Non-invasive forced oscillometry to quantify respiratory mechanics in term neonates.

To determine normative data by forced oscillation technique (FOT) in non-sedated normal term neonates and test the hypothesis that infants with transient tachypnea of the newborn (TTN) have higher resistance (R) and lower reactance (X) on day 1.


Very preterm neonates receiving "aggressive" nutrition and early nCPAP had similar long-term respiratory outcomes as term neonates.

The impact of the consistent implementation of "aggressive" nutrition by means of intensive early neonatal nutritional support up to 40-44 weeks postmenstrual age and the use of nasal continuous positive airway pressure (nCPAP) within the first hour of life on the respiratory function of very premature neonates (VPN) at school age is unclear.

Improving the Clinical Skills and Knowledge of Midwives and Nurses Caring for Late Preterm Neonates.

Due to changes in funding, late pre-term neonates are no longer admitted to neonatal units unless diagnosed with a specific medical condition. Consequently, neonates born at a gestational age of 35 weeks and 0 days to 36 weeks and 6 days are cared for on postnatal wards. Compared with full-term infants, late preterm neonates are at increased risk of hypothermia, hypoglycemia, hyperbilirubinemia, feeding difficulties, respiratory complications, and mortality.


Tracheostomy in Extremely Preterm Neonates in the United States: A Cross-Sectional Analysis.

Bronchopulmonary dysplasia (BPD) and invasive respiratory support is increasing among extremely preterm neonates. Yet, it is unclear if there is a corresponding increase in tracheostomies. We hypothesize that in extremely preterm neonates with BPD, the incidence of tracheostomy has increased.

Acoustic analysis of neonatal breath sounds using digital stethoscope technology.

There is no published literature regarding the use of the digital stethoscope (DS) and computerized breath sound analysis in neonates, despite neonates experiencing a high burden of respiratory disease. We aimed to determine if the DS could be used to study breath sounds of term and preterm neonates without respiratory disease, and detect a difference in acoustic characteristics between them.

Fungal cutaneous microbiome and host determinants in preterm and term neonates.

The neonatal cutaneous mycobiome has not been characterized in preterm infants. Invasive fungal infections in preterm neonates are associated with high mortality. The immaturity of the preterm skin predisposes neonates to invasive infection by skin colonizers. We report the clinical and host determinants that influence the skin mycobiome.

Impulse oscillometry.

Pulmonary function testing involves a battery of tests from the simple pulse oximetry to the cardiopulmonary exercise testing. Impulse oscillometry (IOS) is one of the newly described pulmonary function tests. It is based on the old principle of forced oscillatory technique modified and refined as per research and advances. It involves the use of sound waves during normal tidal breathing, which gives information on oscillatory pressure-flow relationships and eventually resistance and reactance. The resistan...

Patient asynchrony modelling during controlled mechanical ventilation therapy.

Mechanical ventilation therapy of respiratory failure patients can be guided by monitoring patient-specific respiratory mechanics. However, the patient's spontaneous breathing effort during controlled ventilation changes airway pressure waveform and thus affects the model-based identification of patient-specific respiratory mechanics parameters. This study develops a model to estimate respiratory mechanics in the presence of patient effort.

Barriers and enablers of implementing bubble Continuous Positive Airway Pressure (CPAP): Perspectives of health professionals in Malawi.

Preterm birth complications are the leading cause of neonatal deaths. Malawi has high rates of preterm birth, with 18.1 preterm births per 100 live births. More than 50% of preterm neonates develop respiratory distress which if left untreated, can lead to respiratory failure and death. Term and preterm neonates with respiratory distress can often be effectively managed with Continuous Positive Airway Pressure (CPAP) and this is considered an essential intervention for the management of preterm neonates by t...

Tools to assess lung aeration in neonates with respiratory distress syndrome.

Respiratory distress syndrome is a common condition among preterm neonates and . Assessing lung aeration assists in diagnosing the disease and helping to guide and monitor treatment. We aimed to identify and analyse the tools available to assess lung aeration in neonates with respiratory distress syndrome.

Preventing long-term respiratory morbidity in preterm neonates: is there a path forward?

Acute effects of ventilator hyperinflation with increased inspiratory time on respiratory mechanics: randomized crossover clinical trial.

To evaluate the effects of ventilator hyperinflation on respiratory mechanics.

Inspiratory respiratory mechanics estimation by using expiratory data for reverse-triggered breathing cycles.

Model-based lung mechanics monitoring can provide clinically useful information for guiding mechanical ventilator treatment in intensive care. However, many methods of measuring lung mechanics are not appropriate for both fully and partially sedated patients, and are unable provide lung mechanics metrics in real-time. This study proposes a novel method of using lung mechanics identified during passive expiration to estimate inspiratory lung mechanics for spontaneously breathing patients.

Global and Regional Respiratory Mechanics During Robotic-Assisted Laparoscopic Surgery: A Randomized Study.

Pneumoperitoneum and nonphysiological positioning required for robotic surgery increase cardiopulmonary risk because of the use of larger airway pressures (Paws) to maintain tidal volume (VT). However, the quantitative partitioning of respiratory mechanics and transpulmonary pressure (PL) during robotic surgery is not well described. We tested the following hypothesis: (1) the components of driving pressure (transpulmonary and chest wall components) increase in a parallel fashion at robotic surgical stages ...

Assessment of neonatal EEG background and neurodevelopment in full-term small for their gestational age infants.

Delayed brain function development in small-gestational-age (SGA) infants has been reported. We aimed to quantify rates of immature neonatal EEG patterns and their association with neurodevelopment in SGA full-term neonates.

Role of Impulse Oscillometry in Assessing Asthma Control in Children.

Impulse oscillometry is an effort-independent technique of assessment of airway resistance and reactance, and can be performed in children unable to complete spirometry.

Respiratory mechanics during initial lung aeration at birth in the preterm lamb.

Despite recent insights into the dynamic processes during lung aeration at birth, several aspects remain poorly understood. We aimed to characterize changes in lung mechanics during the first inflation at birth and their relationship with changes in lung volume. Intubated preterm lambs (GA=124-127 d; n=17) were studied at birth. Lung volume changes were measured by electrical impedance tomography (V). Respiratory system resistance (R) and oscillatory compliance (C) were monitored by the forced oscillation t...
