Frequently Asked Questions - LD-80 Little Doctor

How do I take a measurement with the Little Doctor LD-80?

Sit or lie down with your arm at heart level. Wrap the cuff around your left upper arm (2–3 cm above elbow). Insert the stethoscope earpieces, close the air valve, and pump the cuff until the pressure is about 30 mmHg above the point where you no longer hear pulse. Slowly open the valve (2–4 mmHg/s) and listen for Korotkoff sounds. The first sound is the systolic pressure; the point where sounds disappear is the diastolic pressure.

How accurate is the LD-80 blood pressure monitor?

The device has an accuracy of ±3 mmHg for air pressure measurement. For correct readings, follow the measurement guidelines: rest before measurement, use the proper cuff size, and measure at a comfortable room temperature (about 20 °C).

What cuff sizes are included with the LD-80?

The LD-80 includes three cuffs: a newborn cuff (7–12 cm arm circumference), an infant cuff (11–19 cm), and a child cuff (18–26 cm). Additional adult and large adult cuffs are available as accessories.

Can I measure blood pressure on my right arm?

Yes, you can use your right arm, but readings may differ by 5–10 mmHg or more from the left arm. Always note which arm you used and be consistent.

How should I clean the cuff?

Clean the inner surface of the cuff with a cotton ball soaked in a 3% hydrogen peroxide solution. Do not wash or iron the cuff. Avoid using aggressive chemicals.

How long does the LD-80 last?

The device has a service life of 7 years; the pneumatic chamber and air pump have a service life of 3 years. After the warranty period, have the device checked periodically by authorized service centers.

What should I do if the cuff is too tight or too loose?

Ensure the cuff fits snugly but not overtight. The index mark on the cuff should point to the 'NORMAL' zone. If the arm is conical, apply the cuff with a spiral motion. Use a different cuff size if needed.

Why do my blood pressure readings vary throughout the day?

Blood pressure naturally varies due to activity, emotions, temperature, and other factors. Even short intervals show fluctuations. It is recommended to measure at the same time each day and record results for your doctor.

Can I repair the device myself?

No, do not open the manometer. Repairs must only be performed by authorized organizations. Contact Little Doctor or your local service center for any issues.

Is the LD-80 suitable for home use?

Yes, the device is intended for use in clinics, hospitals, and households as a supplement to medical observation. Always consult your doctor before use if you are on anticoagulant therapy or have certain conditions.

GENERAL INFORMATION

This Instruction Manual is designed to assist the user with safe and effective operation of the Device for 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

1. 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.
2. 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 significantly 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.

1. 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.

1. 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.

2. 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.

3. 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 suffering 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

1. Insert the cuff end for about 5 cm into a metal ring as shown in the fig. 3 (if cuff is with ring).

2. 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.

3. 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.

4. Fix the cuff so that it fits tightly to the arm, but see that it is not overtight. Too tight or too free placement of the cuff may give inaccurate readings.

1. Place stethoscope head so that it was located in depression, somewhat higher than elbow bend (Fig. 4). If You use the device with 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).

1. 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

1. 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
2. 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.
3. As soon as You hear weak pulse beats, memorize manometer reading. This is Your systolic (upper) arterial pressure
4. 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 first 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.
