0539 EVALUATION OF AN INNOVATIVE HEADGEAR DEIGN FOR A POSITIVE AIRWAY PRESSURE INTERFACE SYSTEM: A COMPARISON OF THE IMPACT OF 12 AND 15MM INTERNAL DIAMETER TUBING
Abstract
Introduction:
Positive Airway Pressure (PAP) therapy is an effective means to treat sleep disordered breathing (SDB). The mask is an important component of the therapy experience and mask issues are identified as barriers to acceptance of therapy. To enhance comfort and stability of the mask, a design with tubing incorporated into the headgear was developed. The tubing is available with 12 and 15mm internal diameter. The aim of this trial was to test impact of 12mm compared to the 15mm internal diameter tubing on therapy and subjective preference.
Methods:
In this prospective, randomized crossover study, participants received auto CPAP therapy with one headgear tubing configuration for a 10-day period and then crossed over to the other. Subjective aspects of comfort were measured with a 0 - 10 cm visual analog scale (VAS). Efficacy and pressure data generated by the PAP were analyzed.
Results:
Forty-one compliant PAP participants diagnosed with Obstructive Sleep Apnea were enrolled. The mean age was 55.5 ± 12 years and a majority were male (63%). Although statistically different, there were minimal differences in AHI (2.6 ± 1.3 vs. 2.8 ± 1.4, p=0.043) [12mm vs 15mm tubing, respectively]. Differences in the average PAP pressure were not significant (7.7 ± 2.4 vs. 7.8 ± 2.5, p=0.29). According to the subjective preference VAS scores, the overall comfort rating was higher with the 12mm diameter tubing (9.2 ± 1.5 versus 8.4 ± 2.0, p=0.026). Participants felt that the ability to move was greater (9.2 ± 1.5 vs 8.4 ± 1.5, p=0.032) and rated flexibility of the system higher with the 12mm versus the 15mm tubing. (9.7 ± 0.7 versus 8.3 ± 2.1, respectively, p=0.001) The majority of patients preferred the 12mm tubing (56.7% vs 13.3 %).
Conclusion:
Therapy was comparable between the 12mm and 15mm diameter tubing. Participants rated aspects of comfort higher with the 12mm tubing. These results suggest that the use of a smaller size tube may positively affect therapy. Future research is needed to evaluate the long term impact of the smaller diameter tubing on adherence.

O10 3D-designed custom-made modular headgear for Children using non-invasive ventilation. The ‘COMFORT’ project: Custom-Made Facemasks for Respiratory Therapy
Non-invasive ventilation (NIV) is assisted respiratory support delivered via facemask for people with chronic respiratory failure. Commercial NIV masks are available but masks that fit well are difficult to find for children who have small or asymmetrical facial features. Compromised ventilation can have significant health and quality of life impacts for patients and their families. Previous development of 3D printed custom-made masks to improve comfort, fit and performance of NIV for children revealed that in 45% mask-fit was compromised by poorly-fitting headgear (Willox 2020).1 Parents report that headgear is of ‘paramount’ importance for mask-fit. Design concepts and materials for a custom-made modular headgear were refined using patient and parent/carer feedback until a final prototype was reached. The custom-made headgear was evaluated against a comparator mass manufactured stock headgear using adult volunteers using pre-set levels of headgear strap tension (100g, 200g and 300g). Air leak was demonstrated using leak data from a Nippy Junior Plus ventilator and pressure was measured using a Tekscan F-Socket 9811 pressure sensor array. Air leak measurements at medium tension (200g) were 82 l/min for custom mask/custom headgear, 69 l/min for stock mask/custom headgear and 79 l/min for stock mask/stock headgear. Pressure readings at the nasal bridge at medium load (200g) were 86 g/cm2 for custom mask/custom headgear, 53g/cm2 for stock mask/custom headgear and 123 g/cm2 for stock mask/stock headgear. At medium tension, a stock mask with customised headgear was the optimum combination. 3D printing of silicon is in its infancy therefore 3D custom-made mask technology is evolving; however implementation of custom-made headgear may result in significant patient benefit.

11.15 Attitudes regarding contact in women’s NCAA lacrosse
ObjectiveTo evaluate attitudes of headgear use in women’s lacrosse across multi-stakeholdersDesignCross-sectionalSettingOnline surveyParticipantsWomen’s lacrosse players (n= 70), coaches (n=11 male, n=59 female), and officials (n=9 male, n=21 female)Outcome MeasuresA multi-item survey regarding attitudes in women’s lacrosseMain ResultsThere were significant differences among stakeholders about changes to game-play and the influence of headgear. Players (M=3.2±1.2) were more in agreement to increase contact than coaches (M=2.2±1.3) or officials (M=1.2±.8), χ 2 (2,n=174)=51.0, p<.001 [CI95:.00,.00]. Players (M=2.0±.9) agreed less that women’s lacrosse should remain purely non-contact compared to coaches (M=2.9±1.2) or officials (M=4.1±1.3), χ 2 (2,n=174)=46.8, p<.001 [CI95: .00, .00]. Players (M=3.9±1.1) more strongly agreed that a decision needed to be made about allowing contact compared to coaches (M=3.0±13) or officials (M=2.8±1.5), χ2(2,n=174)=19.4, p<.001 [CI95:.00,.00]. Players (M=3.06 ±1.1) felt fewer penalties were called when headgear was worn compared to coaches (M=3.01±1.1) or officials (M=2.38±1.2), χ2(2,175)=8.9, p=.01 [CI95:.01,.01]. Interestingly, there were no differences among stakeholders in statements about headgear ‘made play more aggressive’, χ2(2,174)=2.6, p=.27 [CI95:.26,.27], ‘makes the head a target’, χ2(2,174)=4.2, p=.12 [CI95:.11,.13], or ‘increases hits to the head’, χ2(2,174)=1.1, p=.56 [CI95:.56,.58]ConclusionsPlayers were more in favor of a progressive game allowing contact and recognizing the influence of headgear where officials and, to a lesser extent, coaches favor the current structure. Future research should investigate risk compensation with headgear implementation.
