The bell or diaphragm of a stethoscope should be used during a physical examination to listen to different frequencies of sounds. The bell is used for low-frequency sounds like heart murmurs, while the diaphragm is used for high-frequency sounds like breath sounds.
A bell is used to listen to low-pitched sounds like heart murmurs, while a diaphragm is used to listen to high-pitched sounds like breath sounds. Use the bell for heart and vascular sounds, and the diaphragm for lung and bowel sounds during a physical examination.
Heart sounds originate from the closure of heart valves during the cardiac cycle. The first heart sound (S1) is produced by the closure of the mitral and tricuspid valves, while the second heart sound (S2) is caused by the closure of the aortic and pulmonary valves. These sounds can be heard using a stethoscope during a physical examination.
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
The diaphragm is connected to circulation through the phrenic nerves, which control the contractions of the diaphragm muscle. When the diaphragm contracts during inhalation, it creates a negative pressure in the chest cavity, allowing the lungs to expand and draw in air, which helps with oxygenation of the blood.
Yes, in its relaxed state, the diaphragm is dome-shaped. When it contracts during breathing, it flattens out to expand the chest cavity and facilitate inhalation.

"The doctor used the stethoscope on the patient to try and hear his heartbeat and breathing patterns."
A murmur can be heard in a valve when there is turbulent blood flow across the valve due to narrowing (stenosis) or leaking (regurgitation) of the valve. This turbulent flow creates abnormal sounds that can be heard with a stethoscope during a physical examination.
Detection often occurs by chance during a routine physical examination.
Systematic practice of inspection, palpation, percussion and auscultation is required as instructed by medical teacher and in Hutchison's manual of Clinical Examination. A mind that doesn't know can't see so you have to know what to look for in physical examination.
the diaphragm valve was developed during the 1940s.

To diagnose pneumothorax, it is necessary for the health care provider to listen to the chest (auscultation) during a physical examination
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.Also, when you inhale, it contracts. When you exhale, it relaxes.
exhalation
When the lungs are expanded, this action takes place due to the diaphragm contracting during inhalation. During exhalation, the diaphragm relaxes.
In a physical examination during inspection there may be a scaphoid abdomen. This refers to a tense abdomen as seen in cases of peritonitis.
