Flashcards in Respiratory Support Deck (18):
1

What are the indications for Mechanical Ventilation?

Airway protection
ARDS
Shock
Acute NM Dz
Resp or Cardiac Arrest
Acute rise in IC pressure
Tachypnea or Bradypnea
Resp Acidosis

2

What are the goals of Mech Vent?

Improve Hypercapnia and Hypoxemia
Relieve suffering (effort)
Support if impaired drive
Promote survival and timely recovery
Diagnostic Tool

3

What is the difference between spontaneous breath and Positive pressure ventilation?

Whole lung involved mechanically in Spon Breath
Pos Pressure Vent only the anterior portion of the lung is ventilated and is succeptible to damage.

4

WHat are the components of Vol/Pressure targeted breaths?

Target: vol or pressure
Trigger: signal to initiate breath
Termination: signals the end of the breath

5

What are the components of mandatory breaths?

Guarunteed number and volume/pressure
Target
Controlled
Effort initiates breath.

6

What is the most common mode of mechanical ventilation?

Assist control mode
Pressure or volume targeted

7

What are the drawbacks to Assist control mode

May result in high minute ventilation and Resp alkalosis
Dynamic hyperinflation from breath stacking.

8

What is "Auto-Peep"?

Dynamic hyperinflation from breath stacking.

9

What Mode is used when you are assessing a Pt's readiness to come off the ventilator?

Spontaneous Ventilation
with just enough Pos pressure to overcome resistance of equipment.

10

How can oxygenation be improved?

Increase FiO2
Adjust Airway pressure
-PEEP(keeps lungs partially open)
-Increased inspiratory time

11

How do we choose the correct Tidal Volume for Mech Ventilation?

Based on height

12

What is the Cause of ARDS in mech Ventilation?

Too much volume in each breath

13

What are the different settings to be set on a ventilator?

Mode: VACV, PACV
RR: 16-28
Tidal Volume
PACV: PC above PEEP
PEEP: 5-10 to start
FiO2: adjust to keep SpO2 >90%

14

What is the criteria for taking someone off the ventilator?

Need has subsided
Off pressors, HR controlled, etc
Awake and interactive
Secretion control
O2 requirement
Swelling gone down(cuff leak)

15

What type of Pts need to be Re-intubation after it's taken out.

Older, weaker, Cardiac issues
worse outcomes

16

What is the difference between ECMO and CPBP?

Not on general anesthesia
The heart does all the pumping

17

What is VA ECMO?

Bypasses the heart. In Shock situations. When perfusion is inadequate.

18

What is the biggest risk in ECMO?

Bleeding
