Oxygen Training Seminar

October 27, 2009

This afternoon at 1, in LT1, there’s a seminar on oxygen therapy, and how to use the new oxygen guidelines.  It’s open to anyone who wants to turn up and hear about oxygen.

Oxygen Training Day

August 18, 2009

The next oxygen education training day is 28th August in Ninewells. The session begins at 1pm, with a lecture regarding the new oxygen guidelines from a local oxygen champion. Following this there will be workshops and lectures on oxygen humidification, and oxygen delivery devices.

If you are a junior doctor or a medical student, feel free to come along to the introductory lecture to get an overview of oxygen therapy in Tayside.

Why do COPD patients retain CO2 when given too much oxygen?

August 12, 2009

Most people think that this is due to loss of hypoxic drive, and subsequent hypoventilation.  Although this may be true for a small minority of patients, the majority will retain carbon dioxide due to V/Q mismatching.

Localised low PaO2 in the lung leads to localised vasoconstriction, to areas of poor ventilation have appropriately poor perfusion, redirecting blood to areas of better ventilation.  This protects the COPD patient from V/Q mismatch.

If a high concentration of oxygen is given to a patient, loco-regional low oxygen concentration will be abolished, and with local hypoxic vasoconstriction.  Thus, perfusion returns to normal, but ventilation is poor.  This is termed a shunt, and results in worsening hypoxia, and most importantly, hypercarbia.

New Downloads Page

August 5, 2009

I’ve added in a new page at the top there.  The “Useful Downloads” page has links to download the oxygen prescription sticker, the CTPA request sticker, the chest drain insertion care bundle, and the oxygen guideline.

I will put up more downloads once I have a minute or two.  If you have a request, please let me know and I’ll see what I can dig up.
