Oxygentation and ventilation

Question 1

inadequate level of tissue oxygenatoin for cellular metabolism

Answer 1

hypoxia

Question 2

abnormally low atrerial oxygen tension pao2 in the blood

Answer 2

hypoxemix

Question 3

patient with hypoventilation what should be the first thing to do

Answer 3

treat underlying cause

Question 4

obesity hypoventilation syndrome can cause what respiratory issue

Answer 4

hypoventilation

Question 5

human body wil try to restrict perfusion in areas of lungs with reduced ventilation which will divert o2 to well ventilate lung regions is clal; this is best for what situation

Answer 5

hypoxic pulmonary vasoconstriction

useful for V/Q mismatch

Question 6

Treatmetn for VQ mismatch

Answer 6

start low and slow O2 and treat underlying cause

Question 7

treatment for pulmonary shuntin

Answer 7

peep, lasix, abx (pneumonia)

Question 8

normal minue ventilation

Answer 8

6-8L/min

Question 9

hypercapnia pco2

Answer 9

greater than 45

Question 10

what is one ventilatoin level that is important to identify in acute care

Answer 10

pco2

Question 11

reasons for intubation/vent

Answer 11

airway protection

Question 12

what is normal tidal volume

Answer 12

6-8ml/kg(Ideal body weight)

Question 13

what is normal peep what does it do

Answer 13

5-10
stents open airway and aveoli
greater pressure decrease blood pressure due to thoracic pressure

Question 14

what is normal pressure support, when is it used

Answer 14

5-15

pressure added on top of PEEP during inspiration (used to overocme resistance of endotracheal tube)

Question 15

what orders should be set for volume control/assist control

Answer 15

Fio2
tidal volume (ideal body )
RR
PEEP (5-10)

Question 16

SIMV difference from VC/AC

Answer 16

Patient chooses own volume and pressure support

Question 17

Orders that should be set for Pressure support or bipap

Answer 17

fio2 pressure support and peep dont set volume

Question 18

Pressure on inspiration

Answer 18

pressure support /ipap (non invasive)

Question 19

pressure on expiration

Answer 19

peep/epap (noninvaiso)

Question 20

what settings are ordered for CPAP

Answer 20

fio2 peep Or cpap

Question 21

What should be watched to prevent pressue elevatoins using VC/AC or SIMV

Answer 21

Peak pressure- the initial pressure of volume delivery to the lungs
• Goal < 40
• Reflects resistance from pt’s airways, ETT, and vent tubing
• Kink in tubing, pt biting ETT, secretions, mainstem bronchus intubation, bronchospasm

Question 22

Bucking vent releases sytokines causing organ damage is called

Answer 22

biotrauma

Question 23

Inflammation and agitation from opening and closing of alveoli.

Answer 23

atelectrauma

Question 24

Patient on vent can cause what changes to ph

Answer 24

cuase respiratory alkalosis
