Here are some common questions our customers run into when using our products.
Q: Why does only one side of my stethoscope chest piece work?
A: Combination scopes (those equipped with both a diaphragm and bell) are designed to provide a broader frequency response. In a typical combination scope, only one side of the chestpiece is "active" at a time. Rotating the chestpiece around its valve stem selects one side and "deactivates" the other. Hold the tubing with one hand and rotate the stethoscope chest piece until it is clicked into place.
Use the smaller bell for a more focused exploration of sound in a smaller area. The smaller bell also gives more detail by reducing the area covered and shutting out nearby sounds that a larger bell would pick up. Use the smaller bell to distinguish between subtle sounds in specific locations like a cardiologist or other medical staff. Use the other side of the bell (with the diaphragm) to listen to a less focused area inside of the chest cavity.
Q: What size blood pressure cuff do I need?
A: It is very important to use the appropriate size cuff for your arm to obtain accurate measurement results when using your blood pressure monitor. In order to determine the appropriate cuff size, you need to measure the circumference of your arm. You should periodically measure your arm size. This is especially true if you have a borderline arm size measurement, or you may have gained or lost weight.
It is important to ensure the arm cuff you are using with your monitor is the correct size for you. If the incorrect cuff is used the result may be an inaccurate reading and/or the cuff will be damaged (air bladder).
To determine your arm size, use a cloth tape measure and place the tape measure midway between your elbow and your shoulder around the circumference of your upper arm. Wrap the tape measure evenly around your arm. Do not pull the tape tight. Note the precise measurement in centimetres.
Q: Why does my blood pressure cuff open up when pumping?
A: The cuff should be firmly secured but not too tight – just enough so that it is difficult to slide 2 fingers under the cuff. This space is imperative for an accurate reading. Also check the air connections between the bulb / gauge and the cuff. Make sure that there isn't any air leaking when pumping the bulb.
