  • Difficulty staying awake during the day
  • Difficulty falling or staying asleep
  • Morning headaches
  • Feelings of no sleep with 8 hours of rest
  • Snoring
  • Sleep Apnea (breathing interruptions during sleep)
  • Restless legs syndrome
  • Low energy or persistent exhaustion
  • Sleepwalking, bedwetting, or nightmares
  • Increased anxiety or irritability
  • Unintentionally kicking your bed partner
  • Uncontrollable blood sugars or hypertension
  • Obesity or difficulty losing weight
  • Sexual dysfunction
  • Poor concentration or memory

Our Services

Full Polysomnogram (PSG):
A PSG is a diagnostic tool used to determine if your patient has a sleep disorder. This test is conducted overnight at the sleep lab in the hospital. This test monitors your patient’s sleep cycles and stages to identify any disturbances caused by their sleep disorder. It will monitor your brain activity, breathing activity, and muscle activity.

CPAP/BiPap Tritration:
CPAP titration studies are conducted overnight in the sleep laboratory. During the study, they will monitor your breathing and adjust the CPAP pressure to determine the proper air pressure required to prevent upper airway blockage, eliminating pauses in your breathing while they sleep.

Multiple Sleep Latency Test (MSLT):
MSLTs are used to test for excessive daytime sleepiness and measure how fast your patient falls asleep in a quiet environment in the daytime. This is a test used to diagnose narcolepsy, and idiopathic hypersomnia.

Split Study:
A split night study is an alternative for patients with severe OSA. This study diagnoses OSA and titrates CPAP in a single night, reducing time to treatment.

Home Sleeping Test:
For patients with a high probability of Obstructive Sleep Apnea (OSA). Patients receive education and instructions in the lab to take a device home to wear overnight and return the device the next day.

BiPAP AutoSV (Auto Servo Ventilation):
For patients with central sleep apnea, complex sleep apnea and periodic breathing, BiPAP AutoSV is designed to deliver optimal ventilation with minimal intervention.

EEG (Electroencephalogram) Testing:
A test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you’re asleep. This activity shows up as wavy lines on an EEG recording.

Millions of people had trouble sleeping last night. Not seeking the appropriate help leads to heightened stress and anxiety, as well as high blood pressure, daytime sleepiness, and in serious cases, psychological issues. Fortunately, most sleep disorders are treatable once they are diagnosed. Clarion Hospital’s Sleep Lab is here to provide those tools to end your sleepless nights.
