New UARS patient? Standard Sleep Study NORMAL.

[palerider]

During the past week, here are her average values. Your thoughts (other than leak seems too high) ?

Leak 0.5 L/sec.

AHI 8.5

AI 3.2

HI 5.8

Pressure 12

30lpm is pretty high for a resmed, without any data though, *shrug* who can say what the issue is.

Agree. Leak is high, but she does not think it's leaking from anywhere expect the exhaust holes.

What data from an S8 are you seeking, other than what is listed above ? It has no card, so cannot use RM or SH software. Don't have the data cable.

A few comments...

I believe the leak data is reporting the median leak value. The acceptable leak value is 0.4 L/sec or 24 L/min. I usually strive to keep both the maximum and 95th percentile below the acceptable leak rate. If you do that the median value falls way off. That would indicate that somewhere, somehow, something is leaking more than it should.

The S8 gets really excited about scoring HI. If a bird farts as it is passing over your house it seems like the S8 will score that as an HI. As a result of this a more realistic HI value is to take the number reported by the S8 and divide it by 2 or 3. This quirk was adjusted with the S9 but remains a problem with the S8.

I was told to pay attention to the AI number and basically ignore the HI number. If I wanted to get a ball park figure for AHI I should take the HI, divide it by at least 2 and add that to the AI number.

As a reference my AI for the last week as well as for the last year is 0.6. My 95th percentile for leaks is 22 L/min with the median at 1.2 L/min.

I use nasal pillows and adjust my mask very loose. As a result my leaks are a little higher and I am fine with that.

Her first sleep study weeks ago was completely normal.

Her AHI was 3.5, RDI = 3.0, TcC02 went to 65 tors most of the study. Lowest 02 saturation was 91. Sleep Efficiency 79%.

I''ve seen the summary and interpretation, but let's see what any of you think.

What was her spontaneous arousals?

[Physician]

What was her spontaneous arousals?

0

What was her spontaneous arousals?

0

I don't know if that is possible? Could it be that they did not score them and put zero instead?

No arousals, but the study was abnormal.

I think:

• A TcpCO2 of 65 mmHg is of great concern in a (relatively) young person;
• AHI cannot exceed RDI; and
• One cannot generally be simultaneously normal and abnormal.

A TcpCO2 of 65 mmHg is of great concern in a (relatively) young person...

Although a TcpCO2 of 65 mmHg is of great concern in pretty much everybody...

Oooops. AHI = 3.0, RDI = 3.0

So would one treat her with CPAP ? If so, why ?

She was NORMAL on her first study was ago.

This new study was NOT normal.

... let's see what any of you think.

I think you should smash yourself upside the head with a 48 ounce ball peen hammer (the big beejeebee):



as hard as you can, 24 times in rapid succession, and if after that you still think there's a problem, come back and post.

well, that should have an effect.

How would a concussion, contusion, subdural hematoma, pain, and a skull fracture answer these valid questions ?
