Which device is recommended instead of small volume nebulizers in high infection control areas?

Handheld nebulizers
Aerosol generators
Metered dose inhalers (MDIs)
Continuous positive airway pressure (CPAP) devices

The correct answer is: Metered dose inhalers (MDIs)

Metered dose inhalers (MDIs) are recommended instead of small volume nebulizers in high infection control areas primarily due to their ability to deliver medication effectively with a significantly lower risk of aerosolizing pathogens. MDIs utilize a propellant to send a measured dose of medication directly to the lungs, reducing the generation of nebulized particles that can spread infections. In high infection control areas, such as intensive care units or during respiratory outbreaks, minimizing the risk of airborne transmission is crucial. MDIs can be used with a spacer to enhance medication delivery while containing the aerosol within the device, further limiting the potential for contamination. Other devices such as handheld nebulizers or aerosol generators may still aerosolize particles, increasing the risk of infection transmission. Continuous positive airway pressure (CPAP) devices are designed for different therapeutic purposes, primarily to assist breathing in patients with obstructive sleep apnea, and are not primarily used for medication delivery in the context of this question.
