Using the Stethoscope
Using a stethoscope is pretty straight forward. Some Stethoscopes are better that others of course and usually the ones provided by the UK Services are adequate for the job. Use your stethoscope as much as you can when you first start out as a Paramedic as this will benefit you. Pretty soon you will become proficient in it's use.
"Stethoscope Ring Sign" or Dermatographia in Respiratory Distress. An early and reversible sign of systemic distress in Asthmatics and others who are SOB is the skin changes you see when auscultating the chest. As you lift the stethoscope a visible ring or impress is left. This sign corresponds to the present degree of circulatory efficiency in the skin. Considered with other observations and findings it gives a real-time indicator of improvement or adverse change.
Secure Loose Stethoscope Eartips. Those plastic ear tips that come loose on their threads can be secured with a couple of wraps of PTFE tape used by plumbers (cheap; at the DIY stores).
