5. Respiratory Anatomy & Physiology
o The respiratory system consists of two main parts - the upper and the lower tracts
o The UPPER respiratory system consists of:
o 1. nose
o 2. mouth
o 3. pharynx
o 4. larynx
o The LOWER respiratory system consists of:
o 1. Trachea
o 2. Bronchus
o 3. Bronchioles
o 4. Respiratory unit
8. Upper Respiratory Tract
9. The Nose
o This is the first part of the upper respiratory system that contains nasal bones and cartilages
o There are numerous hairs called vibrissae
o There are numerous superficial blood vessels in the nasal mucosa
10. The Nose
o The functions of the nose are:
o 1. To filter the air
o 2. To humidify the air
o 3. To aid in phonation
o 4. Olfaction
11. The Pharynx
o The pharynx is a musculo - membranous tube that is composed of three parts
o 1. Nasopharynx
o 2. Oropharynx
o 3. Laryngopharynx
12. The Pharynx
o The pharynx functions :
o 1. As passageway for both air and foods (in the oropharynx)
o 2. To protect the lower airway
13. The Larynx
o Also called the voice box
o Made of cartilage and membranes and connects the pharynx to the trachea
14. The Larynx
o Functions of the larynx:
o 1. Vocalization
o 2. Keeps the patency of the upper airway
o 3. Protects the lower airway
15. The Paranasal sinuses

o These are four paired bony cavities that are lined with nasal mucosa and ciliated pseudostratified
columnar epithelium
o Named after their location - frontal, ethmoidal, sphenoidal and maxillary
16. The Paranasal sinuses
o The function of the sinuses:
o Resonating chambers in speech
17. The Lower Respiratory System
o The lower respiratory system consists of
o 1. Trachea
o 2. Main bronchus
o 3. Bronchial tree
o 4. Lungs- 3R/ 2L
o to the terminal bronchioles is called the conducting airway◊The trachea
o to the alveoli is called the respiratory◊The respiratory bronchioles acinus
18. The Trachea
o A cartilaginous tube measures 10-12 centimeters
o Composed of about 20 C-shaped cartilages, incomplete posteriorly
19. The Trachea
o The function of the trachea is to conduct air towards the lungs
o The mucosa is lined up with mucus and cilia to trap particles and carry them towards the upper airway
20. The Bronchus
o The right and left primary bronchi begin at the carina

o It consists of
o 1. Respiratory bronchiole
o 2. Alveolar duct
o 3. alveolar sac
o The respiratory acinus is the chief respiratory unit
o The function of the respiratory acinus is gas exchange through the respiratory membrane
o The respiratory membrane is composed of two epithelial cells
o 1.The type 1 pneumocyte - most abundant, thin and flat. This is where gas exchange occurs
o 2. The type 2 pneumocyte - secretes the lung surfactant
o A type III pneomocyte is just the macrophage that ingests foreign material and acts as an important
defense mechanism
27. Accessory Structures

Bronchiectasis are the common disorders.
104.COPD
o The general pathophysiology:
o In COPD there is airflow limitation that is both progressive and associated with abnormal inflammatory
response of the lungs to stimuli, usually smoke, particles and dust
105.ASTHMA
o The acute episode of airway obstruction is characterized by airway hyperactivity to various stimuli that
results in recurrent wheezing brought about by edema and bronchospasm
106.Asthma Pathophysiology

contractility, pulsus paradoxus
o 6. CNS manifestations: anxiety, restlessness, fear and disorientation
110.Emphysema
o There is progressive and irreversible alveolocapillary destruction with abnormal alveolar enlargement
causing alveolar wall destruction. The result is INCREASED lung compliance, DECREASED oxygen
diffusion and INCREASED airway resistance!
111.Emphysema

129.Flail Chest
o Complication of chest trauma occurring when 3 or more adjacent ribs are fractured at two or more
sites, resulting in free-floating rib segments.
130.Flail Chest
o Chest wall is no longer able to provide the bony structure necessary to maintain adequate ventilation;
consequently
o the flail portion and underlying tissue move paradoxically (in opposition) to the rest of the chest cage
and lungs.
131.Flail Chest
o The flail portion is sucked in on inspiration and bulges out on expiration.
o Result is hypoxia, hypercarbia, and increased retained secretions.
o Caused by trauma (sternal rib fracture with possible costochondral separations).
132.Flail Chest
o PATHOPHYSIOLOGY
o During inspiration, as the chest expands, the detached part of the rib segment (flail segment) moves in
a “paradoxical” manner
o The chest is pulled INWARD during inspiration, reducing the amount of air that can be drawn into the
lungs
o The chest bulges OUTWARD during expiration because the intrathoracic pressure exceeds
atmospheric pressure. The patient has impaired exhalation
133.Flail Chest
o This paradoxical action will lead to:
 Increased dead space
 Reduced alveolar ventilation

 Decreased lung compliance
 Hypoxemia and respiratory acidosis
 Hypotension, inadequate tissue perfusion can also follow
134.Flail Chest
o 1. Severe dyspnea; rapid, shallow, grunty breathing; paradoxical chest motion. The chest will move
INWARDS on inhalation and OUTWARDS on exhalation.

138.Pneumothorax
o Types
o a . Spontaneous pneumothorax : the most common type of closed pneumothorax; air accumulates
within the pleural space without an obvious cause. Rupture of a small bleb on the visceral pleura most
frequently produces this type of pneumothorax.
139.Pneumothorax
o Types
o b. Open pneumothorax : air enters the pleural space through an opening in the chest wall; usually
caused by stabbing or gunshot wound.
140.Pneumothorax
o Types
o c. Tension pneumothorax : air enters the pleural space with each inspiration but cannot escape;
causes increased intrathoracic pressure and shifting of the mediastinal contents to the unaffected side
(mediastinal shift ).
141.Pneumothorax
o 1. Sudden sharp pain in the chest, dyspnea, diminished or absent breath sounds on affected side ,
tracheal shift to the opposite side (tension pneumothorax accompanied by mediastinal shift)

o b. Pleural biopsy may reveal bronchogenic carcinoma
o c. Thoracentesis may contain blood if cause is cancer, pulmonary infarction, or tuberculosis; positive
for specific organism in empyema.
o Nursing interventions: In general:
o 1. Assist with repeated thoracentesis.
o 2. Administer narcotics/sedatives as ordered to decrease pain.
o 3. Assist with instillation of medication into pleural space (reposition client every 15 minutes to

180.Pulmonary Embolism
o This refers to the obstruction of the pulmonary artery or one of its branches by a blood clot (thrombus)
that originates somewhere in the venous system or in the right side of the heart.

legs.
o Causes
o Fat embolism. Air embolism
o Multiple trauma
o PVD’s
o Abdominal surgery
o Immobility
o Hypercoagulability
o PATHOPHYSIOLOGY
o The thrombus that travels from any part of the venous system obstructs either completely or partially .
Then the lungs will have inadequate blood supply, with resultant increase in dead space in the lungs
o Gas exchange will be impaired or absent in the involved area
o PATHOPHYSIOLOGY
o The regional pulmonary vasculature will constrict causing increased resistance, increased pulmonary
arterial pressure and then increase workload of the right side of the heart.
o PATHOPHYSIOLOGY
o When the work of the right side of the heart exceeds its capacity, right ventricular failure will result,
leading to a decrease in cardiac output followed by decreased systemic perfusion and eventually,
SHOCK
