Q

What is included in a vent check?

A
  • modes
  • sensitivity
  • auto-PEEP (must be measured. may be difficult to trigger if auto-PEEP)
  • accessory muscle usage - ex flow
  • can increase flow to shorten IT. change mode to allow for more spontaneous breaths
  • if auto-PEEP and you increase PEEP, plat/peak will not change (or if PV, VT won’t change)

Q

What should you keep in mind during a vent check?

A
  • IMV and demand flow. watch triggering
  • VE, VT and F - measure by hand
  • correcting for tubing compliance
  • PB 7200/840 corrects for tubing compliance
  • set volume = delivered volume

Q

What are the top reasons a machine will not cycle?

A
  • sensitivity set too low
  • auto-PEEP
  • high bias flow
  • abdominal paradox
20
Q

What does “alveolar ventilation is not ventilation” mean?

A

just because air is going in and out doesn’t mean it’s in contact with alveolus

21
Q

Normal alveolar ventilation

22
Q

Normal CO2

23
Q

Normal minute ventilation

24
Q

Normal dead space

25
What does it mean if someone's CO2 was 41 one day and 52 the next?
his dead space went up
26
What should you keep an eye on when monitoring airway pressure?
- peak inspiratory pressure - plateau pressure - Raw - EEP - MAP - pressure limit - low pressure alarm - checking for leaks
27
What should plateau pressure always be below?
30
28
What is mean airway pressure?
the average pressure of an airway
29
What is plateau pressure?
no airflow
30
What is the difference between plateau and mean airway pressures?
plateau pressure is usually higher because it only includes the inspiratory phase while the mean airway pressure includes both inspiratory and expiratory phases
31
What is the purpose of the five-step protocol?
to minimize over inflation leading to tracheal necrosis
32
What is the first step of the five-step protocol?
the minimal leak technique (MLT) should be used whenever possible
33
What is the second step of the five-step protocol?
a reasonable MLT should be established, one in which only 50 to 100 mL of VT is lost during inspiration. for example, in vc-cmv with a 600 mL VT setting and delivery, the VTe is 500-550 mL
34
What is the third step of the five-step protocol?
a high-volume low-pressure cuff should not require more than 5 mL for inflation. if it does, the tube is probably too small
35
What is the fourth step of the five-step protocol?
if a minimal leak cannot be maintained with a cuff volume of less than 5 mL then the practitioner should make sure that the intracuff pressure is less than 25 mmHg and that the cuff-to-tracheal diameter ratio checked on chest radiograph is 1:1.5 or less
36
What is the fifth step of the five-step protocol?
if steps 1 through 4 cannot be achieved, follow-up evaluation of the patient for tracheal stenosis should be performed for at least 1 year after discharge
37
What should you keep an eye on when monitoring compliance?
- static compliance - dynamic compliance - airway resistance - bedside measuring of press-volume curve
38
What does it mean if there are no changes in compliance and resistance when measuring the pressure-volume curves?
it's not the lung
39
What does it mean when there is a decrease in compliance?
large change in pressure but no change in volume
40
What does compliance mean?
how much work 1 cmH2O is doing. if it is distending one at 20 and another at 30, the second lung has better compliance
41
What happens when there is a decrease in dynamic compliance in PCV?
pressure will not change but VT delivery will fall
42
What happens when there is a decrease in dynamic compliance in CMV?
VT will not change but pressure will fall
43
When you change static compliance, you will also change ___
dynamic compliance
44
What does it mean when there is no change in peak or plateau pressures?
no change in airway resistance since peak-plat = Raw
45
What happens when plateau stays the same but peak changes?
change in airway resistance
46
If plateau stays the same, there is no change in what?
static compliance
