I notice your setting of 9 cm may be too low. With your edema you should be able to tell whether with the increase of CPAP setting would bring down your edema. Try increase by 1/2 cm,for a week and observe your edema by pressing and see its indentation, or your shoes size. Increase next 1/2 cm for a week . and observe further. Eventually your edema disappeared. Stop increasing for this is the RIGHT VALUE of your CPAP setting. Please do not exceed more than 12cm. Best regards. Remember with all thing remain static ( same food, drink, medication , activities remain the same ) Waiting to hear your dramatic result.
