Oxygenation Flashcards
what is the highest single preventable factor in decreasing lung disease?
cigarette smoking
smoking has been historically ____?
embedded in culture
more smokers in rural or urban cities?
urban
what does smoking do to lungs?
breaks down and destroys alveolar capillaries and tissue- decreases life expectancy
what is EVALI?
e-cig product use associated with lung injury
what is oxygenation?
properly functioning alveolar capillary membrane
what blood does oxygenation oxygenate?
venous
what does oxygenation remove from blood?
carbon dioxide
what is ventilation?
ability to transport air to and from lungs
*can’t bring air in
COPD oxy or vent issue?
oxygenation issue
asthma oxy or vent issue?
ventilation issue
obstructions vent or oxy issue?
ventilation issue
which is required to get proper levels of O2 to the tissues?
both oxygenation and ventilation
function of upper airway?
warm, filter, humidify air
*not actually a function, has to be provided
function of lower airway?
conduction of air, mucocilliary clearance
*helps clear airways
what impairs mucocilliary fibers moving air?
anesthesia
function of alveolar capillary membrane?
gas diffusion
factors affecting pulmonary functioning?
-levels of health
-medications (like analgesics)
-lifestyle
-environment
examples of lifestyle factors?
sedentary- stasis of secretions
pollution
smoking
work environment
obesity- hypoventilators
pets
what issue do cardiac and lung problems cause?
respiratory
affect of chronic resp issue?
muscle wasting - includes diaphragm (not working as well) leads to increased workload
anemia affect?
low RBC=low oxygen (hemoglobin carries oxygen) resp rate increases to compensate
how would left sided heart failure affect the lungs?
build up and back flow into lungs
opioid effect?
depressed respiratory system
