We are on a plane, not on flat ground. We cannot find another doctor or take a taxi to the hospital at any time.
"Sister, you go." Leilei grabbed her mother's hand to prevent her mother from grabbing her sister's clothes. Her sister's words just now made her stronger.
Leilei's mother was furious and could only sit back in her chair. After a while, she looked around curiously like the other passengers on the plane. What kind of patient could this be?
When her daughter was sick just now, no one said they were sick.
Adults have a higher tolerance for illness than children. Especially some hardworking elderly people, they often endure minor illnesses and pains into serious ones, just to avoid worrying their family members. This old lady was almost dying when her daughter who was with her found her.
Walking quickly to the elderly patient, Xie Wanying took a look at the patient and her alarm bells rang. She felt something was wrong just like the nurse.
"Should we let her lie down?" The flight attendant made the same suggestion again, thinking that this time the patient's condition was visibly serious and she should lie flat.
"No, she can't lie down." Xie Wanying and the nurse said in unison.
Patients with heart failure are unable to lie flat. There is a special medical term to describe this special manifestation called orthopnea.

...
To explain this phenomenon, we need to first understand what heart failure is. Heart failure is not an independent disease, but a group of clinical manifestations. Many cardiovascular diseases will present a typical group of symptoms when they develop to a certain extent. The causes of these symptoms have been discovered by medical scientists through research on the physiological structure and function of the human body. They have found that the contraction and relaxation functions of the heart of such patients are impaired compared to normal people. Some have both and some have only one of the two, resulting in a decrease in the venous blood returning to the heart. The professional term is reduced venous return volume. The decrease in venous return volume causes venous blood that cannot return to the heart to stagnate in the human venous system. The blood pumped by the heart to the human arterial system decreases accordingly, showing insufficient arterial perfusion.
According to the principle described above, patients with heart failure have poor heart function. If they lie flat, the normal venous return will increase the burden on the heart, which the patient cannot accept. Therefore, the patient will want to sit up to store the blood returning to the heart in the lower limbs to make his heart feel more comfortable. This is the origin of orthopnea.
It can be seen that edema of both lower limbs is also one of the common symptoms of heart failure patients.
The old lady waved her hand and said there was no need to lie down. It was obvious that she was having difficulty breathing and couldn't lie down. This was a symptom of acute heart failure and orthopnea.
The nurse rolled up the patient's trouser legs to expose the patient's ankles.
If there is edema, the skin around the ankle is thin and medical staff can tell the problem by looking, touching and pressing it.
The strange thing about this old lady was that she was fat, but when the medical staff pressed their fingers on her skin, there were no pressure marks that would normally be seen due to edema.
Lu Xin felt like scratching her head.
Xie Wanying had some idea about the patient's condition, and just by listening to the local accent of the old man's daughter she could confirm certain things.
A province in China is not small in area, and can be compared to a small country in the world. There are differences between different places in the province, and each has its own local accent and customs. For doctors, distinguishing where a patient comes from is not to treat the patient differently, but to help doctors identify whether it is a local epidemic.
Each place has its own epidemic species due to differences in climate, soil, dietary sources, etc.
