Why do doctors ask his patients to inhale and exhale their breath previously examining their heartbeat?
Most do it to listen to the quality and nouns of the lungs also. Some doctors do it because is can help the lenient to take a flawless breathe, sometimes the patient is afraid and will hold their breathe when the doctor listens to their heart. This give them a big good breathe wide breathe right before!
I other figured it be because they were listen to your breathing too. Making sure your lungs are in polite working order.
They are listen to your lungs
First, not all doctors are men ... lol; second, listen for different heart sounds is made more difficult when patients are breathing -- some of the sounds we listen for are of very low intensity and frequency.
Deep breathing 3 or 4 times diverts the attentiom of the long-suffering and relaxes him. Heart rate becomes steady,and cardiac and respiratory sounds are okay heard.
uh- they are checking breathing and making sure within is no liquid or mucous or curious noise contained by your breathing.
Some doctors listen to the heart before listen to the lungs. It all depends on how the doctor prefers to do his/her exam.
