Ans) a.References the cardiac output to body size
Explaination:
- Cardiac index (CI) is a haemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), thus relating heart performance to the size of the individual. The unit of measurement is litres per minute per square metre (L/min/m2).

Case 1 – New data set: ABP = 90/60 mm Hg, HR 145 Beats/min, cardiac output = 3 l/min, CVP = 0 mm Hg, PAP = 30/10 mm Hg, PCWP = 2 mm Hg. Calculate the SV and fill in the table below and answer the question below. Mean arterial pressure (MAP) mmHg Systemic vascular resistance (SVR) dynes Mean pulmonary artery pressure (PA mean) mmHg Pulmonary vascular resistance (PVR) dynes Stroke volume (SV) ml Regarding Case 1.

Cardiac parameters: -what is cardiac parameters? -explain each: preload, after load, cardiac output and index, etc -what are the physiology related to IABP? Including indications, nursing care, weaning -and what are treatment and relationship to IABP?
Case 1- New data set: ABP: 90/60 mm Hg, HR 145 beats/min, cardiac output=3 l/min, CVP=0 mm Hg, PAP=30/10 mm Hg, PCWP=2 mm Hg. I calculated that MAP=70 mm Hg, SVR=1866.7 dynes, PA mea=16.7 mm HG, PVR=139.2 dynes, and SV=20.1 ml. I just need help with the conceptual questions: A. How would SV normally respond if venous return increases? (increase, decrease, or nothing) B. What would be the best treatment for the patient? (diuretics, aortic balloon pump, intravenous fluid admin,...

Physiology question about cardiac output
There are several ways how to measure cardiac output in the clinical setting. Research and describe three methods and discuss potential drawbacks of each. Finally, propose a new method to measure cardiac output (e.g. via imaging method, invasive tracing, using physiologic markers)

Data set: ABP=90/60 mm Hg, HR 110 beats/min, cardiac output = 3 L/min, CVP = 15 mm Hg, PAP = 50/35 mm Hg, PCWP = 6 mm Hg, EF = 60%. Please show all work to justify answer 1. Calculate the PVR
What defect in cardiac energy metabolism would appear to be the basis of the high-output cardiac failure observed?
Given the information below please choose the correct answer with an explanation of why you chosed that answer. Case 2 – New data set: ABP = 90/60 mm Hg, HR 145 Beats/min, cardiac output = 3 l/min, CVP = 12 mm Hg, PAP = 45/30 mm Hg, PCWP = 18 mm Hg, Ejection Fraction = 20%.
