NURS 226 Oxygenation-QUESTIONS AND 100%
VERIFIED CORRECT ANSWERS!
anytime you have a pt w/ PV or cardiac issues, check
oxygenation
3 factors essential to normal function respiratory system
-integrity of the airway system
-well functioning alveolar system
-well functioning cardiovascular and blood supply
alveolar system does what
oxygenates venous blood and removes CO2 from blood
Upper airway function:
warm, filter, humidify inspired air
components of the upper airway
nose, pharynx, larynx, epiglottis
lower airway/ tracheobronchial tree function
conduction of air, mucociliary clearance, production of pulmonary surfactant
what kind of technique is used for the trachea
sterile
,components of the lower airway/ tracheobronchial tree
trachea, right and left mainstream bronchi, segmental bronchi, terminal bronchioles
cough reflex does what
help get ride of excess mucus and foreign bodies or pathogens
surfactant helps alveoli from:
reducing surface tension between alveoli preventing their collapse
lungs are compressed of what kind of tissue
elastic
lungs extend from where to where
base of the diaphragm to the apex above the 1st rib
What happens in the alveoli?
small air sacs where gas exchange happens
pleura
serous membrane lining the lungs (visceral) and thoracic (parietal)
pulmonary ventilation is what
movement of air into and out of the lungs (inspiration and expiration)
perfusion is what
, oxygenated capillary blood passes through the body through tissues
-it is the transmission of gasses
respiration aka diffusion
gas exchange between the atmospheric air in alveoli and the blood in the capillaries of O2 and
CO2 between air and blood
the diaphragm does what in ventilation
contracts and descends, lengthening the thoracic cavity so the lungs can expand and take in O2
the external ICM does what in ventilation
muscles contract, lifting the ribs upward and outward
the sternum does what in ventilation
pushed forward, enlarges the chest from front to back
the happens to the lung volume in ventilation
increased lung volume, decreased intrapulmonic pressure allow air to move from an area of
greater pressure (outside the lungs) to lesser pressure (inside the lungs)
expiration in ventilation results in what
relaxation of muscles and lungs
factors influencing diffusion
