Oxygenation

Front 1

What is ventilation and what is required for ventilation to occur?

Back 1

ventilation is the in and out movement of air
ventilation requires:
pressure changes
adequate atmospheric 02
clear air passages
compliance and recoil
intact respiratory center and chemorecptors

Front 2

What is diffusion and what is required for diffusion to occur?

Back 2

diffusion is the movement of 02 from an area of greater concentration to an area of lower concentration
diffusion requires:
adequate atmospheric 02
healthy alveolar-capillary membrane
adequate surface area
adequate pulmonary circulation

Front 3

What is perfusion and what is perfusion influence by?

Back 3

perfusion is the adequate blood flow through the lungs
perfusion is influenced by:
position of the individual
alveolar pressure
pulmonary artery pressure

Front 4

What should be inspected during an assessment for oxygenation?

Back 4

contour/shape
movements/symmetry
color, scars
clubbing
rate and rhythm
respiratory effort/position

Front 5

What are crackles in the lungs?

Back 5

delayed opening of small airways; indicates fluid in lungs

Front 6

What are wheezes in the lungs?

Back 6

air passing through narrowed airways caused by swelling, secretions, tumors

Front 7

What is pleural friction rub?

Back 7

inflamed pleural surfaces rubbing together

Front 8

What are some interventions that could be used to facilitate respirations?

Back 8

clear fluids
humidity
position for chest expansion
breathing and coughing techniques
