respiratory specific Flashcards
(99 cards)
of lobes on the left and right lungs
2 left
3 right
what direction does the diaphragm move during inhalation
moves down, pressure drops
diaphragm moves in what direction during exhalation
moves up, pressure increases
ribs 1-7
true ribs; attached
ribs 8-10
false ribs
ribs 11 and 12
floating ribs– especially dangerous if fractured– can puncture organs
three main spaces
right space, pleural space, mediastinum
visceral membrane
inner membrane of the lung
parietal membrane
outer membrane of the lung
potential space
the potential space between the parietal and visceral membrane that are supposed to be stuck together at all times
normal pressure in the potential space
negative
pneumothorax
a condition where air builds up in the potential space of the lung
pleural effusion
increase of fluid buildup – lung will collapse
major organs in mediastinum
heart, esophagus, trachea, thymus
what are trachea
cartilage rings to keep airway open
bronchi
carina (source of cough reflex)
bronchioles
instead of cartilage rings, has smooth muscle encircling it
alveolar ducts
small passage ways in the lungs that connect bronchioles to alveolar sacs
what are alveoli
tiny air sacs at the end of bronchioles, and are surrounded by capillaries; where gas exchange happens
right mainstem bronchus
- larger and more vertically angled
- increased risk for aspiration
- inserted ETT too far if it goes in because then only one side gets air
intercostal retractions
skin sinks between the muscles of the ribs during inhalation. common in babies and children– indicates reduced air pressure
substernal retractions
when the skin sinks below the breastbone during inhalation– indicates difficulty breathing
normal respirations
12-20/min in adults
use of accessory muscles indicates?
labored or increased WOB
