A question in regard to the Resmed AutoSet CS 2 CPAP machine?? If anyone is using one of these machines, particularly in Canada, could they please clarify if this unit is the Canadian version of the Resmed Adapt SV used in the USA for Central, Complex, Mixed and Obstructive sleep apnea. Also, in regard to the H2i Humifier that works in conjunction with this machine - does it put out the same volume as the H4i, the latest Resmed technology in humidifiers???
Thanks to all responders in advance.

Re: Resmed AutoSet CS 2
IIRC, the Resmed Autoset CS2 was the name given to the Vpap Adapt SV that was sold outside the US just prior to FDA approval. There were some very minor differences in the 2 models but mostly irrelevant as regards the functioning of the device.blogginsjoe wrote:A question in regard to the Resmed AutoSet CS 2 CPAP machine??

I believe you will find the 2i H/H holds more water than the 4i & 3i (going by the appearance units I have. The 4i was just a 3i modified to hold more water and the base plate in the 4i was enlarged slightly ). I have no issues with the 2i. The 3i can empty in a very dry environment, esp if you moth breathe & use a F/F mask.
The reason for the different names related to the evolution of the machine. In 2001 it was introduced as the Resmed Autoset CS - this was a very heavy & bulky unit inside an enlarged Sullivan IV style (square) case. in approx 2006 or early 2007 the name Autoset CS2 appeared outside the US - the case being the same as the current Vpap Adapt SV. I believe the name is now universally the Vpap Adapt SV.

Re: Resmed AutoSet CS 2
Thought I might add some trivia that relates to the expectations of the Autoset CS & how what some analysts might predict sometimes happens in timeframes & ways they never expected.
The Autoset CS was 1st manufactured in 2000. The 1st non us trials recorded with it began in Jan 2001. In 2002 one analyst wrote the following.
>>
The AutoSet CS is an adaptive servo-ventillator, a more complex device than ResMed's continuous positive airways pressure (CPAP) devices. CPAP is valued at $US400, whereas the AutoSet CS will cost about $US2500.
UBS Warburg healthcare analyst John Deakin-Bell said that over time it was possible that AutoSet CS would become ResMed's main technology, but it would take time to get there.
After gaining US market approval, he said, the company would need time to persuade cardiologists to prescribe this form of treatment.
"It will take time for cardiologists to accept this type of technology because normally they prescribe drugs for cardiovascular treatment," Deakin-Bell said.
Although other companies had similar machines, Deakin-Bell said, ResMed's technology was ahead of its competition.
But he cautioned that the device would not bring in significant revenue for at least two years, and that in the interim ResMed's existing devices for treatment of obstructive sleep apnoea and heart failure would provide most of the revenue.
<<
The reality is it took about 4 more years before the very much modernized Autoset CS 2 appeared outside the US (the blower was and remains revolutionary).
Then In either late 2006 or early 2007 FDA granted approval.
When I 1st saw the specs for the Autoset CS 2 / Vpap Adapt SV, I believed it was possible it would become a self setting machine that could adapt to most OSA & SA & CSR requirements & require very little set up. I wondered if it had the potential to become a self diagnosing xPAP device that literally worked out what was wrong with any patient and adpated accordingly. I even think today the Adapt name was intended to convey the adaptability of this particular machine.
I now think this scenario if it happens this way, will be a lot longer happening that I ever imagined. I still think it can happen (a machine capable of adapting to the patients needs using its own technology to probe the patients respiration). Just recently I explored the specs of the Weinmann SOMNOvent CS machine & am thinking that (apart from the Resmed dual impeller blower) the Weinmann machine may be ahead of the Resmed unit.

Re: Resmed AutoSet CS 2
At last found the photo I have been looking for (for months).
This was the original bulky Resmed Sullivan Autoset CS
It was set up by being attached to a PC via a serial link. Required an expert to configure it, weighed a ton (sort of) and was a bit on the noisy side compared to the later Autoset CS 2.

Method and apparatus for the treatment of cardiac failure, Cheyne Stokes breathing or central sleep apnea are disclosed. A subject is provided with ventilatory support, for example positive pressure ventilatory support using a blower and mask. Respiratory airflow is determined. From the respiratory airflow are derived a measure of instantaneous ventilation (for example half the absolute value of the respiratory airflow) and a measure of longterm average ventilation (for example the instantaneous ventilation low pass filtered with a 100 second time constant). A target ventilation is taken as 95% of the longterm average ventilation. The instantaneous ventilation is fed as the input signal to a clipped integral controller, with the target ventilation as the reference signal. The output of the controller determines the degree of ventilatory support. Clipping is typically to between half and double the degree of support that would do all the respiratory work. A third measure of ventilation, for example instantaneous ventilation low pass filtered with a time constant of 5 seconds, is calculated. Ventilatory support is in phase with the subject's respiratory airflow to the fuzzy extent that this ventilation is above target, and at a preset rate conversely.
<<
Note the 95% target - we have mostly talked about 90% but I think now that the Bipap Auto SV targets to 90% whilst the Vpap Adapt SV is as stated, 95% and that helps explain to me a reason why the Vpap Adapt SV seems to control tighter than the Bipap Auto SV does.

