Lesson Transcript

Instructor: Rebecca Gillaspy
Dr. Gillaspy has taught health science at University of Phoenix and Ashford University and has a degree from Palmer College of Chiropractic.

The amount of blood being pumped through your body changes constantly due to the demands of daily life. In this lesson, you will learn how your body adjusts the heart rate and stroke volume to increase or decrease blood flow.

Cardiac Output

The volume of blood your heart pumps per minute, known as your cardiac output, varies with the demands you put on your body. We previously learned that the cardiac output (CO) is calculated by multiplying the number of heartbeats per minute (which is your heart rate, or HR) times the volume of blood pumped out of the heart with each heartbeat (which is your stroke volume, or SV). So:
cardiac output (CO) = heart rate (HR) x stroke volume (SV)
The cardiac output of your heart is a constantly changing amount that adjusts to any physical or emotional demands you put on your body. In this lesson, we will look at some of the factors that influence your heart rate and stroke volume.

lyudmila [28]

SBP is a serious complication in patients with cirrhosis with high mortality rates (20–40%).

Patients at risk of developing SBP can be categorized in three groups firstly patients with active variceal bleeding patients with ascitic fluid protein <10 g/dl secondly those with a prior episode of SBP.

The most common bacteria causing SBP are gram-negative Escherichia coli and Klebsiella pneumoniae and gram-positive Streptococcus pneumoniae usually only a single organism is involved. Spontaneous bacterial peritonitis (SBP), an infection of ascitic fluid without a definitive intra-abdominal source that can be surgically treated is a common complication in patients with cirrhosis and ascites. Spontaneous bacterial peritonitis (SBP),is treated with a 10 to 14 day course of antibiotics .
