PARAMETERS
Vt - 6-8ml/kg IBW
-Young, healthy, gonna have easier time choosing higher Vts
-Pulm hx, bad lungs, low CL, gonna need higher P's so might choose lower side of Vt
Pinsp - 10-15cmH20
-If don't want to excise wound, choose lower Pinsp
-If lungs healthy, they're healthy, gonna have easier time choosing higher Vt's
-If have decreased CL, gonna need higher P's to ventilate so use lower Pinsp
Remember, higher Vt = Higher pressures needed to ventilate pt
PS Lvl - 5-15cmh20
-5-10 = young, healthy, no pulm hx or issues, not long on vent
-10-15 = pulm hx, long vent times means muscle atrophy is v likely so they're not able to sustain their own efforts as easily
2. RR - Remember, if you choose a higher end Vt, you’re going to choose a lower RR bc we’re moving bigger volumes
-If you choose a lower end Vt, you’re gonna need a higher RR bc we’re moving smaller volumes. In addition, smaller Vts might be taken up by dead space so need to increase RR
4. PEEP = 5
5. FiO2 = Whatever they were on previously
-Ensure sats > 92% or PaO2 = > 65mmhg
-Want to go slightly higher than what they were on bc we know PPV increases DS
6. Ti = 1.0s
7. Tinsp Rise = Default
-Servo = 0.15s
-PB = 70%
6. Trigger = Flow trigger @ 2-3L/min
-Want it to be the most sensitive it can be w/o auto triggering
SET HIGH PRESSURE ALARM @ 30cmh20!
IF IN PRVC, MAKE SURE TO INCLUDE PRESSURE LIMIT INTO ACCOUNT
Servo & Evita = 5cmh20
PB = 3cmh20
Hamilton = 10cmh20
