Front

What does an arterial blood gas help assess?

Back

An arterial blood gas helps assess acid–base status, ventilation, and oxygenation.

Front

What is the typical adult arterial blood pH range?

Back

The typical adult pH reference range is $7.35$ – $7.45$ .

Front

What does $\mathrm{PaO_2}$ measure, and what is its typical range?

Back

$\mathrm{PaO_2}$ measures oxygen dissolved in arterial blood; the typical adult value is about $80$ – $100\ \mathrm{mm\ Hg}$ .

Front

What is the first step in a systematic ABG interpretation?

Back

Check the pH first to determine whether the blood shows acidemia, alkalemia, or a pH within the reference range.

Front

Does a pH within range rule out an acid–base disturbance?

Back

No. A pH within the reference range does not, by itself, rule out an acid–base disturbance.

Front

What pattern fits acidemia with high $\mathrm{PaCO_2}$ ?

Back

With acidemia, a high $\mathrm{PaCO_2}$ fits a respiratory-acidosis pattern.

Front

What does $\mathrm{PaCO_2}$ reflect, and what is its typical range?

Back

$\mathrm{PaCO_2}$ reflects the respiratory component; its typical adult range is $35$ – $45\ \mathrm{mm\ Hg}$ .

Front

What does $\mathrm{HCO_3^-}$ reflect, and what is its typical range?

Back

$\mathrm{HCO_3^-}$ reflects the metabolic component; its typical adult range is $22$ – $26\ \mathrm{mEq/L}$ .

Front

What does $\mathrm{SaO_2}$ measure?

Back

$\mathrm{SaO_2}$ is the percentage of hemoglobin saturated with oxygen; the typical adult value is about $95$ – $100\%$ .

Front

What pH indicates acidemia?

Back

Acidemia is indicated by an arterial pH below $7.35$ .

Front

What pH indicates alkalemia?

Back

Alkalemia is indicated by an arterial pH above $7.45$ .

Front

What pattern fits acidemia with low $\mathrm{HCO_3^-}$ ?

Back

With acidemia, a low $\mathrm{HCO_3^-}$ fits a metabolic-acidosis pattern.
