This document provides instructions on measuring and interpreting vital signs including temperature, respiration, pulse, and blood pressure. Key steps are outlined for properly measuring each vital sign, such as counting respirations for 15 seconds and multiplying by 4. Normal ranges are given for each sign with notes on abnormal readings. Blood pressure classification ranges from normal to hypertensive are also provided.
Age Pulse rate
(beats per minute)
Newborn (resting) 100–180
Infant (resting) 80–150
Child 26 years 75–120
Child 6–12 years 70–110
Adolescent–adult 60–90
Ask whether the patient has walked,
climbed stairs, or otherwise exerted
themself in the last 20 minutes. If not,
you can proceed. If the answer is yes,
wait 20 minutes before taking the reading.
This will help to prevent false readings.
2 Make sure the patient is relaxed and
comfortable.
3 Place the tips of your first and second
finger on the inside of the patient’s wrist
(Figure 1).
4 Press gently against the pulse. Take
your time to note any irregularities in
strength or rhythm.
5 If the pulse is regular and strong,
measure the pulse for 30 seconds.
Double the number to give the beats
per minute (e.g.: 32 beats in 30
seconds means the pulse is 64 beats
per minute). If you noticed changes in
rhythm or strength, you must measure
the pulse for a full minute.
6 Record the pulse rate (the number of
beats per minute) in the patient’s notes
and describe its strength and rhythm.
Compare the pulse rate with the values
in the Table 1 and record whether the
pulse is normal, slow or fast. Any abnormalities should be recorded and
reported to the senior nurse and doctor.
7 Strength of the pulse is a very
subjective measurement, but an experienced nurse will compare it with what
has been felt previously in other
patients. Describe the puse as ‘weak’,
‘faint’, ‘strong’ or ‘bounding’.
8 Think about the rhythm of the pulse. Is
it regular? If irregular, in what way?
Cardiac problems may present as a
regular missed beat, for

Pulse and Blood pressure measurement for the first-year students
Clinical Module
By Usama Ragab
“Blood pressure is the single most important test that we do, if left untreated it causes strokes, heart attacks, and peripheral vascular disease”.
Vital signs
The four main vital signs routinely monitored by medical professionals and health care providers include the following:
Body temperature.
Pulse rate.
Respiration rate (rate of breathing)
Blood pressure
Vital signs provide important information about patients’ clinical condition and inform any required interventions
Inadequate response to deterioration is the most common cause of reported critical incidents
Nurses’ compliance with observation protocols can be poor, particularly at night
Peaks in observation frequency suggests the timing of observation is often driven by ward routines
Electronic vital signs devices and early warning score charts may increase vital signs measurements, but further research is needed

A Guide to the Physical Examination - By Dr. Sam GharbiSam Gharbi
Dr Sam Gharbi had always envisioned a better model for learning than the traditional textbook, particularly in the 21st Century. This
guide is meant to combine the written word with pictures, videos, as well as dynamic e-tools for note taking, highlighting, study cards and other memory aides in an effort to create an integrated environment that evolves with the learner from day 1 of medical school until completion of training, and hopefully beyond.
Temperature, pulse, respiration, blood pressure (BP), and oxygen saturation, are measurements that indicate a person’s hemodynamic status. These are the five vital signs most frequently obtained by health care practitioners (Perry, Potter, & Ostendorf, 2014). Vital signs will potentially reveal sudden changes in a patient’s condition and will also measure changes that occur progressively over time. A difference between patients’ normal baseline vital signs and their present vital signs may indicate the need for intervention (Perry et al., 2014). Checklist 15 outlines the steps to take when checking vital signs.
this is a detailed study on blood pressure measurement on clinical watching , methods , equipment's , common problems ,and all major aspects of blood pressure measurement is mentioned in detail .

The force of circulating blood on the walls of the arteries. Blood pressure is taken using two measurements: systolic (measured when the heart beats, when blood pressure is at its highest) and diastolic (measured between heart beats, when blood pressure is at its lowest).A blood pressure measurement is a test that measures the force (pressure) in your arteries as your heart pumps. Blood pressure is measured as two numbers: Systolic blood pressure (the first and higher number) measures pressure inside your arteries when the heart beats.

General Considerations
The patient should not have had alcohol, tobacco, caffeine, or
performed vigorous exercise within 30 minutes of the exam.
Ideally the patient should be sitting with feet on the floor and their
back supported. The examination room should be quiet and the patient
comfortable.
Vital Signs
Page 1
2. History of hypertension, slow or rapid pulse, and current medications
should always be obtained.
Temperature
Temperature can be measured is several different ways:
Oral with a glass, paper, or electronic thermometer (normal
98.6F/37C)
Axillary with a glass or electronic thermometer (normal 97.6F/36.3C)
Rectal or "core" with a glass or electronic thermometer (normal
99.6F/37.7C)
Aural (the ear) with an electronic thermometer (normal 99.6F/37.7C)
Of these, axillary is the least and rectal is the most accurate.
Respiration
1. Best done immediately after taking the patient's pulse. Do not
announce that you are measuring respirations.
2. Without letting go of the patients wrist begin to observe the patient's
breathing. Is it normal or labored?
3. Count breaths for 15 seconds and multiply this number by 4 to yield
the breaths per minute.
4. In adults, normal resting respiratory rate is between 14-20
breaths/minute. Rapid respiration is called tachypnea.
Pulse
1. Sit or stand facing your patient.
2. Grasp the patient's wrist with your free (non-watch bearing) hand
(patient's right with your right or patient's left with your left). There is
no reason for the patient's arm to be in an awkward position, just
imagine you're shaking hands.
3. Compress the radial artery with your index and middle fingers.
4. Note whether the pulse is regular or irregular:
Regular - evenly spaced beats, may vary slightly with respiration
Regularly Irregular - regular pattern overall with "skipped" beats
Irregularly Irregular - chaotic, no real pattern, very difficult to
measure rate accurately
Vital Signs

