What is Blood Pressure?

In the most basic sense, blood pressure is a way of measuring how much force is being exerted on the walls of your blood vessels as blood flows through them.

Systolic blood pressure (the upper number on the blood pressure monitor) is the highest pressure in blood vessels when the heart contracts/beats.

Diastolic blood pressure (the lower number on the blood pressure monitor) is the lowest pressure in blood vessels in between heartbeats when the heart muscle relaxes.

What is Hypertension (High Blood Pressure)?

Hypertension occurs when the systolic blood pressure is equal to/greater than 135 mmHg & the diastolic blood pressure is equal to/greater than 80 mmHg. If left uncontrolled, hypertension can cause heart attack, stroke, dementia, kidney failure, vision loss amongst the serious consequences.

Is it normal for my blood pressure to vary?

Yes, it is quite normal for people’s blood pressure to change throughout the day & night, or in different settings where you may measure your blood pressure. Many things, such as stress levels, food or drink intake, activity levels, even time of day can all affect a person’s blood pressure reading at any given time. In fact, there are published studies that show a given person’s blood pressure can change by up to 20mm within a day, based on activity levels, food/drink intake, stress, etc. This is why it is important to take your blood pressure on a regular basis, & review the overall trend of your blood pressure readings with your doctor.

One should not be too concerned about one single measurement. It is important to take measurements every day at the same time & to know one’s own BP trend, as BP continually changes throughout the day due to the daily fluctuation cycle & many other factors.

When is the optimal time to measure blood pressure?

It is optimal to measure blood pressure within 1 hour after you get up in the morning & before you go to bed at night.

If you measure your blood pressure in the morning, take the measurement within 1 hour after you get up; before having breakfast & after visiting the restroom, rest for 1-2 minutes & then take the measurement in a sitting position.
If you measure your blood pressure at night, after resting for 1-2 minutes, take the measurement in a sitting position before you go to bed.

It is recommended to take the measurement at the same time period every day.

Will I see differences between my readings at home compared to readings in my doctor's office?

Yes, you will see some differences. This is normal & can occur for many reasons. Some of the more common reasons are:

  1. A person’s blood pressure varies throughout the day, so at any given moment your blood pressure can change.
  2. In terms of the amount of change; there are published studies that show a given person’s blood pressure can change by up to 20 mm within a day, based on activity levels, food/drink intake, stress, etc.
  3. You may have a condition known as “White Coat Hypertension.” This is a condition in which a blood person’s blood pressure rises above its usual level when it is measured in a doctor’s office or clinical setting.
  4. You may have a condition known as “Masked Hypertension.” This is a situation in which a person’s blood pressure falls below its usual level when it measure in a doctor’s office or clinical setting.

So do not be alarmed when you see differences between your readings at home compared to your readings in your doctor’s office. Discuss it with your doctor to get the best overall picture of your heart health.

How do I measure my blood pressure correctly?

  1. Sit quietly for about 5 minutes with both feet flat on the floor.
  2. Do not smoke, bathe, drink caffeinated drinks/alcohol or exercise 30 minutes before measurement
  3. Measure at the same time every day
  4. Take multiple readings & record the results using a diary or an app

Which number is more important? (Systolic/Diastolic Blood Pressure)

Both readings are important. Systolic blood pressure measures your blood pressure during a heart contraction & the other measures blood pressure between heart contractions. Usually, more attention is given to systolic blood pressure, as it indicates a major risk factor for cardiovascular disease. For your particular situation, you should discuss both measurement results with your doctor.

Why is it important to monitor blood pressure at home?

Monitoring blood pressure at home has been found useful in helping to monitor the effects of hypertension drugs, as well as detecting masked hypertension & symptoms that are hard to be found otherwise. For these & other reasons, medical organizations around the world now stress the importance of home blood pressure monitoring.

What is the difference between monitoring blood pressure using a home digital monitor as opposed to getting my reading when I see my doctor?

Digital monitors measure blood pressure oscillometrically rather than by auscultation. In auscultation, stethoscopes are used to take blood pressure by listening for specific heartbeat sounds which the doctor then uses to determine systolic & diastolic pressures. Oscillometric technology measures the vibration of blood traveling through the arteries & converts the movement into digital readings.
Omron digital blood pressure monitors use the oscillometric method of blood pressure measurement. An oscillometric monitor does not need a stethoscope so the monitor is simple to use.
It is also important to note that home blood pressure monitoring allows you to monitor frequently & share the results with your doctor if you desire.

What does oscillometric technology used by home digital monitors mean?

Oscillometric technology measures the vibration of blood traveling through the arteries & converts the movement into digital readings.
Omron digital blood pressure monitors use the oscillometric method of blood pressure measurement. An oscillometric monitor does not need a stethoscope so the monitor is simple to use.

