Episode 36: Pediatric respiratory anatomy and physiology with Dr. Schwengel

In this episode, episode 36, I welcome Dr. Deb Schwengel, one of our pediatric anesthesiologists and our residency program director, to the show to discuss the differences in anatomy and physiology in pediatric versus adult patients.

Episode 35: Pleural effusions with Dr. David Feller-Kopman

In this episode, number 35, I welcome Dr. David Feller-Kopman to the show.  Dr. Feller-Kopman is an associate professor of medicine and Otolaryngology and the director of Bronchoscopy and Interventional Pulmonology here at Johns Hopkins.  I interview him about pleural effusions including what they are, where they come from, how to categorize them, how to treat them and how to deal with them if they recur.

Episode 25: Advanced Ventilator Modes With Dr. Scott Stephens

In this episode I am joined once again by Dr. Scott Stephens as we review advanced ventilator modes, prone positioning, and ventilation of patients on VV ECMO.

Episode 23: Basic Ventilator Review with Dr. Scott Stephens

In this episode I welcome Dr. Scott Stephens, Pulmonary Critical Care Physician at Johns Hopkins to the show. Dr. Stephens and I discuss basic ventilator settings, how to appropriately ventilate patients with hypoxemic vs. hypercarbic respiratory failure and how to think about weaning patients off of the ventilator.

Episode 8: Management of Respiratory Diseases Part 2

This is the second and final episode dealing with the management of respiratory diseases.  In the first episode I covered the initial evaluation and preop preparation.  In this episode I cover intraoperative management, post-operative management, special issues related to one lung ventilation and special issues related to total pneumonectomy.

Episode 7: Management of the patient with respiratory disease part 1

This is the first of a two part series of episodes on the management of patients with respiratory disease.  In this, part 1, I cover the preoperative evaluation, history and physical exam, and the preoperative planning and optimization of the patient.  This includes the key board topics of smoking cessation and cardiac risk assessment.

Here are the slides that go along with this episode: Management of Respiratory Diseases slides part 1


Episode 5: Restrictive Lung Disease

In this episode I review restrictive lung disease.  This is meant to be a companion episode to Episode 4 which covered obstructive lung disease.  I cover the following topics:

-Definition and diagnosis of restrictive lung disease


-Extra-pulmonary causes (neurologic, musculoskeletal, pleural/mediastinal)

-Parenchymal causes

-Infant RDS


-Pulmonary Fibrosis

Episode 4: Obstructive Lung Disease

In this episode I mention the new ACCRAC mailing list which you can sign up for with the link right below the show description on the website accrac.libsyn.com.  You can also post comments on the website and email questions to accrac@accrac.com or accracpodcast@gmail.com.  I also highlight Rob MacSweeney’s fantastic critical care site called criticalcarereviews.com and his newsletter which you can subscribe to on his site.  The weekly newsletter includes the week’s top trials and papers in critical care.

The rest of the episode is a high yield board review of the ABA topic of obstructive lung disease.  I cover the following topics:

#Upper airway obstruction including extra thoracic and intra thoracic obstruction

#Flow volume loops and how to interpret them

#Lower airway and parenchymal obstruction including



#Cystic Fibrosis and bronchiectasis

#Mediastinal masses

Episode 3: Announcements and FIO2 in one lung ventilation

There are a few announcements I wanted to make including:

Check out pedsanesthesia.net.  Dr. Robert Greenberg, a pediatric anesthesiologist here at Johns Hopkins runs it and it has lots of great information and topics in pediatric anesthesiology.

If you have suggestions for a better website than this one please let me know!

If you know a good way to set up an email list serve for these kinds of announcements please let me know that as well.

And, finally, I address a surgeon’s comment to one of our residents that you should always use 100% fio2 when ventilating one lung during a thoracic case.  Listen to the podcast for details but the bottom line is you should NOT use 100% oxygen unless you have to in order to prevent hypoxia.
