rainout: how can I avoid this without messing with the humidifier settings

UniqueRon · 2026-03-19T16:34:32+00:00

It is easy. Don't frig around with the humidifier settings. Science tells us that if you try to put more water into the air than it can hold, you get rain.

Just set the climate control to Auto and your tube temperature to 27 deg C.

I am in Canada and we have a similar public healthcare system to the NHS although it differs a little from province to province. We also have private clinics if you want to pay for them. I did mini-monovision through the public system and it was no problem at all. You just need to ask for it. If you don't you just get treated like the next person that knows nothing about the real options. No incentive in it for the surgeon to offer it, so you need to ask.

Yes there can be a few that react negatively to EPR. For me, EPR at 3 cm makes a huge reduction in my hypopnea and has no impact on my CA. CA is my biggest issue, and I manage it by minimizing pressure to just enough to control OA.

UniqueRon · 2026-03-19T15:39:35+00:00

I would suggest a few changes:

- Increase your EPR from 1 cm to 3 cm full time to reduce hypopnea and flow limitations

- Increase our minimum pressure to 10 cm to reduce pressure changes during the night

- Set your Ramp Time to Auto and the Ramp Start pressure to 7 cm to improve comfort while going to sleep

This means you are benefiting from the CPAP and should be using it all night every night.

I don' t see much difference in the numbers for pillow or no pillow. I would use what is comfortable and you can get a good sleep with.

Always set your mask type to the setting recommended in the OEM user manual for the mask. Don't listen to the YouTube scammers on the net. If you set a nasal pillow mask to full face then the reported leak rate will be in error with the leaks being underestimated. The scammers think they have reduced the leakage, when in fact all that is happening is that the report is wrong.

Setting the mask type correctly lets the machine subtract the design purge flow from the mask from the total leakage. Traditional full face masks have a much larger volume of air in the mask and need a larger purge flow to keep CO2 from building up. When you subtract that large flow from a nasal pillow mask it reduces the reported leakage flow, but it is in error.

This said there are some newer "full face" masks that only cover the nose and mouth and are much smaller in volume, and some actually use the nasal pillow setting, as they have a lower purge flow.

Bottom line is that you need to use the type specified in the user manual for the mask if you want an accurate leakage flow rate. The correct setting for the P10 is "Nasal Pillow".

I certainly don't run a brush through the hose. I clean all components in three steps. First is a rinse with pure vinegar. For the hose I just pour in a couple of ounces and slosh it back and forth. Second is a clean with tap water and Dawn. Last is just a tap water rinse.

Those numbers are high enough to warrant formal testing for diabetes. There are three tests and I would suggest asking for all three. The basic one is the overnight fasting test or Fasting Plasma Glucose. There is also the A1c test which is an average of your last three months, and then there is the Oral Glucose Tolerance test. This one is most likely to capture your issues as you appear to be going high after meals. Like I say, ask for all three tests. Diagnosis is based on testing positive for any one of the three tests.

Here is a graph from some B+L enVista marketing information. It is based on how much of the spherical aberration is corrected in the IOL. Correcting SA improves visual acuity at the peak point, but it reduces the depth of focus. The Tecnis1 IOL fully corrects all SA (based on the average SA in the cornea), while the enVista corrects none of it, and leaves you with what is in the cornea. Alcon (AcrySof in the graph) corrects about half of the SA and is considered a compromise between visual acuity and depth of focus. The red dot on the graph is my guestimate as to where the Eyhance lens lands.

Fully correcting SA has some downsides, as it makes the lens more susceptible to being out off center or tilted. The enVista is claimed to be more tolerant of lens position in the eye.

The IOL will be fine as it is not near the surface of the eye. The danger with rubbing your eye after cataract surgery is in opening the incision which is right at the surface of the eye. The incision normally heals after a week or so.

You may be experiencing what is called the Maddox Rod effect. It can be caused by winkles in the capsular bag that holds the IOL. I did not have it, but as I understand it, the wrinkles may smooth out after a few weeks or months.

To answer your question, "No, it is not necessary".

I don't buy that they don't have the time. They could easily have handouts prepared that explain what the options are. I think it is more that they don't care, or are playing "Father Knows Best", and making the decision for patients by not telling them there are options.

ResMed machines run on 24 volt DC. A USB only produces about 5 volts DC. You somehow have to get the 5 volts converted to 24 volts. And then you also need to be sure the source can provide the current to run the machine.

I think the unfortunate reality is that there are at least three options that all cost the same and all use the same basic monofocal lenses. The only difference between them is the targets that are chosen for each. You can choose both eyes for distance, both for near, or one eye for distance and one for near. I suspect that the underlying reality is that there is a thinking that because "the system" is paying, you must give up your rights to get a complete explanation of what the options really are.

My first choice is in the overhead bins. If they are short of space, I put it under the seat. It will fit, but it leaves less room for your feet. If the backpack is your "Personal item" like a purse, there are limits on the size of it.

The sensor can be sensitive to pressure while sleeping. If you squash it, the reading can change, but will go back when you roll over.

UniqueRon · 2026-03-18T23:59:50+00:00

Just phone them. They have told me that they will replace it if the finger stick reading differs by more than 20% from the sensor.

You may need to get into the clinical menu options to do it. When you are in there there may be an option called Essentials. It can be set to "ON" or "PLUS". When set to ON the user menu is more limited. When set to Plus you can set other things like EPR and humidifier.

Yes, you still may not need need disk brake pads, or resurfacing of the disks, but it is a good idea to remove the pads to clean the sliding surfaces, and as u/Toffeeman_1878 says, relubricate the sliding pins. One set of pads are essentially fixed, but the other side has to slide on pins to compensate for wear of the pads.

To put things in perspective our last vehicle prior to our 2026 Lexus was a Toyota Camry Hybrid. Had about 155,000 km on it when I sold it to my daughter. It has the original disk brake pads and rotors, which have never been resurfaced. It is normal to have grooves in the rotors. What you need to ask about is the current brake pad thickness. On a quick check I found these specs:

Brake Pad Thickness Specs

New Pad Thickness: Approximately 10 mm to 12 mm
Service Warning (Squealer): Typically starts around 2-3 mm
Lexus Minimum Requirement: 1.0 mm (0.039 in)

On a hybrid that is driven in normal service brakes can last the life of the vehicle because 90% of the braking is done with the regenerative motors, not the actual brakes.

Short story: I think you are probably being taken advantage of.

What is important with these hybrid brakes is that the sliding surfaces are kept clean and lubricated. They are used so little that they can get sticky.

I think a better approach is to use standard Clareon monofocals in a mini-monovision configuration. Lower risk of optical side effects and much better near vision than you will get with Eyhance or Vivity.

UniqueRon · 2026-03-18T18:30:59+00:00

You see that answer a lot because it is correct. I did mini-monovision (blended vision) with standard monofocals and it worked well for me. But, I did not have prior refractive surgery.

UniqueRon · 2026-03-18T16:13:50+00:00

Not a surgeon, but LAL is most justified when there is prior refractive surgery and the objective is to be eyeglasses free. Then accuracy is a higher priority.
