Sleep Apnea Tests

Reviewed + Fact Checked by DR. BARDHA CITAKU, Updated August 16, 2023

Do you occasionally awaken, struggling to catch your breath during the night? Such episodes may indicate sleep apnea, a significant health concern that potentially impacts up to 9% of adults. Discover how prompt diagnosis can optimize your sleep and holistic well-being.

Key Insights

  • Polysomnography and at-home sleep tests are primary diagnostic methods for sleep apnea.
  • These tests evaluate breathing regularity, monitor blood oxygen levels, and assess muscular activity related to respiration.
  • While sleep apnea tests are precise and user-friendly for at-home procedures, technology may sometimes pose challenges.
  • A thorough consultation about your test results with a physician aids in understanding the implications and crafting a tailored treatment strategy.

Types of Sleep Apnea Tests

  1. Polysomnography (In-lab Sleep Study)

Polysomnography is a robust diagnostic tool that scrutinizes various physiological functions during sleep, specifically pinpointing Obstructive Sleep Apnea Syndrome (OSAS). The procedure meticulously monitors brain activity, eye movements, muscle activity, and cardiovascular functions to identify abnormalities. Due to its holistic approach, it remains a primary choice among healthcare professionals for diagnosing OSAS.

  1. At-home Sleep Tests

Designed for convenience, at-home tests focus mainly on recording respiratory patterns and measuring oxygen saturation levels in your bloodstream. With over 20 million people potentially suffering from sleep apnea, these tests are instrumental in determining respiratory consistency during sleep. Once the test concludes, the generated data equips physicians to identify potential sleep-related concerns.

What to Anticipate During Sleep Apnea Tests

You’ll be monitored using devices that observe breathing regularity and other relevant physiological markers. Familiarity with the apparatus aids in setting appropriate expectations:

  • Polysomnography Machine: The central device, capturing brain waves, cardiac rhythm, and respiratory pattern.
  • Sensors: Affixed to body regions to record various physiological actions during sleep.
  • Belts: Wrapped around your torso, these evaluate respiratory effort.
  • Oximeter Probe: Measures blood oxygen levels.
  • EKG, EEG, and EMG Leads: Capture heart, brain, and muscle activities respectively.
  • Nasal/Airflow Sensor & Snore Microphone: Document respiratory disturbances and snoring metrics.

Preparation for Sleep Study

A few easy steps can ensure the optimal accuracy of your sleep study:

  • Refrain from caffeine and other stimulants a day prior.
  • Maintain hygiene for precise readings.
  • Opt for comfortable attire.
  • Continue prescribed medicines, if any.
  • Inform the center of specific needs.
  • Adhere to your typical sleep cycle.
  • Heed any specialized directives from medical professionals.

Advantages and Limitations of Sleep Apnea Tests

While sleep apnea tests offer pinpoint accuracy, convenience, and prompt results, potential technological hiccups can pose challenges. However, advancements ensure these tests are steadily refining their diagnostic capabilities.

Interpreting Sleep Study Results with Your Doctor

Post-test, it’s pivotal to engage with your physician to comprehend the results. Such dialogue fosters mutual understanding, paving the way for a custom-tailored intervention plan. Continuous dialogue ensures you harness the full potential of these diagnostic tools, ushering in nights of undisturbed, restorative sleep.

Sleep Apnea Tests FAQs

A sleep apnea test, also known as a polysomnogram or sleep study, is a diagnostic procedure used to evaluate and diagnose sleep-related breathing disorders such as obstructive sleep apnea.

During a sleep apnea test, sensors are placed on the patient’s scalp, face, chest, and legs to monitor various physiological parameters such as brain waves, heart rate, oxygen levels, and respiratory effort while they sleep. This data is recorded and analyzed by medical professionals.

In some cases, patients may be prescribed a home-based sleep apnea test instead of an in-lab study. Home tests typically involve wearing portable monitoring devices that measure certain parameters while sleeping in the comfort of your own bed.

An in-lab polysomnogram usually requires an overnight stay at a specialized facility where you will be monitored while you sleep. The testing period generally starts
