Oxygenation and Perfusion Flashcards
what is the number 1 preventable cause of lung disease and death
smoking
oxygenation
properly functioning alveolar capillary membrane
oxygenation does what to venous blood
oxygneates
oxygenation removes what from the blood
carbon dioxide
COPD is an oxygenation or ventilation issue
oxygenation
oxygenation is basically
diffusion
ventilation
ability to transport air to and from lungs
asthma would be a oxygenation or ventilation issue
Ventilation
obstructions would be an oxygenation or ventilation issue
ventilation
what two things need to occur to get proper levels of O2 to the tissues
oxygenation and ventilation
upper airway function
warm, filter, humidify
lower airway function
conduction of air, mucocillary clearance
alveolar capillary membrane function
gas diffusion
factors affecting pulmonary functioning
levels of health
medications
lifestyle
environment
how would left sided heart failure affect the lungs
buildup and back flow into lungs
how would deficiency in nutrition affect pulmonary functioning
leads to muscle wasting which leads to the diaphragm not being able to work as good as possible which leads to increased workload
how would anemia affect oxygenation
not enough hemoglobin to pick up oxygen
how do opioids affect pulmonary function
depresses respiratory function
how does obesity affect pulmonary function
more effort
normally hypo ventilators
what are some environment related things that can affect pulmonary function
pollution
secondary smoke
fumes
increased work of breathing would cause decreased oxygenation or decreased ventilation
decreased oxygenation
decreased gas exchange would cause decreased oxygenation or decreased ventilation
decreased oxygenation
why is increased work of breathing bad
expiration becomes active
why is decreased gas exchange bad
decreased number of capillaries
and/or
decreased inspiratory lung volumes
would an ineffective cough cause cause decreased oxygenation or decreased ventilation
decreased ventilation
would drier mucous membranes cause decreased oxygenation or decreased ventilation
decreased ventilation
increased risk for aspiration due to decreased gastric mobility would cause decreased oxygenation or decreased ventilation
decreased ventilation
would impaired mobility cause decreased oxygenation or decreased ventilation
decreased ventilation
medications that decreased ventilation cause decreased oxygenation or decreased ventilation
decreased ventilation
why would impaired mobility cause decreased ventilation
pooling of secretions
is tissue and airways becoming more rigid cause decreased oxygenation or decreased ventilation
decreased ventilation
why would airways becoming more rigid cause decreased ventilation
diaphragm moves less efficiently which leads to less air exchange
what is included in a focused pulmonary interview
how is your breathing
do you smoke
do you have any pets
have you travelled recently
do you experience difficulty breathing or fatigue? if so what causes this
where do you sleep?
who does the shopping?
do you vacuum?
what type of work do you or did you do?
any chest pain?
do you have a cough
- if yes= how long? Is anything coming up?
- if yes= what color?
have you ever been exposed to fumes
is there a position in which your breathing is most comfortable?
do you have any allergies?
why would we ask
- how is your breathing?
why would we ask
- how is your breathing?
so we know patient normal
how do we measure smoking and years
PACK YEAR
how do we measure pack years
number of packs you smoke a day x years you’ve been smoking
say you smoke 3 packs a day for 5 years, what’s the pack years
15 pack years
why would we ask
- do you have any pets
any allergies or possible allergies
why would we ask
- have you traveled recently
travel to any countries with an increase in respiratory diseases
why would we ask
- where do you sleep
tells us if the patient is able to get to the bedroom especially if it is a two story home
why would we ask
- who does the shopping
know activity level
why would we ask
- do you vacuum
vacuuming requires the lung accessory muscles so we get a firm understanding if the accessory muscles are being used for breathing
why would we ask
- what type of work do you do or did you do?
pollutions and fume exposure
ex: farmers are exposed to fertilizers and pollutions
why would we ask
- have you ever been exposed to fumes
restrictive diseases could come from fume exposure
pulmonary ventilation inspection
respiratory rate
depth
pattern
work of breathing
using accessory muscles
chest symmetry
skin color
surgical scars
why should we inspect for scars on the back
incase part of or whole part of the lung was removed
what can we auscultate for the lungs
adventitious sounds
what are the 3 adevtnious sounds
- wheezes
- crackles
- rhonchi
what are wheezes frequency
high pitch
