Test 1 Flashcards
FiO2 greater than what and SATS still low, do what
60% - CPAP if ventilating adequ
When patient low on O2 , but ventilating adeq.
as well as Ph Normal, WOB not too high , SATS still low
apply more O2 up to 60%
When pt on FiO2 0.6 or more and still hypoxic
- Pt can ventilate adeq still
- Normal or high pH, PaCO normal or low
Mask CPAP
Pt not keeping up with ventilation, and can maintain airway and cooperate
BiPap (bilevel)
When to switch to CPAP from O2
Lower FiO2 of 0.6 or less, raise CPAP until PaO2/SpO2 adequate.
Goal= Use less O2 compensate with PEEP
(never go down on CPAP)
When to switch to BiPAP
Vent. failure assessed by pH and PaCO2
-Retaining CO2
pH is low and PaCO2 is high=
signs of early vent. failure
Bipap initial settings
IPAP 10-12cmH2O
EPAP 5cmH2O
FiO2 > or equal to pts current
When to intubate
Failing BiPAP, On higher IPAP , Low pH and PaCO2 still high, signs of fatigue, poor oxygenation, Apnea
Severe Resp Failure=
Low pH, lower than 7.25 and PaCO2 above 55
Comatose
out of it
obtunded
sort of out of it
combative
fighting it
Apneic? what to do
intubate and ventilate
Diaphoretic
cold and sweaty
pH < 7.25
intubate
Patient on Nonrebreather going to CPAP what oxygenation should be set at?
100%, Match NONREBREATHER
AA gradient when to intubate?
3-30
NIF worse than what to intubate
-20 cmH2O and FVC (minute ventilation) less than 10-15 ml/Kg
