The average cost to install a bathtub is $2,838, but can range from $1,000 to $4,500, depending on the type of tub and modifications needed. The average cost of the tub itself ranges from $200 to $2,000 or more.
If you have a sleep study such as a polysomnogram or even home sleep testing, you may receive a report from your doctor that describes the severity of your sleep apnea according to the apnea-hypopnea index (AHI), but what is the AHI? Learn what the AHI is and how the measure is used to assess the severity of sleep apnea and your response to therapy. AHI, or the apnea-hypopnea index, is a numerical measure that accounts for the number of pauses in your breathing per hour of sleep. 1  These breathing disturbances are typically associated with either a brief arousal or awakening from sleep or a 3 to 4 percent drop in the blood oxygen levels, called a desaturation.
Each episode must last at least 10 sec. The AHI is one indicator of obstructive sleep apnea, although it is recognized as an imperfect diagnostic tool. An AHI of 30 or more events in an hour indicates severe sleep apnea; 15 to 29 events suggests moderate apnea; and 5 to 14 events indicates mild apnea.
