Use these ventilator waveforms to answer the three questions below.   What type of mandatory breaths are being delivered by the ventilator? What is the PEEP setting? What is the PS setting?

In MMV (minimum mandatory ventilation), the clinician sets a _______ target minute ventilation.

The purpose of the “test breath” in APC (adaptive pressure control) is to

Use this information to answer the four questions below: A 58 kg patient is receiving mechanical ventilation via the PB 980 in the ICU. Ventilator and ABG results are:         ABG:  pH 7.30/ PaCO2 50/ PaO2 220/ HCO3 23                        Mode: PC-AC                                    FiO2:   0.80                        Mandatory Rate: 16 bpm                 Total rate:  16 bpm                        PEEP: 12 cmH2O                               Ti:  0.9 sec                        Exhaled Vt:  400 mL                          Pinsp: 17 cmH2O What is the static compliance? Calculate the what the Vt will be if the Pinsp was decreased to 15 cmH2O. What settings change would be best to correct the PaCO2 to normal level? What settings change would you recommend to achieve a PaO2 in normal range?

Which of the following statements accurately describes the relationship between loops 1, 2, and 3, in the pressure-volume loops shown in the previous question?

The green line on the Drager waveform identified by the arrow represents    

Based on the following ventilator data, what mode and breath type is the patient receiving? The therapist has not adjusted the ventilator settings. 0800 1000 1200 Set Rate 6 6 6 Total Rate 10 12 10 Mech Vt 620 620 620 Spont Vt 410 300 370 PIP 26 32 30 Pplat 23 29 27  

What is the PIP for each mandatory breath in the previous question?

What is the significance of the portion of the P-V loop identified by the arrow?
