Pulmonary Function Tests - PFT Interpretation Explained (Pulmonology)

Pulmonary function tests (PFTs) interpretation illustrated step by step by Dr. Roger Seheult. This video is a sample from the video series at MedCram.com: www.medcram.co...
This video includes discussion on restriction vs obstruction, FEV1, FVC, TLC (total lung capacity), DLCO, and extrinsic vs intrinsic causes of lung disease.
This pulmonary function test (PFT) interpretation video is part of the "MedCram Remastered" series: A video we've re-edited & sped up to make learning even more efficient.

Medical education topics explained clearly including: Respiratory lectures such as Asthma and COPD. Renal lectures on Acute Renal Failure, Urinalysis, and The Adrenal Gland. Internal medicine videos on Oxygen Hemoglobin Dissociation Curve / Oxyhemoglobin Curve and Medical Acid Base. A growing library on critical care topics such as Shock, Diabetic Ketoacidosis (DKA), aortic stenosis, and Mechanical Ventilation. Cardiology videos on Hypertension, ECG / EKG Interpretation, and heart failure. VQ Mismatch and Hyponatremia lectures have been popular among medical students and physicians. The Pulmonology and Pulmonary Function Tests (PFTs) videos and Ventilator-associated pneumonia lectures have been particularly popular with RTs. NPs and PAs have provided great feedback on Pneumonia Treatment and Liver Function Tests among many others. Mechanical ventilation for nursing and the emergency & critical care RN course is available at MedCram.com. Dr. Jacquet teaches our EFAST exam tutorial, lung sonography & bedside ultrasound courses. Many nursing students have found the Asthma and shock lectures very helpful. We're starting a new course series on clinical ultrasound & ultrasound medical imaging in addition to other radiology lectures.
Recommended Audience - Clinicians and medical students including physicians (MD and DO), nurse practitioners (NPs) , physician assistants (PAs), nurses (RNs), respiratory therapists (RTs), EMT and paramedics, and other clinicians. Review and test prep for USMLE, MCAT, PANCE, NCLEX, NAPLEX, NBDE, RN, RT, MD, DO, PA, NP school and board examinations.

This algorithm was very helpful for my mid-term exam in my family nurse practitioner program. I was able to memorize the diagram in my head which helped me to remember for the exam. I am a audio/visual learner, so diagrams are very helpful to me.

[@jacquelinefry3979]

Thank you so much. This made me understand better then anything I’ve watched

[@emersonsrandomvideos248]

Im an aspiring Respiratory Therapist. I hope i can pass the last leg of my course that includes PFT interpretation

[@diptanusaha5887]

Sir, how can we distinguish between asthma and emphysema from Lung Function Test

[@mdhen4]

I thought TLC couldn't be obtained with spirometry as the residual volume isn't measured. The residual volume has to be measured with some kind of body plethysmography or formal pulmonary function tests.

[@drgadham]

GREAT TEACHING

[@YeahJerrickT]

Amazing video! Thank you so much!

[@milliek2878]

Thanks! I got my test results back today and kinda bummed there wasn’t any sort of “on a scale of 1 to 10 here is how crappy your lungs are” statement. I’m curious about all the data

[@shainanembhard]

Thank you!

[@JM-ig4ed]

Thanks for all your videos -

[@jabbarshah7631]

So actually spirometer gives FVC FEV1 & TLC values then we need to compare FVC with Predicted FVC of that pt....to r/o if it's Restrictive or not & FEV1 vs FVC ratio to r/o if it's obstructive or not.. more over Obstructive is possible whether Fvc is over 80% of expected or lesser,depending on FEV1/Fvc ratio & TLC respectively....worthy noting that once Fvc is over 80% expected fcv Restriction pathaology is always absent.....

[@lotsofthisandthat9791]

How do you determine TLC I. The equation? Does the PFT computer provide this number? Thank you! Thumbs up on all your videos!

[@lavsmal9372]

Thank you. This really helped

[@viktoriousextensions394]

Awesome. Thank you so much!

[@Aesthetics.Torres]

Great video! Sharing this with friends!

[@Medcram]

Thank you for spreading the word!

[@fizzanaqvi3570]

Thank you thank you thank you sooooo much💜 you really helped me alot

[@JM-ig4ed]

Thanks for this explanation. I have pulmonary hypertension which contributes to my shortness of breath - 02 levels are always good. My PH was determined to be secondary to COPD. But, when I look at my numbers against what you are showing here - all my numbers are essentially normal. Now wondering why they are saying PH is secondary to COPD when my PFT numbers are virtually normal.

[@usmanyousoph7589]

Fev1/fvc ratio 70%

[@sujatarai6587]

Thank you for the videos 🇳🇵

[@Medcram]

Thank you!

[@lotsofthisandthat9791]

TLC>.80? How do determine TLC in the algorithm? Thank-you!

[@mcherrera1968]

SPIROMETRY

[@shahuzasaleem8422]

the background music is v annoying. hard to concentrate on the leclture

[@bandilestali4334]

[@dlopdx]

Mine was 94 then it went up to 105 after I got rid of Guinea pigs, is this good or bad

[@nighthawk5301]

I had pribably my 5tj pft today. I have asthma and for the first time ever it took 8 times and evevn then it wouldnt give clear results i guess. What does that even mean? I funished the time it takes for each breath but still she said it wasnt enough. Any idea what this mean?
