Oxygen is used in many clinical scenarios, however the variable performance of nasal cannulae makes determining the precise fraction of inspired oxygen (FiO2 ) difficult. We developed a novel method for measurement of the tracheal FiO2 using a catheter placed via bronchoscopy. We investigate the effects of oxygen delivery, respiratory ...

Although dysphagia is a life-threatening problem in patients with Duchenne muscular dystrophy (DMD), the pathophysiology of oral stage dysphagia is yet to be understood. The present study investigated the tongue motor deficit during swallowing in patients with DMD and its relationship with disease-specific palatal morphology. Tongue pressure during swallowing water ...

Advancements in neonatal care have led to the survival of extremely premature babies. In the pursuit of gentle ventilation, neonatologists are more inclined to use nasal intermittent positive pressure ventilation (NIPPV). There is currently no evidence to suggest NIPPV is better than conventional mechanical ventilation (CMV), with respect to the ...

There is little evidence to suggest that bilateral nasal packing increases intra-nasal pressures compared to a single pack (or is well tolerated) for uncontrolled unilateral epistaxis, but it is often performed and justified on those grounds. 15 volunteers were recruited according to strict criteria. Rapid Rhino(®) 5.5 cm anterior packs were ...

BACKGROUND: Obstructive sleep apnea (OSA) in adults has been associated with hypertension, low baroreflex sensitivity (BRS), a delayed heart rate response to changing blood pressure (heart period delay [HPD]), and increased blood pressure variability (BPV). Poor BRS may contribute to hypertension by impairing the control of blood pressure (BP), with ...

Tongue-hold swallow (THS) has the potential to be a resistance exercise not only for the pharyngeal constrictor but for the tongue muscles. To elucidate the physiological mechanisms of THS, this study investigated intraoral pressure generation during THS in relation to different extents of tongue protrusion. Tongue pressure was measured by ...

Neonatal Nasal Intermittent Positive Pressure Ventilation (NIPPV) is an established mode of non-invasive respiratory support for preterm infants. NIPPV can be generated by standard ventilators, although none currently offer synchronised NIPPV (sNIPPV), which has been shown to have benefits over continuous positive airway pressure (CPAP)(1). The specialised flow driver - ...

Velopharyngeal closure plays an important role in preventing air pressure leakage during swallowing and phonation from oropharynx to nasopharynx. Levator veli palatini muscle activity is influenced by oral and nasal air pressure, volume of the swallow bolus and postural changes. However, it is unclear how velopharyngeal closing pressure is affected ...

Tongue-palate pressure is a parameter of considerable interest in the field of dysphagia. Maximum isometric tongue-palate pressures (MIPs) decline in healthy aging and in dysphagia. Functional reserve (FR) is the difference between MIPs and swallowing pressures. Reduced FR is thought to constitute a risk for developing functional swallowing impairments. We ...
