-four."

Dr. Han turned to the person next to her.

"How long ago were they fished out?"

"They were just pulled out a short while ago."

An elderly fisherman squeezed in carrying an orange lifebuoy.

"I threw a lifebuoy, and two young men went into the water and pulled him out. He was in the water for about four or five minutes."

"What did the person look like when they were pulled from the water?"

"His eyes were closed, and he wasn't responding. We patted his back and made him vomit several times before he recovered."

The old man was gesturing with both hands to indicate the name.

Xu Qing squatted down and clipped Liu Yang's fingers with the finger clips.

Blood oxygen levels are 91 or 92, remaining stable at 91.

"Where do you feel pain right now?"

"I feel tightness in my chest and my throat is uncomfortable."

Dr. Han pressed the stethoscope against his chest: "Take a breath."

Liu Yang did as instructed, and coughed twice more.

After listening to the base of the right lung, Dr. Han handed the stethoscope to Lin Ye.

"Listen, is there any wet rales?"

Lin Ye took it and followed his position to stick it on.

The sound of inhaling was mixed with tiny, intermittent noises, like small bubbles bursting.

"A little."

"A few moist rales." Dr. Han put away his stethoscope. "There's water in the lungs."

"You did a great job, the child is fine. Now it's our turn to look after you, you're a patient yourself now."

"I just choked on a few mouthfuls of water..."

"Your blood oxygen is only 91%, and water has entered your lungs. You seem fine now, but you might not be able to breathe in a few hours. This condition is called secondary drowning, and the more alert a person is, the more careless they are. It's better to come to the hospital with me to get a proper checkup."

"That child..." Liu Yang glanced out of the crowd.

"The child is fine; her aunt is holding her."

The woman held the shoes out to her: "She's only five years old. If it weren't for you..."

"Here are your shoes, I'll hold them for you."

As Liu Yang was being helped onto the stretcher, he turned his head and glanced at the little girl.

"uncle…"

The little girl's voice came from behind the crowd.

"Don't cry, little one, I'm okay."

The ambulance started moving.

Xu Qing connected Liu Yang to the monitoring system and then took his temperature with an ear thermometer: "35.8".

She covered Liu Yang with a warm blanket, and Liu Yang shivered and wrapped the blanket around himself even more tightly.

"That child is only five years old."

Liu Yang looked at the roof of the car and said something.

"I also have a younger sister, who is older than her."

Lin Ye adjusted the oxygen mask and gently placed it over his face.

"Don't talk, breathe more oxygen."

Blood oxygen levels rose to 94.

Lin Ye stared at the monitor without saying a word.

As they exited the park, Liu Yang coughed violently and hunched over.

Lin Ye handed over a tissue, and Liu Yang took it and coughed a few times. The tissue contained light pink phlegm.

"Teacher Han, there's blood in my phlegm, it's pinkish in color."

Early signs of pulmonary edema.

Dr. Han glanced at it.

"Write it down and report it to the hospital."

Lin Ye looked down at his watch and wrote on the record board: "Coughing worsened during the journey, coughing up pink phlegm, blood oxygen fluctuating between 92 and 94."

"Teacher Han, shall I register?"

Report.

Ma Hao picked up the phone and dialed the emergency room of the First Municipal Hospital.

"Emergency room of the First Municipal Hospital, ambulance number one. A 24-year-old male jumped into the river forty minutes ago to save a child who had fallen in. He was rescued after being underwater for four or five minutes. He is currently conscious, breathing rapidly, coughing, and has pinkish sputum. His blood oxygen level is 94, and he is receiving oxygen."

"Vital signs?"

"Heart rate 102, blood pressure 118/72, body temperature 35.8, keeping warm."

Lin Ye looked up at the window, and the driver made a cross.

"We expect to arrive in ten minutes."

"Send him to the emergency room to assess pulmonary edema. If things change en route, call him back immediately."

"receive."

The phone hangs up.

Liu Yang had his eyes closed, but his breathing was still rapid.

"My phone is still on the shore." He opened his eyes and recited a number. "Call my sister for me and tell her I'll be back later."

How old is your sister?

Sixteen years old, in high school.

"I'll call for you, just tell them you'll be back later."

The ambulance turned into the passageway of the First Municipal Hospital.

Lin Ye handed the record board to Ma Hao.

Ma Hao took it and tucked it under his arm. He got out of the car first and followed the emergency bed.

Someone was already waiting outside the emergency room. Liu Yang was wheeled inside, and his colleagues from the emergency room greeted him, their first question being, "How long have you been submerged? What's your blood oxygen level now?"

Dr. Han followed the bed and recounted the time of the fall into the water, the rescue process, the on-site treatment, the coughing up of pink phlegm and the fluctuations in blood oxygen levels during the journey.

Xu Qing put away the monitoring cable and went back to her car.

Liu Yang lay on the emergency bed, his eyes still open, staring at the ceiling.

Dr. Han came out of the emergency room and was about to leave.

At the end of the corridor, the elevator doors opened.

The aunt was carrying the little girl, with the child's mother following beside her, as they jogged over.

"Doctor, where's the young man who saved the person?"

The woman was panting heavily from running.

"She's in the emergency room, undergoing examination. Don't go in yet."

The little girl turned her head from her aunt's arms and peered into the closed door of the emergency room.

Lin Ye squatted down and looked at the little girl.

"Your uncle is inside, he's fine. You can go in to see him after the check-up."

The little girl nodded, buried her face in her aunt's shoulder, then looked up and gazed toward the door.

Lin Ye stood up and added, "The child also choked on water. Keep a close eye on her tonight. If her cough worsens or she has trouble breathing, take her to the hospital immediately."

The woman nodded, then, as if remembering something, took a cell phone out of her pocket.

"Oh, by the way, this is his phone. Please take it to him."

"I'll hand it over to him later."

Dr. Han greeted Lin Ye and Ma Hao.

"Let's go, let's go back."

Lin Ye glanced at the emergency room and then walked out.

As he passed the elevator, he turned around and saw the little girl still clinging to her aunt's shoulder, her eyes fixed on the closed door.

Lin Ye withdrew his gaze and followed Dr. Han.
