Q

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

A

lungs become less compliant (decrease compliance)

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

24
Q

Increased PIP can be b/c of

A

secretions

25
If pt is MVC trauma with neurologic problems, and needs to be sedated what mode will put pt on
Continuous Mandatory Ventilation (CMV)
26
Pressure control setting is used to control
pressure and allows pt to choose their own volume
27
Pt has to be spontaneous breathing what mode will you use
CPAP
27
What are CPAP parameters
1. pressure support ventilation (SBT, CPAP trial) 2. PEEP 3.FIO2 (low setting)
28
Positive end expiration pressure (PEEP) can aid to help with
oxygenation (increase pao2); keeps alveoli open
29
If BP is low (hypotension) caution with increasing
PEEP
30
Bigger tube equals
decreased airway resistance
31
If pt has a lot of sedation and not waking up, what can be issue with pt from stopping them from coming off sedation?
Renal issue
32
What is the difference between IMV and SIMV
They both are able to take breaths in-between mandatory breaths **IMV- can breath stack** **SIMV- cannot breath stack**
33
Sometimes pts with high Intracranial Pressures (ICP) sometimes we will put them in a
Alkolotic state (rr high), b/c it allows reduce of intracranial pressure b/c it restricts blood vessels.
34

Fluid Calcification
35
Black on X-ray
Air Hyperinflation
36
Altered Mental Status (AMS) think
neurological problem
37
Sleep apnea
sleep disorders
38
Respiratory paralysis, what type of pt could it be
spinal cord or mvc
39
If Volume cycled, what's making that breath
volume
40
If time cycled, what's making that breath
time
41
If pressure triggered, what's starting breath
pressure
