Q

Flow waveforms

Square vs deselerating

A

Square: constant gas flow
Higher peak pressure
Shorter I time

Desal: slower gas flow
Improved gas distribution
Lower peak pressures

Q

Renal risks

A

> ITP = deceased co, decreased bp and decreased perfusion to kidneys

> renal venous pressure - < perfusion, altered neuro hormonal systems, < Raas, < renal blood flow, < gfr, fluid retention and olguria
