Ventilating Anterior Nasal Packing after Septoplasty
Anterior nasal packing after septoplasty is commonly employed by most of otorhinolaryngologists for haemostasis and splintage action. However it has complications which are usually manageable but rarely can become fatal particularly in high risk patients. Objectives: Present study was aimed to find out significance of ventilating nasal packing after septoplasty to minimize complications of nasa...
متن کاملCan first responders achieve and maintain normocapnia when sequentially ventilating with a bag-valve device and two oxygen-driven resuscitators? A controlled clinical trial in 104 patients.
BACKGROUND AND OBJECTIVE To evaluate the capability of first responders to achieve and maintain normal ventilation of the lungs of victims employing a bag-valve device and two oxygen-driven resuscitators. METHODS Prospective, controlled, blinded, single-centre clinical trial using a bag-valve device and one of two FR-300 devices, with 20 cmH2O working pressure, and flows of either 24 or 30 L ...
متن کاملGrazing Bifurcations and Chaos of a Hydraulic Engine Mount
The constitutive relationships of the rubber materials that act as the main spring of a hydraulic engine mount are nonlinear. In addition to material induced nonlinearity, further nonlinearities may be introduced by mount geometry, turbulent fluid behavior, temperature, boundary conditions, decoupler action, and hysteretic behavior. In this research all influence the behavior of the system only...
متن کاملPoly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review
Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...
