A Patient Receiving Mechanical Ventilation Has an Exhaled Tidal Volume

Multiple Choice

A patient receiving mechanical ventilation has an exhaled tidal volume (Vᴛ) of 500 mL and a positive end expiratory pressure setting (PEEP) of 5 cm H₂O.Patient-ventilator system checks reveal the following data:
$$\begin{array} { | l | l | l | l} \hline \text { Time } & \text { PIP } \left( \mathrm { cm } \mathrm { H } _ { 2 } \mathbf { 0 } \right) & \mathrm { P } _ { \text {platen } } \left( \mathrm { cm } \mathrm { H } _ { \mathbf { 2 } } \mathbf { O } \right) \\\hline 0600 & 27 & 15 \\\hline 0800 & 29 & 15 \\\hline 1000 & 36 & 13 \\\hline\end{array}$$

1) Tracheobronchial suctioning
2) Increase in the set tidal volume
3) Beta adrenergic bronchodilator therapy
4) Increase positive end expiratory pressure

A) 1 and 3 only
