Atelectasis
•
Definition
–
Closure or collapse of
alveoli
Atelectasis: Pathophysiology
• Can occur as a result of
i alveolar ventilation
or

passage of air to and
from the alveoli
Atelectasis: Etiology

• h secretions or mucus
plug
• Chronic airway
obstruction
– i.e. lung CA

– 8098 people worldwide
dx with SARS in 2003
– 774 died!
SARS
• Mode of transmission
– Respiratory droplet
• When infected person
coughs or sneezes

another's mucous
membranes or
• On a surface that is touch
by another and then they
touch their own mucous
membranes

Tuberculosis
• AKA
– TB
– Consumption
Tuberculosis - FYI
• Causes more death than any other disease. 2
billion world wide, 15 million in the US
Tuberculosis - FYI
• When it becomes active it kills 60% of those
not treated. Amounts to about 3 million
deaths each year. In the US about 20,000 TB
cases become active each year.
Tuberculosis - FYI
• When treated, about
90% of those with
active TB survive!

tuberculosis
– Tubercle bacillus
Question?
• TB is caused by a(n)?
A. Bacteria
B. Virus
C. Fungus
D.Parasite
E. Little green bugs!
Tuberculosis
Pathophysiology
• Mode of transmission
– Air-borne
•  alveoli
• Multiplies in alveoli
Tuberculosis
• Immune response phase
– Macrophages attack TB
– TB has waxy cell wall that protects it from
macrophages
– Immune system surrounds the infected
macrophages
– Forms a Lesion
– Called a Tubercle
Tuberculosis
• Dormant /latent phase
– Contagious?
• No
– Symptomatic?
• No
– PPD?
• positive
– chest x-ray?
• Negative
Tuberculosis
• Active phase
– If an infected person has a weakened immune
system, 
– the TB escapes and infects the body

active

– Read
• 48-72 after
– Intradermal: 15-degrees
– Do not rub
Tuberculosis
• Diagnostic tests
– X-ray
• Cavities or lesions
– Symptoms
– Acid Fast Bacillus
Tuberculosis
Treatment
• INH
– isonicotinyl hydrazine
– Isoniazid
– Toxic to the liver
• Rifampin
– Turns urine red
• Streptomycin
– Causes 8th cranial nerve damage
– Acoustic nerve
Tuberculosis: treatment
• Rx toxic to liver and
CNS
• Must take >6months
• Usually take > one at a
time
• Not contagious after
2wks of treatment
• INH - TUBERCULOSIS MEDICATION
Your positive skin test reaction shows that you
have been exposed to tuberculosis at some
time in the past. The tuberculosis germ is still
present in your body. If your chest x-ray is
normal, you do NOT have active TB disease.
• TB germs can live in your body without making you
sick. This is called TB infection, and this is what you
have. Your immune system has trapped the TB
germs. However, if your immune system or body
defenses go down, as can happen with stress, longterm illnesses, old age, or other stressors such as
alcohol abuse, the TB germs may multiply and
develop into active TB disease. TB germs can affect
other organs besides the lungs.
• We recommend that you take preventive medicine
now, before your TB infection becomes active TB
disease. This medicine, taken every day for six or
nine months, will kill the TB germs in your body so
that you will not develop active TB disease. The
medicine you will be taking is Isoniazid - also called
“INH.” This medicine may deplete your body’s stores
of vitamin B6, so you will also be given additional
vitamin B6, to counteract possible side effects from a
lack of this vitamin.

Pneumothorax
Anatomy review - Breathing
• Diaphragm i & accessory
muscles move outward 
• Negative pressure in the
thoracic cavity 
• Negative pressure pulls air
into the lungs via the nose
and mouth
• Diaphragm & accessory
muscle relax (h) 
• air exhaled

•
If the visceral pleural is
perforated or the chest
wall & parietal pleural
are perforated
– air enters the pleural
space 
– negative pressure is
lost 
– Lung on the affected
side collapses

accompanied by distended neck veins. The
best action of the nurse is to:
A. hand ventilate the client.
B. prepare for chest tube insertion.
C. call the physician immediately.
D. perform emergency chest decompression.
• The question is asking what the nurse should do when a client
on a ventilator has these symptoms. When acute respiratory
distress occurs along with neck vein distension, cyanosis and
tracheal shift are evident, a tension pneumothorax has
probably occurred. The client should be removed from the
machine and ventilated by hand. Then the physician should
be notified (option c). Equipment for chest tube insertion
should be gathered (option b) so it will be ready for
immediate use by the physician. Emergency chest
decompression (option d) should only be attempted after
specific training and if the physician will be delayed.
