HISTAMINE
|
A chemical released during inflammation that increases secretions and narrows airways
|
|
|
ANTITUSSIVE
|
Drugs that block the cough reflex by acting directly on the medullary center of the brain
|
|
|
DECONGESTANTS
|
Drugs that decrease the blood flow to the upper respiratory tract and decrease the overproduction of secretions
|
|
|
EXPECTORANT
|
Drugs that increase productive cough to clear the airways
|
|
|
MUCOLYTICS
|
Drugs that increase or liquefy respiratory secretions to aid the clearing of the airways
|
|
|
ANTITUSSIVE
Drug |
Codeine
|
|
|
Rhinitis medicamentosa
|
Reflex reaction to vasoconstriction caused by decongestants (aka rebound congestion)
|
|
|
Oral
Decongestant |
Sudafed (pseudophedrine)
|
|
|
Action of Oral
Decongestant |
Shrink the nasal mucous membrance by stimulating the sympathetic receptors in them
|
|
|
Topical Nasal Steroid Decongestant
|
Flovent (fluticasone)
|
|
|
Action of Topical Nasal Steroid Decongestant
|
Exact mechanism of action is not known
|
|
|
What is angioedema
|
rapid swelling of the dermis, subcutaneous tissue, mucosa and submucosal tissues, usualy around the mouth /eyes
|
|
|
Antihistamine Drugs
|
1st gen=Benadryl
2nd gen=Allegra Ist gen more sympathetic effect causing more drowsiness |
|
|
Action of Antihistamine Drugs
|
Selectively block the effects of histamine @ the histamine-1 receptor sites, decreasing the allergic response
|
|
|
What is UTICARIA
|
Hives
|
|
|
Action of Expectorants
|
Enhances the output of respiratory tract fluids by reducing the adhesiveness and surface tension of these fluids allowing easy movement of the less viscous secretions
|
|
|
Expectorant Drug
|
Robitussin (guafensin)
|
|
|
Action of Mucolytics
|
work to breakdown thick secretions in patients with compromised resp. systems
|
|
|
Mucolytic Drug
|
Mucomyst (acetylcysteine)
Nebulization or direct instillation into the trachea |
|
|
Cautions with mucolytics
|
can cause stomatisis (inflammation of the mucous tissue lining the mouth)
Bronchospasms, and its very irritating to the stomach |
|
|
Cheyne-Stokes Respiration
|
abnormal breathing pattern of apneic periods followed by periods of tachypnea
|
|
|
Describe COPD
|
*Air is trapped in lower respiratory tract
*Alveoli degenerate and fuse together *Gas exchange is greatly impaired |
|
|
What are
RDS and ARDS |
Respiratory Distress Syndrome and Adult Respiratory Distress Syndrome
|
|
|
Causes of ARDS
|
Severe insult to the body, such as cardiovascular collapse, major burns,etc.
|
|
|
Causes of RDS
|
The inability to maintain open alveolus related to the lack of the lipoprotein surfactant
|
