Myocardial Oxygen Balance

Myocardial Oxygen Balance Maintaining the blood’s oxygen carrying capacity to vital organ structures and peripheral vascular beds is the primary consideration for cardiovascular perfusion. Oxygen content is defined as the number of cc’s contained in 100 cc of whole blood.  This value is derived from a combination of physical and physiological parameters that can be […]

The Essential Ingredient: ECMO Nurses

(Meet An Amazing Nurse ) I met Shannon 3 1/2 years ago when doing my first ECMO shift here in Texas.  I was pretty clueless about ECMO, as despite 17 years of experience, I was new to this hospital, and I had only worked in adult perfusion programs throughout my career. I had gotten a […]

Perfusion Notes: [6]

A Student Diary: To View all Diary Entries- Click Here Wet Labs & Simulations So over the last few weeks I have had a few things on my plate.  I had my first test and did just fine on that.  However, observations have dropped off a little.  I did have the opportunity to observe a […]

Tunnel Vision

Causes Extreme fear or distress, most often in the context of a panic attack. During periods of high adrenaline production, such as an intense physical fight. Altitude sickness, hypoxia in passenger aircraft Exposure to oxygen at a partial pressure above 1.5-2 atmospheres, producing central nervous system oxygen toxicity, notably while diving.  Other symptoms can include […]

If What You Did Yesterday Seems Big…

IF WHAT YOU DID YESTERDAY SEEMS BIG, YOU HAVEN’T DONE ANYTHING TODAY.  – Lou Holtz So this is a Perfusion Blog, and what does any of that have to do with us? Well to begin with we weren’t always us. Most of your old-school perfusionists had probably worked in another healthcare related field for quite […]

Methylene Blue & CPB

Is Methylene blue an Effective Adjunct Therapy for Treating Refractory Hypotension in Septic Endocarditis? This question was posed to me from a member of Perflist who submitted the question a few months ago. I really wasn’t familiar with the topic, have never seen Methylene Blue used for anything but urology cases to inspect the patency […]

From Point A to Point B : Packed Cells

Blood Transfusion on CPB I usually know if I am going to transfuse a patient during the course of cardiopulmonary bypass. Aside from the obvious co-factors associated with blood product administration (Kg, gender, HgB, age, susceptibility to stroke, estimated hemodilution, platelet count, antiplatelets Rx, and a few others), surgical dynamics also come into play. But […]

Metabolism and Hypothermia

Metabolism and Hypothermia Hypothermia while being a common problem associated with all operations, remains an inseparable aspect of cardiopulmonary bypass that has a profound impact on most enzyme systems, and the coagulation cascade. Activated clotting time, prothrombin times and partial thromboplastin times are prolonged and platelets become nonfunctional as the body temperature is lowered (usually […]

Mitral Stenosis

Mitral Stenosis The incidence of mitral valve stenosis is associated with scarring of the valve due to rheumatic fever.  Fibrosis restricts the mobility of the valve leaflets and commissures that eventually leads to valve funneling or retraction.  The normal mitral valve diameter is 4-6 cm2.  Hemodynamic changes occur when the valve aperture is diminished to […]

Aortic Insufficiency

Aortic Regurgitation :  101 Rheumatic fever, syphilis, arthritic diseases, or connective tissue disorders (Marfans syndrome), are the common causes for the development of aortic insufficiency (regurgitation). Aortic insufficiency results in greater than normal forward stroke volumes as a result of normal antegrade flow, combined with additional regurgitant filling due to valve incompetence.  This increase in […]

Give Me One More Kiss…

Give me one more Kiss & I will see you later … For most of my perfusion career and the rest of various first-assisting O.R. positions I have held, I was always about the patient. I don’t suggest that there were any lapses- since I was always very proactive in reassuring patients if I noticed […]

Locums Survey Results !

Perfusion Locums Survey  Results Authored By ;  Nadia Azuero, B.S., CCP, LP This Survey was Intended to Sort a Few Things Out… The bar is set pretty high when you arrive. I don’t know you, and you don’t know me. But as a perfusionist, I expect that you would scrutinize me as you would any […]

A Student Diary: To View all Diary Entries- Click Here Getting My Feet Wet: Well I am finally getting into the meat of my program.  I have already seen a rather diverse case load.  I would say the coolest thing I have seen so far is a heart transplant.  I had seen a lot of […]

Lungs & CPB

Lungs & CPB The most common pulmonary complication associated with cardiopulmonary bypass is postoperative atelectasis of the lungs. Preoperative conditions that predispose the patient to developing partial or total collapse of the lung are, surfactant depletion and mucus cell hyperplasia associated with chronic bronchitis developed from smoking, decreased FRC encountered with obesity, and cardiogenic pulmonary […]

A-V Blocks

Atrioventricular Blocks Classifications Incomplete–1st degree, 2nd degree Complete — 3rd degree First degree Characterized pr interval greater than 0.20 sec.  Junctional tissue delays impulse longer than normal. Second degree Every atrial impulse no conducted through to the ventricles — PR interval may be normal, shortened, or prolonged, but there are more P waves than QRS’s. […]
