Final answer:
Conditions such as sleep apnea and obesity can interfere with supraglottic airway devices.
Step-by-step explanation:
Supraglottic airway devices may be interfered with by a variety of conditions. For example, in sleep apnea, the relaxation of tongue and throat muscles can cause them to push into the airway and obstruct it. Obesity is another risk factor for sleep apnea, as excess fat in the neck area can narrow the trachea. These conditions can hinder the proper functioning of supraglottic airway devices.