Which blood pressure monitor- upper arm or wrist should I purchase?

In terms of which type of blood pressure monitor is best for you, we recommend that you discuss this with your doctor, based on your individual needs.

Upper arm blood pressure monitors are recommended for people who buy a blood pressure monitor for the first time or people who have high blood pressure & need to control it.

Click below to find out more about Omron’s line of upper arm & wrist home blood pressure monitors.

Are digital blood pressure monitors accurate?

All Omron blood pressure monitors are clinically proven accurate. They are clinically validated to be within the following:

  • Blood pressure: within +/- 3 mmHg or 2 percent
  • Pulse: within +/- 5 percent of reading

This meets or exceeds the AAMI (Association of Medical Instrumentation) standards. To understand the accuracy levels of other manufacturer’s blood pressure monitors, you need to contact them. It is always important to investigate accuracy & ease of use before purchasing a home blood pressure monitor.

How often should I send my Omron blood pressure monitor for checking?

The accuracy of Omron blood pressure monitor has been carefully tested & is designed for a long service life. It is generally recommended to have the unit checked every two years to ensure correct functioning & accuracy. Please consult your local Omron representative for the check.

What is a nebulizer?

A nebulizer is a drug delivery machine which converts liquid medicine into aerosol droplets that can easily be inhaled through a mouthpiece or mask.

Nebulizers are primarily used in the treatment of asthma, COPD, and other breathing problems. However, it is also used for severe cases of nasal and chest congestion as it provides immediate relief by the opening of airways.
Reference: Boe J et al (2001). European Respiratory Society Guidelines on the use of nebulizers. Eur Respir J. 18(1):228-42.

Can distilled water or purified water be used for nebulization?

Distilled water or purified water cannot be used alone as a drug solution for nebulization.

What are the key features of a nebulizer?

Key Features Of A Nebulizer

1. Median Mass Aerodynamic Diameter (MMAD µm)

Nebulizers create aerosol droplets with a range of particle size diameters, and MMAD is the diameter that divides the mass of an aerosol in half . MMAD is one of the recommended parameter from European Respiratory Society for measuring nebulizer performance.

Upper Airways:

Chronic – Allergic Rhinitis (Hay Fever)

Infections – Rhinitis (Common Cold), Sinusitis, Laryngitis 

Lower Airways

Chronic – Asthma, COPD

Infections – Bronchitis, Bronchiolitis, Pneumonia

2. Speed

Higher nebulization rate = Shorter treatment time

Nebulization rate is the amount of nebulized medication in ml coming out of the nebulizer per minute.

3. Aerosol Output

Amount of medication deposited in the lungs. It is measured using a breath simulator pump connected to a filter (chemical analysis of NaF in the filter)

It is a key parameter of Nebulizer efficiency.

4. Noise Level

Babies and children may be fearful of the noise generated by compressor type nebulizers therefore a mesh or ultrasonic nebulizer may be more ideal.

5. Portability

Recommended for cases where on the go treatment is needed.

What to look for when choosing a nebulizer?

1. Who will be using the nebulizer?

Adults or Babies or Children

2. What is the condition?

Upper Airways or Lower Airways
Depending on the treatment area, the nebulizer should produce partical size to reach the targeted organ.

3. Where will the nebulizer be used?

At Home or On-The-Go
Compact and lighter nebulizers make it easy to have discreet treatments anywhere.

Common misconceptions about nebulizers

Common Misconceptions About Nebulizers

#1 The Bigger And/Or Louder The Nebulizer, The More Powerful It Is.

The size and the noise level of the nebulizers are dependent on the technology it was developed with. According to the European Respiratory Society (ERS) guidelines, particle size, aerosol output and aerosol output rate are the key performance indicators.

#2 The More Mist Produced, The More Effective The Treatment.

Visibility of the aerosol produced is dependent on the particle size. Higher mist visibility suggests larger particle size, which is suitable for upper airway treatment. Whereas, most asthma medication targets the lower airways. Look for nebulizers that produce the right sized particles (MMAD) for the most effective treatment.

#3 One Nebulizer Can Treat Both Airways

Not every nebulizer comes with the capability to target both airways. Some nebulizer models have the added feature to adjust the particle size produced. Select your nebulizer based on your target treatment area.

What is normal body temperature?

Normal body temperature is in the range of 36.5–37.5 °C on the average, although it varies somewhat among individuals (gender, age). Additionally, temperature can vary according to physical activities, throughout the day, & due to external factors, e.g. with the change of seasons. Normal body temperature may change during any given day. It is usually highest in the evening. Body temperature is typically elevated after physical activity.

Body temperature is a basic condition for the proper operation of the cells. It is configured by many internal organs with the control of the nervous system on the delicate balance of heat production & heat loss. This mechanism (called thermoregulation) ensures the stable operation of vital functions by keeping the body at optimum operating internal temperature.

