COVID-19 Resources – Hemodynamics and ABGs using ROME
PDF DOWNLOADS FROM REVIEW
COVID-19 has left us with many unanswered questions about the care and treatment for our pandemic population.
In response to the rising questions and concerns, I have decided to create some educational videos that we can refer back to related to the care and treatment of our COVID-19 patients.
Let’s get started on understanding how hemodynamics and arterial blood gas results effect our COVID-19 population.
Basic Hemodynamics – Cardiac Output
For the body to function properly, the heart needs to pump blood at a sufficient rate to maintain an adequate and continuous supply of oxygen and other nutrients to the brain and other vital organs.
Cardiac output is the amount of blood your heart pumps each minute.
Cardiac output = stroke volume x heart rate
Basic Hemodynamics – Blood Pressure
Systemic Vascular Resistance = resistance to the flow of blood through the body’s blood vessels. It increases as vessels constrict (norepinephrine) and decreases when vessels dilate (sepsis).
