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 and shape of the flow-volume loop, what do you suspect the patient having?

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

You are a respiratory therapist working the emergency room and go to shock room one to perform a ventilator-patient assessment on Mr. Smith, who is on PC AC mode.  You note that Mr. Smith looks a bit uncomfortable and see the following on the ventilator: rise time_.png What can be done to help Mr. Smith become more comfortable with the ventilator?

Your patient is currently on a ventilator with the following settings:VC AC f=16VT=450Flow=60 L/minFiO2=60%Peep=10PIP=35Plat=20I:E=1:3With the given information, calculate the patient’s Static Compliance

You are working as an ICU Respiratory Therapist and are performing a ventilator-patient assessment. Upon assessment you notice the following issue on the flow-time scalarautopeep_.pngBased on the waveform, which of the following best describes what is going on with your patient?

True or False: During PC AC or PC SIMV, the PIP will vary

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?

Which of the following are methods to avoid alveolar overdistention?I. Using Smaller Tidal VolumesII. Maintain a low plateau pressure (less than 30 cm H2O)III. Use of Volume Control modesIV. Use Pressure Limited VentilationV. Using High PEEP 

True or False: The flow-time scalar for inspiratory portion of a spontaneous breath resembles a sine wave flow pattern.
