So what does this mean? Unlike traditional bi-levelbipap where the ipap and epap (your breaths in and breaths out) are determined by the user (you), the st mode has a timed eupneic rate that establishes when you are to breathe in and breathe out. Many customers that call in to speak with our technical staff often asks why anyone would choose a standard cpap machine over an auto cpap machine and the answer really comes down to what your physician feel comfortable with prescribing. Auto cpap machine can also have the range adjusted and what that means is a minimum pressure can be set as well as a maximum, so if you doctor wants you to stay in a range of 6cmh2o to 12cmh2o, the machine is not going to go outside of that range.
The algorithm for the philips respironics device targets peak flow while the resmed device targets minute ventilation, essentially the same common goal with slight variations in delivery method. Bi-level st devices operate with the same ipap and epap concept of traditional bi-levelsbipaps however they carry the fancy st acronym behind their name that means spontaneous timed. The big question that always comes up is why would you need more pressure? The answer is easy, during the course of the night we enter different stages of sleep and some of those stages are deeper and relax the muscles more, especially those that support the airway.
Many of the candidates for auto bi-level have the same determining factors as the standard bi-level candidates listed in the above description for bi-level. There are also certain positions of sleep that make us more prone to sleep apnea events, like sleeping on your back versus sleeping on your side. Its meant to assist in compliance, a person who is non-compliant, meaning they do not use the cpap machine, may benefit from a bi-level device that provides the comfort of exhaling against a lower pressure than the pressure they are breathing in.
For those that do not like to go back to the sleep lab every 1-2 years for a pressure adjustment, this is great because the machine will detect the need for more or less pressure as needed. These specialized servo-ventilators are used for the treatment of complex sleep apnea (compsa), otherwise referred to as cpap induced central sleep apnea (csa), periodic breathing such as cheyne-stokes respiration. Auto cpap machines auto adjusting cpap machines, auto cpap, auto titrating cpap machines auto cpap machines are similar to standard cpap machines in which a single pressure setting is delivered, however this pressure setting can automatically adjust over the night when the machine detects you need more pressure to stabilize the airway.
This simply means that a pressure delivered upon inhalation is higher than the pressure upon breathing out and is beneficial to person that has trouble exhaling against standard cpap pressure. A pressure support number is established to instruct the machine the differences in pressure between the ipap and epap, this pressure setting is typically between 3cmh2o and 6cmh2o. Auto cpap machines can also be programmed to standard or fixed pressure cpap mode, this is beneficial because your treating physician can determine your compliance and ahi (apnea hypopnea index) between the 2 therapy treatments.
Resmed s9 autoset and escape auto, philips respironics system one remstar auto ds560hs, fisher and paykel icon auto , devilbiss intellipap auto, resmart auto bi-level pap therapy uses 2 levels of pressure to treat sleep apnea, an inspiratory pressure (ipap) and an expiratory pressure (epap). The pressure measurements are delivered in a range of 4cmh2o to 20cmh20, however with a standard or fixed pressure cpap machine it will only generate 1 specific setting throughout the entire night (excluding ramp time). While standard or fixed pressure cpap is the most commonly prescribed device, many users are gravitating to auto cpap machines (see more information below). Resmed vpap s, philips respironics system one ds660hs, devilbiss intellipap bilevel auto bi-level devices use a combination of bi-level technology and auto cpap technology and istead of having one fixed ipap pressure and one fixed epap pressure, these two pressure settings auto adjust based on therapy need. Sounds confusing right? Bi-level are less commonly prescribed sleep therapy devices, making up only about 15 of the sleep therapy market.
These devices do not have an auto titrating algorithm, the component used to establish airway patency (keep the airway open) is a fixed pressure and the auto adjusting component is the pressure support which is used to treat the periodic breathing or complex central events. So who are the target candidates for bipap st and vpap st? People that have copd (chronic obstructive pulmonary disease), people that have neuromuscular diseases and people that suffer from obesity hypoventilation. Next step is treatment, right? But which device is right for you? Read the information below to educate yourself and become more involved in your own treatment. Resmed vpap s, philips respironics system one ds660hs, devilbiss intellipap bilevel auto bi-level devices use a combination of bi-level technology and auto cpap technology and istead of having one fixed ipap pressure and one fixed epap pressure, these two pressure settings auto adjust based on therapy need. Philips respironics system one remstar plus ds260hs and remstar pro ds460hs, resmed s9 elite or s9 escape, fisher and paykel icon novo and premo, devilbiss intellipap standard, and transcend travel cpap machine.
The pressure settings are separated by a pressure support threshold of 3-6 cmh2o (example a person on 16cm ipap and 12cm epap have a pressure support of 4cm, the difference between the 2). Listed below are descriptions of the different therapy devices, their target market and a description about therapy delivery. Bi-level is the proper name however most people, physicians included refer to it by a manufacturer trade name of bipap, similar to how most people call cotton swabs q-tips. The results are in and the proof is in black and white you spend more time during the night not breathing than you do breathing. Bless these people that have put up with your snoring night after night and just when they think you have stopped snoring and they can get some rest, they realize you arent breathing.
However these 2 machines differ greatly in therapy delivery and ramp mode is simply a comfort feature that allows the user to fall asleep on a lower pressure while the machine ramps up to the fixed pressure setting, usually over a 20 minute period. People sometimes confuse standard or fixed pressure cpap with auto cpap because their machine comes with a ramp mode feature. A fixed pressure cpap machine delivers pressurized air via a cpap mask (see nasal pillow cpap mask, full face cpap mask, nasal cpap mask) and that pressurized air provides a pneumatic splint in the airway that keeps it from collapsing during sleep. Auto cpap machine can also have the range adjusted and what that means is a minimum pressure can be set as well as a maximum, so if you doctor wants you to stay in a range of 6cmh2o to 12cmh2o, the machine is not going to go outside of that range. Unless specifically prescribed due to other pre-existing conditions, bi-level therapy is typically used for one of these 2 reasons 1. While standard or fixed pressure cpap is the most commonly prescribed device, many users are gravitating to auto cpap machines (see more information below). There are also certain positions of sleep that make us more prone to sleep apnea events, like sleeping on your back versus sleeping on your side. Many sleep labs have a protocol that states when a person gets to a certain pressure threshold to switch them over to bi-level. Its meant to assist in compliance, a person who is non-compliant, meaning they do not use the cpap machine, may benefit from a bi-level device that provides the comfort of exhaling against a lower pressure than the pressure they are breathing in. I have found myself writing a lot of blogs that cater to people that have already been diagnosed and treated for sleep apnea which really isnt fair to the greater percentage of the population that are unaware they even have sleep apnea (80-85 still remain undiagnosed)....
