Q

If loop is shifting towards a pressure access, towards increased PIP what is happening to compliance as airway pressure gets higher?

17
Q

Needs to be intubated for a short amount of time, what mode should be used

A

Synchronized Intermittent Mandatory Ventilation (SIMV)

18
Q

SIMV is used for

A
  • weaning
  • do some of the breathing on their own
  • prevents breath stacking
19
Q

pt trigger breath

A

starting the breath

20
Q

examples of triggers

A
  • pt
  • cycling
21
Q

examples of cycling breath

A
  • Time cycle, after a certain amount the breath cycles (end)
22
Q

High Vt increases

A

Peak Inspiratory Pressure (PIP)

23
Q

PIP should be less than

A

30

24
Q

Increased PIP can be b/c of

A

secretions

25
Q

If pt is MVC trauma with neurologic problems, and needs to be sedated what mode will put pt on

A

Continuous Mandatory Ventilation (CMV)

26
Q

Pressure control setting is used to control

A

pressure and allows pt to choose their own volume

27
Q

Pt has to be spontaneous breathing what mode will you use

A

CPAP

27
Q

What are CPAP parameters

A
  1. pressure support ventilation (SBT, CPAP trial)
  2. PEEP
    3.FIO2 (low setting)
28
Q

Positive end expiration pressure (PEEP) can aid to help with

A

oxygenation (increase pao2); keeps alveoli open

29
Q

If BP is low (hypotension) caution with increasing

A

PEEP

30
Q

Bigger tube equals

A

decreased airway resistance

31
Q

If pt has a lot of sedation and not waking up, what can be issue with pt from stopping them from coming off sedation?

A

Renal issue

32
Q

What is the difference between IMV and SIMV

A

They both are able to take breaths in-between mandatory breaths

IMV- can breath stack
SIMV- cannot breath stack

33
Q

Sometimes pts with high Intracranial Pressures (ICP) sometimes we will put them in a

A

Alkolotic state (rr high), b/c it allows reduce of intracranial pressure b/c it restricts blood vessels.

34
Q

White on X-ray

A

Fluid
Calcification

35
Q

Black on X-ray

A

Air
Hyperinflation

36
Q

Altered Mental Status (AMS) think

A

neurological problem

37
Q

Sleep apnea

A

sleep disorders

38
Q

Respiratory paralysis, what type of pt could it be

A

spinal cord or mvc

39
Q

If Volume cycled, what’s making that breath

A

volume

40
Q

If time cycled, what’s making that breath

A

time

41
Q

If pressure triggered, what’s starting breath

A

pressure
