Perusing Perfusing
This is the process by which blood supplies oxygen and nutrients to all of the tissues within the body.
What is perfusion?
A reduction in this can be caused in either a reduction in Stroke Volume or Heart Rate
What is Cardiac Output?
This chronic disease, often called the "silent killer," is often managed by medications that relax the vasculature.
What is Hypertension?
What is Sodium?
This kind of blood flow increases afterload, and promotes intravascular clotting
What is turbulent flow?
An increase in this metric increases the workload of the heart, which reduces overall cardiac output.
What is Afterload?
This is the term for fluid accumulation in interstitial spaces due to increased vascular wall permeability.
What is Third Spacing; What is Edema?
What are Water and RBCs?
These two systems are the most sensitive in regards to receiving blood flow; not too much, and not too little, or there'll be problems!
What are the Renal and Cardiac Systems; What are the Kidneys and Heart?
This value can be shockingly low in athletes, who compensate by increased efficiency in stroke volumes, among other beneficial adaptations.
What is Heart Rate?
This is the term for how hard it is to push blood through the blood vessels.
What is Systemic Vascular Resistance
This graphical representation of the relationship helps to visualize how oxygen is transported around the body, as well as how various factors such as temperature and pH can affect the amount of oxygen transported.
What is the Oxygen-Hemoglobin Dissociation Curve?
Sepsis causes - among other things - intravascular hypovolemia by altering these two features of the vasculature.
What is Vascular Wall Permeability and Vascular Tone?
This property of the heart refers to the amount of force each pump can be given, independent of pre- and afterload.
What is Contractility?
An increase in this component of blood can result in fatty deposits forming along vessel walls, resulting in turbulent blood flow (increased SVR) or even total occlusion of the vessel in some cases.
Bonus: what class of medications do we recommend for patients with high amounts of this material in their blood?
What is Cholesterol?
Bonus: What are Statins?
Both carbon monoxide poisoning and anemia affect perfusion by reducing the availability of this molecule for oxygen to bind during transport.
What is Hemoglobin?
These are some of the major life changes a patient with hypertension might be asked to make.
What are the DASH diet, exercise, smoking cessation, limit EtOH/caffeine/decongestants, pharmacological interventions, at-home monitoring
In cardiac tamponade, perfusion is hindered due to this specific component of the pumping system?
What is preload/ventricular filling?
These receptors help to regulate vascular tone.
What are chemo- and baroreceptors?
Acidosis leads to the onset of poor perfusion by altering this feature of hemoglobin.
What is Oxygen Binding Affinity?
