To treat OSA, nasal CPAP (Continuous Positive Airway Pressure) was developed in 1981 by Dr Colin Sullivan in Australia. In CPAP treatment, a flow generator unit provides air through a nose mask at a slightly raised pressure which keeps the airway open. The level of air pressure varies according to individual needs. Conventional CPAP treatment is carried out using a constant air pressure which can sometimes make breathing out uncomfortable. Bi-level treatment is an extension to conventional CPAP designed to overcome this. Treatment is carried out in a similar way, except that the flow generator delivers two pressures – a higher pressure when you breathe in and a lower pressure when you breathe out. Your physician will prescribe two pressures: an inspiratory or IPAP pressure for when you breath in; and an expiratory or EPAP pressure for when you breathe out. These pressures are determined during a sleep study and set by the sleep clinic staff or your equipment supplier. The SULLVAN® Comfort™ operates in a spontaneous mode, where it delivers your IPAP and EPAP pressures in response to your breathing pattern. For example, during your inspiratory breath the unit delivers your IPAP pressure; then your expiratory breath triggers the unit to switch to your EPAP pressure. This spontaneous mode of operation is aided by the set IPAP maximum time. This is the maximum length of time, within each breath period, that the flow generator will deliver your IPAP pressure before it switches to your EPAP pressure. Therefore, if your expiratory breath should fail to trigger the unit to switch to your EPAP pressure, the unit will switch automatically when your IPAP maximum time is exceeded. The IPAP maximum time is factory set. For some patients only, the physician will prescribe an individual IPAP maximum time to be set by the sleep clinic staff or equipment supplier. If you feel that you are no longer getting relief from your symptoms of sleep apnea, consult your physician immediately for advice. . . . !" . &'(. If you find the initial sensation of pressure uncomfortable while trying to fall asleep you may use the delay timer. This allows you to select the time it will take (5, 10 or 20 minutes) for the air pressure in your mask to build up gradually to your prescribed pressures. You will have the comfort of relatively low pressures while still awake and the assurance that the required pressures will be reached shortly after you fall asleep. See section 5, Daily operation, for instructions on use. Note: Your physician may recommend that you do not use the delay timer, or use it only to a limited degree. In this case your unit may be set accordingly. . Your Comfort is normally used at home, but it may also be taken with you when you travel. The flow generator has a switch mode power supply which means it can operate on power supplies in other countries without any special adjustment. It can also be used in trucks and recreational vehicles. See section 7, Use in different countries. .
