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

While looking at a capnograph waveform, the PETCO2 measurement can be assessed by looking at the very end of which phase? 

You are performing a ventilator assessment and decide to assess the patient’s pressure-volume loop and see the following: assisted ventilator breath flow-volume loop.png Based on the waveform graphic, what type of breath is being delivered to the patient?

True or False: When a Pressure-Volume Loop shifts to the left, this indicates an decrease in compliance
