Airway Management And Ventilation

Question 1

Atelectasis

Answer 1

Lung collapse , prevents the respiratory exchange of oxygen and carbon dioxide

Question 2

Pressure of gas in the alveoli

Question 6

Intrathoracic pressure

Answer 6

Pressure in the pleural space

Question 7

Pulmonary ventilation

Answer 7

The movement of air into and out of the lungs . Brings oxygen into the lungs and carbon dioxide out

Question 8

Tidal volume

Answer 8

The volume of air inspired or expired in a single resting breath

Question 9

External respiration

Answer 9

The transfer of oxygen and carbon dioxide between the inspired air and pulmonary capillaries

Question 10

Internal respiration

Answer 10

The transfer of oxygen and carbon dioxide between the capillary red blood cells and tissue cells

Question 11

Inspiration

Answer 11

Chest wall expands increasing the size of the thoracic cavity and expands lungs

Question 12
