By using the capnograph waveform below, what would you say the patient’s PETCO2 is?

You are a ICU Respiratory Therapist working in the Medical ICU. You were in the middle of your rounds when you Mr. Campbell’s ventilator alarming continuously. You turn towards the commotion and see that Mr. Campbell, who was intubated a minute ago, has self-extubated. Once you reach the bedside, you assess that the patient is exhibiting mild stridor symptoms and has an elevated respiratory rate. Which of the following would you do based on Mr. Smith’s condition?

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.
