This class has proctored assessments.

Your patient is currently on a ventilator with the following settings:VC AC f=16VT=450 Flow=60 L/minFiO2=40%Peep=5PIP=40Plat=20I:E=1:3With the given information, calculate the patient’s Airway Resistance

You are assisting in the PFT lab and are performing a spirometry test on a patient. After the patient performs the test, you notice their flow-volume loop looks like the image below. The solid black line shows the patient’s effort while the blue dash line shows a “normal” flow-volume loop.Based on the image of the flow-volume loop, what do you assume is going on with your patient?

You have an intubated patient with the following ventilator settingsVC/ACf=16VT=450Flow=60FiO2=40%PEEP=5Peak=20Plat=19Comp=30VTe=455Ve=7.28PETCO2=30On the current settings the ABG is as followspH=7.40PaCO2=40PaO2=90HCO3=24Based on this information, calculate the patient’s VD/VT Ratio. Remember to convert decimal to a percent.

Your patient is currently on a ventilator with the following settings:VC AC f=16VT=500Flow=60 L/minFiO2=60%Peep=10PIP=30Plat=20I:E=1:3With the given information, calculate the patient’s Static Compliance

True or False: Plateau Pressure can be obtained by pressing the expiratory hold button on the ventilator

During rounds, the ICU team comes to you and asks you for your patient’s peak and plateau pressures throughout the day.  Below is the data based on the time you saw the patient:0800PIP=20 cmH2OPlat=15 cmH2O1200PIP=25 cmH2OPlat=15 cmH2O1600PIP= 30 cmH2OPlat=15 cmH2OBased on the data, what can you conclude is going on with your patient?

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

Which phase of capnography represents continuing exhalation, with a significant increase in CO2. During this phase gas from both the conducting airways mixes with gas from the alveoli.

Your patient is currently on a ventilator with the following settings:VC AC f=20VT=500Flow=60 L/minFiO2=40%Peep=5PIP=30Plat=15I:E=1:3With the given information, calculate the patient’s Dynamic Compliance