I think this link below could be the patent for the Respironics Bipap Auto SV machine follow on model (adds a new variation called VarPAP Mode)
- so anyone interested can compare it to the other patents from Resmed.
http://patft.uspto.gov/netacgi/nph-Pars ... =7,267,122
I know I have read the above patent before & it appears to be an extension of the Bipap Auto SV in that it states in the patent that it can
1) Provide a min & max for Epap
2) A min & max for Ipap
3) A min and Max peak Flow
It uses the words VarPAP to describe this process. So the above patent says that the invention covered can adjust Epap separately to Ipap in trying to regulate CSR. The current Bipap Auto SV only varies Ipap (to the best of my knowledge) between the settings called IpapMin & IpapMax. Also the current Biap Auto SV automatically calculates av Peak Flow & there are no values to set. Because this patent is dated 2007 I am going to guess it is a future model of the Bipap Auto SV with a new mode called the 'VarPap'.

In an example of an application of the variable positive airway pressure support system, the preferred embodiment of the present invention is connected to a patient as shown in FIG. 2. A caregiver, such as an authorized clinician, doctor, or respiratory therapist, inputs a minimum and maximum IPAP and EPAP levels, as well as a minimum and maximum target peak flow Q.sub.peak(target(max)), Q.sub.peak(target(min)). Initially, the IPAP level is set to the minimum IPAP pressure, EPAP is set to the minimum EPAP pressure, and the target peak flow is set to the minimum target peak flow setting. If the minimum IPAP and EPAP levels are the same, the variable positive airway pressure support system operating in this VarPAP modes is essentially providing a CPAP pressure support treatment at that time, because IPAP=EPAP. The patient then falls asleep with the device running the VarPAP algorithm shown in FIG. 3. If the peak flow Q.sub.peak drops below the target peak flow value Q.sub.peak(target), IPAP is increased by an incremental amount for the next breath.

Here the patent describes how it acts like a Bipap Auto SV but if it thinks that isn't working at normalizing CSR, it starts raising Epap (which I don't believe the current Bipap Auto SV does).

Every 2 to 5 minutes, the patient flow is monitored using performance parameter determination process 106 to determine whether the patient's flow corresponds to a CSR pattern. If so, the target peak flow, EPAP, or both are altered as discussed above. FIG. 10 illustrates a pressure waveform 153 output by the pressure support system that includes changes to both IPAP and EPAP, according to the principles of the present invention. In this illustration, during time interval 150, the patient is receiving repeated patterns of pressure support where the EPAP level 152 is constant and the IPAP level 154 repeatedly increases, as generally indicated at 156, and decreases, as generally indicated at 158. During these intervals, the pressure support system determines, via performance parameter determination process 106 and target peak flow and EPAP adjustment process 104, that the patient is experiencing CSR and is continues to attempt to counteract the CSR by adjusting the target peak flow.
At the beginning of time interval 160, however, the system begins increasing the EPAP level, because altering the peak target flow was not sufficient to counteract the presence of CSR. In other words, the system has switched to the EPAP adjustment mode discussed above. During interval 60, the EPAP level increases, as generally indicated at 162, while the IPAP level also continues to be adjusted by IPAP adjustment process 102. Eventually, either the CSR pattern is resolved, or the EPAP.sub.max level is reached. In either event, the EPAP level is decreased, as generally indicated at 164, during interval 166. During this interval, the peak target pressure is also decreased. Thereafter, the pressure support system exits the EPAP adjustment mode and returns to the peak target pressure Q.sub.peak(target) adjustment mode.

The final part of the patent makes it very clear this is a new yet unannounced PAP mode from Respironics - see the rest to how the machine can be set to swap modes when it detects CSR
QUOTE
>>
Some breathing patterns exhibit the CSR pattern but have minor fluctuations in peak flow. A true CSR pattern shows high peak flow followed by a very low peak flow or an apnea. Thus, in a preferred embodiment of the present invention, a further criteria, in which the maximum peak flow has to be above the threshold, must be met before the patient is considered to be experiencing that hyperpnea phase of a CSR pattern. Likewise, a still further criteria, in which the minimum peak flow has to be below the hypopnea level, must be met before the patient is considered to be experiencing that hyponea phase of a CSR pattern. These thresholds are determined by the clinician and typically based on observation of peak flows during sleep.
In a further embodiment of the present invention, the pressure support system is also adapted to implement other conventional modes of pressure support, such as CPAP, PPAP, BiPAP, for delivering the flow of breathing gas to treat sleep apnea, including obstructive sleep apnea and central apneas, CHF, COPD, or other cardio-pulmonary disorders, either alone or in conjunction with the novel VarPAP pressure support mode for treating CSR of the present invention.
The present invention contemplates that controller 26 implements many of the standard functions of a pressure support device, i.e., providing CPAP, bi-level pressure support BiPAP, PPAP pressure support, smart-CPAP as taught, for example, in U.S. Pat. Nos. 5,203,343; 5,458,137; and 6,087,747 all to Axe et al. the contents of which are incorporated herein by reference, or auto-CPAP as taught, for example, in U.S. Pat. No. 5,645,053 to Remmers et al. the contents of which are also incorporated herein by reference, in addition to implementing the VarPAP mode of pressure support.
In one embodiment of the present invention, the pressure support system includes a mode s e l e c t input device that allows a user or authorized caregiver to s e l e c t the mode of ventilation (VarPAP, CPAP, bi-level, auto-CPAP) under which the pressure support device operates. However, the present invention also contemplates that pressure support system implements the VarPAP mode of pressure support alone.[/i]
In addition, the present invention contemplates performing the CSR detection techniques in the background while implementing a conventional mode of pressure support and then switching the VarPAP mode of pressure support once CSR is detected.

