Auto-titrating CPAPs are machines that automatically adjust your pressure throughout the night to ensure that at all times you are receiving the exact pressure necessary to keep your airway open. Because of this, you do not need to have another sleep study done every time your prescription pressure does not seem to be working for you. The auto machine senses and adjusts to whatever pressure is necessary for your needs. Even the smallest change, such as a loss or gain of only ten pounds, can change the optimal pressure for your therapy. A standard CPAP will not adjust with these changing needs. It would have to be reset. Auto CPAPs sense your new needs and function according to what your body demands. If your are unsure whether or not an auto CPAP is correct for your therapy, please give us a call and we will be happy to help you choose the best machine for your needs!
