You have a patient who is on PC AC mode with the following settings. The patient has an IBW of 60 kg.  Vent Data:PC/ ACf=18 Inspiratory Pressure= 12Ti= 0.8 secondsFiO2=60%Peep=8Flow Trigger= 2 Patient DataPatient Rate=24Vte= 220 mlsVe=5.28 L/minI:E=1:4Peak=24Plateau=20Compliance=40The physician requested you draw an ABG to see how well the patient is doing with the current settings. The results are as followspH=7.27PaCO2=50PaO2= 100HCO3= 34SaO2=99%From the information provided, what ventilator changes, if any, would you make to correct the patient’s ABG?

A patient is brought to the surgical unit after a TURP. He has a three- way Foley catheter. The nurse notices very dark red output in the catheter. What is the appropriate nursing intervention that the nurse should perform first?

This type of trigger is associated with assisted breaths and/or spontaneous breaths. With this trigger, the ventilator delivers a breath when it detects a pressure drop at the proximal airway due to the inspiratory effort of the patient and the ventilator begins the inspiratory phase. Which trigger am I referring to?

You have a patient on VC/AC mode with the below settingsf=24VT=500Flow=60FiO2=40%Peep=5Flow Trigger=2An ABG was drawn while the patient was on their current settings showing the following results:pH=7.52PaCO2=25PaO2=90HCO3=24Assuming that the patient is NOT over-breathing and that the VT is set appropriately based on their IBW, what ventilator changes would you make if any?

You have a patient on HFOV with the following parametersDelta P=70 cmH2OHz=12 HzmPaw=32 cmH2OI-Time=33%Bias Flow=40 L/minAn ABG was drawn and the following were the resultspH=7.20PaCO2=60PaO2=60HCO3=22Based on the ABG results, what change if any should you make to improve the results?

You have a male patient who is 150 lb with the following ventilator settingsVC ACf=14VT=500 mlsFlow=60 L/minFiO2=40%PEEP=5Calculate the patient’s Alveolar Ventilation.

While on PSV mode, which parameter controls when the ventilator cycles to expiration?

True or False: The mode APVcmv utilizes inverse I:E ratio ventilation to help recruit alveoli in severely hypoxemic respiratory failure patients.

You are a respiratory therapist working in the ICU. While performing a ventilator-patient assessment, you notice that the patient’s Capnograph as seen below Shark Fin Capnography.jpg Based on how the capnograph waveform looks, which of the following best represents what is going on with your patient?
