Pulmonary Diffusion Explained! Causes of Hypoxemia #2 of 5
HTML-код
- Опубликовано: 28 сен 2024
- Pulmonary diffusion is one of the 5 main causes of hypoxemia. Dr. Seheult provides a clear explaination and illustrations of pulmonary diffusion. See the other videos in this series: www.medcram.co...
This is video 2 of the 5 main causes of hypoxemia: diffusion problems. The other videos in this series on hypoxia are high altitude, hypoventilation, shunting, and ventilation perfusion mismatch (VQ mismatch).
This video is part of the "MedCram Remastered" series: A video we've re-edited & sped up to make learning even more efficient.

MedCram = More understanding in less time
Medical education topics explained clearly including: Respiratory lectures such as Asthma, Pulmonary Fibrosis, IPF, 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 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. Continuing Medical Education (CME), MOC Points, CEU / CEs for medical professionals.

Great video MedCram. I can measure this diffusion capacity for the lung in clinical practice in the respiratory lab. This is very helpful in diagnosing disease causing hypoxemia and breathlessness. I’ll demonstrate this in a video soon as it complements your physiological explanation
Very nicely explained. I liked this video. This is Anthony from Santacruz, Mumbai, India.
Thank you for watching!
Your are amazing thank for making things easier ♥️
Thank You.
How about the cut off of Aa gradient between VQ missmatch, shunt, and diffusion? We know that Aagradient will increase due to that disorder
It seems like there are two distinct (and conflicting) definitions of "shunt". In another video, you define a pulmonary shunt as a situation where blood is being diverted away from / around alveoli / lungs, i.e going from right heart to left heart without getting oxygenated. Here, shunting is defined as perfusion without ventilation, and deadspace is ventilation without perfusion. If anything, the first definition of "shunt" (diverted blood flow) sounds more like deadspace (ventilation without perfusion) than the second definition of "shunt" (perfusion without ventilation). Can you clarify? Thanks.