Re: Resmed AutoSet CS 2
Hi,
Thank you for the prompt and thorough repsonse including the trivia! A question that I was remiss in asking was whether the motor in the Adapt SV is Resmed's new version that is supposed to be 75% quieter than their previous models i.e. AutoSet II Series or is it still the original that was in the machine when it first arrived on the scene.
Also, when I first began CPAP trials I was using a Resmed S8 Advantage which seemed much quieter (with no new motor) than the REMstar M Series A-Flex machine that I'm presently testing. I don't believe either is going to address the Central/Complex issues but the Resmed supplier here is ordering a Resmed SV machine that I will be testing prior to and following my 2nd sleep study. Another issue will be what should the initial settings be on the CS 2 when it arrives as I won't have had my sleep study by then and the Dr.'s prescription was left somewhat open-ended i.e. "Trial VPAP for complex sleep apnea" thus no parameters to work off of. I realize that you are not Dr. but with your own experience with this machine what might be the best plan? Of course working in conjunction with my RT who is supplying the machine. Awaiting your response.
Cheers

Re: Resmed AutoSet CS 2
The Autoset CS 2 (Vpap Adapt SV Introduced a new twin impeller blower. That is, rather than the traditional fan at one end of the motor shaft & counter weight at the other, Resmed designed a motor that has a fan at each end thus removing the need for the counterweight & allowing finer balancing of the whole the motor & increasing the acceleration of the airflow for the same energy input (no lost energy on the counterweight). This dual impeller motor greatly lowered fan noise.blogginsjoe wrote:Hi,

I understand a variation of that motor has gone into the S8 II models - I also understand it is that motor that allows for fine tuning the airflow wave form into the shark fin shape that it now produces.
Just a caution re your machine - the doc shd have written trial Vpap SV rather than trial Vpap - some DMEs might mis the point & yes the Vpap Adapt SV (Autoset CS 2) is a good choice for complex sleep apnea in that it addresses Centrals as well as can be baselined for OSA (by setting the epap pressure high enough to eliminate the main obstructions). You could also consider the Bipap Auto SV as it too addresses these conditions.
Good luck - will be very interested to hear what you think of the machine what ever one you get.

Thanks! The SV situation with the prescription is not an issue at this point in time as this machine is being brought in for my trial before and after my sleep study. If it passes the test and addresses my issues, and at the conclusion of my 2nd study, I will have the Dr. include the SV identifier into the prescription that will then be sent to my DME for reimbursement. Good info on this just the same. You didn't mention the noise factor between your two machines (Respironics and the Resmed????) Do you have a personal preference in this regard???

The Respironics Bipap Auto SV tends to be a bit noisy, but it seems to get quieter as the night progresses.
The Vpap Adapt SV is so quiet you can't really hear it - just the air noise from the mask vents.
Wife - loves the Vpap Adapt SV for its quietness. She can accept the Bipap Auto SV (but she would go sleep in another room whenever I used the older Vpap III machine).

Re: Resmed AutoSet CS 2
I have added a whole lot of info into one of the posts above - the one that shows the patents for the Autoset CS & Vpap Adapt SV. I had to edit it 14 times because the cpaptalk system hiccups if the word select appears in the wrong way (thinks it is an embedded SQL command) - it took me 10 or so goes to figure out what was knocking the server over when I submitted the text).
The info on the VarPAP makes so much more sense to me having seen what the Weinmann SOMNOvent CR can do. It looks to me like Respironics are going to release their version of a machine that tries to do all things for all people. The VarPAP is a mode of operation but the proposed machine can do most modes including CPAP, BiPAP, PPAP, AutoPAP as well as VarPAP or it may be released just to do VarPAP alone.
The reason I added it all here is now I know where to look for it as it is very hard info to locate. One has to get the search criteria just right.

It looks to me like Respironics are going to release their version of a machine that tries to do all things for all people. The VarPAP is a mode of operation but the proposed machine can do most modes including CPAP, BiPAP, PPAP, AutoPAP as well as VarPAP or it may be released just to do VarPAP alone.
The reason I added it all here is now I know where to look for it as it is very hard info to locate. One has to get the search criteria just right.
