- The Brain Is Still In Charge ()
The Autonomic Nervous System The autonomic nervous system controls specific body processes, such as blood circulation, digestion, breathing, urination, heartbeat, etc. The autonomic nervous system is named so because it works autonomously, i.e., without a person’s conscious effort. The primary function of the autonomic nervous system is homeostasis. Apart from maintaining the body’s internal environment, it […]
- Angina vs Acute Coronary Syndrome ()
Angina Angina is chest pain or discomfort you feel when there is not enough blood flow to your heart muscle. Your heart muscle needs the oxygen that the blood carries. Angina may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, […]
- Right Heart Failure ()
When addressing heart failure, most commonly, the left ventricle (LV) is the topic of discussion, and the right heart overlooked. However, the right ventricle (RV) is unique in structure and function and is affected by a set of disease processes that rival that of the LV. This article will review the normal structure and function of the RV, […]
- The 4 Chambered 2 Stage Pump ()
Your heart is at the center of your circulatory system. This system is a network of blood vessels, such as arteries, veins, and capillaries, that carries blood to and from all areas of your body. Your blood carries the oxygen and nutrients that your organs need to work properly. Blood also carries carbon dioxide to […]
- Management of Cardiovascular Emergencies ()
Truth Be Told, The Dispatcher, EMS, and the ER Couldn’t Find A Heart Attack In A Basket Of Puppies Most cases of Acute Coronary Syndrome are dispatched to EMS as a chest pain call. Ambulance services will send an Advanced Life Support ambulance to the scene. The Advanced Life Support Ambulance has the capability of […]
- Acute Coronary Syndrome ()
Acute coronary syndrome (ACS) refers to a group of conditions that include ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), and unstable angina. It is a type of coronary heart disease (CHD), which is responsible for one-third of total deaths in people older than 35. Some forms of coronary heart disease can be asymptomatic, […]
- Cardiogenic Shock ()
Cardiogenic shock, also known as cardiac shock, happens when the heart cannot pump enough blood and oxygen to the brain and other vital organs. This is a life-threatening emergency. Without oxygen-rich blood reaching the brain and other vital organs, blood pressure drops, and the pulse slows. Most often the cause of cardiogenic shock is a serious […]
- Perfusion – It’s All About The Flow ()
Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, usually referring to the delivery of blood to a capillary bed in tissue. Perfusion is measured as the rate at which blood is delivered to tissue, or volume of blood per unit time (blood flow) per unit tissue mass. The word is derived from the French verb “perfuser” meaning to “pour […]
- Getting Blood To The Body ()
How the Heart Works The heart is an organ, about the size of a fist. It is made of muscle and pumps blood through the body. Blood is carried through the body in blood vessels, or tubes, called arteries and veins. The process of moving blood through the body is called circulation. Together, the heart and vessels make up […]
- The Mammalian Dive Reflex ()
The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date. It optimizes respiration by preferentially distributing oxygen stores to the heart and brain, enabling submersion for an extended […]
