Contribution of nasal pathways to low frequency respiratory impedance in infants.
BACKGROUND In infants the impedance of the nasal pathways (Zn) is a significant proportion of the total respiratory impedance (Zrs). METHODS In 11 infants Zrs was partitioned into Zn and lower respiratory system impedance (Zlrs) using a nasal catheter. A low frequency oscillatory signal (0.5-20 Hz) was applied during a pause in breathing to obtain the impedance spectra. A model of the respira...
متن کاملFREQUENCY OF HYPOCALCEMIA IN LOW BIRTH WEIGHT INFANTS AT HOSPITALS IN KASHAN IN 1997
Considering the fact that early hypocalcemia is the most common type of neonatal hypocalcemia which manifests during the first few days of Iife (72 hours) and that hypocalcemia in low birth weight neonates is very common, this descriptive study on hypocalcemia was conducted to determine the frequency of hypocalcemia in low birth weight neonates in the city of Kashan in the first 9 months of...
متن کاملRespiratory system impedance from 4 to 40 Hz in paralyzed intubated infants with respiratory disease.
To describe the mechanical characteristics of the respiratory system in intubated neonates with respiratory disease, we measured impedance and resistance in six paralyzed intubated infants with respiratory distress syndrome, three of whom also had pulmonary interstitial emphysema. We subtracted the effects of the endotracheal tube after showing that such subtraction was valid. Oscillatory flow ...
متن کاملThe Effect of Gold Nanoparticle on Electrical Impedance of Tissue on Low Frequency Ranges
Introduction: Electrical impedance of tissues on low frequencies includes useful information about functional and structural changes in tissues. This property is used in Electrical Impedance Tomography (EIT) imaging modality for the detection of lesions in tissues.Objective: The goal of this article is to study changes in electrical impedance of tissues in the presence of gold nanoparticles.Mat...
متن کاملA Comparative Study of Treatment Response of Respiratory Distress Syndrome in Preterm Infants: Early Nasal Intermittent Positive Pressure Ventilation versus Early Nasal Continuous Positive Airway Pressure
Background Infant respiratory distress syndrome (IRDS) is one of the main causes of serious complications and death in preterm infants. Both Nasal Continuous Positive Airway Pressure (NCPAP) and Nasal Intermittent Positive Pressure Ventilation (NIPPV) are known as the most common treatment strategies for IRDS. The present study intended to compare NCPAP and NIPPV in the treatment of preterm inf...
