12. Measurement of Blood
pressure
•
•
•
•
•
•
•
•
•
Measuring blood pressure is a routine procedure in healthcare that
provides important information about cardiovascular health. Blood
pressure is typically expressed as two values: systolic pressure over
diastolic pressure. The unit of measurement is millimeters of
mercury (mmHg).
Steps for Measuring Blood Pressure:
Preparation:
Have the person sit in a comfortable chair with their back supported
and feet flat on the floor.
Rest for at least 5 minutes before the measurement.
Ensure a calm environment, as stress can temporarily elevate blood
pressure.
Equipment:
Use a blood pressure cuff (sphygmomanometer) and a stethoscope.
Alternatively, automated blood pressure monitors are available for
home use.

13. •
•
•
•
•
•
•
Positioning the Cuff:
Place the cuff around the upper arm, about an
inch above the elbow.
The bottom edge of the cuff should be about
an inch above the crease of the elbow.
Locating the Brachial Artery:
Use the stethoscope to locate the brachial
artery on the inside of the elbow.
Inflation:
Inflate the cuff by squeezing the bulb or
activating the automated monitor. This
temporarily cuts off blood flow.

14. •
•
•
•
•
•
•
•
Release the Air:
Gradually release the air from the cuff. This allows blood
to flow back into the artery.
Listening for Sounds:
As the cuff deflates, listen for the first sound (Korotkoff
sounds). This is the systolic pressure, the force of blood
against the artery walls when the heart is contracting.
Complete Release:
Continue listening until the sounds disappear. This is
the diastolic pressure, the pressure when the heart is at
rest between beats.
Recording the Measurement:
Record the systolic pressure over the diastolic pressure.
For example, 120/80 mmHg.

15. •
•
•
•
•
•
•
•
•
•
Tips for Accurate Measurements:
Consistency:
Measure at the same time each day for consistency.
Use the same arm for all measurements.
Empty Bladder:
Ensure the person has emptied their bladder before the
measurement.
Avoid Stimulants:
Avoid caffeine, tobacco, and exercise for at least 30
minutes before measuring.
Comfortable Clothing:
Wear a short-sleeved shirt or roll up sleeves to expose
the upper arm.

16. •
•
•
•
•
Quiet Environment:
Choose a quiet environment to minimize external
distractions.
Arm Position:
Keep the arm supported at heart level during
measurement.
If monitoring blood pressure at home, follow the
guidelines provided by healthcare professionals, and
report any concerning readings to your healthcare
provider. Elevated or consistently high blood pressure
readings may require further assessment and
management to reduce the risk of cardiovascular
problems. Always consult with healthcare
professionals for personalized advice and guidance on
blood pressure management.

20. Measurement of blood
glucose
•
•
•
•
•
•
Measuring capillary blood glucose levels is a
common method used to monitor and manage
diabetes. This process involves using a glucometer
to obtain a small blood sample, typically from the
fingertip, for immediate analysis. Here are the
general steps for measuring capillary blood glucose:
Steps for Measuring Capillary Blood Glucose:
Preparation:
Wash your hands thoroughly with soap and warm
water. Dry them completely.
Gather Supplies:
Ensure you have all necessary supplies: a glucometer,
test strips, a lancing device, and alcohol swabs if
needed.

21. •

•
Prepare the Lancing Device:
Load a lancet into the lancing device according to the
device's instructions. Adjust the depth setting based
on your skin type and the device's recommendations.
Prep the Test Strip:
Insert a test strip into the glucometer, following the
device's instructions.
Clean the Finger:
If using an alcohol swab, clean the fingertip you plan to
use. Let it dry completely.
Prick the Finger:
Use the lancing device to prick the side of your
fingertip. This helps minimize pain while still obtaining
an adequate blood sample.

