Measurement Procedures

7.As the cuff deflates, listen carefully with the stethoscope for your pulse beat. The first sound represents the Systolic reading and the last sound represents your Diastolic reading.

NOTE: If you make a mistake do not reinflate the cuff. Release all the air. Wait 1 minute. Start again. Waiting allows the engorged blood vessels to return to normal. If you want to take successive readings, wait 5-10 minutes. Waiting allows the engorged blood vessels to return to normal. You may require more rest time between measurements depending on your health.

Care And Maintenance

To protect your unit from damage, please AVOID washing or moistening the cuff or dropping the gauge.

When the cuff is fully deflated, the gauge needle stays within the zero box. If the needle points outside of the zero box, the gauge gives inaccurate readings.

Your new blood pressure unit has been carefully checked to assure reliability and accuracy prior to shipment and use. However, as with any sensitive instrument subjected to repeated use, we recommend that your blood pressure gauge be checked yearly by a medical professional for proper calibration.
