OBJECTIVE To compare the outcomes of preterm infants with respiratory distress initiated on either Heated Humidified High Flow Nasal Cannula or Nasal Continuous Positive Airway Pressure as a primary mode of respiratory support. STUDY DESIGN Prospective observational cohort study. SETTING Tertiary care level III neonatal intensive care unit. PARTICIPANTS 88 preterm infants between 28 to 34...

OBJECTIVES The goal was to compare the effect of an improved nasal airway on obstructive sleep apnea (OSA) by use of subjective and objective measures. METHODS A prospective study of 50 consecutive patients with nasal airway obstruction and OSA was carried out. RESULTS Subjectively, nasal breathing improved in 49 (98%) patients, whereas snoring decreased or disappeared in 17 (34%); the rema...

BACKGROUND Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects. METHODS In this prospective study, 43 patients with pituitary adenoma who were candidates for EETSA fr...

Induced nasal obstruction can cause obstructive apnoeas in healthy subjects during sleep, but the relationship between nasal resistance measured during wakefulness and obstructive sleep apnoea syndrome (OSAS) is weak. It was postulated that if the subjects could not breathe through the nose, the oral airway must be used, but if this airway is narrowed as well, then it could precipitate sleep-di...

STUDY OBJECTIVE The upper and lower airways are continuous. While upper airway symptoms are common in COPD patients, with accumulating evidence to suggest increased nasal inflammation, the relationships among upper airway, lower airway, and systemic inflammatory indexes have not been studied. We aimed to confirm that there is heightened nasal inflammation in COPD patients, to test the hypothesi...

Noninvasive measurement of respiratory resistance during nasal ventilatory support could be useful to assess the mechanical status of the patient and to optimize the ventilator settings. The aim was to investigate whether the forced oscillation technique (FOT) applied through a nasal mask allows reliable noninvasive estimation of respiratory resistance (Rrs) in patients with severe chronic resp...

OBJECTIVE To compare the effectiveness of nasal continuous positive airway pressure delivered by Nasal mask vs Nasal prongs with respect to continuous positive airway pressure failure. STUDY DESIGN Randomized, controlled, open label, trial. SETTING Tertiary care level III neonatal unit. PARTICIPANTS 118 preterm infants-gestational age (27-34 weeks) requiring nasal continuous positive airw...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

The nasal cavity is susceptible to chemically induced injury as a result of exposure to inhaled irritants. Some responses of the nasal mucosa to inhaled toxicants are species specific. These species-related differences in response may be due to variations in structural, physiologic, and biochemical factors, such as gross nasal cavity structure, distribution of luminal epithelial cell population...
