1 CEU credit*
• Total blood O2 content
• pH regulation
• Control of breathing
• Spirometry and flow volume loops
• SAO2 monitoring of blood (hemoglobin O2 saturation)
• Oxyhemoglobin saturation curve
• Causes of respiratory failure
• Brain blood flow
• CO2 narcosis-yes, CO2 is a narcotic gas.
• Causes of low O2
As an anesthesiologist we are forced into being pulmonary experts whether we want to be or not but having said that I still think pulmonary disease is one of the most difficult to understand for the average TCM student (and myself as well). That is why I am including a few basic concepts in pulmonary medicine in part one. By including some of these fundamentals I think you’ll agree that the entire two lectures are much easier to grasp. You’ll see that nearly all of the oxygen we use is in the form of oxyhemoglobin determined by the equation for total blood oxygen content. It’s absolutely essential that you understand how the body’s pH is regulated. Acutely it’s all through respiratory rate and CO2 levels. For those of you who have not had the misfortune of ending up in an operating room (as a patient) or in the ER, I’ll explain how a pulse oximeter works. Through the use of a tiny little finger probe, oximetry has revolutionized anesthesia and emergency medicine.
I’ll discuss the oxyhemoglobin saturation curve which plots oxygen tension verses % hemoglobin saturation to reveal a very interesting curve. From there we cover hypoxemia and respiratory failure and the red flag signs and symptoms to look for. Hyperventilation syndrome or panic attack can be a frightening event for both the patient and the acupuncturist. I’ll go over all that is needed to understand this interesting red flag and how to successfully stop an attack. Lastly we cover what is perhaps one of the most curious things about CO2, is that it acts like an anesthetic gas in high enough blood concentrations. We will cover how and why this could occur and what to look for. We end on the most common mechanisms that can lead to hypoxemia and high (retained) CO2 both of which are features of respiratory failure. CO2 also determines brain blood flow.
This is an hour well spent for those who wish to know more on the basics of pulmonary medicine and the underlying mechanisms of the red flags that develop. I would recommend that this part be watched first in the order we have it arranged, so that you have these basic concepts down before moving on to more common pulmonary red flags in section two.