22. •
•
•
•
•
•
•
•
Collect the Blood:
Gently squeeze the fingertip to obtain a small drop of
blood. Hold the glucometer to the blood drop, allowing
it to be drawn into the test strip.
Wait for Results:
The glucometer will analyze the blood sample and
display the blood glucose level on the screen.
Record the Result:
Record the result in a logbook or on a digital device.
Note the time of day and any relevant circumstances,
such as recent meals or physical activity.
Dispose of Materials:
Safely dispose of the lancet and test strip in an
appropriate container.

23. •
•
•
•
•
•
•
•
•
Tips for Accurate Measurements:
Regular Monitoring:
Follow the monitoring schedule recommended by
your healthcare provider.
Proper Storage:
Store the test strips and the glucometer according to
the manufacturer's instructions.
Calibration:
Ensure the glucometer is properly calibrated,
following the manufacturer's recommendations.
Control Solution:
Occasionally use a control solution to check the

pain and reduce the risk of infection.
Temperature Considerations:
Be aware of temperature conditions, as extreme
temperatures can affect the accuracy of the
glucometer.
Always consult with your healthcare provider about
the frequency of blood glucose monitoring and the
target ranges suitable for your specific health
condition. Regular monitoring is essential for
effective diabetes management, helping
individuals make informed decisions about diet,
medication, and lifestyle choices.

30. Calculation of body mass
index
•
•
•
•
Body Mass Index (BMI) is a measure of body
fat based on a person's weight in relation to
their height. The BMI calculation is a simple
formula that provides a general indication of
whether a person has a healthy body weight for
their height. Here's how you calculate BMI:
BMI Formula:
The formula for BMI is as follows:
BMI=Weight (kg)Height (m)2BMI=Height (m)2
Weight (kg)

31. •
•
•
•
•
•
•
Weight (kg):
Measure your weight in kilograms.
Height (m):
Measure your height in meters.
Calculation:
Square the height in meters (Height
(m)2Height (m)2).
Divide the weight in kilograms by the squared
height.

32. •
•
•
•
•
•
•
•
•
•
•
Example:
Let's say someone weighs 70 kilograms and has a
height of 1.75 meters.
BMI=701.752BMI=1.75270
BMI=703.0625BMI=3.062570
BMI≈22.85BMI≈22.85
BMI Categories:
BMI is generally categorized into different ranges:
Underweight: BMI less than 18.5
Normal weight: BMI 18.5 to 24.9
Overweight: BMI 25 to 29.9
Obese: BMI 30 or greater

33. •
•
It's important to note that while BMI is a useful
screening tool for identifying potential weight-
related health issues, it does not directly
measure body fat percentage or distribution.
Therefore, individuals with high muscle mass
may have a higher BMI without having excess
body fat.
Always consult with healthcare professionals
for a comprehensive assessment of your health.
They can provide personalized advice based on
various factors, including BMI, but also taking
into account your overall health, lifestyle, and
any existing medical conditions.

34. Categorization based on BMI
•
•
•
•
•
•
•
•
•
Body Mass Index (BMI) is commonly categorized
into different ranges to provide a general indication of
an individual's body weight in relation to their height.
Here are the commonly used BMI categories:
Underweight:
BMI less than 18.5
Normal Weight:
BMI between 18.5 and 24.9
Overweight:
BMI between 25 and 29.9
Obese:
BMI of 30 or greater

35. •
•
•
•
•
•
•
BMI Categorization Guidelines:
Underweight:
Individuals with a BMI below 18.5 may be considered
underweight. This can be associated with health risks,
including nutrient deficiencies and a weakened immune
system.
Normal Weight:
A BMI between 18.5 and 24.9 is generally considered a
healthy weight range for most adults. It is associated
with a lower risk of weight-related health issues.
Overweight:
Individuals with a BMI between 25 and 29.9 are
classified as overweight. Overweight individuals may be
at an increased risk of developing conditions such as
heart disease, type 2 diabetes, and certain cancers.

