A Patient Is Receiving Mechanical Ventilation with a Fractional Inspired

question 25

Multiple Choice

A patient is receiving mechanical ventilation with a fractional inspired oxygen (FɪO₂) of 0.85 and a positive end-expiratory pressure (PEEP) of 5 cm H₂O.His arterial partial pressure of oxygen (PₐO₂) is 68 mm Hg,arterial oxygen saturation (SₐO₂) is 88%,and partial pressure of end-tidal carbon dioxide (PₑₜCO₂) is 32 mm Hg.Over the next few minutes his PEEP is titrated resulting in the following data:
$\begin{array} { | l | l | l | l | l | } \hline \text { Time } & \mathrm { F } _ { 1 } \mathrm { O } _ { \mathbf { 2 } } & \begin{array} { l } \mathrm { PEEP } ( \mathrm { cm } \\\left. \mathrm { H } _ { \mathbf { 2 } } \mathrm { O } \right) \end{array} & \mathrm { S } _ { \mathrm { P } } \mathrm { O } _ { \mathbf { 2 } } ( \% ) & \mathrm { P } _ { \mathbf { z t } } \mathrm { CO } _ { \mathbf { 2 } } ( \mathrm { mm } \mathrm { Hg } ) \\\hline 0600 & 0.85 & 5 & 88 & 30 \\\hline 0630 & 0.85 & 8 & 88 & 30 \\\hline 0650 & 0.85 & 10 & 90 & 32 \\\hline 0720 & 0.80 & 12 & 93 & 34 \\\hline 0740 & 0.80 & 15 & 90 & 25 \\\hline\end{array}$
At 0740 the single-breath carbon dioxide (SBCO₂) curve shifted to the right.What action should the respiratory therapist take at this time?

• A) Increase the FɪO₂ to 0.90.
• B) Reduce the set tidal volume.
• C) Continue to increase the PEEP.
• D) Reduce the PEEP to 12 cm H₂O.
