Question 82

Adaptaive Pressure Control with Ti Constant Assume Stabilization period after parameter change Decrease Ti

Answer 82

PIP: No Change-If pressure equilibration was not occurring initially then increasing Ti will allow more flow into the patient and result in increased VT and the vent will then step down the PIP to restore VT. Pplats would remain the same as same VT and same C Pplat: No Change MAP: Decrease RR: No Change Tidyn: No Change Tipause: Decrease Titotal: Decrease TE: Increase I:E: Decrease Vt: No Change MV: No Change

Question 83

Adaptaive Pressure Control with Ti Constant Assume Stabilization period after parameter change Increase Ti

Answer 83

PIP: No Change-If pressure equilibration was not occurring initially then increasing Ti will allow more flow into the patient and result in increased VT and the vent will then step down the PIP to restore VT. Pplats would remain the same as same VT and same C Pplat: No Change MAP: Increase RR: No Change Tidyn: No Change Tipause: Increase Titotal: Increase TE: Decrease I:E: Increase Vt: No Change MV: No Change
