The nurse's role in this situation is to provide clear and compassionate guidance regarding the complex decision about continuing or discontinuing ventilator support. Referring to the hospital's policies provides a structured approach to making such decisions and ensures that the decision aligns with ethical and legal standards. This approach also supports the spouse by providing concrete information and a framework within which to make an informed decision.

The goal of PEEP therapy in acute lung injury (ALI) is to reduce physiologic shunting, which is the perfusion of blood through unventilated or collapsed alveoli. This results in hypoxemia and impaired gas exchange. PEEP therapy increases the end-expiratory pressure and prevents alveolar collapse, thus improving ventilation and oxygenation. PEEP therapy does not necessarily decrease PAP (pulmonary artery pressure), decrease airway resistance, or increase cardiac output. In fact, PEEP therapy may have adverse effects on these parameters, such as increasing intrathoracic pressure, reducing venous return, and decreasing cardiac output.

Ventilator-associated events (VAEs) can be prevented by reducing the risk of aspiration and maintaining airway hygiene. Subglottic suctioning is an effective measure to remove secretions that accumulate above the endotracheal tube cuff, which can harbor bacteria and lead to infection. This intervention helps prevent the development of pneumonia and other VAEs. References: AACN Adult CCRN Certification Review Course, AACN CCRN Exam Handbook.
