affecting many individuals in an area or a population at the same time

FYI

• Influenza & its complications (primarily bacterial pneumonia) are the 8th leading cause of death in the US.

• @60,000 year

H1N1

• Newly identified stain• Pandemic–(World-wide

epidemic)

Mode of transmission

• Airborne droplet• Direct contact

Influenza Statistics

• Incubation period–Short

• Onset–Rapid

• Duration–Up to a week

Influenza: S&S (local)

• Runny nose• Sore throat• Cough–Dry–Non-productive

productive– Substernal burning

Influenza: S&S (systemic)

• Higher risk of–Complications•Pneumonia•Death

Why are older adult more susceptible to complications of influenza?

• Cilia– i

• Chest muscle strength– i

• Chest wall– Stiffer

• Cough– Less effective

Assessment

Tuberculosis

• AKA–TB

Tuberculosis - FYI

• Causes more death than any other disease. 2 billion world wide, 15 million in the US

Tuberculosis - FYI

• When treated, about 90% of those with active TB survive!

Tuberculosis

• Pathophysiology– Mycrobacterium

tuberculosis– Tubercle bacillus

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 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

TuberculosisEtiology• Assoc. w/– Poverty– Malnutrition– Overcrowding– Substandard housing– Inadequate health care

• Elderly• HIV• Prison

Tuberculosis: S&S (active phase)• NOC sweats• Low grade fever• Wt loss• Chronic productive cough–Rust colored & thick

• Hemoptysis • SOB

Tuberculosis: Dx test• PPD –Mantoux skin test–> 10mm in diameter– induration – Indicates: • Latent TB

–Read• 48-72 after

– Intradermal: • 15-degrees

Tuberculosis

• Diagnostic tests– X-ray– Symptoms– Acid Fast Bacillus

Tuberculosis: Tx / Rx

• INH– isonicotinyl hydrazine – Isoniazid – Toxic to the liver

• Rifampin– Turns urine red

COPD - overview

COPD?– Chronic Obstructive Pulmonary

Disease– Broad classifications of diseases

COPDCharacteristics

• Airflow limitation • Irreversible• Dyspnea on exertion• Progressive• Abn. inflammatory response of the lungs

to noxious particles or gases

Pathophysiology

• Noxious particles of gas • Inflammatory response • Narrowing of airway

Pathophysiology

• Inflammation • Thickening of the wall of the

pulmonary capillaries

COPD

• Includes–Emphysema–Chronic bronchitis

• Does not include–Asthma

COPD - FYI

• COPD 4th leading cause of death in the US• 12th leading cause of disability• Death from COPD is on the rise while death

from heart disease is going down

COPD: Risk Factors

• Smoking• Passive smoking• Occupational

exposure• Air pollution

COPD risk factors

• #1– Smoking

• Why is smoking so bad??–↓ phagocytes–↓ cilia function–↑ mucus production

Chronic Bronchitis

• Disease of the airway• Definition:– cough + sputum production – > 3 months

Chronic Bronchitis

Pathophysiology• Pollutant irritates airway • Inflammation• h secretion of mucus • Bronchial walls thicken – Lumen narrows–plugs

Chronic Bronchitis

• Alveoli/bronchioles become damaged• ↑ susceptibility to LRI

Emphysema: Pathophysiology

• Affects alveolar membrane–Destruction of alveolar wall–Loss of elastic recoil–Over distended alveoli

Emphysema

Pathophysiology• Over distended alveoli–Damage to adjacent pulmonary

capillaries–Impaired passive expiration

Emphysema

• Damaged pulmonary capillary bed– h pulmonary pressure – h work load for right ventricle – Right side heart failure

Emphysema

• Nursing Diagnosis–Impaired gas exchange

COPD Compare and contrast

• Chronic Bronchitis is a disease of the ___________?–Airway

• Emphysema is a disease affecting the ___________?–Alveoli

C.O.P.D.

• Risk factors, S&S, treatment, Dx, Rx - same for Chronic Bronchitis & Emphysema

C.O.P.D.

Clinical Manifestation (primary)

C.O.P.D.Nrs. Assessment

• Risk factors• Past Hx / Family Hx• Pattern of development• Presence of comobidities• Current Tx• Impact

Dx tests

• ABG’s–Baseline PaO2

• Rule out other diseases–CT scan–X-ray

C.O.P.D. Medical Management

• Risk reduction– Smoking cessation!• (The only thing that slows down the

progression of the disease!)

C.O.P.D. Rx. therapy

Primary• Bronchodilators• CorticosteriodsSecondary• Antibiotics• Mucolytic agents• Anti-tussive agents

Bronchodilators• Action:–h the size of the lumen–Relieve bronchospasms–Reduce airway obstruction–↑ ventilation

Bronchodilators

• Examples–Albuterol (Proventil, Ventolin, Volmax)–Metaproterenol (Alupent)–Ipratropium bromide (Atrovent)–Theophylline (Theo-Dur)*

Glucocorticoids

• Action–Potent anti-inflammatory agent

Corticsteriods

• S/E–Na+ & H20 retention–Never D/C abruptly

Glucocorticoids

• Examples–Prednisone–Methyprednisone–Beclovent

C.O.P.D. Medical Management

• Treatment–O2• 2 L/min

–Pulmonary rehab• Breathing exercises• Pulmonary hygiene
