There are a few ways you can use a stethoscope (and cuff) to get vital signs, many of which are simple to obtain but provide a wealth of information. The stethoscope is used to perform auscultation, i.e. listening.
1.) Auscultating the heart-to listen for heart murmurs and extra heart sounds.
2.) Auscultating the lungs-to hear air movement through the lungs
3.)Auscultating blood vessels-to hear for any turbulent flow caused by blockage e.g.atherosclerosis.
4.)Taking a blood pressure.
This is performed by placing the cuff around the arm and inflating it until the radial (wrist) pulse cannot be felt anymore. The value on the manometer is noted, this is a rough estimate of the top (systolic blood pressure). The stethoscope diaphragm (flat part) is placed on the brachial artery just over the elbow joint and inflated until 20mmHg over the original recording.
The cuff is slowly deflated until the first sounds are heard, they will resemble a pulse (a booming noise). NB This is not a pulse, but known as the Korotkoff sounds. The cuff is continuily deflated until the sounds cannot be heard anymore, this is the low (diastolic pressure).
The sounds represent turbulent blood flow through the brachial artery. When the cuff is inflated, the artery is forced shut. When you start to deflate it, blood starts to re enter the artery but is bounced around the very narrow artery, causing the sounds you hear.
When the sounds disappear, that is when the artery has resumed its normal diameter and the blood flow is now laminar (smooth) again.

What vital signs do you need for triage?
* Level of consciousness (ie. Critical/stable/potentially unstable). * Pulse rate. * Breathing rate. * Skin temp. Other vital signs (that can be taken during triage) are: * Breath and heart sounds (with stethoscope). * Blood pressure.

What are the parts of a blood pressure apparatus?
The parts of a blood pressure cuff include several gauges, an inflation ball, rubber tubing, stethoscope and the cuff. A knob is present on the rubber tubing to release pressure. The air released enters a gauge that is read, usually by mercury level, to read blood pressures.
What is blood pressure monitored by?
An inflatable arm cuff with a pressure meter on it and a stethoscope. Although many new automated systems are on the market now.
