NEO: invasive mechanical ventilation of pediatrics (0/7)

3 main goals of mechanical ventilation

1. safety (ensure adequate gas exchange, provide lung protection)

2. comfort (max synchrony, ensure adequate work by vent in response to work support demand by the pt.)

3. liberation (minimize duration of vent + risk of adverse events)

clinical indications for conventional ventilation

1. inadequate/absent RR

2. increased WoB

3. high O2 needs

4. severe resp. acidosis

5. mod-severe resp. distress + contraindication for NIV

6. postop

NAVA equation? Edi peak and min normals?

NAVA level x (edi peak - edi min) = PS above PEEP

Edi peaks 5-15
Edi min <4

What is the largest contribution to vent-induced lung injury

excessive VT causing lung overdistention

What is improvement in PaO2 directly related to? What is the safest way to increase it?

Directly related to an increase in mPaw, with PEEP being the safest way to increase it

What two values associate w/ impending fatigue

1. Increase in RR by 15-20%

2. reduction in VT

what do you place pt on FiO2 and PEEP wise for an SBT?

FiO2 0.50
<+8cmH2O
