Background and Study Aim. Common use of surgical face masks is recommended for social individual health due to the COVID-19 pandemic. However, there no systematic report responses organism wearing a mask during different exercises. In this context purpose study was examine impacts one-hour brisk walking.
 Material Methods. A total thirty male (n=16) female (n=14) volunteers (mean age BMI 3...

sage for CICVmanagement. As in the Vortexmodel, this prompts the operator to attempt both supraglottic airway andmask ventilation, then if unsuccessful to move on to surgical intervention. Prompting surgical cricothyroidotomy over cannula cricothyroidotomy is consistentwith the 4thNational Audit Project’s finding of high failure rates for cannula cricothyroidotomy in adults. The summary phrase ...

Mild-to-moderate subglottic and tracheal stenosis can be effectively treated endoscopically, but safe airway management is a key concern. Options have included tracheotomy, jet ventilation, and intermittent apnea technique, each of which has limitations. This article presents the authors’ endoscopic surgical technique using laryngeal mask anesthesia during CO2 laser treatment of subglottic and ...

Airway evaluation and management are of critical importance to providing safe and effective anesthesia. Burn injuries in and around the airway are of particular concern to anesthesia providers. The following is a case report of a 5-year-old patient who had neck contractures and a large hypertrophic scar on his chin secondary to a burn injury. The patient initially was easy to mask ventilate, bu...

Nasotracheal intubation is generally a useful maxillofacial surgery that provides good surgical access for intraoral procedures. When nasotracheal intubation is difficult, laryngeal mask airway (LMA) insertion can be performed, and the flexible LMA™ (FLMA) is also useful for anesthetic management. However, the FLMA provides limited access to the mouth, which restricts the insertion of instrumen...

Although the rate of wearing masks has increased to 97.9%, there is a possibility that gap between mask and face may occur because it does not completely fit face, or virus spread due poor performance mask. Accordingly, many studies are being conducted evaluate masks, measure flow coughing with PIV (Particle Image Velocimetry). However, most these studied inside on surface mask, research partic...

In this paper, with the aim of assessing deterioration speech intelligibility caused by a speaker wearing mask, different face masks (surgical masks, FFP2 homemade textile-based protection and two kinds plastic shields) are compared in terms their acoustic filtering effect, measured placing mask on an artificial head/mouth simulator. For investigating additional effects speaker’s vocal output, ...

We demonstrate a highly elongated (aspect ratio over 500:1) optical breakdown in water produced by a single pulse of a picosecond laser focused with a combination of an axicon and a lens. Locations of the proximal and distal ends of the breakdown region can be adjusted by modifying radial intensity distribution of the incident beam with an amplitude mask. Using Fresnel diffraction theory we der...
