Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
Understand what happens while you sleep. Our specialists use appropriate diagnostic testing to investigate sleep concerns and guide personalized treatment.
Whether snoring has raised concerns about sleep apnea, you wake feeling unrefreshed, or you struggle with ongoing sleep difficulties, a sleep evaluation can help identify the next step.
Dr. Raj Kakar and the Houston Sleep Health team consider your symptoms and medical history before recommending testing. A sleep study may help explain what is interrupting your rest and guide a treatment plan.
Schedule an evaluationSleep studies record information about sleep and the body’s activity during rest. The measurements depend on the test, and can help identify sleep-related breathing problems, movement disorders, or causes of pronounced daytime sleepiness.
Testing is selected to answer a clinical question. Insomnia is usually assessed through your history and sleep patterns; a study may be appropriate when another sleep disorder is suspected.
Evaluate patterns that may suggest sleep apnea or another sleep-related breathing concern.
An attended study can assess sleep stages, awakenings, and movement alongside breathing.
Some concerns, including suspected narcolepsy, may require specialized testing beyond an overnight study.
Houston Sleep Health can help determine which setting and test fit your needs. Home sleep apnea testing and laboratory studies collect different levels of information.
A portable device records selected breathing-related signals while you sleep in your own bed. Depending on the device, these may include airflow, breathing effort, oxygen levels, pulse, and snoring.
The team explains how to fit the sensors, when to use the device, and how to return it. Home testing can help diagnose obstructive sleep apnea in appropriate patients; it does not evaluate every sleep disorder.
Explore home testingA sleep technologist monitors you overnight while sensors record a broader range of information, including brain activity, eye movements, breathing, oxygen, heart rhythm, and muscle activity.
Your sleep physician reviews the recorded data to assess the problem and inform care. An in-lab study may be recommended when more detailed information or treatment assessment is needed.
Explore sleep testingA laboratory study brings several measurements together to show how breathing, movement, and sleep interact throughout the night.
The exact recording setup depends on the study ordered. Your clinician interprets the findings alongside your symptoms and medical history.
Air movement through the nose and mouth, breathing effort, rate, and respiratory events.
Blood oxygen levels and heart activity throughout the recording.
Brain activity and eye movements that help identify sleep stages and interruptions.
Body position, snoring, and leg or muscle movements during sleep.
Your initial evaluation guides the recommendation. Symptoms, medical history, and the suspected sleep disorder all influence which test is appropriate.
Home testing may be suitable when obstructive sleep apnea is suspected. A laboratory study may be needed if home testing is inconclusive or does not explain ongoing symptoms.
Discuss your testing optionsShare your sleep concerns, daytime symptoms, medical history, and any previous sleep-test results.
Your specialist recommends home or laboratory testing based on the question the study needs to answer.
Follow the team’s setup and preparation instructions. In the lab, a technologist monitors the overnight recording.
Your sleep physician interprets the findings and discusses treatment, additional testing, or follow-up as appropriate.
Understand your testing options before your appointment.
Ask our teamThey are tests that record selected aspects of sleep or breathing to help your clinician assess a suspected sleep disorder and plan appropriate care.
Common options include home sleep apnea tests and attended overnight laboratory studies. Some concerns require additional specialized testing, which your clinician can discuss when appropriate.
Your specialist recommends testing after reviewing your symptoms, sleep history, and medical conditions. The choice depends on the suspected disorder and the information needed.
You receive a portable device and instructions for fitting its sensors. Sleep at home as directed, then return the equipment according to the team’s instructions. Sensor types and recording schedules vary.
No. Home sleep apnea tests typically record fewer signals and usually do not measure brain-wave sleep stages. A laboratory study provides more comprehensive monitoring when it is needed.
No. Insomnia is usually evaluated through a clinical history and sleep-pattern review. Your clinician may recommend a study if symptoms suggest another sleep disorder or further investigation is appropriate.
