Background and Objectives: Artificial airway suctioning is an important intervention to take care of mechanically ventilated patients. The aim of this research was to determine the effect of artificial airway suction based on the comprehensive criteria for suctioning on the patients' hemodynamic status in ICU. Materials and Methods: This study was a randomized clinical trial by before-after ...
A single-projection X-ray technique showed an increase in functional residual capacity (FRC) in conscious mice in response to aerosolized methacholine (MCh) with little change in airway resistance (Raw) measured using barometric plethysmography (Lai-Fook SJ, Houtz PK, Lai Y-L. J Appl Physiol 104: 521-533, 2008). The increase in FRC presumably prevented airway constriction by offsetting airway c...
Our hypothesis was that the simultaneous activation of tongue protrudor and retractor muscles (co-activation) would constrict and stiffen the pharyngeal airway more than the independent activation of tongue protrudor muscles. Upper airway stiffness was determined by injecting known volumes of air into the sealed pharyngeal airway of the anaesthetized rat while measuring nasal pressure under con...
Asthma is a chronic inflammatory disease characterized by airway hyperresponsiveness (AHR) and reversible airway obstruction. Methacholine (MCh) is widely used in broncho-provocation test to evaluate airway resistance. For experimental investigation, ovalbumin-induced sensitization is frequently used in rodents (Ova-asthma). However, albeit the inflammatory histology and AHR in vivo, it remains...
BACKGROUND We previously identified a MUC5B gene promoter-variant that is a risk allele for sporadic and familial Idiopathic Pulmonary Fibrosis/Usual Interstitial Pneumonia (IPF/UIP). This allele was strongly associated with increased MUC5B gene expression in lung tissue from unaffected subjects. Despite the strong association of this airway epithelial marker with disease, little is known of mu...
macintosh direct laryngoscope has been the most widely used device for tracheal intubation. glidescope video laryngoscope (gvl) has been recently introduced as an alternative device for performing intubation; however, its validity in emergency settings has not been thoroughly evaluated. the aim of this study was to compare macintosh direct laryngoscope versus gvl for emergency endotracheal intu...
