Atelectasis

• Definition– Closure or collapse of

alveoli

Atelectasis: Pathophysiology

• Can occur as a result of alveolar ventilation or

• any type of blockage • that impedes the

passage of air to and from the alveoli

Atelectasis: Etiology

• #1 post-op• secretions or mucus

plug• Chronic airway

obstruction– i.e. lung CA

• Excessive pressure on the lungs

Atelectasis: Risk Factors

• Altered breathing patterns

• Retained secretions• Pain• LOC• Immobility• Prolonged supine

position• Post-op

Atelectasis: Clinical Manifestations

2003– 8098 people worldwide

dx with SARS in 2003– 774 died!

SARS

• Mode of transmission– Respiratory droplet

• When infected person coughs or sneezes

• The droplet gets on another's mucous membranes or

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

SARS

S&S• Initial– High fever– H/A– Body aches– Mild resp. symptoms– After 2-7 days

• After 2-7 days– Dry cough– Progressive hypoexmia

– Pneumonia

• 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

• Pathophysiology– Mycrobacterium

tuberculosis– Tubercle bacillus

Question?

• TB is caused by a(n)?A. BacteriaB. VirusC. FungusD.ParasiteE. 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

Tuberculosis

• 5-10% become active• Only contagious when

active• Primarily affect lungs

but…– Kidneys– Liver– Brain– Bone

Tuberculosis

Etiology• Assoc. w/

– Poverty– Malnutrition– Overcrowding– Substandard housing– Inadequate health care

• Elderly• HIV• Prison

TuberculosisS&S (active phase)• NOC sweats• Low grade fever• Wt loss• Chronic productive cough

– Rust colored sputum– Thick

• Hemoptysis • SOB

Tuberculosis

Diagnostic exams• PPD – Mantoux skin test– > 10mm in diameter– induration – Indicates:

• Latent TB – Read

• 48-72 after – Intradermal: 15-degrees– Do not rub

Tuberculosis

• Diagnostic tests– X-ray

• Cavities or lesions

– Symptoms– Acid Fast Bacillus

TuberculosisTreatment• 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 MEDICATIONYour 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, long-term 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

Pathophysiology:• “Accumulation of air

or gas in the pleural cavity”

• Left-sided pneumothorax (on the right side of the image) on CT scan of

the chest with chest tube in place.

http://en.wikipedia.org/wiki/Computed_tomography

Pneumothorax

Anatomy Review- Pleural cavity

• Visceral pleura– Encases lungs

• Pleural space/cavity– Area between pleura– Contains fluid (4ml)– Fluid prevents friction– Fluid circulated by…

• lymph system• Parietal pleura

– Lines chest wall

Pneumothorax

Anatomy review - Breathing• Diaphragm & 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 ()

• air exhaled

Pneumothorax

• 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

Pneumothorax

Classifications of pneumothorax

• Spontaneous pneumothorax– with out injury– Air enters the pleural

cavity via the airway– Farther classified as:

• Primary• Secondary

Pneumothorax

Spontaneous (Primary) Pneumothorax

• Pt. with no known lung disease.

• D/T a rupture of a bulla in the lung.

• Most often tall, thin men between 20 and 40 years old.

Pneumothorax

Spontaneous Secondary Pneumothorax

• occurs in pt. with known lung disease– most often COPD

• Other lung diseases commonly assoc. with– Tuberculosis– Pneumonia– Asthma– cystic fibrosis– lung cancer

• Often severe & life threatening

Pneumothorax

• Traumatic Pneumothorax– D/T injury to the chest

wall– Further classified as

Open or closed

Pneumothorax

Open Pneumothorax• Air enters pleural cavity via

outside• A free communication

between the exterior and the pleural space as through an open wound– blowing wound– sucking wound

• may be caused by a penetrating injury– stab wound,– gunshot wound– impaled object

Pneumothorax

Closed pneumothorax• Air enters the pleural

cavity via lungs• D/t/ blunt chest

trauma– Car crash– Fall– Crushing chest injury

Pneumothorax

Iatrogenic pneumothorax• D/T procedure /

treatment

Pneumothorax

Tension Peumothorax• air accumulates in the

pleural space with each breath.

• The remorseless increase in intrathoracic pressure

• massive shifts of the mediastinum away from the affected lung

• compressing intrathoracic vessels

• cardiovascular collapse

Pneumothorax

Tension Pneumonthorax• a piece of tissue forms

a one-way valve that allows air to enter the pleural cavity but not to escape, overpressure can build up with every breath

Pneumothorax

Etiology / Contributing factors• Spontaneous

– Lung disease - COPD– Tall, thin men

• Traumatic– A penetrating chest wound – Barotrauma

• scuba divers• Iatrogenic Pneumothorax

– * insertion of a central line – * thoracic surgery – * thoracentesis – * pleural or transbronchial

biopsy.

Question?

A client who has been on a ventilator for two days experiences acute respiratory distress 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.

• A patient is being treated with chest tubes because of a pneumothorax. The nurse recognizes that chest tubes may be used to:– Prevent pleural irritation– Regain positive intra-pleural pressure– Remove air from the intra-pleural space– All of the above– None of the above
