Respi () Flashcards
(124 cards)
Hollow areas between the bones in your head that help regulate the temperature and humidity of the air being inhaled.
sinuses
Tubes at the bottom of the windpipe that connect into each lung.
Brochial tubes
what are the bones and muscles of in the respiratory?
Diaphram - muscles that help the lungs pull air and push it out
Ribs - bones that protect heart and ribs
oxygen diffuses from the
capillary wall to the interstial fluid
air flow from a region of higher pressure to a region of lower pressure
air pressure variance
is determined cheifly by the radius or size of the airway through which air is flowing
air resistance
required to achiece normal levels of ventilation
increase resistance, greater than the normal respiratory effort
refers to which the lungs expland and indicates the relationship between the volume and the pressure of the lungs
Compliance
Regulation of acid base balance when inssuficient ventilation causes?
Hypercarbia
Respiratory acidemia causes
retention of excessive amount of CO2
hyper and hypocarpnia difference?
Hypercapnia, respiratory acidemia ; retention of exccessive amount of CO2
Hypocapnia, respiratory Alkalemia; Low amount of CO2 in the blood
the effectiveness of ventilation is best measured by the?
PCO2 in the ABG
explain respiratory process
- The diaphragm descends into the abdominal cavity during inspiration causing (-) pressure in the lungs.
- The (-) pressure draws the air from the area of greater pressure (THE ATMOSPHERE) into an area of lesser pressure (THE LUNGS)
- In the lungs, air passes thru the terminal bronchioles into the alveoli to oxygenate the body tissues
- At the end of inspiration, the diaphragm & intercostal muscles relax & the lungs recoil
- As the lungs recoil, pressure within the lungs becomes greater than atmospheric pressure, causing the air which now contains the cellular waste products of CO2 & H2O to move from the alveoli in the lungs to the atmosphere
- Expiration is a passive process
expiration lasts long than insipiration
Bronchial
best heard over trachea
bronchial
loud and high pitched w/ hollow quality
bronchial
ü Best heard posteriorly between scapula & anteriorly over bronchioles lateral to sternum at first & second intercostal spaces.
bronchovesicular
Inspiration = Expiration
Bronchovesicular
ü Blowing sounds that are moderate in pitch and intensity. Inspiration is equal to expiration.
Bronchovesicular
ü Created by air moving to large airways
bronchovesicular
ü Soft, low-pitched sounds that can be heard throughout the lungs, primarily when a person breathes in.
Vesivular
ü A loud, high-pitched crowing sound that is heard, usually w/o a stethoscope, during inspiration.
Stridor
caused by an obstruction in the upper airway requires immediate attention.
Stridor
usually changee or disappear w/ coughing
