What to expect during your sleep study

Having trouble sleeping? If your doctor has ordered a sleep study, here is what you can expect.

by James Marco Steele, MD

young Hispanic woman sleeping

A good night’s sleep is as important as healthy eating and getting proper exercise. If you’re experiencing difficulty sleeping, we may schedule a sleep study for you after an initial evaluation. There are several different types of sleep studies that can be conducted to assess your sleep condition. You may be a candidate for a sleep study if your evaluation reveals possible sleep apnea symptoms, such as:

  • Chronic snoring.
  • Pauses or gasps during sleep.
  • Excessive daytime sleepiness.
  • Falling asleep at inappropriate times.
  • Trouble falling asleep.

What are the different types of clinical sleep studies?

If you have been recommended for a sleep study, a polysomnogram (PSG) is likely to be ordered. A PSG is an overnight sleep study that records brain activity, eye movements, heart rate, blood pressure, oxygen levels, body movement and more.

Your polysomnogram may include three different types of “in-clinic” studies and/or a home study, based on your insurance and physician’s recommendations.


  • This event may be one or two nights. On the first night, you’ll have general monitoring and diagnostic evaluation. If sleep apnea is discovered, you’ll come back for a second night to determine the right air pressure.

CPAP titration

  • If brought back for a second overnight, your sleep tech will determine the right air pressure for you. During this event, you will sleep with a CPAP machine on for the entire stay.

Split-night PSG with CPAP titration

  • This study can be approved either by your doctor’s recommendations and/or your insurance provider’s requirements (if sleep apnea is discovered or strongly suspected during the first part of the night’s study). The second half of the night is used to determine the CPAP pressure needed to offset apnea.

What is a home study?

Some insurance providers require patients to do a home study instead of an in-clinic study. At NCMA Sleep Centers, an in-clinic appointment will be scheduled, where a NCMA sleep tech will fit a modified version of the monitor onto the patient. Afterward, the patient will sleep overnight at home with the monitor. Data will be retrieved afterward to be reviewed by your doctor. Sometimes, there are issues that prevent collecting all the data we need from a home study. If there are two “failed” studies with the at-home device, we then will perform an “in-clinic” stay.

What can I expect after my sleep study is done?

Studies typically take between two to three weeks for data to be transmitted and read by a doctor. Your results may come back sooner. Our front office staff will contact you regarding next steps at the soonest availability.

If a continuous positive airway pressure (CPAP) machine is recommended, our staff will work to get you set up with a durable medical equipment (DME) company that provides and services safe, reliable CPAP equipment.

Patients using a CPAP machine are typically required to have a one-year compliance check with their doctor. Our office and your DME company will review compliance regulations and keep you informed.

Sleep plays an important role in your physical health. With the data from a sleep study, you and your doctor will be able to work out a plan to get you back to more successful sleeping habits.

NCMA ENT Dr. Stephanie Su Huang invites donations to support rural Zimbabwe project

Dr. Stephanie Su Huang, Northern California Medical Associates Otolaryngologist (ENT) was originally part of a volunteer medical team led by Dr. Jim Palleschi to work at Chidamoyo hospital in June of 2017. Chidamoyo Christian Hospital is a remote hospital serving a rural poor population in northwest Zimbabwe. Despite many challenges and with the help of international volunteers, it has become a full-service hospital that serves approximately 70,000 patients a year through its in-patient and out-patient services.

Dr. Huang says she served patients at the Chidamoyo hospital for just two weeks, and the experience was life changing. “I watched firsthand countless patients walking in the dark from remote villages (some 200km away), and with no complaint, these patients waited patiently for hours to days to be seen. The resilience they exhibited left me speechless. Something magical happened on that trip, and from that moment, I knew that I had to return.  In April of this year my sons, Lucas and Julian, joined me on a second trip to help those less privileged.” Dr. Huang and her two sons have since set up a fundraiser with the goal of reaching $40,000 in donations with funds going toward the purchase of a new ambulance for the beleaguered community.

“The Chidamoyo Hospital is desperately in need of a new ambulance,” explains Dr. Huang. “The current ambulance is 12 years old and has traveled 273,570 miles on unpaved dirt rocky roads full of potholes that only continue to get worse every year.  And the only paved portion of the road has not been serviced or maintained in over 37 years. The ambulance is utilized about eight times per week and covers a range up to 200 miles per trip. On its most recent journey, two windows fell off, one on the poor patient (who fortunately was not harmed), and the other on the dirt road.“

Zimbabwe is a country of around 13 million with over 90 percent unemployment leaving most people to live a life of poverty and struggle. Chidamoyo Christian Hospital has been in operation for more than 50 year and receives no funding or support from the Zimbabwe government. The hospital, clinic, outreach programs, and HIV research projects rely heavily on the lifelong dedication and support of Kathy McCarty. Kathy a Nurse Practitioner who has been working at the rural mission hospital for 38 years. She serves as chief medical officer and won the Pediatric Nursing Association’s Humanitarian of the Year Award in 2008 for her work with the rural poor children of Zimbabwe. Prior award winners include Paul Newman and former First Lady, Roslyn Carter.

