(sehat/sakit)
Pengukuran TTV
Sesuai permintaan, untuk melengkapi data
dasar pengkajian
 Sesuai permintaan dokter
 Sekali sehari  klien stabil
 Setiap 4 jam  1 /> TTV abnormal
 Setiap 5 – 15mnt  klien tidak stabil atau
resiko perubahan fisiologi secara cepat post
op
 Ketika kondisi klien tampakberubah

Setiap menit atau lebih sering, bila ada
perubahan signifikan dari hasil
pengukuran sebelumnya
 Ketika klien merasa tidak seperti biasa
 Sebelum,selama dan setelah transfusi
 Sebelum pemberian obat  efek

SUHU TUBUH
SUHU TUBUH MENUNJUKKAN
KEHANGATANTUBUH MANUSIA
 Panas tubuh
Diproduksi :

Hilang : melalui kulit,
paru, dan produk
sisa melalui proses
radiasi,
konduksi,konveksi,
evaporasi
exercise dan
metabolisme
makanan
Suhu tubuh mencerminkan keseimbangan
antara produksi panas dan kehilangan
panas, dan diukur dalam unit panas yang
disebut derajat.
 Ada 2 macam suhu tubuh:

Suhu inti  jaringan dalam tubuh: rongga
abdomen dan rongga pelvic  Relatif konstan
2. Suhu permukaan  suhu kulit, SC, dan lemak
SC  naik dan turun merespon thd
lingkungan
1.
FAKTOR-FAKTOR YANG
MEMPENGARUHI PRODUKSI PANAS
1. BMR : jumlah energi yang digunakan
ubuh untuk melakukan aktivitas utama
seperti bernafas
2. AKTIVITAS OTOT: termasuk menggigil,
meingkatkan metabolisme rate
3. TYROXINE OUTPUT: meningkatnya
output tyroxine akan meningkatkan
metabolisme sel seluruh tubuh
4. Stimulasi/respon Epineprin,
norephinephrine, simpatis. Hormon ini
dengan seketika meningkatkan
metbolisme sel dibeberapa jaringan
tubuh
5. Fever, meningkatkan jumlah
metabolisme tubuh
MEKANISME KEHILANGAN
PANAS
Radiasi adalah pemindahan panas dari
permukaan objek tertentu ke permukaan
onjek yang lain tanpa adanya kontak antara
kedua objek, yang paling sering adalah
dengan sinar inframerah. (atau penyebaran
panas dengan gelombang elektromagnetik)
Konduksi adalah perpindahan panas ke objek
lain melalui kontak langsung
Evaporasi (penguapan) adalah perubahan
dari cairan menjadi uap. Seperti cairan tubuh
dalam bentuk keringat menguap dari kulit
Konveksi adalah penyebaran panas oleh
karena pergerakan udara dengan kepadatan
yang tidak sama. orang yang
menggunakan kipas angin
Mekanisme perpindahan panas
FAKTOR YANG MEMPENGARUHI
SUHU TUBUH
Circadian Rhythms perubahan fisiologis, seperti
perubahan suhu dan TTV yang lain secara
fluktuatif : pagi hari lebih rendah dibandingkan
sore hari, suhu tubuh berfluktuasi 0,28o – 1,1oC
selama periode 24jam
Usia  suhu tuuh bayi dan anak-anak berubah
lebih cepat dalam merespon perubahan
panas dan dingin
Hormonal  perempuan cenderung
lebih fluktuatif dibandingkan dengan
laki-laki, karena perubahan hormon
Stress  respon tubuh terhadap stress
fisik dan emosi akan meningkatkan
produksi epineprin dan nor epineprin
sehingga mengakibatkan
peningkatan metabolisme rate
peningkatan suhu tubuh
SUHU TUBUH NORMAL
Suhu Permukaan : 36,8o – 37,4o C (96,6o – 99,3o
F)
 Suhu inti
: 36,4o – 38o C (97,5o – 100,4o F)

