Definition
•Hyperactivity of the airways leading to Bronchoconstriction & Bronchospasm
•Increased production of thick tenacious mucus
Etiology
•Extrensic: Allergens (pollen, mold)
•Intrensic: Everything else (exercise, cold air)
Signs
Increased RR, HR, CO, BP
Symptoms
Dyspnea, Increased WOB
Observation/ Presentation
•Prolonged (forceful) expiration
•Cyanotic (severe)
Palpation
Decreased tactile fremitus
Percussion
Hyper resonant
Auscultation
•Wheezing (expiration)
•If diminished or absent (serious)
ABG
•Decreased PaCO2 (due to hyperventilation)
•If PaCO2 rises up suddenly to normal = serious
Sputum
Thick, tenacious
Secondary conditions
Pulsus paradoxus (sys BP drops 10-20torr during inspiration)
CXR
•Not significant
•Slightly darker & increased capacity due to air trapping
PFT
•Increased Raw
•Decreased Flow, Low Peak Flows
•Increased RV, FRC
•PFT's may be normal between exacerbations
Labs
•PFT
•Spirometry
•ABG
•CBC
Diagnosis
•Blood test
•PFT
•Classification
Treatment
•Asthma Action Plan
•Manage, Control, Prevent
•Steroids, Bronchodilators
•Mast cell inhibitors, Antileukotrines
4 lines for asthma treatment
•1st line: Maintenance
•2nd line: Rescue
•3rd line: Emergency
•4th line: (last line) Oral/ IV steroids, Xanathines, Heliox, Magnesium Sulfate, Mechanical ventilation
Status Asthmaticus
When asthma patient is not responding to conventional treatment
Prognosis
With proper treatment and monitoring, asthma can be controlled and the patient can live a normal lifestyle
