A 58 kg patient is receiving mechanical ventilation via the PB 980 in the ICU. Ventilator and ABG results are: ABG:  pH 7.28/ PaCO2 56/ PaO2 76/ HCO3 25Mode: PC-AC                                       FiO2:    1.0 Mandatory Rate: 14 bpm                    Total rate:  14 bpm PEEP: 10 cmH2O                                   Ti:  1.1 sec with a “no flow” zone on insp. Exhaled Vt:  410 mL                               Pinsp: 13 cmH2O                              Which of the following changes choices would improve ventilation of this patient? Increase the mandatory rate to 16 Change the mode to SIMV Increase Pinsp to 15 cmH2O Increase the Ti to 1.8 sec

A 62 kg patient has been mechanically ventilated for 8 hours after being admitted via the ER for respiratory failure secondary to pneumonia. He is on the following settings:Mode: VC-SIMV                     PEEP: 5 cmH2O                    Peak Flow:  40 Lpm          FiO2:   50                 Total Rate:  14 bpm                   Set Rate: 8 bpm          PIP:  24 cmH2O                     Pplat: 17 cmH2O Mandatory Vt:  440 mL                Spont Vt: 250 mL                               Which of the following changes will increase minute ventilation for this patient?  

A patient in the cardiac ICU has developed hypervolemia and pulmonary edema. This diagnosis would show which of the following changes in pulmonary mechanics?

While on mechanical ventilation (PC and/or VC), acceptable strategies to improve oxygenation include which of the following? Increasing inspiratory time Increasing FiO2 Increasing mean airway pressure Adding PEEP

The RRT is preparing a PB840 ventilator for admission of a 70 kg patient to the ICU following surgery. The physician has written an order for PC-SIMV. Which of the following parameters will the respiratory therapist directly set on the ventilator? Inspiratory flow Mandatory rate Inspiratory pressure Inspiratory time

Given the following ventilator settings, what FiO2 is needed to achieve a PaO2 of 80 torr?Mode:  VC-SIMV            Set rate: 12 bpm           Total rate: 16 bpm        Vt: 400 mLPEEP: 7 cmH2O             FiO2: 40%                     pH 7.41, PaCO2 43 mmHg, PaO2 60 mmHg, HCO3 22 mEq/L

You are managing a patient with severe pneumonia who was intubated and placed on positive pressure mechanical ventilation two hours ago. The goals of mechanical ventilatory support for this patient include: Stabilizing the chest wall Maintaining acceptable lung volumes Ensuring adequate tissue oxygenation Reducing the level of WBCs in the sputum Reduction in the work of breathing (WOB)

An unconscious patient (83 Kg IBW) with closed head trauma has been intubated in the ER and is receiving mechanical ventilation secondary to inability to protect his airway (no gag reflex). Mode: VC-AC               Set rate 14 bpm            Total rate 20 bpm         Vt 580 mLPEEP: 5 cmH2O             FiO2: 40%pH 7.50, PaCO2 30 mmHg, PaO2 98 mmHg, HCO3 22 mEq/L, BE 0Based on this information the most appropriate action to increase the PaCO2 would be to

The RT is preparing to convert a patient from volume control to pressure control ventilation on a PB 840 ventilator. While in VC, the RT obtains the following values:Vt 650 mL        Flow 50 Lpm      PIP: 34 cmH2O     Pplat: 29 cmH2O       PEEP: 12 cmH2O What is the appropriate Pinsp (delta P) for this patient in PC?
