Lung ascultation

How long does a dr takes to examine u if u have any respiratory problem and how do they come to know ifi am a smoker or not?

Alexben23 Its a difficult question to answer. Auscultation is very subjective and depends of the skill and experience of the person auscultating, But in general I would say 5 -10 mins for a good detailed exam. As a rule when auscultating someone there are 8 postilions on their chest ( anterior) and 10 position on the back ( posterior) that the examiner should listen too, as this would cover their entire lungfield because the intensity of the sound can vary depending on the location. Also the examiner should compare the sides i.e. the right and left when auscultating for variations, subtle differences in breath sounds. In addition to these areas it is important to auscultate under the armpits and along the ribs at the side (although a lot of clinicians do not do this in practice),

With regards to smoking a very tell tale sign is the smell of smoke in their hair, often they overlook this fact when trying to conceal other smoke odors with perfume or deodorant or using mouthwash or breath freshers . In addition smokers are more susceptible to throat irritation, a hoarse voice, frequent coughing, and colds. People who are smoking cigarettes will produce more phlegm, and you may notice they are increasingly trying to cough up or void that extra phlegm (although this is not uncommon with a chest infection or persons with an exacerbation of their asthma).

I have omitted signs like yellow stains on their teeth and bad breath as these can be caused by other activities like drinking cola, coffee etc.

Hope this answers your question.