What is my normal temperature?

Normal temperature varies with the individual & also changes depending on the time through the day.

To find out one's normal temperature, therefore we recommend performing regular measurements under the following conditions:

  • Measure with the same thermometer
  • Measure at the same area
  • Measure at the same time of day

Click here to find out more about Omron’s range of thermometers.

Does the temperature reading depend on the body part where the reading is taken?

Yes! The most accurate optimal values derive from rectal measurement: 37.0-37.5 °C (98.6-99.5 °F), while oral measurement produces slightly lower results: 36.8° ± 0.4 °C (98.2° ± 0.7 °F). Measurements taken on the skin (armpit, ear, forehead) gives the lowest values out of these types: 36.5 °C (97.7 °F), since these correlate relatively poorly with the core body temperature.

What is fever?

Fever is a medical sign characterized by an increased body temperature above the normal range. Fever is not considered medically significant until body temperature is above 38°C.

Fever is caused by the release of certain chemicals by the immune system, usually as a result of an infection or inflammation. Not every fever needs medical attention, but in young children, if the temperature continues to rise or if there are other worrying symptoms, a doctor should be consulted.

What causes fever?

It can be caused by a number of reasons: in most cases by infectious diseases (such as flu & pneumonia), less frequently by hormone imbalance, metabolic disorders, certain inflammatory conditions (such as rheumatoid arthritis) or even extreme sunburn or certain medications & immunizations (vaccines).

Sometimes the cause of a fever can't be identified. If you have a temperature of 38.3 C or higher for more than three weeks & your doctor isn't able to find the cause after extensive evaluation, the diagnosis may be fever of unknown origin.

Do I have to treat fever?

Fever is not by itself an illness but a defense mechanism.

However, if it rises above 39.4 °C, some actions have to be taken to reduce it. It meant that the body is no longer able to control its inner temperature.

This can either be done by using antipyretics (medications against fever), or by taking a cooling bath. The way of treatment should be defined by a doctor, based on the underlying cause, the age & condition of the patient. Infectious diseases require anti-pathogenic drugs.

By all means, extra attention should be paid to increased water-intake, to compensate for dehydration.

Young children with even low fever require special attention & immediate treatment aiming to reduce the body temperature (cooling bath or cold pack first, before turning to medications).

If an infant younger than 4 months old has rectal temperature above 38 °C , immediately call your doctor or go to an emergency room, because it could be a sign of a potentially life-threatening infection.

The same action must be taken if any child has a fever above 40 °C.

Can I wipe a pencil thermometer with alcohol?

Sterilization with chemical (including alcohol) might transform the surface of the product. Do not sterilize it with any chemical.
You can clean the pencil thermometer with a cloth containing neutral detergent.

How does the forehead thermometer MC-720 work?

This unit measures the temperature of the surface of the forehead by sensing infrared emission of the skin at the measured point & then calculates the oral-equivalent value using a unique algorithm based on actual body temperature survey data.

Why is there variance in the measurement values taken with the forehead thermometer?

#

  • Measurements were not taken at the same location.
  • The probe lens is dirty.

Why is the indicated temperature on the forehead thermometer rather high?

#

  • The unit has been stored in a cold room. When the unit has been stored in a cold room, the measured temperature may be rather high if you measure the temperature shortly after bringing the unit to a room that is at normal temperature. Measure temperature after leaving the unit for 30 minutes in the room where it will be used. It is advisable to store the unit in the room where you are going to measure temperature.
  • The probe lens has been exposed to direct sunlight.
  • Measurement was taken shortly after the subject cried.
  • Crying can increase facial temperature.

Why is the indicated temperature on the forehead thermometer rather low?

#

  • The body is sweaty. Do not use the unit when wet after swimming, bathing, or through sweating after physical exercise, as skin temperature may have fallen. Wipe away moisture & allow 30 minutes for the body to acclimatize to room temperature before measuring.
  • The probe lens is dirty. Use a swab or soft cotton moistened with 70% alcohol to clean the probe lens.
  • Measurement was taken in surface temperature mode. Use forehead measurement mode.
  • Measurement was taken shortly after the subject was outdoors in cold weather. Wait until the forehead has warmed up.
  • Measurement was taken at a location other than the forehead.

Be sure to measure exactly at the forehead, not surrounding areas such as the hairline.

How do I disinfect my ear thermometer?

The probe is the most delicate part of the ear thermometer. For the main unit, wipe off dirt on the main unit with a soft dry cloth. Never wash the unit or clean with a cleaner containing abrasive, thinner, or benzine.

For infrared sensor, when it gets dirty, wipe it lightly with a soft dry cloth or a cotton swab. Do not wipe the infrared sensor with a tissue paper or a towel.

How is Body Composition calculated?

