Breath sounds have long been important indicators of respiratory health and disease. Acoustical
monitoring of respiratory sounds has been used by researchers for various diagnostic purposes.
A few decades ago, physicians relied on their hearing to detect any symptomatic signs in
respiratory sounds of their patients. However, with the aid of computer technology and digital
signal processing techniques in recent years, breath sound analysis has drawn much attention
because of its diagnostic capabilities.

Nếu các bạn đọc các sách triệu chứng bằng tiếng Anh, các bạn sẽ thấy một điều là hầu như các tác giả không dùng thuật ngữ “rale” để mô tả dấu hiệu lâm sàng khi khám phổi. Thay vào đó, họ dùng các thuật ngữ như breath sounds, wheezes và crackles. Điều này khiến cho nhiều bạn sinh viên y khoa cảm thấy bối rối khi học sách triệu chứng tiếng Việt và tham khảo thêm sách tiếng Anh.
Physical Findings Patients with pneumococcal pneumonia usually appear ill and have a grayish, anxious appearance that differs from that of persons with viral or mycoplasmal pneumonia. Temperature, pulse, and respiratory rate are typically elevated. Elderly patients may have only a slight temperature elevation or may be afebrile. Hypothermia may be documented instead of fever and is associated with increased morbidity and mortality. Pleuritic chest pain may cause diminished respiratory excursion (splinting) on the affected side.
A truly noninvasive medical measurement is any measurement system that does not
physically breach the skin or enter the body deeply through an external orifice. Thus,
the measurement of body temperature with a thermometer in the mouth, rectum, or
ear canal is considered noninvasive, as is the use of an otoscope to examine the
outer surface of the eardrum. Similarly, the opthalmoscope and the slit lamp, which
shine light in the eyes to examine the retina and the cornea and lens, respectively,
are considered noninvasive procedures....
Five months out from Earth, we were half-way to Saturn and three-quarters
of the way to murder. At least, I was. I was sick of the feuding, the
worries and the pettiness of the other nineteen aboard. My stomach
heaved at the bad food, the eternal smell of people, and the constant
sound of nagging and complaints. For ten lead pennies, I'd have gotten
out into space and tried walking back to Earth. Sometimes I thought
about doing it without the pennies.
I stood as a man might stand who sees a vision, hardly breath-
ing. I made no sound, yet she turned and saw me, sheltered as I
was by the dappled trunk of a tall plane-tree. It was as if I had
called, and she had answered.
I knew she remembered me, and that she did not misunder-
stand my presence. There was no anger in her face, only surprise,
and a light which was hidden as she dropped her head, and passed
on through the gate.
I could have sung the song of the stars. She had not forgotten
me since the afternoon. The look in my eyes...
Lindsay woke on Thursday morning to the sound of Cordelia pulling the curtains open. 'Look at this view!' she exclaimed. All Lindsay could see was a square of grey sky. 'Do I have to?' she groaned crossly. 'What time is it?' 'Half-past seven. I'm going for a run.' Already she was dressed in the familiar training shoes and track suit. It occurred to Lindsay in her jaundiced frame of mind that Cordelia was certainly fit enough to have sprinted to the music department, garrotted Lorna and sprinted back again without even being out of breath, Cordelia added, I'll be...
