Question 1

Normal V/Q ratio (ventilation perfusion)

Answer 1

0.8–4L in/ 5L out

Question 2

Left shift of oxyhemoglobin dissociation curve

Answer 2

affinity increases for 02 so when gets to tissue it wont drop off

Question 3

Right shift on oxyhemoglobin dissociation curve

Answer 3

affinity is weak so drop off quicker

anything that increases your metabolic rate will shift cure to the right

Question 4

things that shift the oxyhem curv to the left

Answer 4

decrease paco2
decreased temp
increased ph

Question 5

things that shift oxyhem curv to the right

Answer 5

increased paco2
increased temp
decreased ph

Question 6

heliox used for

Answer 6

obsturcitve airway diseases–lighter density than o2 so can get past obsturctions

Question 7

nio2

Answer 7

used in Pulm HTN, pulm vasodilator–start at 20 and move down, monitor methemoglobin

decreases intermpulmonary shunting

Question 8

minute volume

Answer 8

RR x TV

Question 9

1 hrz on oscilator =

Answer 9

60 breath per minute

Question 10

amplitude on oscilator contorls

Answer 10

TV–if want to remove more co2 go down on amp

Question 11

c02 levels indicate

Answer 11

ventilation and airflow

Question 12

ways to correct co2 levels

Answer 12

adjust rate, PIP, and tidal volume

Question 13

pa02 levels indicate

Answer 13

oxygenation and o2 delivery

Question 14

ways to ajust pao2

Answer 14

adjust peep (FRC) and fio2

Question 15

what peep indicates need for oscilator

Answer 15

14

Question 16

Normal mixed venous 02 sat

Answer 16

65-80%

Question 17

If you have a high mixed venous 02 (SVO2) it means

Answer 17

you have high o2 delivery (increased fio2)

and you have a low o2 demand (hypothermia, paralysis, anethesisa, spesis)

Question 18

if you have a low mixed venous 02 it means

Answer 18

you have low 02 delivery (anemia, hemorhage, hypoxia, suctioning, low caridac output, hypovolemia, shock, arrthmyias)
increased o2 demand (increased temp, pain, shivering, seizures)
