Type: Mechanical Blood Pressure Monitor

General Information

The LD Blood Pressure Monitor is a mechanical device used for measuring arterial blood pressure.
It is important to follow the correct measurement procedures to ensure accurate results.

Frequently Asked Questions

Q: Can I use the LD Blood Pressure Monitor without consulting my doctor?
- A: It is recommended to consult your doctor before using the device, especially if you are undergoing specific treatments or taking certain medications. Your doctor can provide guidance on proper usage and interpretation of the measurements.
Q: Can I use the LD Blood Pressure Monitor on my right arm?
- A: Yes, you can use your right arm if measuring on your left arm is difficult. However, please note that the readings may differ slightly between the two arms.
Q: How tight should I wrap the cuff around my arm?
- A: The cuff should fit snugly on your arm without being too tight or too loose. Improper cuff placement may result in inaccurate readings.
Q: Can I measure my blood pressure while standing?
- A: It is recommended to measure your blood pressure in a sitting or lying position. If measuring in a sitting position, ensure that your hand with the cuff is positioned at the level of your heart.

GENERAL INFORMATION

This Instruction Manual is designed to assist the user with safe and effective operation of the Device for the measurement of blood pressure (hereinafter – the “Device”). Use this Device according to the rules described in this Manual. Operate the Device only as intended. Do not use the Device for any other purposes. Read and understand the whole Instruction Manual, in particular «RECOMMENDATIONS ON CORRECT MEASUREMENT».

INDICATIONS FOR USE

The device is designed to measure arterial pressure of human according to Korotkov method. The device is recommended for use under conditions of clinics and hospitals, as well as in household conditions as supplement to medical observation. Pressure is measured by means of auscultation of Korotkov’s tones by stethoscope and by taking readings on manometer.

RECOMMENDATIONS ON CORRECT MEASUREMENTS

Do not use the device without preliminary consultation with Your doctor, if You undergo treatment by hemodialysis or by anticoagulants, antithrombocytes or steroids. Use of device in these cases may cause internal hemorrhage.
For correct measurement you should know that THE BLOOD PRESSURE IS SUBJECT TO SHARP VARIATIONS EVEN WITHIN THE SHORT TIME INTERVALS. The blood pressure depends on many factors. It is usually lower in summer and higher in winter. The blood pressure varies together with the atmospheric pressure, depends on physical loads, emotional excitement, stresses and dietary regime. Drugs, drinking alcohol and smoking produce significant effect. Even the very procedure of blood pressure measurement in a polyclinic sends the blood pressure high in many people, thus, the blood pressure measured at home often differs from the values received in a polyclinic. As the blood pressure tends to rise at low temperatures, make measurements at an indoor temperature (approximately 20°C). If this Device stayed under a low temperature, keep it for at least 1 hour at an indoor temperature before use, otherwise the measurement result may be incorrect. During a day the difference in readings for healthy people may be 30-50 mmHg of systolic pressure and to 10 mmHg of diastolic pressure. The dependence of the blood pressure on various factors is individual for each person. Accordingly, it is recommended to keep a special book with blood pressure records. ONLY A CERTIFIED DOCTOR USING YOUR RECORDS IS CAPABLE TO ANALYZE THE TENDENCY OF YOUR BLOOD PRESSURE VARIATIONS.
At cardiovascular and some other diseases requiring blood pressure monitoring make measurements in the hours fi xed by your attending doctor. REMEMBER THAT THE DIAGNOSTIC AND ANY TREATMENT OF HYPERTENSION MAY BE CONDUCTED ONLY BY A CERTIFIED DOCTOR ON THE BASIS OF BLOOD PRESSURE VALUES OBTAINED BY THIS DOCTOR. TAKING OF DRUGS AND THEIR DOSES SHOULD BE PRESCRIBED ONLY BY YOUR ATTENDING DOCTOR.
KEEP QUIET DURING A MEASUREMENT TO OBTAIN THE ACCURATE VALUES OF YOUR BLOOD PRESSURE WITH THE ELECTRONIC DEVICE. Measure your blood pressure in the calm and comfortable conditions at the indoor temperature. No eating an hour before measurement; no smoking, taking tonic agents, alcohol 1.5-2 hours before measurement.
The accuracy of blood pressure measurement depends on whether the cuff matches the size of your arm. THE CUFF SHOULD NOT BE TOO SMALL OR TOO LARGE.
Wait 3 minutes between measurements for the blood to restore its circulation. However, the persons with prominent atherosclerosis due to considerable loss of vascular elasticity may need to increase the wait time between measurements (10-15 minutes). This also refers to the patients suff ering for long from diabetes. For more accurate determination of blood pressure it is recommended to make a series of 3 consecutive measurements and to use the average value.

CUFF PREPARATION

Little-Doctor-LD-60-Blood-Pressure-Monitor-fig-4

Insert the cuff end for about 5 cm into a metal ring as shown in the fi g. 3 (if cuff is with ring).
Apply the cuff to your left upper arm so that the air tube is directed to your palm (fi g. 4). If the measurement on your left arm is difficult, you may use your right arm. In this case remember that the readings may differ by 5-10 mmHg and even more.
Wrap the cuff around your upper arm so that the bottom of the cuff is approximately 2-3 cm above your elbow. The sign “ARTERY” should be over the arm artery as shown in the fig. 5.
Fix the cuff so that it fi ts tightly to the arm, but see that it is not overtight. Too tight or too free placement of the cuff may give inaccurate readings.
On the fi xed cuff the sign «INDEX» should point to the area «NORMAL» (fig 7). It means that the cuff is chosen correctly and fits the size of your upper arm. If the sign points to the area marked « » or to the left, the cuff is too small and the readings will be higher. If the sign points to the area marked « » or to the right, the cuff is too large and the readings will be lower.
If the arm has a conic form, the cuff should be put on with a spiral movement as shown in the fig. 8.
If the rolled-up sleeve squeezes the arm interfering with free blood flow the Device may give inaccurate figures not corresponding to your actual blood pressure (fig. 9).
Place the stethoscope head so that it was located in depression, somewhat higher than elbow bend (Fig. 4). If You use the device with a built-in stethoscope (for models LD-60 and LD-71A), to reach better auscultation of pulse on full hand, the cuff may be turned round the hand approximately by quarter of circle (60-90˚) in such way that stethoscope head would be positioned on inner side of hand (more close to the body).
Pressure shall be measured in sitting or lying position of human. IN SITTING POSITION WATCH THAT PART OF HAND WITH CUFF WOULD BE LOCATED AT THE LEVEL OF HEART, AND HAND WOULD BE FREELY LOCATED ON THE TABLE AND WOULD NOT MOVE.

MEASUREMENT PROCEDURE

Insert metal tubes of stethoscope into ears. Close air valve on air pump, having turned it clockwise. Squeezing air pump, pump up the cuff , listening to pulse by stethoscope. After You stopped to listen to pulse, pump up the cuff by 30 mm Hg more.
Slowly opening air valve, turning it counterclockwise, bleed down pressure in the cuff . Watch that pressure in the cuff would fall down at speed 2-4 mm Hg per second. This is necessary to get accurate result.
As soon as You hear weak pulse beats, memorize manometer reading. This is Your systolic (upper) arterial pressure.
Pressure in the cuff is continuing falling down at the same speed (2-4 mm Hg per second). You are continuing to listen to pulse. Sounds which You hear will change. Unlike the fi rst beats, they will become softer, resembling rustling. At the moment when You practically stop seize pulse, memorize manometer reading. This is Your diastolic (lower) arterial pressure.
