Wearing a face mask affects the speech production. On top of that, the frequency response and radiation characteristics of the face mask depending on the material and shape of the mask adds to the complexity of analyzing speech under face mask. Our target is to separate the effect of muscle constriction and increased vocal effort in speech produced under face mask from sound transmission and ra...

BACKGROUND Aerosol face mask design and the distance at which the face mask is held from the face affect the delivery of nebulized medication to pediatric patients. OBJECTIVE To measure the inhaled mass of nebulized albuterol with 3 types of pediatric face mask, at 3 different distances from the face, with a model of a spontaneously breathing infant. METHODS We compared a standard pediatric...

We report a case of invasive Neisseria sicca/subflava meningitis after a spinal injection procedure during which a face mask was not worn by the proceduralist. The report highlights the importance of awareness of, and adherence to, guidelines for protective face mask use during procedures that require sterile conditions.

In today’s world, the importance of biometric studies is increasing day by day. Biometric face recognition study is the most widely used method in the legal environment. Commonly, face images are used in all identification systems(IDs, driver’s license, passport, etc.). In particular, to improve the social security of city life, automatic face detection and face recognition systems are needed. ...

To provide an alternative device for immobilization of the head while easing claustrophobia and improving comfort, an "open-face" thermoplastic mask was evaluated using video-based optical surface imaging (OSI) and kilovoltage (kV) X-ray radiography. A three-point thermoplastic head mask with a precut opening and reinforced strips was developed. After molding, it provided sufficient visible fac...

Ten junior doctors with no postgraduate anaesthetic experience attempted to ventilate the lungs of 50 anaesthetized patients, using either a laryngeal mask or a Guedel airway and face mask. Success was defined as the production of two successive tidal volumes exceeding 800 ml within 40 s. The failure rate was significantly greater using the laryngeal mask compared with the face mask (P < 0.05) ...
