Final answer:
The maximum AHI for untreated OSA varies depending on the severity of the condition. Mild OSA is defined by an AHI score of 5 to 14, moderate OSA by 15 to 29, and severe OSA by 30 or above.
Step-by-step explanation:
The maximum Apnea-Hypopnea Index (AHI) for untreated Obstructive Sleep Apnea (OSA) varies depending on the severity of the condition. AHI is a measure of the number of breathing disruptions per hour during sleep. The higher the AHI, the more severe the OSA.
In general, an AHI score of 5 to 14 indicates mild OSA, 15 to 29 indicates moderate OSA, and 30 or above indicates severe OSA. However, it's important to note that a healthcare professional, such as a sleep specialist, should assess and diagnose OSA, as they will take into account other factors such as symptoms and clinical evaluation.
For example, a patient with an AHI of 10 may have mild symptoms and not require treatment, while another patient with the same AHI may have severe symptoms and require immediate intervention.
