Hemodynamic and Respiratory Values

Flashcards covering key hemodynamic and respiratory values essential for understanding patient status.

CVP

Central Venous Pressure; normal range is 2 – 6 mmHg.

PAP

Pulmonary Artery Pressure; normal range is 15 – 25 / 8 – 15 mmHg.

PCWP

Wedge Pressure; normal range is 4 – 12 mmHg.

Cardiac Output

Amount of blood the heart pumps; normal range is 4 – 8 L/min.

SVR

Systemic Vascular Resistance; normal range is 800 – 1600 dynes/sec/cm⁵.

pH

Normal range for Arterial Blood Gas is 7.35 – 7.45.

PaCO₂

Partial pressure of carbon dioxide; normal range is 35 – 45 mmHg.

PaO₂

Partial pressure of oxygen; normal range is 80 – 100 mmHg.

HCO₃

Bicarbonate level; normal range is 22 – 26 mEq/L.

SaO₂

Oxygen saturation; normal range is 95 – 100%.

Base Excess

Normal range is ±2.

Tidal Volume (Vt)

Initial setting for ventilation; normal range is 6–8 mL/kg IBW.

RR (Respiratory Rate)

Initial setting for adults; normal range is 12–20 bpm.

PEEP

Positive End-Expiratory Pressure; normal setting is 5 cmH₂O.

FiO₂

Fraction of Inspired Oxygen; normal setting is 40–60%.

SpO₂ Goal

Target oxygen saturation for most patients; goal is ≥ 92%.

P/F Ratio

PaO₂/FiO₂; normal is > 300.

MIP (NIF)

Maximum Inspiratory Pressure; normal range is –80 to –100 cmH₂O.

RSBI

Rapid Shallow Breathing Index; good for weaning if < 105.

A-a Gradient

Alveolar-arterial gradient; normal is < 25 mmHg.

VD/VT Ratio

Normal range is 0.2 – 0.4.

C(a–v)O₂

Difference in oxygen content; normal range is 4 – 6 vol%.

Static Compliance (Cstat)

Normal range is 60 – 100 mL/cmH₂O.

Dynamic Compliance (Cdyn)

Normal range is 30 – 40 mL/cmH₂O.
