Nasopharyngeal Murphy eye
Nasopharyngeal airways need a Murphy eye too. Cut your own before insertion. The hole should be opposite and proximal to the manufactured lumen.
PS - Use a 15mm endotracheal connector to connect your nasopharyngeal airway to an anaesthetic machine. This can be really useful for ENT laryngoscopy as the surgeon has an airway-device-free-view! Need spontaneously breathing patient and propofol infusion.
