Recently it has been found that men, who have more normal cervical fat than do women, have higher incidences of obstruction of the air ducts than do women. This is similar to what occurs with sleep apnea, but does not imply that male patients cannot be candidates for NAAP 11.
Recientemente, se ha encontrado que los hombres, al tener más grasa cervical, tienen mayor incidencia de obstrucción mecánica de la vía aérea que las mujeres, de forma similar a lo que ocurre con las apneas del sueño; sin embargo, esto no implica que los pacientes hombres no sean candidatos a ser sedados con NAAP 11.