Suhu diukur dengan termometer.
Termometer yang paling dikenal Celsius
(C), Reaumur (rankine) (R),
Fahrenheit (F), Kelvin (K), dengan
perbandingan antara satu dan
lainnya mengikuti:
C:R:(F-32) = 5:4:9
PENGATURAN SUHU
Suhu manusia dikendalikan
oleh HIPOTHALAMUS
Anterior 
hilangnya panas
Vasodilatasi dan
bengkak
Posterior  produksi dan
menyimpan panas
1. Menyesuaikan dengan
sirkulasi darah
2. Piloerectile (mengatur
konstriksi atau dilatasi
pori-pori kulit)
3. Respon menggigil
Hipotalamus meningatkan produksi panas
dengan cara meningkatkan metabolisme
melalui sekresi hormon thyroid, yaitu
epinephrin dan norepinephrin medulla
adrenalis
Dalam keadaan normal, hipotalamus menjaga
suhu inti “set point”(suhu tubuh optimal)
sebesar 1˚C oleh perubahan suhu
permukaan tubuh dan darah
Suhu > 41°C, dan < 34°C
indikasi kerusakan di
pusat pengaturan
hipotalamus

PEMERIKSAAN NADI
 Nadi adalah sensasi
denyutan seperti gelombang
yang dapat dirasakan/
dipalpasi di arteri perifer,
terjadi karena gerakan atau
aliran darah ketika
konstraksi jantung





Nadi adalah gelombang darah yang
dibuat oleh kontraksi ventrikel kiri
jantung
Pada orang dewasa kontraksi jantung
60 – 100 x/mnt saat istirahat
Cardiac output; adalah volume darah
yang dipompakan kedalam arteri oleh
jantung dan = SVxHR
Nadi Perifer; nadi yang berada jauh
dari jantung, ex: kaki, radialis, leher
Nadi apical; nadi central, lokasinya di
apex jantung
KECEPATAN NADI (PULSE RATE)
Pulse Rate (jumlah denyutan perifer
yang dirasakan selama 1 menit) 
dihitung dengan menekan arteri perifer
dengan menggunakan ujung jari
 Tachycardia: nadi >100 -150 x/mnt
jantung overwork  oksigenasi sel tidak
adequat
 Palpitasi : perasaan berdebar-debar,
sering menyertai tachycardi

Denyut Nadi sangat fluktuatif dan
meningkat dengan :
1. exercise,
2. illness,
3. injury, and
4. emotions.
 wanita cenderung dibandingkan
laki-laki.
 Athlets, mis. Pelari, bisa jadi heart
rates-nya 40 x/mnt dan tidak
masalah.

Bradycardia : denyut nadi < 60 x/mnt
kejadian lebih sedikit dibandingkan
tachycardia
FACTOR YANG MEMPENGARUHI NADI
1.
2.
3.
Usia; peningkatan usia, nadi berangsurangsur menurun
Jenis Kelamin; pria sedikit lebih
rendah daripada wanita (P=60-65 x/mnt
ketika istirahat, W=7-8 x/mnt lebih
cepat)
Circadian rhythm; rata-rata menurun
pada pagi hari dan meningkat pada
siamg dan sore hari
4. Bentuk tubuh; tinggi, langsing biasanya denyut
jantung lebih pelan dan nadi lebih sedikit
dibandingkan orang gemuk
5. Aktivitas dan exercise; nadi akan meningkat
dengan aktivitas dan exercise dan menurun
dengan istirahat
6. Stress dan emosi; rangsangan syaraf simpatis
dan emosi seperti cemas, takut, gembira
meningkatkan denyut jantung dan nadi.
Nyeri, adalah stressor yang dapat memacu
nadi lebih cepat
7. Suhu Tubuh; setiap peningkatan 1°F  nadi
meningkat 10x/mnt, peningkatan 1°C  nadi
meningkat 15x/mnt. Sebaliknya bila terjadi
penurunan suhu tubuh maka nadi akan menurun
8. Volume darah; kehilanngan darah yang berlebihan
akan menyebabkan peningkatan nadi
9. obat-obatan; beberapa obat dapat menurunkan
atau meningkatkan kontraksi jantung. Golongan

ekshalasi

Mechanics and regulation of breathing
During inhalation, the diaphragm contracts the ribs
move upward and outward, and the sternum
moves outward, thus enlarging the thorax and
permitting the lungs to expand.
During exhalation. The diaphragm relaxes, the
ribs move downward and inward, and the
sternum moves inward, thus decreasing the size
of the thorax as the lungs are compressed.
Respiration is controlled by (a) respiratory
centers in the medulla oblongata and the pons
of the brain and (b) by chemo receptors
located centrally in the medulla and
peripherally in the carotid and aortic bodies.
External respiration; the interchange of oxygen
and carbon dioxide between the alveoli of the
lungs and the pulmonary blood. Internal
respiration; the interchange of these same
gases between the circulating blood and the
cells of the body tissues.
The respiratory rate is normally described in
breaths per minute, normal in depth and rate
called eupnea. Bradypnea; abnormally slow
respirations. Tachypnea; abnormally fast
respirations. Apnea; the absence of
breathing.
Abnormal Respiratory Rate

