four basic components of a physical examination
1. inspection
2. palpation
3. percussion
4. auscultation
initial examination
most often performed by the attending physician to assist in making the diagnosis
subsequent examination
performed by other members of the health care team to monitor the patient's progress and assess the patient's response to treatment
facial expressions
may provide clues to the mental status of the patient
nasal flaring
a sign of labored breathing
cyanosis
bluish color of the lips and tongue that indicates inadequate oxygenation of the blood
diaphoresis
sweating which is a sign of stress and common in patients having a myocardial infarction
examination of the eyes
- pupillary reflexes tested by shining a light into the patient's eyes
- pupils should be equal, round, reactive to light, and accommodation
- dilated pupils that respond poorly to light are often a sign of neurological damage
- ptosis (drooping eyelid) is a sign of neuromuscular disease (myasthenia gravis)
examination of the neck
- assess for jugular venous distention
- JVD is a sign of right heart failure
- assess for tracheal position; the trachea may shift left or right of center when one lung collapses or when a tumor is present in the neck or upper mediastinum
- palpate for lymphadenopathy; could occur with infection or malignancy
barrel chest
an abnormal increase in A-P diameter (COPD)
kyphosis
an abnormal A-P curvature of the spine
scolliosis
an abnormal lateral curvature of the spine
kyphoscoliosis
an abnormal A-P and lateral curvature of the spine
restrictive lung disease
rapid and shallow breathing
intrathoracic airway obstruction
prolonged expiratory time
upper airway obstruction
prolonged inspiratory time
use of accessory muscles
indicates an increase in the work of breathing
abdominal paradox
occurs when the abdomen sinks inward with each inspiratory effort
respiratory alternans
occurs with diaphragm fatigue and is seen as alternating between breathing only with the chest muscles and only breathing with the diaphragm
vocal fremitus
palpating the chest while the patient repeats the words "ninety-nine"
chest palpation
- increased with pneumonia and atelectasis
- decreased with emphysema and pneumothorax
- thoracic expansion
- normally both sides of the chest expand evenly with normal or deep breathing
- one side may under expand when atelectasis, pneumonia, or a lung tumor is present
- both sides may expand poorly with emphysema
chest percussion
- done during examination to access resonance of the underlying tissue
- normal air-filled lungs normally resonate
- hyper-inflated lung and pneumothorax will demonstrate increased resonance to percussion
- decreased resonance with pneumonia, atelectasis, and pleural effusion
chest auscultations
performed with a stethescope:
- bell (most often used to auscultate heart sounds)
- diaphragm (most often used to auscultate lungs sounds)
- tubing
- ear pieces
auscultation technique
- ask the patient to breath a little deeper than normal
- start at the apices and move toward the base
- compare sounds from one side to the other
- listen for breath sounds and adventitious lung sounds
precordium examination
- inspected and palpated for normal and abnormal pulsations
- normal point of maximal impulse is created by a healthy left ventricular systole
- usually felt in the 5th intercostal space on the left at the midclavicular line
- abnormal pulsation on precordium can occur with right/left ventricular hyperophy
cardiac murmurs
caused by rapid blood flow through a narrowed valve or backflow through an incompetent valve
systolic murmur
occurs when the blood passes trough narrowed semilunar valves or backflows through incompetent AV valves
diastolic murmur
occurs when stenotic AV valves or incompetent semilunar valves
abdomen examination
- performed to inspect and palpate for distention or tenderness
- an enlarged or tender abdomen can negatively influence breathing
hepatomegaly
a large liver
ascites
an abnormal collection of fluid in the peritoneal cavity
digital clubbing
can be a serious sign of chronic cardiopulmonary disease
peripheral cyanosis
consistent with poor circulation
pedal edema
may be a sign of heart failure (COPD)
physical examination
provides reliable and important evidence regarding the patient's clinical condition
respiratory therapists
must be skilled at PE to assess the patient's condition and evaluate the effects of treatments
best evaluation
comes from looking at multiple parameters from the PE
