  • LUNA Microangiography - Hennepin Dive TV

    We’re back to discuss LUNA microangiography.

    Joining me today is Dr. Tom Masters and Ryan Wudtke, one of our stupendous hyperbaric techs.

    We will discuss what LUNA is, what it does, situations where this is currently utilized, set up, contraindications and some potential future uses.

    Below are a couple LUNA imaging examples as well.

  • Tech Talk - Hennepin Dive TV

    Hello again

    This time we’re doing something a little different and talking with two of our technicians (ie the ones who run the chamber).

    This is more of a discussion on what their jobs entail and some of the technical aspects to running a hyperbaric chamber.

  • Case 3 – CRAO - Hennepin Dive TV

    Case 3 – CRAO

    Hyperbaric oxygen has many uses not only related to diving related injuries.

    This case demonstrates a use that has nothing to do with the water: central retinal artery occlusion (CRAO).

    We have previously discussed this at EMDocs as well here.

    We discuss the following:

    • 2 cases
    • Anatomy and pathophysiology of this disease
    • Work up in the acute care setting
    • Other considerations
    • Need for hospitalization (these patients should probably get a stroke work up for their eye stroke)
    • Ophthalmology management
    • Stroke work up
    • Hyperbaric management
    • HCMC hyperbaric data

      • Case 1

      • Initial Vision: Hand motion
      • Final Vision: 20/200

        • Case 1

        Case 2

        • Initial vision: 20/400
        • Final vision:  20/25 -2
          • Case 2

        • Case 2 - AGE - Hennepin Dive TV

          For our second case we discuss another hyperbaric staple… arterial gas embolism.

          We cover the following:

          • A case
          • Quick pathophysiology overview
          • Acute management
          • Hyperbaric management

            • Below are our usual treatments used to treat AGE (courtesy of the USN Dive Manual Rev. 6).

          • Case 1 – The Bends - Hennepin Dive TV

            Case 1 – DCS

            Diving is what we love so why not start with a case of the bends or decompression sickness (DCS).

            This case covers a more severe case of DCS.

            Here’s a link to the Diver’s Alert Network (24/7 Emergency Contact 1-919-684-9111).

            We discuss the following:

            • Some useful resources if you are taking care of an injured diver.
            • General pathophysiology of DCS.
            • Risk factors associated with DCS.
            • General tips if you are taking care of a diver.
            • What we do to treat a DCS patient at a hyperbaric chamber.
            • General diving tips (for those who dive themselves).
            Usual treatment used to treat DCS (courtesy of the USN Dive Manual Rev. 6).
