- 10 above PIP.
- occaionally used to INDUCE resp alkalosis, which reduces intracranial pressure...in pts with closed head injurys.
- Vt delivery varies with lung characteristic...LESS control over PaCO2..
- Vent does ALL the work, Set Rate(f), and Vt...able to control PaCO2..Pt is sedated.
5 True/False Questions
SIMV Advantages → Enhanced pt-vent synchrony, pt assumes some WOB, can be used to wean, set rate and slowy decrease rate...REDUCES HYPERVENTILATION seen with resp alkalosis..
Spontaneous breaths → vent controls timing or Vt, or both.
Non-Invasive → artificial airway..Endo tube, Trach.
Disadvantage of VCV → Vt delivery varies with lung characteristic...LESS control over PaCO2..
Invasive → artificial airway..Endo tube, Trach.
