Switching From A ResMed Mirage Quattro to a Fisher and Paykel Forma (Full Face CPAP Masks)


I’ve been relatively pleased with the ResMed Mirage Quattro Full Face Mask, especially compared to the ResMed Ultra Mirage Full Face Mask. The Ultra was prone to breaking near the forehead piece, which can be expensive enough when one already needs to replace the headgear and the mask seal from time-to-time on both masks (and probably almost any CPAP mask).

A little over a week ago I decided to look at getting a different type of mask. I knew there was room for improvement, especially after having some bad nights. I also wanted to have at least one spare mask around. Trying to get through even one night without it would be very difficult.

Using ResMed S8 AutoSet II Stats to Track CPAP Effectiveness


If you really want to know how to change/access your settings on a ResMed S8 AutoSet II or an S8 Elite then you can find the instructions on the Change CPAP Pressure Settings page at apneaboard.com. However, I recommend that you first read my comments on this in my Living with a CPAP (Obstructive Sleep Apnea Treatment) page.

A couple of weeks ago I started tracking how I felt after a night of sleep using a calendar. I’ve since graduated to maintaining an Excel spreadsheet that logs this information using a scale of zero to five (zero = severe fatigue, five = well rested). A couple of days ago I started checking the morning’s effectiveness stats and recording that in the same spreadsheet.

:( iMac Hard Drive Replacement (Part 1)


Over the past week, since I last had Time Machine run on the iMac, I purchased a few items from iTunes and downloaded some new e-mails. I decided it was time to run another backup so after work I powered up the iMac.

And then I heard the hard drive click of death…

The only thing that appeared on my screen was a folder icon with a question mark in the middle of it. Unfortunately, it’s very clear that the system hard drive has failed.

A Simple Sleep Journal Via Online Calendar


In an effort to maintain awareness of my sleep patterns I decided to keep a very simple sleep journal. I don’t know how useful this will prove to be though it may help identify trends or problems caused by specific changes in my sleeping habits. My sleep doctor may find the data interesting at my next visit, when he checks up on my CPAP treatment. Rather than sign up for another third-party service, I decided to use a resource I already I had.

I’ve been using MobileMe for a while. I’ll transition to the new iCloud service once it becomes available. In MobileMe I created a new “Sleep Journal” calendar in which I enter information about how well I slept and how I felt the day after. Specifically, each day I add an all-day event with a title that describes how I feel that morning. For example, I’ll enter “Extreme Fatigue”, “Slightly Fatigued”, “Moderately Rested”, or “Well Rested” along with some other descriptions or combinations of those (some days I’m a little bit tired but somewhat rested).

I also add short notes to each entry that may include information about new equipment that I used, when I went to bed, how often I remember waking up, or even if I woke up before or after my alarm clock went off. Eventually, I may create a spreadsheet, database, or chart based on the information.

I don’t enter very many details. My goal was to make it simple and easy to access in order to help ensure that I continue to maintain the log.

Firefox Settings: Always Get Newest Page, Open Tab At Far Right


I’m adding this information here mostly so I won’t have to search for these configuration options again. Every time I install a major version of Firefox I have to go back into about:config and change these settings. I know these work in Firefox 3 and 6. They should work in most other versions. To access these options just type about:config into the address bar, press enter, accept the warning, and then type the name in the search field to filter down to the individual parameter.

Always Get Newest Page

browser.cache.check_doc_frequency: 1

Open New Tab At Far Right

browser.tabs.insertRelatedAfterCurrent: false

Updated 11/03/2011: I added a few more items for loading pages faster, which I found in an external article titled 18 Firefox Tweaks to Improve Speed and Performance, in addition to various other Firefox tip articles, etc.

Increase Page Load Speed

network.http.pipelining: true
network.http.proxy.pipelining: true
network.http.pipelining.maxrequests: 10
nglayout.initialpaint.delay: 0 (must be added by creating a new setting of the Integer type)

Apple App Store


Usually I will try to keep my rants to a minimum. After all, my goal with this blog is to provide useful information for others. I try not to waste space with non-helpful opinions. Tonight I can’t resist the urge to bitch.

When Apple first announced the App Store for OS X I thought that it might be a good idea, but I reserved judgement initially. The idea of having a reliable source to download OS X software is an attractive one. However, the concept that it might become the only source is one that I find disturbing. There’s no indication that’s what will happen.

Well, not directly. But it could become more likely without direct action from Apple.

Improving Battery Life With A New MacBook Pro (15″, MacBookPro8,2)


The Short Version: Using gfxCardStatus to manage the graphics mode made a notable difference. Uninstalling McAfee Security made the most difference.

This week I started using a new 15″ MacBook Pro (MacBookPro8,2) with OS X 10.7 (Lion). It wasn’t long before I noticed a dramatic difference between the battery life of the new MacBook Pro and that of my previous 17″ MacBook Pro, which was about two years old.

In the System Preferences I had noticed that I couldn’t configure the system to only use the integrated, low-power graphics card. Rather, I had to choose to enable “Automatic graphics switching” (in “Energy Saver”) or disable it. If it’s disabled then the computer automatically uses the high-performance, battery-draining graphics card.

Last night I began to suspect that the system wasn’t properly switching to the low-powered card. It turns out that I was almost correct.