3. 5. Count the pulse for 15 seconds and multiply by 4.
6. Count for a full minute if the pulse is irregular.
7. Record the rate and rhythm.
Interpretation
A normal adult heart rate is between 60 and 100 beats per minute
(see below for children).
A pulse greater than 100 beats/minute is defined to be tachycardia.
Pulse less than 60 beats/minute is defined to be bradycardia.
Tachycardia and bradycardia are not necessarily abnormal. Athletes
tend to be bradycardic at rest (superior conditioning). Tachycardia is a
normal response to stress or exercise.
Blood Pressure
1. Position the patient's arm so the anticubital fold is level with the heart.
Support the patient's arm with your arm or a bedside table.
2. Center the bladder of the cuff over the brachial artery approximately 2
cm above the anticubital fold. Proper cuff size is essential to obtain
an accurate reading. Be sure the index line falls between the size
marks when you apply the cuff. Position the patient's arm so it is
slightly flexed at the elbow. [4]
3. Palpate the radial pulse and inflate the cuff until the pulse disappears.
This is a rough estimate of the systolic pressure. [5]
4. Place the stetescope over the brachial artery. [6]
5. Inflate the cuff to 30 mmHg above the estimated systolic pressure.
6. Release the pressure slowly, no greater than 5 mmHg per second.
7. The level at which you consistantly hear beats is the systolic pressure.
[7]
8. Continue to lower the pressure until the sounds muffle and disappear.
This is the diastolic pressure. [8]
9. Record the blood pressure as systolic over diastolic ("120/70" for
example).
Vital Signs
Page 3
4. Interpretation
Higher blood pressures are normal during exertion or other stress.
Systolic blood pressures below 80 may be a sign of serious illness or
shock.
Blood pressure should be taken in both arms on the first encounter. If
there is more than 10 mmHg difference between the two arms, use
the arm with the higher reading for subsequent measurements.
It is frequently helpful to retake the blood pressure near the end of the
visit. Earlier pressures may be higher due to the "white coat" effect.
Always recheck "unexpected" blood pressures yourself.
Blood Pressure Classification in Adults
Category Systolic Diastolic
Normal <140 <90
Isolated Systolic Hypertension >140 <90
Mild Hypertension 140-159 90-99
Moderate Hypertension 160-179 100-109
Severe Hypertension 180-209 110-119
Crisis Hypertension >210 >120
In children, pulse and blood pressure vary with the age. The following
table should serve as a rough guide:
Average Pulse and Blood Pressure in Normal Children
Age Birth 6mo 1yr 2yr 6yr 8yr 10yr
Pulse 140 130 115 110 103 100 95
Systolic BP 70 90 90 92 95 100 105

5. Notes
1. For definitive study refer to Bates' Pocket Guide to Physical
Examination and History Taking by Lynn S. Bickley
2. Unlike pulse, respirations are very much under voluntary control. If
you tell the patient you are counting their breaths, they may change
their breathing pattern. You cannot tell someone to "breath normally,"
normal breathing is involuntary.
3. With an irregular pulse, the beats counted in any 15 second period
may not represent the overall rate. The longer you measure, the more
these variations are averaged out.
4. Do not rely on pressures obtained using a cuff that is too small or too
large. This is frequently a problem with obese or muscular adults
where the regular cuff is too small. The pressure recorded will most
often be 10, 20, even 50 mmHg too high! Finding a large cuff may be
inconvenient, but you will also "cure" a lot of high blood pressure.
5. Maximum Cuff Pressure - When the baseline blood pressure is already
known or hypertension is not suspected, it is acceptable in adults to
inflate the cuff to 200 mmHg and go directly to auscultating the blood
pressure. Be aware that there could be an auscultory gap (a silent
interval between the true systolic and diastolic pressures).
6. Bell or Diaphragm? - Even though the Korotkoff sounds are low
frequency and should be heard better with the bell, it is often difficult
to apply the bell properly in the anticubital fold. For this reason, it is
common practice to use the diaphragm when taking blood pressure.
7. Systolic Pressure - In situations where ausculation is not possible, you
can determine systolic blood pressure by palpation alone. Deflate the
cuff until you feel the radial or brachial pulse return. The pressure by
auscultation would be approximately 10 mmHg higher. Record the
pressure indicating it was taken by palpation (60/palp).
8. Diastolic Pressure - If there is more than 10 mmHg difference between
the muffling and the disappearance of the sounds, record all three
numbers (120/80/45).
