INSTRUCTIONS FOR USE

Please read the leaflet before use and keep it for future reference.

INTENDED MEDICAL USE

The Lian® Nano is a medical diagnosis professional device (used by health professionals trained in its use) that measures the pressure exercised by blood on arteries by the auscultatory method (a stethoscope is therefore required).
It accurately measures maximum systolic blood pressure or SBP (resulting from the left ventricle contracting) and minimum diastolic blood pressure or DBP (resulting from ventricles relaxing).

WHAT DOES “BLOOD PRESSURE” MEAN?

Blood pressure is the pressure exercised by blood flow on the walls of arteries. The highest pressure, produced in the arteries by each heart beat, is called “systolic pressure” whereas the lowest is “diastolic pressure”. Blood pressure fluctuates several times a day and can also vary with stress, nutritional factors, physical activity, medicines or diseases.

WHAT IS “NORMAL” BLOOD PRESSURE?

According to the WHO (World Health Organization), normal blood pressure is systolic pressure less than 130mmHg (millimetres of mercury) and diastolic pressure below 90mmHg. However, blood pressure can vary depending on the individual. The WHO classifications table can be found below.

Blood pressure classification in adults (mmHg)

| Systolic blood pressure (mmHg)| And/or| Diastolic blood pressure (mmHg)
---|---|---|---
Optimum| < 120| and| < 80
Normal| 120-129| and/or| 80-84
Upper normal| 130-139| and/or| 85-89
Grade 1 HBP| 140-159| and/or| 90-99
Grade 2 HBP| 160-179| and/or| 100-109
Grade 3 HBP| ≥ 180| and/or| ≥ 110

ESH 2007 Recommendations.

WARNINGS
The warnings in this document highlight conditions or practices which could cause injury, disease or potentially death of a patient.
⚠ Warning: Possible measurement error. Only use the sphygmomanometer cuffs and Lian® Nano accessories from SPENGLER to avoid measurement errors.
⚠ Warning: Risk of inaccurate measurement. Before use, check that all the connection points, the cuff and tube are completely airtight. Excessive leakage can affected measurement.
⚠ Warning: No changes can be made to this equipment as this could affect measurements.

CHOOSE AN CUFF THAT SUITS THE PATIENT’S MORPHOLOGY

SPENGLER is taking on the fight by informing health professionals in using an cuff that suits a patient’s morphology, as the size of the cuff impacts the quality of measurements:
– A too narrow cuff over-estimates blood pressure.
– A too large cuff could under-estimate blood pressure.

Note:
The index marker showing the arterial index on the cuff must be within the range shown on Lian® Nano cuffs.
When the cuff is positioned on the patient’s arm, the “index” marker shown on the cuff must be within the range shown on Lian® Nano cuffs. If the “index” marker or the edge of the marker does not reach this range, we recommend that you see the table below in order to adapt the cuff to a patient’s morphology.

USING THE LIAN® NANO ANEROID SPHYGMOMANOMETER

Steps

• Leave the patient to rest for 5 minutes
• Place the patient in a comfortable position, with legs uncrossed, and the back and arm elevated, ideally without moving or speaking
• Check that the marker index for arterial index is within the range shown on the Lian® Nano cuffs
• Keep the cuff at heart height during measurement
• Keep the pneumatic circuit closed (check the decompression valve)
• Inflate the cuff for an initial SBP estimation (when the blood circulates again, it causes a noticeable beating sound on the stethoscope) until radial pulse disappears (so-called Korotkoff sounds)
• Inflate again to 30mmHg above the estimated SBP
• Deflate by opening the valve at a speed of 2mmHg per second and simultaneously read the blood pressure on the manometer
• Read the SBP for phase I of Korotkoff sounds
• Read the DBP for phase V of Korotkoff sounds (complete disappearance of sounds noted at the stethoscope)
• Measure the heart rate
• Continue decompression until complete purge of the cuff

⚠ Warning: A blood flow stoppage carries risks.

Recommandation:

• Use K5* for adult auscultation
• Use K5 for auscultation of pregnant patients, so long as the sounds are noticeable when the cuff is deflated, in which case the K4 can be used
• Use K4* for auscultation of children between 3 and 12 years.
• See the table describing the phases of Korotkoff sounds.

Environmental specifications:
Operating temperature: +10°C to +40°C
Operating relative humidity: 20% to 85%
Storage temperature: -20°C to +70°C
Relative humidity at storage: 20% to 85%

MAINTENANCE AND MAINTENANCE VERIFICATION

Comply with current regional regulations for the disposal of manual sphygmomanometers or accessories.

Metrological inspection by an approved body
Check accuracy and watertightness:

• At least once every 2 years (manometer)
• At least once per year (cuffs, tube, bulb)
• After each maintenance operation or repair or replacement of removable parts.

Note: In accordance with international and national metrological standards, the operator or the body responsible for maintenance must ensure traceability of benchmark manometer used for calibration.
Note: The manufacturer undertakes to deliver the spare parts replacement following the instructions from the end user.
Removable parts & accessories: Please contact your approved retailer to purchase the parts and accessories below:

• Replacement bulb,
• Tube,
• Cuffs and bladers (all sizes).

CLEANING AND DISINFECTION:

• manometers: wipe clean with a solution of appropriate disinfectant ; rinse with a wet non-woven tissue. Do not immerse.
• cotton or nylon cuffs: wash in machine, water not exceeding 30-35 °C. Important: the cuffs should be fastened during cleaning. Do not dry in machine.
• bladders and tubes: obturate the extremity of the tube with a clamp (included) before washing in mild soapy water or immerse in a disinfectant solution. Rinse thoroughly and dry flat.
