[Pressure] Newbee - 1st Evening Failure
RE: Newbee - 1st Evening Failure
@Sleeprider, i will certainly ask him that and post as soon as i am up and about.

@Sarcasticdave    all will be fine mate. I feel incredibly confident in my Cardiac Specialist.
I am now 59 and that means that I am old enough to forget, but i'm still young enough to learn. Your advice is gratefully accepted, your opinion is highly valued and your patience will probably be tested when assisting me.

Can cardioballistic effect be that very strong?  I consider that in the time between 2:20:00 and 2:20:10 there was a cardioballistic effect (definitely not FOT, as FOT is much more regular and smaller).

   

The effect in our case is much more hefty.  And the real respiration rate is approx. half of the calculated.

RE: Newbee - 1st Evening Failure
Multicast, I don't have a better explanation at this point. We know Snooks is in Afib and heading to cardio version. If the CPAP data can provide an early warning for others in a similar situation, then this could turn out to be valuable information. I think it will be very interesting to follow this case and to see how this changes following his procedure. I have seen a lot of variations in the cardioballistic artifact arena, and especially when combined with central apnea and hypopnea artifacts, but as I said when we spotted this pattern, "this is unique and new to me".

FOT is a 1-cm oscillation at 4/second (4 Hz) and is at a higher frequency, and different amplitude. In Snooks case, his tidal volume and minute vent appear to be calculating correctly, but the respiration rate is off the charts due to the rapid oscillation. It would help to get a closer view of the flow rate chart to actually see the amplitude and frequency. I tried counting it and was getting over 60 cycles per minute, but not anywhere near 240, which would be FOT.

RE: Newbee - 1st Evening Failure
Of course this informations will be most valuable. The main thing is anyhow that Snooks feels alright: good luck to you and all the best! Keep us informed, please.

RE: Newbee - 1st Evening Failure
I was just looking at some older data and am posting this pic of what I believe to be a variant of my plm respiration that looks more like Snooks unique pattern than my more usual plm pattern.  shown at a couple view scales including one close to the x and y scales in Snooks' screenshot in post #107.  I'm not saying Snooks' repetitive pattern, which is more rapid fire than mine, is plm; just noting possible similarities. fwiw.

Hang in there Snooks of the upside down land. Keep us posted OK. I just beat around my new pulmonary doc that is already my old pulmonary doc. He's got the record that he's my doc for 1 week I suppose, from the request for a second opinion within the office to today's phone consult.

Hi Guys,

I'm back home and all appears to have gone ok. Apparently now i'm back in Sinus Rythm and the Cardio Version seems to have rectified the AFIB and also the Arterial Flutter. Fingers crossed that both issues remain under control from now on.

Sadly I did not get the information that we required from the Cardiac Specialist. When he was walking through the ward to the Operational Room where the procedures take place he saw me in the bed, he walked straight over and started talking. He had paperwork on him and explained that the Echocardiogram showed as being very good and better than he expected which is what he indicated 4 weeks ago. He felt comfy about doing the proceedure and that it would have good results. I asked him if he had got the paperwork I sent and his pager went off. He excused himself and stated he had an emergency and he left the Cardiac Ward. About 30 minutes later his #2 came by and explained that Dr Parik was caught up in a critical situation and as such, he would be doing the Cardioversion. He wanted to just ensure that I was comfortable with that.

I was in the ward for 6-7hrs and sadly Dr Parik did not return at any stage. As such, I got absolutely no info at all.  So at this stage I have no useful details to provide you with and it may be unavailable until i next see him or the Pulmonary Specialist.

I used CPAP last night but i had broken sleep and given it was the first night since the Cardioversion i was very keen to see the print out. It was disappointing from the aspect that the respirations still indicate as being 50 which is surprising and somewhat concerning. Im going to adjust Oscar so that it will record higher than 50, let's see how high it goes. Will it exceed 50??  

I have posted last nights Oscar below. I am going to decrease ramp to 5 and increase min pressure by .2 as I want to get to a fixed pressure of 11. I am supposed to be at 12 but given no OSA events are indicated, i figure 11 should be ok.

RE: Newbee - 1st Evening Failure
Your respiratory rate is still at the maximum detection rate, so whatever is causing the 60 cycle per minute respiratory fluctuation is still present. I'll just tell you straight up, I cannot interpret charts with this anomaly, and it's going to take someone with the ability to closely record your respiration rate, tidal volume and minute vent accurately to determine if this is a defect in your current machine, or if it is real. The biggest problem is, I am yet to see a "sleep specialists" that has a clue of how to design and conduct a study that does anything other than determine the bimodal outcome of obstructive apnea or not. I think you should wear an Oximeter to measure pulse and SpO2 for a while...I actually think you should be on a Holter monitor.

RE: Newbee - 1st Evening Failure
Hi Sleeprider.

The Cardiac Spec had me on a Holter for 24hrs in February and again about September. I am assuming that his holter would be checking cardiac issues but also take into account breathing etc??

The Polysomnography Report did mention nocturnal hypoventilation and when discussed with the Lung Specialist he showed me the part where the O2 contents went down and compared the start and finish levels and then the same when the CPAP was being used and the O2 levels at the end of the night were 93% if i recall correctly. So he said that any concerns there were being addressed.

I think when i can I will need to speak to the Lung Specialist because the Cardiac Spec seems happy, so im leaning towards the concerns that were apparent before i started CPAP. But why it is still happening is obviously a very concerning issue. Meanwhile i'm hunting for a new Respitory / Lung Specialist but getting booked in within 4 months or so is almost impossible Sad

Sleeprider, i believe that you have stumbled upon the issue.  I now believe that the machine i am using is incorrectly reading the respirations or is incorrectly recording them.

I have about 10 days data on the same model / make that i hired from Resmed and looking at Respiration Rate, the highest on most is 32.6, one night i did 34.60 and i think it was one night when i had a panic attack (2nd evening) and woke up terrified, i reached 40.2.  Nothing even close to 50.

I wonder if the machine is faulty and given that it is brand new and probably has under 100hrs on it, what actions would you suggest that i take about getting it looked at. Hiring a machine whilst this one is away to be tested could be expensive and problematic at Christmas.

Is it possible the machine is faulty and reading incorrectly??