Omron Body Composition Monitor estimates the body fat percentage by the Bioelectrical Impedance (BI) method.

Muscles or blood vessels are body tissues having a high water content that conduct electricity easily. Body fat is tissue that has low electric conductivity.

Omron Body Composition Monitor sends an extremely weak electrical current of 50 kHz and less than 500 μA through your body to determine the amount of fat tissue. This low electrical current is not felt while operating the Monitor.

The BI Method safely combines the electric resistance with the distance of the electricity conducted.

In order for the Monitor to determine body composition, it uses the electrical impedence, along with your height, weight, age and gender information to generate results based on Omron's proprietary data of body composition.

How is Body Fat Percentage classified?

It is the proportion of the weight of body fat to the body weight.

The obesity classification value advocated by Lohman (in 1986) & Nagamine (in 1972) is used as reference.

Body Fat Percentage Classification
Male Female
5.0 to 9.9% 5.0 to 19.9% -(Low)
10.0 to 19.9% 20.0 to 29.9% 0(Normal)
20.0 to 24.9% 30.0 to 34.9% +(High)
25.0% to 35.0% to ++(Very High)

How is Visceral Fat classified?

Visceral fat is body fat that is stored within the abdominal cavity and is therefore stored around a number of important internal organs such as the liver, pancreas and intestines.

Visceral fat is sometimes referred to as 'active fat' because research has shown that this type of fat plays a distinctive and potentially dangerous role affecting how our hormones function and is associated with increased risks of a number of health problems such as diabetes.

At times, the body fat percentage can be low while the visceral fat level is high.

Visceral fat level Level Classification
1 to 9 0(Normal)
10 to 14 +(High)
15 to 30 ++(Very High)

How is Skeletal Muscle Percentage classified?

Based on the proprietary data from Omron

Skeletal Muscle Percentage Classification
Male Female
5.0 to 32.8% 5.0 to 25.8% -(Low)
32.9 to 35.97 25.9 to 37.9% 0(Normal)
35.8 to 37.3% 28.0 to 29.0% +(High)
37.4 to 60.0% 29.1 to 60.0% ++(Very High)

Why is it important to know your Resting Metabolism (RM)?

60-70% of daily energy use is for basal metabolism, 20-30% is for daily activity and 10% for diet-induced thermogenisis.

Know your RM to avoid over-eating and to increase muscle mass.

What does Body Age indicates?

Body Age indication is based on one's RM and is used as a guide to one's metabolic age.

To know ones's Body Age is useful to improve one's wellbeing.

What is the ideal Body Mass Index (BMI)?

In accordance with the international index to judge obesity, an ideal body weight is at BMI "22".

Underweight = <18.5
Normal Weight = 18.5-24.9
Overweight 25-29.9
Obesity BMI of 30 or greater

Is there a recommended time to monitor body composition?

The recommended time to monitor body composition is in the morning before you exercise, eat, drink or take a shower. Measuring it at the same time everyday will give you an opportunity to develop a comparable trend and track your progress.

What is Transcutaneous Electrical Nerve Stimulation (TENS)?

TENS is a drug-free non-invasive therapy designed to reduce & relieve muscle or joint pain by applying electrical nerve stimulation to the surface of the skin near the site of the pain.

What does TENS do?

TENS can work in several ways, including: block the pain message from reaching the brain, trigger the body to produce more endorphins (=natural pain killers) or improve blood circulation.

Click here to find out more about Omron’s Pain Therapy products.

How does TENS work?

TENS relieves pain in two ways:

Standard High-Frequency Treatment

  1. Pulse Rate is set to 60 pulses per second or more.
  2. Produces a steady "buzzing" or "tingling" feeling between the electrodes
  3. Produces an electrical signal that is stronger than the pain signal that the body produces. Because the signal is perceived as stronger, it effectively blocks the pain signal from travelling along nerves to the brain.
  4. Effective for acute pain

Low-Frequency Treatment

  1. Pulse Rate is below 10 pulses per second or at "burst" mode.
  2. Produces visible muscle twitching & "tapping" or "pulsating" feeling
  3. The body reacts to this type of stimulation by releasing "endorphins" (pain-killing chemicals produced naturally in the body)
  4. These endorphins act as a chemical nerve block, effectively reducing pain by interrupting the flow of pain signals along the nerves.
  5. Effective for chronic pain, stiffness & numbness

Is TENS safe?

Yes! TENS has been prescribed by medical professionals & used for over 30 years by physicians, chiropractors, & physical therapists as an effective pain relief solution.

Click here to find out more about Omron’s Pain Therapy products.

Who can use TENS?

Adults who suffer from joint or muscle pain can use this therapy. However, it should not be used by children, pregnant women, or anyone who has an implanted metallic or electronic device. Consult your doctor if you have any questions related to your health.

How far apart should you place the Pads?
