9 Cards in this Set

  • Front
  • Back
The reactive portion of hte lower respiratory tract includes?
bronchi
bronchioles
Cartilaginous support of the large airways are not fully developed until?

smooth muscle in these structures represents a major factor in the constriction or the airway particularly in the bronchioles
adolescence...how does this affect childrens' airways?
Define bronchitis (tracheobronchitis)?
inflammation of large airways (trachea and bronchi) which is frequently associated with URI...usually viral
What is the primary cause of bronchitis?
viral agents...
however, Mycoplasma pneumoniae is a common cause
in children older than 6 years of age...

other non-viral agents causing bronchitis include:
bacteria
fungi
allergic disorders
airborne irritants
smoking
What are the symptoms of bronchitis?
dry, hacking, nonproductive cough that worsens at night and becomes productive in 2 to 3 days
Is bronchitis severe?
no...it's a mild and self-limiting disease requiring only symmptomatic treatment
What treatment is needed for bronchitis?
basically palliative (make it more comfortable)
analgesics
antipyretics
hummidity
cough suppressants may be
useful to allow rest but
can interfere with
clearance of secretions..
takes about 5-10 days to
recover
rest
bronchodilators
increase fluid intake (encourage about 2-3 Liters
per day unless contraindi-
cated)...helps to liquify
secretions and make it
easier to expectorate
secretions)
humidify air

an antitussive might be given to give relief from coughing, but be careful not to give them so much they can't expectorate the secretions...contain codeine (Robitussin A-C, Dimetane D-C) and may cause drowsiness

antihistamines will open passageways which reduce salivary, lacrimal, bronchial and gastric and bronchial secretions

decongestants stimulate swollen blood vessels and the sinuses constrict....this causes the inflammation to go down and opens up the airways

the expectorants thin the secretions whether they can be coughed up

Guaifenesin (Robitussin) is used more often for expectorant; however it can irritate the GI tract
What is codeine (Robitussin A-C)?
opioid antitussive agent
used in combination with many
other common cough and cold
meds for treatment of
coughs
potentially addictive
can depress respirations and
CNS
contraindicated with
respiratory depression
and increased intracranial
pressure, seizure disorders
and severe respiratory
disorders

onset 30-60 min
peak 1-2 hr
duration 4-6 hr
What is guaifenesin (Robitussin)?
expectorant for management of coughs...thins difficult- to-cough up mucus in productive coughs

use with caution in individuals with asthma or respiratory insufficiency
