Imagine for a moment the year 1800. A doctor is meeting with a patient – most likely in the patient’s home. The patient is complaining about shortness of breath. A cough, a fever. The doctor might check the patient’s pulse or feel their belly, but unlike today, what’s happening inside of the patient’s body is basically unknowable. There’s no MRI. No X-rays. The living body is like a black box that can’t be opened.
The only way for a doctor to figure out what was wrong with a patient was to ask them, and as a result patients’ accounts of their symptoms were seen as diseases in themselves. While today a fever is seen as a symptom of some underlying disease like the flu, back then the fever was essentially regarded as the disease itself.
But in the early 1800s, an invention came along that changed everything. Suddenly the doctor could clearly hear what was happening inside the body. The heart, the lungs, the breath. This revolutionary device was the stethoscope.

Frank, so doctors were very interested in the patient's history. The story of what the symptom was, how long it had been there, how had changed? What made it better? What made it worse? This is doctor Jaclyn dozen
I am a human taller just and,
The historian of Medicine, Queens University Dozen says that, because the patient
story was all the doktor had to go on the symptoms.

He thought about putting his ear right against the patient's breast, but he decided that that would be an appropriate. Shall we took note book netting

He was so impressed by the quality of the sound that he set about, trying to construct the perfect device for listening to the end

He said that he became a shell Andrew Maniac cylinder maniac, because he he was convinced that the instrument mediating between the two bodies of the patient and the doktor in

Started using his new invention to listen to the heart sounds and the breeding sounds of all of the patients in his hospital, and he started to indent words to describe the sounds cause. Nobody. Nobody had heard these sounds before lunch.
The kid invented away to hear the inner workings of the human body, but that wasn't enough by itself. He wanted to connect
the sounds. He was hearing in his patience with what was actually happening, anatomically inside their bodies and how
how do you connect sounds to what's actually happening inside a body you listen to people right before they die
He ran around the board listening to all the patients documenting their symptoms. Listening to the sound thing aid and in connecting them to the discovery he would make at their autopsy when they died. He thought
every abnormal sound he heard with his stethoscope should correspond.

A relatively short period of time line neck made some key discoveries using his stethoscope. For example.
Figured out that when a person has fluid beneath their lungs, they make a sound kind of like a go found idea a sound he called big off any
he also discovered, sounds the tract with the different stages of tuberculosis, the number one killer in Europe, but the time minor problem.

information about disease was under way in the stethoscope was just the beginning, and we got x rays
which do the same thing at the end of the nineteenth century, and now we have cp scanners and MRI than pet skins, and all of these marvellous devices are basically trading upon the same paradigm that the stethoscope brought along that we should be able somehow to image the pathological anatomical abnormalities inside the body to reach the diagnosis when

Physicians often spend half the time staring at a computer screen. The stethoscope provides an important opportunity for intimacy
The stethoscope is still apart.

conversations are still really important in medicine, doktor bomb back says. He thinks that the stethoscope has come to symbolise the patient, but the doktor is there to listen
and whether we are actually listening to their heart or their lungs is probably not that important. But what they really want to know is ever listening to what they say to it.
