If you have obstructive sleep apnea (OSA) and use a continuous positive airway pressure (CPAP) machine at home, it is a challenge to continue your CPAP therapy while traveling. Many patients who use CPAP machines might be tempted to leave their devices at home and go without it during their trip. However, there can be serious complications associated with sleep apnea, and it is not recommended to discontinue your therapy, even if it is only for a few days.
