Effects of nasal prongs on nasal airflow resistance.
STUDY OBJECTIVES The aim of this study was to investigate whether nasal prongs, which have been proposed to assess nasal flow during sleep, affect nasal airflow resistance (NR). DESIGN NR was estimated by posterior rhinomanometry at a 0.5 L/s flow, under eight conditions: in the basal state, and with seven different nasal prongs. PARTICIPANTS The study was performed in 17 healthy supine sub...
متن کاملCombined effects of a nasal dilator and nasal prongs on nasal airflow resistance.
STUDY OBJECTIVES Nasal prongs (NPs), when used to assess nasal flow, can result in dramatic increases in nasal airflow resistance (NR). The aim of this study was to investigate whether the NP-induced increases in NR could be corrected by the simultaneous use of an internal nasal dilator (ND). DESIGN NR was estimated by posterior rhinomanometry, in the basal state (NRb), and while breathing wi...
متن کاملTreatment of obstructive sleep apnea with continuous nasal airflow delivered through nasal prongs.
We describe a new device for treating obstructive sleep apnea (OSA) which is similar to nasal CPAP, but less cumbersome. The device consists of a 7 mm diameter flexible tube terminating at one end in nasal prongs covered with foam cylinders. The foam cylinders are compressed, inserted into the nostrils and released, forming a tight seal. The other end of the catheter is attached to a compressor...
متن کاملNasal airflow resistance at simulated altitude.
This issue includes an important paper by BARRY et al. [1] in which the changes in nasal peak inspiratory flow (NPIF), and oral peak inspiratory flow (OPIF), during acclimatized exposure to low barometric pressure (equivalent to a simulated altitude of 8000 m, about the height of Mount Everest) of subjects in a hypobaric chamber were analysed. The changes were presumably due to hypoxia and its ...
متن کاملNasal septum injury in preterm infants using nasal prongs 1
OBJECTIVE To assess the incidence and risk factors associated with nasal septum injury in premature infants using reused and new nasal prongs. METHOD The study was a cohort from an open therapeutic intervention. The sample included 70 infants with a gestational age inferior to 37 weeks, who used nasal prongs and were hospitalized at the neonatal service of a hospital in Recife-PE, in the Nort...
