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?

Strategies for increasing the mean airway pressure (MAP) include which of the following? Increasing the TCT Increasing PEEP Increasing Ti Increasing Vt

Given the following declaration, where is 62 stored in the scores array? scores = [83, 62, 77, 97]

You are treating a patient in the Medical ICU who had been intubated for 72 hours due to respiratory failure and pneumonia. The patient is being ventilated with the following settings: Mode: VC-SIMV                        Set rate: 8 bpm             Total rate: 16 bpm              Vt: 480 mL                                 PEEP: 10 cmH2O         FiO2: 40%                     Peak insp flow: 40 Lpm pH 7.41, PaCO2   43 mmHg, PaO2   117 mmHg, HCO3   22 mEq/L. Based on this information the most appropriate action to normalize the ABG is

If the respiratory therapist changes the flow pattern from constant to decelerating for a patient receiving volume control breaths, what will happen?

You are managing a patient and note that his minute ventilation has increased over the past 4 hours. You suspect that the patient’s CO2 production has increased. All of the following would increase metabolism and CO2 production EXCEPT?

The therapist is preparing to ventilate a 72 yo male with a history of congestive heart failure who was found unconscious in his apartment and subsequently intubated. The patient has an IBW of 74 Kg. Which of the following are the most appropriate initial ventilator settings for this patient?

After intubation and initiation of mechanical ventilation at the NBRC hospital, the physician asks you to provide an appropriate set rate and tidal volume for a male patient with a history of severe pulmonary fibrosis.  His IBW is 70 kg. You would recommend a set rate and tidal volume of
