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.

#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

  1. Thank you for this wonderful lecture and website! I was once given a wonderful mneumonic to remember intra and extra thoracic lesions that helps me on exams (and at the bedside) when I find myself working my way through it. I remember “in is out and out is in.” An intrathoracic lesion causes expiratory stridor and an extrathoracic lesions causes inspiratory stridor. Or another way, inspiratory stridor is secondary to extrathoracic lesions and expiratory stridor is secondary to intrathoracic lesions. Stridor can be substituted for obstruction but how I think about it as I am listening to the patient. Hope this is another way to get through the exam and the patient at the bedside.

    1. There is audio when I try it. Go to accrac.com and click the “play” button. Works for me for both episodes.

  2. Thank you for this! I know you like it to be podcast based so that we can listen to it while performing other tasks, but the handouts for the pulmonary really helped things come together. I sat and listened with the handouts, and then reinforced on my way to the hospital. I’m a very visual learner so thank you for that.

  3. In general, home sleep apnea tests are considered to be less accurate than type-I studies because of data loss from detached or malfunctioning monitoring equipment. 32 c Additionally, home monitors with fewer channels cannot discern between sleep and wakefulness, and therefore can only estimate an apnea-hypopnea index. Home sleep apnea tests can be an alternative to type-I studies in patients who are unable to present to a sleep laboratory. These tests are more accurate in identifying patients with a higher pretest probability of OSA and can rule out OSA in low-risk patients. 23, 32 34 Home sleep apnea tests are not recommended in patients with comorbidities such as congestive heart failure, chronic lung disease, or neurologic conditions because they have not been verified in these populations. 4, 6
