Equipment is ready to go before calling in the next person! 
I don’t have many extra or other items on the countertops and desks. This is so things don’t get contaminated with droplet and airborne particles. Also, with  limited items on surfaces, it makes the clinical setting more organized and less distracting for patients.
What are some of your practices?

Weekly Sims

Photos of the setup for Weekly FVC simulation, Weekly DLCO simulation and Weekly Biological DLCO.  Also, a screenshot of the QC log book.

Performing the weekly simulations in the PFT lab.  After completing the daily calibrations, FVC sim, DLCO sim and biological DLCO were done.

What do you think about our log sheet?

Weekly DLCO and Monthly Biological

Mouth piece on and mask off to do a weekly DLCO and monthly biological testing.  Quality control.

If you are curious about Hospital and Independent PFT simulations and #calibration, here is a CPSO document:

While on this topic, a quick shoutout to Bernie Ho and Tony Kajnar!

To have a better understanding of PFT maneuvers, watching the RT/technician screen as the patient performs these steps may be helpful for some students.
I have uploaded 4 videos (SVC, Spirometry, Body Plethysmography, and DLCO).

Keep in mind that these are for demonstration purposes only, and software models and standards can change.