“Please join us to help these poor and needy patients and give them a chance to receive the medical care that could save their lives by making a donation to the Chidamoyo hospital.” To make a donation visit the Help Chidamoyo Christian Hospital Purchase a New Ambulance page on the YouCaring network (or follow the Donate Now button below). Donations have so far exceeded $9,000 of the $40,000 goal. All donations are tax-deductible.

Excerpts from New York Times Article 12/19/2010 By CELIA W. DUGGER

Here in this rustic outpost with no phone service and often no electricity, the Chidamoyo hospital and the people who rely on it have entered an unwritten pact to resist the tide of death that has carried away so many. Life expectancy in Zimbabwe, plagued by AIDS and poverty, has fallen to 47 years from 61 years over the past quarter century.

Patients provide the crops they grow and the animals they raise — food that feeds the thousands of patients who use the hospital — and the hospital tends to their wounds, treats their illnesses and delivers their babies. Its two doctors and 15 nurses see about 6,000 patients a month and have put 2,000 people with AIDS on life-saving antiretroviral medicines.

Short of cash like the people it serves, the hospital practices a level of thrift unheard of in the United States. Workers and volunteers steam latex gloves to sterilize them for reuse, filling the fingers with water to ensure against leaks. They remove the cotton balls from thousands of pill bottles to swab patients’ arms before injections. And they collect the tissue-thin pages of instructions from the same bottles for use as toilet paper.

Research reveals new ways to preserve hearing loss after traumatic noise damage

It’s well known that exposure to extremely loud noises — whether it’s an explosion, a firecracker or even a concert — can lead to permanent hearing loss. But knowing how to treat noise-induced hearing loss, which affects about 15 percent of Americans, has largely remained a mystery. That may eventually change, thanks to new research from the Keck School of Medicine of USC, which sheds light on how noise-induced hearing loss happens and shows how a simple injection of a salt- or sugar-based solution into the middle ear may preserve hearing.

To develop a treatment for noise-induced hearing loss, the researchers first had to understand its mechanisms. They built a tool using novel miniature optics to image inside the cochlea, the hearing portion of the inner ear, and exposed mice to a loud noise similar to that of a roadside bomb.

They discovered that two things happen after exposure to a loud noise: sensory hair cells, which are the cells that detect sound and convert it to neural signals, die, and the inner ear fills with excess fluid, leading to the death of neurons.

“That buildup of fluid pressure in the inner ear is something you might notice if you go to a loud concert,” says the study’s corresponding author John Oghalai, MD, chair and professor of the USC Tina and Rick Caruso Department of Otolaryngology — Head and Neck Surgery and holder of the Leon J. Tiber and David S. Alpert Chair in Medicine. “When you leave the concert, your ears might feel full and you might have ringing in your ears. We were able to see that this buildup of fluid correlates with neuron loss.”

Both neurons and sensory hair cells play critical roles in hearing.

“The death of sensory hair cells leads to hearing loss. But even if some sensory hair cells remain and still work, if they’re not connected to a neuron, then the brain won’t hear the sound,” Oghalai says.

The researchers found that sensory hair cell death occurred immediately after exposure to loud noise and was irreversible. Neuron damage, however, had a delayed onset, opening a window of opportunity for treatment.

A simple solution

The buildup of fluid in the inner ear occurred over a period of a few hours after loud noise exposure and contained high concentrations of potassium. To reverse the effects of the potassium and reduce the fluid buildup, salt- and sugar-based solutions were injected into the middle ear, just through the eardrum, three hours after noise exposure. The researchers found that treatment with these solutions prevented 45-64 percent of neuron loss, suggesting that the treatment may offer a way to preserve hearing function.

The treatment could have several potential applications, Oghalai explains.

“I can envision soldiers carrying a small bottle of this solution with them and using it to prevent hearing damage after exposure to blast pressure from a roadside bomb,” he says. “It might also have potential as a treatment for other diseases of the inner ear that are associated with fluid buildup, such as Meniere’s disease.”

Oghalai and his team plan to conduct further research on the exact sequence of steps between fluid buildup in the inner ear and neuron death, followed by clinical trials of their potential treatment for noise-induced hearing loss.

The ability to perceive sound enables one of life’s richest and most meaningful sensory experiences. Approximately 36 million people in the United States suffer from some degree of hearing loss. People of all ages experience symptoms of hearing loss, and these symptoms can lead to serious social problems and depression.
