A mini CPAP machine, also known as a travel CPAP, is a portable version of a continuous positive airway pressure (CPAP) machine. These devices are designed to be smaller and more lightweight than traditional CPAP machines, making them easier to transport and use while traveling. Mini CPAP machines typically have similar features to full-size machines, such as adjustable air pressure settings and built-in humidifiers, but with a smaller and more compact design. They are used to treat sleep apnea, a sleep disorder in which a person's breathing is repeatedly interrupted during sleep.
