Calculate Systemic Vascular Resistance in HF
A 75-year-old female patient presents to the emergency department with acute shortness of breath and exhibits elevated jugular venous distension. The nurse notes a blood pressure of 88/60 mmHg and a heart rate of 110 bpm. The patient has a history of congestive heart failure and is currently on a regimen of diuretics and ACE inhibitors. Based on the patient's signs and symptoms, calculate the systemic vascular resistance (SVR) using the following formula:
SVR = (MAP - CVP) / CO
Where MAP is the mean arterial pressure, CVP is the central venous pressure, and CO is the cardiac output. Assume the CO for this patient is 4.0 L/min, and for severe heart failure, CVP is often around 10 mmHg, with a MAP typically calculated as:
MAP = (Systolic BP + 2 x Diastolic BP) / 3
Using the patient's blood pressure measurements, fill in the blank with the calculated value of SVR in dynes·sec/cm5;
SVR = __________.
