Hemodynamic Monitoring and Rule of Nines Review

Practice vocabulary flashcards covering hemodynamic monitoring via Swan Ganz catheter and burn assessment using the Rule of Nines.

Cardiac Output (CO) Formula

The calculation defined as $CO = HR \times SV$ (Heart Rate multiplied by Stroke Volume).

RA (Right Atrium) / CVP (Central Venous Pressure)

Measurements that represent RV (Right Ventricular) Preload.

PVR (Pulmonary Vascular Resistance)

Measurement representing RV (Right Ventricular) Afterload.

PAOP (Pulmonary Artery Occlusion Pressure)

Preferred term for LVEDP (Left Ventricular End Diastolic Pressure), also known as PCWP (Pulmonary Capillary Wedge Pressure).

PAd (Pulmonary Artery Diastolic Pressure)

A measurement used as a Preload Surrogate.

SVR (Systemic Vascular Resistance)

Measurement representing Afterload for the Left Ventricle, also associated with blood pressure from an Arterial line or cuff.

Phlebostatic Axis

The anatomical reference point where all transducers must be kept.

Pressure Bag Setup

Utilizes $500,mL$ of NS (Normal Saline) and is maintained at a pressure of $-300,mmHg$.

PA Distal Port

Monitors Pulmonary Artery pressures and is used to draw SvO2; do NOT use for meds, though intermittent meds are OK at a rate of $1,mL$ over $1,min$.

VIP/AUXILLARY Port

The port on the Swan Ganz catheter used specifically for medications (CVC).

RA PROXIMAL (CVP) Port

Port used for monitoring CVP and is considered OK for medications in a pinch.

Thermistor

A component that measures the temperature of injectate ($\Delta$ of injectate temp) for Cardiac Output (CO) calculations.

Balloon Line

The component used for wedging (PAOP); the syringe must be kept deflated when not in use.

Rule of Nines: Head and Neck

Total surface area accounting for $9\%$ ($4.5\%$ front and $4.5\%$ back).

Rule of Nines: Arms

Each arm accounts for $9\%$ total ($4.5\%$ front and $4.5\%$ back).

Rule of Nines: Legs

Each leg accounts for $18\%$ total ($9\%$ front and $9\%$ back).

Rule of Nines: Torso / Trunk

The front (chest and abdomen) accounts for $18\%$ and the back accounts for $18\%$ ($9\%$ upper and $9\%$ lower).

Rule of Nines: Perineum

The anatomical area accounting for $1\%$ of the total body surface area.
