FiO2 by 0.05-.10 increments
High PaO2 (O2 saturation)
- FiO2 in 0.05-.10 decrements
Acidosis/PACO2 increased
Secondary to ( =VT x RR. Normal range is 5–8L/min)
- VT by 1–2ml/kg IBW per hour (not higher than 10 ml/kg IBW)
- RR by 2–3 but do not exceed 35 breaths/min
- Peak pressure (on pressure support) to increase VT by 1–2 ml/kg IBW
Secondary to trauma, sepsis, burns, or high carbohydrates
- Correct underlying etiology
- Change diet to low carbohydrate, high fat
Alkalosis/PACO2 decreased
Secondary to
- RR by 2–3 breaths per minute
- VT by 1–2ml/kg IBW
- Peak pressure (on pressure support) by 5 cmH2O
Secondary to RR from anxiety, pain, CNS disorders
- sedation
- pain medication
