The pericardium is a membranous cyst, divided into fiber layer and serous layer, and the serous layer is divided into dirty layer and wall layer. The dirty layer covers the surface of the heart, and the wall layer is attached to the fiber layer, and there is a cavity in the middle called the pericardial cavity. Under normal circumstances,

The wall layer is very smooth, and now the pericardial friction sound represents inflammation. Inflammation will produce exudate and flow into the pericardial cavity. The effusion generated is called pericardial effusion.

When the pericardial effusion increases to a certain amount, separates the viscera and wall layers, and the friction between each other is gone, the pericardial friction sound will disappear. This is why in clinical practice, cases with pericardial friction sounds with a large amount of effusion are rare and special.

, This old lady probably is not. Because after auscultation, the patient's first heart sound and second heart sound are not far away.

If there is no large amount of effusion, the disease has not reached the level of pericardial tamponade, which can be called a blessing.

Xie Wanying put down the stethoscope and then asked the patient about the location and characteristics of the pain in his heart: "Is it painful like a knife cutting, or does it feel like it is hit by a sandbag?"

The old lady said: "It's like being hit in the chest by something heavy."

It was a dull pain. Although myocardial infarction is also dull pain, this pain may come from the pressure pain caused by pericardial effusion. Xie Wanying analyzed and estimated it in her brain through the examination data she has mastered at this stage, and believed that the patient's myocardial infarction might be

The sex is small. The main problem is still a bit acute heart failure.

The flight attendant brought an oxygen mask to the nurse. The nurse changed the oxygen mask to the patient. The flight attendant took advantage of this time to whisper in Xie Wanying's ears.

"The captain asked, do you need to land at a nearby airport in an emergency? If you need it, you should quickly say that we should contact the nearby airport for landing. We also need airport coordination."

The plane does not land immediately if it wants to land. Even if it is temporarily forced to land, it must first be coordinated with the airport. The consequences of collisions are caused by the plane being destroyed and the person being killed.

"How long will it take to continue flying from the Capital Airport?" Xie Wanying asked.

"About an hour." The flight attendant replied.

In this way, the plane is about to fly over the capital. The medical conditions around the capital are incomparable to the capital. And what is even more terrifying is that everyone around knows that the doctors in the capital are running to the capital for medical treatment, which leads to the medical technology around the surrounding areas

Some are far worse than the capital, and some are far away from the capital.

"If you find a nearby airport to land temporarily, how long will it take? It will take more than ten or twenty minutes, right?" Xie Wanying asked again.

"Yes." The flight attendant was surprised at her quick calculation ability, as if she was more than just a doctor.

Ladies don’t know it. Doctors often need to calculate, regardless of internal medicine, surgeons, they have to calculate. What do they think? They have become much older. Every day, they check rounds and orders to calculate the dosage of patients, which is a basic skill of clinicians.

This item has involved calculations. Doctors should try to calculate the specific dose before the patient's changing condition. The more accurate the calculation, the better.

On-site emergency doctors should also estimate the best transportation plan for patients.

Can the patient's condition be waited? Can he wait until an hour later to safely land at the Capital Airport before being sent to the hospital? If so, regardless of the patient or his family, he will definitely choose the Capital Hospital for treatment first.
