In managing an emphysemic patient, what device may be utilized for treatment?

In managing an emphysemic patient, the use of CPAP (Continuous Positive Airway Pressure) is an appropriate choice because it helps in providing respiratory support to patients experiencing exacerbations of chronic obstructive pulmonary disease (COPD), which includes emphysema. CPAP delivers a continuous flow of pressurized air, which helps keep the airways open, reduces the workload on the respiratory muscles, and improves oxygenation. This can be particularly beneficial during acute respiratory distress episodes associated with emphysema, as it helps to prevent airway collapse and improve ventilation.

The other devices listed do not address the specific needs of an emphysemic patient in the same way. A defibrillator and an Automated External Defibrillator (AED) are primarily used for treating cardiac arrhythmias and do not provide the respiratory support necessary for managing emphysema. An inhaler with steroids can be part of a treatment plan for inflammation and can help during exacerbations, but it does not provide the same continuous airway pressure support that CPAP does, which is crucial in acute scenarios.
