Question

"Which goal is most important when positive end expiratory pressure (PEEP) is being used for a patient with acute respiratory distress syndrome (ARDS)?

1.Correcting hypoxemia
2.Improving lung sounds
3.Lowering the work of breathing
4.Stabilizing hemodynamic parameters"

Answer 1

The primary goal of using PEEP in ARDS patients is to correct hypoxemia by increasing lung volume and improving gas exchange, with decreasing the work of breathing as a secondary benefit.

Step-by-step explanation:

The most important goal when using positive end expiratory pressure (PEEP) for a patient with acute respiratory distress syndrome (ARDS) is correcting hypoxemia. PEEP helps to increase the lung volume and keep the alveoli open at the end of expiration, thereby improving oxygenation by increasing the surface area available for gas exchange. While PEEP can also help to decrease the work of breathing, this is typically a secondary benefit compared to the primary goal of addressing hypoxemia in the context of ARDS. It's also important to note that PEEP can affect hemodynamic parameters by increasing intrathoracic pressure; however, this is managed carefully to ensure oxygenation remains the priority treatment goal.
