Oxygenation Chapter 40

Front 1

Ventilation (page 910) Test 1

Back 1

the process of moving gases into and out of the lung. Ventilation requires coordination of the muscular and elastic properties of the lung and thorax, as well as intact innervation.

Front 2

Work of Breathing Test 1

Back 2

Pressure difference between the mouth and the alveoli in relation to the rate of flow of inspired gas.

Front 3

Inspiration (page 911) Test 1

Back 3

an active process, stimulated by chemical receptions in the aorta.

Front 4

Expiration (page 911) Test 1

Back 4

a passive process that depnds on teh elastic recoil properties of the lungs, requiring little or no muscle work. Surfactant is a chemcial produced in the lungs to maintain the surface tension of the alveoli and keep them from collasping. (clients with COPD lose the elastic recoil fo the lungs and thorax.

Front 5

Compliance Test 1

Back 5

Ability of the lungs to distend or to expand in response to increased intraalveolar pressure.

Front 6

Airway Resistance Test 1

Back 6

Effort required to expand and contract the lungs.

Front 7

Diffusion Test 1

Back 7

Process for the exchange of respiratory gases in the alveoli and the capillaries of the body tissues.

Front 8

Deoxyhemoglobin Test 1

Back 8

reduced hemoglobin

Front 9

Neural regulation Test 1

Back 9

central nervous system (CNS) control of respiratory rate, depth, and rhythm.

Front 10

Chemical regulation Test 1

Back 10

Influence of carbon dioxide and hydrogen ions on the rate and depth of respirations.