Respiration rates
over 25 or under 12
breaths per minute
(when at rest) may
be considered
abnormal
under 12 breaths
over 25 breaths
Respiratory Rate

Normal respiration
rates at rest range
from 15 to 20
breaths per minute.
In the cardiopulmonary illness, it
can be a very
reliable marker of
disease activity.

Factors affecting Respirations
Factors increase the rate:
○ Exercise
○ Increase metabolism
○ Stress
○ Increased environmental temperature
○ Lowered oxygen concentration
Factors decrease respiration rate:
Decreased environmental temperature
 Certain medications such as narcotics
 Increased intra cranial pressure

Respiration depth; is generally described as
normal, deep, or shallow. Deep respirations;
large volume of air is inhaled and exhaled,
inflated most of the lungs.
Shallow breathing involve the exchange of a
small volume of air and often the minimal use
of a lung tissue
Hyperventilation; refers to very deep, rapid
respiration.
Hypoventilation; refers to very shallow
respirations
Respiratory rhythm refers to the regularity of the
expirations and the inspirations .An respiratory
rhythm can be described as regular or irregular.
- Cheyne-stokes breathing, from very deep to very
shallow breathing and temporary apnea.
Breath sounds
- Stridor, harsh sound heard during inspiration with
laryngeal obstruction
- Stertor, snoring respiration usually due to a
partial obstruction of the upper airway.
- Wheeze, continuous, high pitched musical sound
occurring on expiration when air moves through
narrowed or partially obstructed air way.
Secretions and coughing
- Hemoptysis, the presence of blood in the sputum
- Productive cough, a cough accompanied by
expectorated secretions
- Nonproductive cough, a dry, harsh cough without
secretions
Preparation for measurement

Patient should
abstain from eating,
drinking, smoking
and taking drugs that
affect the blood
pressure one hour
before
measurement.
Remember the following for accuracy of
your readings

Instruct your patients
to avoid coffee,
smoking or any other
unprescribed drug
with
sympathomimetic
activity on the day of
the measurement
Preparation for measurement

Because a full
bladder affects the
blood pressure it
should have been
emptied.
Preparation for measurement
Painful procedures
and exercise should
not have occurred
within one hour.
 Patient should have
been sitting quietly
for about 5 minutes.

Preparation for measurement

BP take in quiet room

of day.
Position of the Patient
Sitting position
 Arm and back are
supported.
 Feet should be
resting firmly on the
floor
 Feet not dangling.

Position of the arm
The measurements should be made on the right arm
whenever possible.
 Patient arm should be resting on the desk and raised
(by using a pillow)

Position of the arm

Raise patient arm so that the brachial artery is roughly
at the same height as the heart. If the arm is held too
high, the reading will be artifactually lowered, and vice
versa.
Position of the arm
Palm is facing up.
 The arm should remain somewhat bent and
completely relaxed

In order to measure the Blood
Pressure (equipment)

Pediatric Cuff size
 Minimum Cuff Width:
2/3 length of upper
arm
 Minimum Cuff length:
Bladder nearly
encircles arm
In order to measure the Blood
Pressure (equipment)

Adult Cuff size
 Cuff Width: 40% of
limb's circumference
 Cuff Length: Bladder at
80% of limb's
circumference
In order to measure the Blood
Pressure (equipment)

Adult Cuff size
 Indications for large
cuff or thigh cuff
○ Upper arm
circumference >34 cm
 Indications for forearm
cuff (with radial
palpation)
○ Upper arm
circumference >50 cm
Blood Pressure