36. •
•
•
•
•
•
Obese:
Obesity is further categorized into three classes
based on BMI:
Class 1 (Moderate Obesity): BMI between 30 and
34.9
Class 2 (Severe Obesity): BMI between 35 and 39.9
Class 3 (Very Severe or Morbid Obesity): BMI of 40
or greater
Obesity is associated with an elevated risk of
serious health conditions, including cardiovascular
diseases, type 2 diabetes, sleep apnea, and joint
problems.

37. •
•
•
•
•
•
•
Considerations:
Limitations of BMI:
While BMI is a widely used tool, it has limitations, particularly
in assessing individuals with high muscle mass. Athletes, for
example, may have a higher BMI due to muscle weight rather
than excess body fat.
Individual Differences:
BMI does not account for individual variations in body
composition or fat distribution. Some individuals with
a "normal" BMI may still have excess body fat, particularly if it
is concentrated around the abdomen.
Comprehensive Health Assessment:
BMI is just one part of a comprehensive health assessment.
Other factors, such as waist circumference, body fat
percentage, and overall health status, should also be
considered.

38. • It's important to note that BMI is a screening
tool and not a diagnostic measure. For a more
accurate assessment of health and weight-
related risks, individuals should consult with
healthcare professionals who can consider
multiple factors in the context of an individual's
overall health and lifestyle.

39. Measurement of peak
expiratory flow rate (PEFR)
•
•
•
•
•
•
•
•
Peak Expiratory Flow Rate (PEFR) is a measure of how fast a
person can exhale air during a forceful breath. It's often used
to monitor and manage respiratory conditions such as
asthma. PEFR is measured in liters per minute (L/min). Here
are the general steps for measuring Peak Expiratory Flow
Rate:
Steps for Measuring PEFR:
Preparation:
Stand or sit up straight.
Reset the Peak Flow Meter:
Ensure that the peak flow meter is at the lowest level. This is
usually done by moving the indicator or marker to the bottom
of the scale.
Hold the Peak Flow Meter:
Hold the peak flow meter with both hands, making sure that
fingers do not block the mouthpiece.

40. •
•
•
•
•
•
•
•
Take a Deep Breath:
Inhale as deeply as possible, filling the lungs
completely.
Place Lips Around Mouthpiece:
Place the lips tightly around the mouthpiece, forming
a good seal.
Blow Out as Hard and Fast as Possible:
Blow out as hard and fast as possible in a single
breath, aiming the exhaled air into the mouthpiece.
Record the Reading:
Record the number indicated by the marker on the
scale where it stops. This is your Peak Expiratory
Flow Rate.

41. •
•
•
•
•
•
•
Repeat:
Repeat the process two more times to ensure
consistency. Take note of the highest of the
three measurements.
Tips for Accurate Measurements:
Consistency:
Perform the test at the same time each day for
consistent readings.
Correct Technique:
Ensure the lips form a tight seal around the
mouthpiece to prevent air leakage.

42. •
•
•
•
•
•
•
•
•
•
Full Inhalation:
Inhale as deeply as possible before performing the test.
Smooth Exhalation:
Blow out in a smooth, continuous motion rather than in short
bursts.
No Blocking:
Ensure that fingers do not block the end of the peak flow
meter.
Avoid Eating or Drinking:
Avoid eating or drinking right before the test to prevent any
interference.
Record Results:
Keep a record of the measurements to track changes over
time.

43. •
•
•
•
•
•
•
•
•
Interpreting Results:
Personal Best:
Your personal best PEFR is the highest reading you achieve
when your asthma is well-controlled.
Green Zone:
If your reading is in the green zone, it indicates good lung
function and that your asthma is under control.
Yellow Zone:
A reading in the yellow zone suggests caution, indicating a
decline in lung function. Follow your asthma action plan for
adjustments in medication.
Red Zone:
If your reading is in the red zone, it signals a medical
emergency, and you should seek immediate medical
attention.

44. • Monitoring PEFR is an important part of
asthma management. Regular measurements
help individuals and healthcare providers
assess lung function, adjust treatment plans,
and respond promptly to changes in respiratory
health. Always follow your healthcare provider's
guidance on using and interpreting PEFR
measurements.
