In the pressure-time scalar below, the difference between breath A and breath B would be caused by which of the following?  

Over the course of an 8-hour shift, the respiratory therapist notices that a patient receiving ventilation in the VC mode has had a decrease in the PIP from 35 to 30 cmH2O, and Pplat remained 25 cmH2O. What could have caused the change?

How would the ventilator values change if the RRT increased the inspiratory flow while set to deliver volume control (VC) breaths? Exp Time PIP Pplat Insp Time A No change Increases No change No change B Decreases Increases Increases Decreases C Decreases No change Increases Increases D Increases Increases No change Decreases

Use this information to answer the three questions below. A 58 kg (IBW) patient is being ventilated on a PB 980 ventilator with the following ventilator data:      Mode: PC-SIMV                                 FiO2:   0.50                              PS:  14 cmH2O      Mandatory Rate: 12 bpm                       Total Rate:  17 bpm      PEEP: 10 cmH2O                                 Mand Vt:  400 mL                    Spont Vt:  300 mL      Pinsp: 25 cmH2O                                  Ti:  1.2 sec 1.  What is the patient’s peak inspiratory pressure (PIP) given these settings? cmH2O 2.  What is the patient’s total minute ventilation? Lpm 3.  What ventilator setting would you change to decrease the minute ventilation?
