The patient became severely. confused, agitated and combative approximately 12 hours after the first dose of. levofloxacin. The patientâs oxygen saturations were within normal limits, electrolytes. within normal limits, and no other cause for his change in mental status was apparent.
Stroke volume increases during exercise because the body's demand for more oxygen-filled blood increases, and an increase in stroke volume, due to contractions that are more powerful, will help eject...
Therefore, we can use the equation CO = HR x SV. This equation tells us that the cardiac output equals the heart rate (HR) , which is the number of heartbeats per minute, times the stroke volume (SV) , which is the volume of blood pumped by the ventricles with each heartbeat.If your body needs more blood, then your heart will increase the cardiac output.herefore, our equation looks like this: CO = HR x SV. We know that if you increase the amount of blood being pumped by your heart every minute, what you're really doing is increasing your cardiac output. And from our equation, we see that this means you either increased your heart rate or your stroke volume or both.
