Abstract Introduction Continuous positive airway pressure (CPAP) is a treatment for apnea. With long-term CPAP, changes in electroencephalogram (EEG) include increased delta power (1 - 4Hz) and sigma power (11 - 15Hz, spindle). However, the short-term EEG response to CPAP in a split-night study is less quantified. We recently developed a “brain age” model using sleep EEG features. The brain age index (BAI) is defined as the difference between chronological age and brain age (BA - CA). Here we first quantify how BAI changes during CPAP in the same patient, and then investigate how much brain age features during the diagnostic part can predict the reduction in apnea-hypopnea index (AHI) during CPAP. Methods The dataset consisted of 160 subjects. The average age was 59 years with 53% male, 24% female and 23% unknown. We extracted 480 features including band powers, and then computed the BAIs for both diagnostic and CPAP parts. To predict the reduction in AHI during CPAP, we fit a Bayesian regression model using the brain age features, demographics, and sleep parameters during the diagnostic part, and assessed the feature importance using dominance analysis. Results The BAI from the diagnostic part is significantly reduced compared to BAI during CPAP for the same subject (paired t-test, p < 0.01). The diagnostic part has an average BAI 2.24 years; and the CPAP part -4.75 years. The brain age features that are increased during CPAP include sigma powers in N2 and N3. The prediction of AHI reduction has Pearson’s correlation 0.85. The features predictive of reduced AHI are the diagnostic AHI (explained variance 69%), followed by high/low waveforms during N2 (e.g. K-complex, measured by kurtosis) (8.6%), delta power during REM (4.5%) and N1 (2%). The feature predictive of increased AHI is frontal alpha power during quiet awake (2.6%). Conclusion The average BAI is reduced during CPAP. BAI provides a novel view of the acute response to CPAP in sleep EEG. Future study with more CPAP failure patients has the potential of predicting CPAP failure.

BackgroundUse of bubble continuous positive airway pressure (CPAP) has generated considerable interest in neonatal care, but its comparative effectiveness compared with other forms of CPAP, especially in developed countries, remains unclear.ObjectiveTo systematically review and meta-analyse short-term clinical outcomes among preterm infants treated with bubble CPAP vs all other forms of CPAP.MethodsProspective experimental studies published from 1995 onward until October 2018 comparing bubble versus other CPAP forms in preterm neonates <37 weeks’ gestational age were included after a systematic review of multiple databases using pre-specified search criteria.ResultsA total of 978 articles were identified, of which 19 articles were included in meta-analyses. Of these, 5 had a high risk of bias, 8 had unclear risk and 6 had low risk. The risk of the primary outcome (CPAP failure within 7 days) was lower with bubble CPAP (0.75; 95% CI 0.57 to 0.98; 12 studies, 1194 subjects, I2=21%). Among secondary outcomes, only nasal injury was higher with use of bubble CPAP (risk ratio (RR) 2.04, 95% CI 1.33 to 3.14; 9 studies, 983 subjects; I2=42%) whereas no differences in mortality (RR 0.82, 95% CI 0.47 to 1.92; 9 studies, 1212 subjects, I2=20%) or bronchopulmonary dysplasia (BPD) (RR 0.8, 95% CI 0.53 to 1.21; 8 studies, 816 subjects, I2=0%) were noted.ConclusionBubble CPAP may lead to lower incidence of CPAP failure compared with other CPAP forms. However, it does not appear to translate to improvement in mortality or BPD and potential for nasal injury warrants close monitoring during clinical application.Trial registration numberCRD42019120411.

