Study Objectives:
We assessed the use of mouth tape in patients with mouth breathing during continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea, focusing on CPAP adherence. Additional outcomes included daytime sleepiness (Epworth Sleepiness Scale), snoring (visual analog scale), night awakenings, mouth/throat dryness, leakage, and adverse effects.
Methods:
This randomized crossover study compared CPAP adherence with and without silicone hypoallergenic mouth tape. Participants used each intervention for 30 days, separated by a 1-week washout period. After each period, CPAP data (adherence, apnea-hypopnea index, leakage) and questionnaires were retrieved.
Results:
Sixty-two patients with obstructive sleep apnea (36 males; apnea-hypopnea index [mean ± standard deviation], 45.8 ± 22.2 events/h; age, 57.7 ± 17.6 years; body mass index, 27.9 ± 7.1 kg/m2) were randomly assigned. Participants using mouth tape, compared to those without, showed better CPAP adherence: Average use increased by 51.8 minutes per day (95% confidence interval, 33.1-70.4) and by 41.4 minutes per used day (95% confidence interval, 27.9-55.0). Frequency of use increased by 14.2% (95% confidence interval, 9.3-19.0), with 17.6% more days reaching ≥ 4 hours/night (95% confidence interval, 12.7-22.6). Good adherence increased with an odds ratio of 4.5. Mouth tape statistically improved Epworth Sleepiness Scale score, snoring visual analog scale, mouth/throat dryness, and night awakenings. Adverse effects were reported.
Conclusions:
Using mouth tape in patients with mouth breathing during CPAP improved CPAP adherence in both duration and frequency. Unfavorable symptoms related to obstructive sleep apnea or CPAP were alleviated, leading to better sleep quality.

01:30Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
01:26Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...
