What is sleep apnea testing?

Sleep apnea testing, or sleep study, is designed to monitor various physiological activities during sleep to detect abnormalities that indicate sleep apnea. These tests are critical for healthcare providers to determine the right course of treatment and can be performed in a sleep lab or at home, depending on the individual’s needs and the severity of the symptoms.

Types of sleep apnea tests

There are two primary types of sleep apnea tests:

  • Polysomnography (PSG): Conducted in a sleep lab, PSG is a comprehensive test that records brain waves, eye movements, muscle activity, heart rhythm, respiratory effort, airflow, and blood oxygen levels during sleep.
  • Home Sleep Apnea Testing (HSAT): HSAT is a simplified version of polysomnography that can be done in the patient’s home. It typically measures respiratory effort, airflow, and blood oxygen levels.

What is a sleep apnea test like to experience?

  • In-lab sleep study: Staying overnight in a sleep lab might seem daunting, but the environment is made to be as comfortable as possible, resembling a hotel room. Technicians are present to ensure everything runs smoothly and to assist the patient as needed.
  • Home sleep test: Home testing offers the convenience of being in your own bed. Instructions are provided on how to apply the sensors and operate the machine, ensuring that reliable data is collected.

Who is a candidate for sleep apnea testing?

Candidates for sleep apnea testing often exhibit symptoms such as:

  • Loud, chronic snoring
  • Long pauses in breathing during sleep, often reported by a partner
  • Excessive daytime sleepiness
  • Morning headaches
  • Waking up with a dry mouth or sore throat
  • High blood pressure, especially if not controlled by medication
  • Obesity
  • Unexplained daytime fatigue and sleepiness
  • Sudden awakenings with a sensation of gasping or choking
  • Poor concentration and memory loss
  • Mood disturbances like depression or irritability

The testing process, step by step

A sleep apnea test typically involves these steps:

  • Preparation: Before the test, patients are advised to avoid caffeine and alcohol, as these substances can affect sleep patterns.
  • Setup: Sensors are placed on the scalp, temples, chest, and legs, and a nasal cannula is used to measure airflow.
  • Monitoring: Throughout the night, the equipment records the patient’s physiological data, which is later analyzed by sleep specialists.
  • Follow-up: After the test, patients will have a follow-up appointment to discuss the results and potential treatment options.

Interpreting test results

The data collected during sleep apnea testing is analyzed to determine:

  • The number of apnea and hypopnea events per hour (Apnea-Hypopnea Index, or AHI)
  • The duration of these events
  • Blood oxygen levels throughout the night
  • Sleep stages and patterns
  • Signs of other sleep disorders