Background: In India, there is high burden of prematurity in newborns due to high birth rate and lack of good antenatal care. The objective of this study was to compare the outcome (efficacy and safety) of Bubble Continuous Positive Airway Pressure (B-CPAP) machine and Indigenous Bubble Continuous Positive Airway Pressure (I-CPAP) as a primary mode of respiratory support in preterm new-borns with respiratory distress syndrome (RDS). It was a prospective observational comparative study conducted at NICU of a tertiary care teaching hospital of western Gujarat, India, from December 2016 to July 2017.Methods: Eighty-one preterm babies <36 weeks of gestation age with respiratory distress (Silverman Anderson scoring >4) within 6 hours of birth were included (out of 182 preterm newborns with respiratory distress syndrome) and put on respiratory support either with B-CPAP machine (n = 48) or with I-CPAP (n = 33). Outcome was compared in the form of CPAP failure, survival and complication rates.Results: There was no significant difference in the demographic profile of patients in both groups except number of neonates between 1.5-2.5 kg birth weight were significantly high in B-CPAP (45.8%) compared to I-CPAP (33.3%) (p = 0.00074). There were no significant differences in CPAP failure rates in B-CPAP (27%) versus I-CPAP (24.2%). The survival rate (72.9% in B-CPAP) versus (75.7% in I-CPAP) in both groups was also similar (CI 95%, p = 0.774). The complications, such as moderate to severe nasal septal damage, occurred significantly more frequent with B-CPAP machine (47.9%) than on I-CPAP (6%) (CI 95%, p = 0.000062).Conclusions: Efficacy of I-CPAP as a primary mode of respiratory support for preterm new-born with respiratory distress was comparable to B-CPAP. The ease with which it can be assembled makes it a suitable alternative to B-CPAP.

Cpap Failure

Respiratory distress contributes significantly to mortality, and morbidity in preterm infants. The incidence of nasal continuous positive airway pressure (CPAP) failure is remarkably high. There are limited data available regarding nasal CPAP failure in Indonesia, and this study is expected to be a reference in taking preventive measures to reduce mortality and morbidity in preterm infants. To determine predictive factors of nasal CPAP failure in preterm infants with respiratory distress. A retrospective cohort study was conducted in preterm infants with respiratory distress at the Neonatology ward of Dr. Sardjito Hospital during January 2017-July 2019. Chi-square or Fisher’s exact tests, followed by multivariate logistic regression analysis with backward method, was used to identify factors contributing to nasal CPAP failure. A total of 150 infants were included in this study. Fifty-three (37.8%) infants had nasal CPAP failure. Bivariate analysis showed birth weight <1000 g, singleton, APGAR score 4-7, premature rupture of membrane (PROM), Downes score, and initiation of fractional concentration of inspired (FiO2) requirement were all risk factors of nasal CPAP failure. However, only birth weight <1000 g ( P = .022; OR 2.69; CI 95% 1.34-5.44), initial Downes score ( P = .035; OR 2.68; CI 95% 3.10-24.11), and initiation of FiO2 requirement ≥30% ( P = .0001; OR 3.03; CI 95% 2.04-4.50) were significant predictors for nasal CPAP failure by multivariate analysis. Birth weight <1000 g, singleton, initial Downes score, and initiation of FiO2 requirement >30% were significant predictors of nasal CPAP failure in preterm infants with respiratory distress.

Long Term Follow Up

Studies have investigated the applications of Continuous Positive Airway Pressure (CPAP) therapy in the treatment of hypernasality due to velopharyngeal dysfunction (VPD; Cahill et al., 2004; Kuehn, 1991; Kuehn, Moon, & Folkins, 1993; Kuehn et al., 2002). The purpose of this study was to examine the effectiveness of CPAP therapy to reduce hypernasality in a female subject, post-traumatic brain injury (TBI) and pharyngeal flap, who presented with signs of VPD including persistent hypernasality. Improvements in mean velopharyngeal orifice size, subjective perception of hypernasality, and overall intelligibility were observed from the baseline to 8-week post-treatment assessment intervals. Additional long-term assessments completed at 2, 3, and 4 months post-treatment indicated decreases in immediate post-treatment improvements. Results from the present study suggest that CPAP is a safe, non-invasive, and relatively conservative treatment method for reduction of hypernasality in selected patients with TBI. More stringent long-term follow up may indicate the need for repeated CPAP treatment to maintain results.
