What is a Sphygmomanometer?
A sphygmomanometer is a medical device used for measuring blood pressure. It is important to check your blood pressure because it insures the healthy functioning of your heart and the vessels in the body carrying blood; if there’s an abnormal reading on the manometer scale then that can indicate a potential dysfunction in your heart leading to a stroke, heart disease or kidney failure.
Types of Sphygmomanometers?
There are two types of sphygomomanmeters in use today
Does not require a professional clinician to measure blood pressure readings. The numbers are displayed as digits on a small monitor screen, it woks electronically, and uses the method of scillometric detection for reading blood pressure measurements, the cuff is automatically inflated as soon as the device is activated. Readings are prone to systematic errors, and comparatively inaccurate to manual measurements.
Requires a stethoscope and an expert clinician for measuring accurate readings. The structure consists of a mercury pump; a cuff that’s strapped around the arm, and a pumper for filling the cuff with pressure. Readings are more accurate when measured manually.
How to properly use a Sphygmomanometer?
Once you’ve successfully purchased a sphygmomanometer, the next step for you is to learn how to use it the correct way so you can measure your blood pressure without the need of a medical expert. Here are steps that’ll guide you on how to use your manometer.
- First of all, place your spygmomanometer on a spacious surface area where you can easily operate it, and de-tangle the pipes if needed, latch on the pipes to their positions before starting.
- As for the cuff, you need to ensure that you have the right size for your arm; when you strap it on you upper arm majority of it should be covered.
- Bring your arm up to the height of your heart such that your elbow and heart are be aligned.
- Now take the cuff and strap it onto your flexed arm one inch above the elbow pit. Insure that the cuff is fastened neither too tightly nor too loosely; it should fit your arm comfortably.
- Now position the bell of the stethoscope on the middle of the elbow-pit, and keep it firmly placed with your index finger; plug in the ear-tips for now you won’t hear anything.
- There’s a bulb (acts as a hand pump) on the instrument, and it has a valve -a screw like body- on it; tighten that valve until is stops tightening.
- Now keep applying pressure on the bulb by squeezing it keep at it till the pressure reaches 180 mm Hg; you’ll feel your upper arm being pressed by the cuff, the grip will tighten halting your blood flow. There will be silence in the stethoscope.
- Unscrew the valve to release the pressure to gradually allow the blood to flow, the pressure drops at a pace of 3 mm/sec.
- Now listen carefully on the stethoscope; the first knock you hear, note down its reading. You’ve successfully measured your systolic pressure.
- After the initial thumping the blood will smoothly start to flow and you’ll stop hearing the thumping sound. This silent flow of blood marks your diastolic pressure. Note down the reading.

Checking your blood pressure with a sphygmomanometer
How to take the reading?
You must’ve noticed that 2 different numbers appear on a manometer in such a manner 120/80 mm Hg; this is simply the reading of the blood pressure, and it indicates the units of measurements namely systolic pressure, and diastolic pressure. The upper number 120 represents the systolic pressure, while the lower number 80 indicates the diastolic pressure. Its pronounced as 120 by 180.
You’ll hear experts say that its the first sound you hear on your stethoscope when you start releasing pressure from the cuff; that’s your systolic pressure. The maximum output that is exhibited by your heart and its measured as 120mm Hg on the scale.
Diastolic pressure occurs when the blood flows smoothly, and the heart is relaxed; this occurs when the cuff pressure is further loosened and no sounds can be heard this normal flow of blood marks the diastolic pressure, and is measured 80mm Hg on the manometer.
Standard Blood Pressure Level
The standard blood pressure of a healthy adult is below 120/80 mm Hg, and above 90/60 mm Hg but the correct measurement for each individual can vary with age.
Dangerous Blood Pressure Levels
How can you know that which blood pressure level poses a threat for you, and which pressure -systolic or diastolic- is more important for determining fatal blood pressure levels?
The systolic pressure when raised to deadly levels can cause a stroke, or kidney failure. The systolic pressure is more important in determining blood pressure because its the power pump of blood in the body exhibited by the heart.
Diastolic blood pressure occurs in between beats, and according to medical experts does not possess harm, but if it drops simultaneously with an increased systolic pressure then your blood pressure is elevated e.g. 129/70 mm Hg its not high but elevated.
Here are a few readings to give a clear idea about what the numbers on the manometer scale mean:
Stage I Hypertension:
130/80 mm Hg – 139/89 mm Hg; if you get such a reading its not life threatening, however, manage your blood pressure with the help of your doctor, if this pressure was a one time reading and it subsides then you don’t have high blood pressure; if it persists even after medication for a prolonged time-period then tell your doctor.
Stage II Hypertension:
140/90 mm Hg or more; obtaining this reading indicates an alarming problem your doctor will most certainly prescribe you with medications, and you’ll need to change up on your lifestyle habits to stay healthy.
Lethal Blood pressure level:
180/120 mm Hg and above; if your blood pressure is this high then you need to rush to the hospital immediately, because it poses immediate risk to your life.
