8. What is respiration? process of gas exchange, movement of oxygen from the atmosphere to
the bloodstream and the movement of CO2 from the bloodstream to the
atmosphere




9. What is compliance? measure of elasticity of the lungs and thorax




10. When is compliance af- When decreased in states of inflammation, it becomes difficult to inflate
fected? our lungs/ When there are fluid filled situations (ARDS, pulmonary edema)
it also gets affected.

11. What is elastance? reflects resistance to change the shape when machical load applies




12. How does compliance Lung compliance is inversely related to elastance, which is also known as
relate to elastance? elastic resistance or elastic recoil. So, a patient with low lung compliance
will have a relatively stiff lung and, therefore, higher elastance.

14. Why would we stimu- When we are looking at a pt who is requiring advanced airway support,
late the carina? stimulating the carina is one mechanism we can look at to assess a
patient's ability to protect their airway

15. How do you stimulate Elicit stimulation with a suction catheter should under normal circum-

16. What is an important The angle of the left differs significantly from the right
fact about the left vs
right bronchus?

17. What is the angle of more acute angle
the left bronchus?




18. What is the angle of more straight - Higher risk of aspiration to the right side than to the left;
the right bronchus? also a risk of accidentally intubating the right tube (assess this by checking
bilateral ventilation)
