Respiratory Disease Flashcards
common issues regarding ventilation
airway patency , muscle issues
common issues regarding gas exchange
number of alveoli, alveolar wall fibrosis
how many lobes do the left and right lung have
left - 2
right = 3
costophrenic angles
bottom corners of lungs where ribs meet diaphram
type 2 respiratory failure
ventilation inadequate to deliver enough o2 to blood
muscles used in ventilation
diaphram , internal and external intercostals, accesory muscles e.g sternocleidomastoid , pectoralis major
emphysema
codition seeing damage and destruction of alveoli causing shortness of breath as less gas exchange occuring
type 1 respiratory failure
gas exchange failure
stridor
noise on inspiration
dyspnoea
difficulty breathing
inhalation method of administration
topical to bronchial tree airway walls
as airflow speed reduces particles drop from air onto walls to be absorbed
why are mast cell granulation inhibitors used to treat ventilation issues
mast cell granulation causes bronchoconstriction
meter dosed inhaler
classic asthma inhaler
relies on co ordinated disposal of drug and breath to carry it to oropharynx
breath activated device
spin and turbo inhalers , drug is picked up as breath moves through device
nebuliser
converts medication to a fine mist and drastically improves delivery to airways
spacer
used with mdis, dont need to co ordinate breath with drug release
B - agonists as a respiratory treatment
Used to treat/ prevent bronchoconstriction
can be short acting or long acting
anticholinergics as a respiratory treatment
assist bronchial dilation
grey inhaler
corticosteroids as a respiratory treatment
reduce inflammation in bronchial walls , reduce mucosal oedema and reduce mucous secretion
brown inhaler
e.g beclomethasone
short acting beta agonists
rapid onset but short duration , used to treat a current episode
blue inhaler e.g salbutamol
long acting beta agonists
slow onset but long duration , used as prevention
green inhaler e.g salmeterol
Always used alongside an inhaled corticosteroid
