Question 1

For cases with lung disease on a ventilator, since their tidal volume should be set at 6-8mL/kg…. this makes their minute volume too low, how do we fix this

Answer 1

Increase frequency (rpm) to obtain normal minute volume

Question 2

I:E ratio

Answer 2

Inspiratory: expiratory ratio

Question 3

What is I:E ratio usually (inspiration: expiration)

Answer 3

1:2

Question 4

Should inspiration or expiration be longer

Answer 4

Expiration

Question 5

PIP

Answer 5

Peak Inspiratory Pressure (how hard you squeeze the bag)

Question 6

What should PIP not go above for healthy and for diseased (peak inspiratory pressure)

Answer 6

15-20 cmH2O
30 cmH2O in diseased

Question 7

PEEP

Answer 7

Positive End Expiratory Pressure

Question 8

What does PEEP prevent (Positive end expiratory pressure)

Answer 8

Collapsed alveoli

Question 9

What is PEEP (positive end expiratory pressure)

Answer 9

Pressure in lungs above atmospheric pressure at the end of expiration

Question 10

PEEP is the pressure in lungs above atmospheric pressure at the end of expiration. What is the pressure that prevents the alveoli from collapsing

Answer 10

4-5cmH2O