If it is too small, the
readings will be
artificially elevated.
The opposite occurs
if the cuff is too large.
Clinics should have
at least 2 cuff sizes
available, normal and
large.
In order to measure the Blood
Pressure (Cuff Position)


Patient's arm
slightly flexed at
elbow
Push the sleeve up,
wrap the cuff around
the bare arm
In order to measure the Blood
Pressure (Cuff Position)



Cuff applied directly
over skin (Clothes
artificially raises
blood pressure )
Position lower cuff
border 2.5 cm
above antecubital
Center inflatable
bladder over
brachial artery
Measurement of the pulse rate

The manometer
scale should be at
eye level, and the
column vertical. The
patient should not be
able to see the
column of the
manometer
In order to measure the BP
 Feel
for a pulse
from the artery
coursing through
the inside of the
elbow
(antecubital
fossa).
In order to measure the BP
Wrap the cuff around
the patient's upper
arm
 Close the thumbscrew.

In order to measure the BP

With your left hand
place the
stethoscope head
directly over the
artery you found.
Press in firmly but not
so hard that you
block the artery.
Technique of BP measurement

Use your right hand
to pump the squeeze
bulb several times
and Inflate the cuff
until you can no
longer feel the pulse
to level above
suspected SBP
Technique of BP measurement

If you immediately
hear sound, pump up
an additional 20
mmHg and repeat
Technique of BP measurement

Deflate cuff slowly at
a rate of 2-3 mmHg
per second until you
can again detect a
radial pulse
Technique of BP measurement

Listen for auditory
vibrations from artery
"bump, bump, bump"
(Korotkoff)
In order to measure the BP

Systolic blood
pressure is the
pressure at which
you can first hear the
pulse.
In order to measure the BP

Diastolic blood pressure is the last pressure at
which you can still hear the pulse
In order to measure the BP

Avoid moving your
hands or the head of
the stethescope while
you are taking
readings as this may
produce noise that
can obscure the
Sounds of Koratkoff.
Technique of BP measurement
 BP
must take
in both arms
and one lower
extremity.
In order to measure the BP

The two arm
readings should be
within 10-15 mm Hg.
Differences greater
then 10-15 imply
differential blood flow.
In order to measure the BP

If you wish to repeat
the BP measurement
you should allow the
cuff to completely
deflate, permit any
venous congestion in
the arm to resolve
and then repeat a
minute or so later.
Remember the following for accuracy
of your readings

If the BP is
surprisingly high or
low, repeat the
measurement
towards the end of
your exam
(Repeated blood
pressure
measurement can
be uncomfortable).
In order to measure the BP

You can verify the
SBP by palpation.
Place the index and
middle fingers of
your right hand over
the radial artery.
In order to measure the BP

Diastolic blood
pressure allow free
flow of blood without
turbulence and thus
no audible sound.
These are known as
the Sounds of
Koratkoff.
Blood pressure

The minimal SBP
required to maintain
perfusion varies with
the individual.
Interpretation of low
values must take into
account the clinical
situation.
Blood pressure for adult

Physician will want to
see multiple blood
pressure
measurements over
several days or
weeks before making
a diagnosis of
hypertension and
initiating treatment.


Remember the following for accuracy
of your readings

Orthostatic (postural)
measurements of
pulse and blood
pressure are part of
the assessment for
hypovolemia.
Remember the following for accuracy
of your readings

First measuring BP
when the patient is
supine and then
repeating them after
they have stood for
2 minutes, which
allows for
equilibration.
Remember the following for accuracy
of your readings
 Systolic
blood
pressure does
not vary by more
then 20 points
when a patient
moves from
lying to standing.
Remember the following for accuracy
of your readings

Orthostatic
measurements may
also be used to
determine if postural
dizziness (diabethic
autonomic nervous
system dysfunction)
is the result of a fall
in blood pressure.
Vital signs
Oxygen Saturation

Over the past
decade, Oxygen
Saturation
measurement of gas
exchange and red
blood cell oxygen
carrying capacity has
become available in
all hospitals and
many clinics.
Oxygen Saturation

Oxygen Saturation
provide important
information about
cardio-pulmonary
dysfunction and is
considered by many
to be a fifth vital sign.
Oxygen Saturation

For those suffering
from either acute or
chronic cardiopulmonary disorders,
Oxygen Saturation
can help quantify the
degree of
impairment.
