My wife's an RN. I had to ask her "Whats a nebulizer," and, follow up, "Is that something people carry with them to use in a car?"
I had imagined the 'inhalers' asthmatics employ to help them breathe.
She recalled that a Nebulizer was a machine unlikely to be employed while driving about in a rental car.? So I went online and found the instructions for use:
How to Use a Nebulizer:?
Prepare the medication: Follow the instructions provided by your healthcare provider to mix the medication with saline solution.
Assemble the nebulizer: Connect the medication cup, tubing, and mouthpiece or mask to the nebulizer unit.
Plug in the power source: If the nebulizer is electric, connect it to a power outlet.
Start the nebulizer: Turn on the device to create a mist.
Inhale the mist: Sit comfortably and breathe deeply through the mouthpiece or mask.
Continue until all medication is gone: The treatment typically takes 5-15 minutes.
Clean and store: Disassemble the nebulizer, clean it thoroughly, and store it according to the manufacturer's instructions.
