Question

A cardiac ultrasound patient is found to have a left ventricular stroke volume of 98 ml, and a resting heart rate of 65 bpm. What is this patient's cardiac output? 1. During a procedure, the patient's end diastolic volume was found to be 127 ml. The systolic volume was 45 ml. The patient's heart rate was 67. What is the patient's stroke volume? What is the patient's cardiac output? Are the stroke volumes or cardiac outputs normal? 2. The pressure difference through a patient's blood vessel is 80 mmHg. The resistance of the vessel is 266.67 mmHg min/L. What is the flow through this vessel? 3. A patient's blood viscosity is 3, the length of the vessel being measured is 15 mm, and the diameter of the vessel is 3.0 mm. What is the resistance of the vessel? 4.

Explanation / Answer

Ans-

Volume of blood is pumped out by the heart , is called cardiac output or minute output.

Cardiac output =stroke volume × number of beat

= 98 ml ×65 ml =6,370 ml
