Face mask ventilation is a life saving technique. This article will review aetiology and patophysiological consequences of inadequate mask ventilation. The main focus will be on circulatory changes during induction of anesthesia, before and in a short period after intubation that could be attributed to inadequate mask ventilation in humans.

BACKGROUND Adequate ventilation is the key to successful neonatal resuscitation. Positive pressure ventilation (PPV) is initiated with manual ventilation devices via face masks. These devices may be used with a manometer to measure airway pressures delivered. The expiratory tidal volume measured at the mask (V(TE(mask))) is a good estimate of the tidal volume delivered during simulated neonatal...

BACKGROUND Infants and children with respiratory conditions are often prescribed bronchodilators. Face masks are used to facilitate the administration of nebulized therapy in patients unable to use a mouthpiece. Masks incorporate holes into their design, and their occlusion during aerosol delivery has been a common practice. Masks are available in different sizes and different dead volumes. The...

Face masks are recommended to reduce the transmission of many viruses, especially SARS-CoV-2. Therefore, automatic detection whether there is a mask on face, what type worn, and how it worn an important research topic. In this work, use thermal imaging was considered analyze possibility detecting (localizing) as well check possible classify face. The previously proposed dataset images extended ...

Face mask detection has made considerable progress in the field of computer vision since start Covid-19 epidemic. Many efforts are being to develop software that can detect whether or not someone is wearing a mask. methods and strategies have been used construct face models. A created model for detecting masks described this paper, which uses “deep learning”, “TensorFlow”, “Keras”, “OpenCV”. Th...
