  Purpose

This research is being done to examine if a nasal cannula can be used to keep the throat open during sleep, thereby treating sleep apnea.

People with sleep apnea and people who snore without sleep apnea may take part in this study. Sleep apnea is a disorder caused by pauses in breathing due to repetitive closure of the throat. The most common form of treatment for sleep apnea is continuous positive airway pressure (CPAP) therapy. While CPAP therapy remains the simplest and most effective treatment for snoring and sleep apnea, patients have to wear a nasal mask throughout the night. For this reason, patients often have difficulty sticking to therapy.

Participants enrolled in this study will spend 3-nights in a sleep laboratory. In all nights, the investigators will monitor your sleep and your breathing throughout the night. The investigators will apply several electrodes (sensors) to your scalp and face to monitor your sleep and breathing, and other sensors to your chest, abdomen, cheek, and a finger to monitor your breathing and oxygen level.

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Change in inspiratory airflow [ Time Frame: 2 nights ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in sleep apnea severity (AHI) [ Time Frame: 2 nights ] [ Designated as safety issue: No ]
  • Change in Ratio of apnea-to-hypopnea events [ Time Frame: 2-nights ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: July 2004
Groups/Cohorts Assigned Interventions
Sleep apnea
Patients with diagnosed obstructive sleep apnea
 Device: Trans Nasal Insuflation (TNI) [nasal canula]

Trans Nasal Insuflation, or TNI, uses air at flow rates delivered through a small nasal canula to reduce the severity and frequency of sleep apnea events.

By using TNI we hope to increase the amount of air that the patient can breathe during periods of obstructive sleep disordered breathing.
