Introduction: Snoring, Sleep Apnea, and Seeking Answers

Snoring can be more than just a loud and annoying bedtime soundtrack; it might be a clue to a more serious issue called obstructive sleep apnea (OSA). OSA is characterized by frequent pauses in breathing during sleep.  If you're suspecting you have this sleep disorder, you're not alone, it is currently estimated that upwards of 1 in 4 people are dealing with this nighttime disruptor.

To fully analyze the true extent of the issue one must first venture down the path of sleep apnea testing.  While no one is overly excited to do a sleep test, it is a very important step in formulating a proper diagnosis and recommending appropriate treatment options.  

If there is concern that sleep apnea may be present, a medical provider will recommend one of two types of tests; either the Home Sleep Apnea Test (HST) or the In-Lab Polysomnography (PSG). Today, we'll explore the pros and cons of each test to help you understand the differences, ensuring you can enjoy more restful nights and healthier days ahead.

Advantages of Home Sleep Apnea Testing

The Comforts of Testing at Home

HST offers the convenience of testing from the cozy confines of your bed. Say goodbye to unfamiliar sleep clinics and hello to your own familiar surroundings.    It's like having a portable sleep detective right in your bedroom, quietly gathering essential data while you sleep.  Since you are in a natural environment your sleep quality will be more comparable to that of a normal night.   

A Budget-Friendly Option

If you are budget-conscious, HST might be the way to go. Typically, more affordable than in-lab PSG, HST offers a cost-effective means of evaluating your sleep patterns and identifying potential sleep apnea.  For most people, especially if insurance is involved, the tests are only a few hundred dollars at most.  

Easy to Use

As technology continues to advance, so does the equipment needed.  Over the last several years the tests have become much smaller and more user-friendly.  Wearable technology is getting better at sensing various body metrics without needing to hook up to a multitude of hoses and wires.  Some are so small they almost look like a smartwatch, yet they still can detect various measurements like sleeping position, heart rate, oxygen levels, snoring, and apnea events.  

Disadvantages of Home Testing

User Error

While the equipment typically comes with straightforward instructions for use, it is always possible that something gets missed or messed up.  If a sensor is placed on the body incorrectly or falls off during sleep, that can skew the data improperly leading to inaccurate results.  It is always a drag when you go through the whole testing process only to discover that the data is no good and needs to be redone.   

Under Estimating the Numbers

One of the biggest downfalls of HST is that the equipment does not actually know if you are awake or asleep.  It's estimating that information based on movement or arterial tone, but it is essentially more of an educated guess. Remember, if you spend half the night awake staring at the ceiling, you are sure to be breathing, so the true severity of the OSA may be underreported.  It is important to note, if the results of the test don’t seem like they are lining up with the symptoms you are experiencing, it may be worth a second look. 

Less Information for the Doctors 

While in lab testing is quite cumbersome, it provides an extraordinary amount of information.  On the other hand, the data supplied by home testing equipment is sometimes quite sparse.  Depending on the type of equipment used there may only provide 4 or 5 channels of information, compared to 12 channels on a PSG.  Some equipment may not provide information like sleeping position, snoring intensity, or sleep quality which can be useful when making treatment decisions.

Advantages of In-Lab Polysomnography 

A More Comprehensive Analysis

While PSG does require a trip to the sleep lab, it truly is a sleep exploration extravaganza. Imagine a sleep wonderland equipped with sensors, monitoring systems, and sleep technologists attending to the most minute details of your nocturnal escapades. PSG captures an extensive range of sleep parameters, providing a very accurate and comprehensive analysis of your overall sleep quality.

Tailored for Complex Cases

PSG shines in its ability to diagnose not only sleep apnea but a whole range of other sleep disorders and underlying medical conditions. If you suspect more than just sleep apnea might be affecting your slumber, PSG is well-suited to explore the full picture of your overall sleep health as it is much better at detecting small issues that may be lurking in the shadows.

During an in-lab test, a sleep technician is monitoring you the entire night.  They can intervene if there is an equipment malfunction or if they identify a problem.  They are also able to pinpoint the exact moment you fall asleep, as well as what type of sleep you are in (REM vs Non-REM) so they can provide a perfect roadmap of not only the quantity but the quality of sleep that you get.  

Disadvantages of PSG 

Delays and Expenses:

It stands to reason that completing an in-lab study is a much more labor-intensive ordeal.  Because a single technician can only monitor four or five people at a time, and there must be a bed available, it can often take several months to be seen by a sleep lab.  This can significantly delay the diagnosis as well as the path to treatment.  Because there are far more resources involved in the process, the cost is generally much higher as well.

Foreign and Uncomfortable:

Most sleep labs are somewhat sterile and hospital-like, they don’t often provide that same at-home cozy feel.  This can make it difficult for people to relax, especially those already struggling with nighttime troubles.  As stated earlier a PSG collects 12 different pieces of information about your body's physiology and what it is doing during sleep.  Because of that, there are multiple sensing leads, wires, and hoses attached to your body during sleep. They are stuck everywhere from the top of your head to your chin, chest, fingers, and legs so it is not surprising that people are not going to sleep their best on the night of the test.   

Part 3: The Ultimate Question - HST vs. PSG

Convenience vs. Comprehensive Data

As you contemplate your sleep testing choices, consider what matters most to you and what is the problem you are truly trying to solve. If the speed of diagnosis and convenience of testing at home in a more affordable way is your priority, HST might be your ideal match. On the other hand, people that are on the extreme ends of the spectrum of very mild or very severe sleep apnea may require the more accurate data provided by a PSG.  For those concerned about other sleep disorders outside of OSA, a comprehensive evaluation and in-depth sleep analysis that a sleep lab can provide might be the path to take.

Part 4: Consulting Your Sleep Guide

Making an Informed Decision

Ultimately, the best way to decide between HST and PSG is to consult with a healthcare professional or a sleep specialist. They will carefully assess your sleep concerns, general medical history, and specific goals in order to recommend the most suitable sleep apnea testing option for you.
