<=Pulmonary Fibrosis/PVD=>
Athlerosclerosis
Narrowing of blood vessels
Plaque build up + Stiffening of arteries
Narrowing of arteries
Plaque grows in size
Proliferation of the intima
Turbulent blood flow
increase sheer forces of the arteries
Vascular damage
Occlusion of the lumen
Decreased blood flow
Diminished peripheral pulses
Decreased tissue healing
Thromboses
LE Intermittent claudication
Ischemia
Cool skin
Trophic changes
Decreased venous filling
Insufficient blood flow
Decreased oxygenation of tissues
Starts as pain during activity
Progressively worsens to pain at rest
medical management
Smoking cessation
Supplemental oxygen
corticosteroids
immunosuppressive or antifibrotic agents
surgical care
Lung transplnatation
Defintion
Tissue deep in the lungs becomes thick, stiff, and scarred interfering with a person's ability to breathe
Idiopathic
Cause is unknown
Interstitial Pulmonary Fibrosis
Cause is known
Common causes
Asbestos
Hard Metal Dusts
Silica Dust
Coal Dust
Grain Dust
Bird & Animal Droppings
Symptoms
Pain in feet, calves, thighs, glutes
Pale skin/trophic changes
Skin ulcerations
Diffuse weakness
Aching, burning sensation
Cool skin temperature
Decreased activity tolerance
Femoral artery bruit
Diagnosis
PFT's
Bronchoscopy
Lung biopsy
Chest X-ray
Symtoms
Shortness of breath
Persistent, dry Cough
Fatigue
Wasting
Muscle and join pain
Clubbing of fingers and toes
May be exacerbated by cold air
Depressed mood
Night Sweats
Loss of appetite
Etiology
Breathing in small particles
Particles <5 microns surpass natural defenses of nose and throat
Allergens chronically irritate the lungs
Immune response to attempt to expel particles
Repeated acute attacks cause permanent lung damage
Risk factors
Stress
Sedentary lifestyle
Smoking (>50 y/o)
Genetics
HTN
Age >70 y/o
Diabetes (>50 y/o)
Obesity
Complications
Poor skin healing
Persistent Ulcers
Gangrene
Limb amputation
Pain with exercise
Decreased activity tolerance
Pathophysiology
environmental irritant inhaled
acute neutrophilic infiltration
lymphocytic infiltration of the airways
increase of inflammatory factors
a dramatic increase in inflammation
increased vascular permeability
promoting hypoxemia and decreased lung compliance
prolonged and continuous exposure

direct cellular damage
definition
a blood circulation disorder that causes the blood vessels outside of your heart and brain to narrow, block, or spasm.
Diagnosis
Ankle-brachial index (ABI)
Ultrasound/Duplex scan
Angiography
Physical examination
R/o spinal stenosis
R/o acute embolism
R/o DVT
R/o compartments syndrome
R/o underlying neurological problem
Medical Management
Reducing platelet aggregation
Exercise
Smoking cessation
Steriods
Stent/Angioplasty
Bypass Surgery
