Diathermy smoke: hazardous to health? [PDF]
, 2013 The heat used in electrocautery causes cells to boil and explode, or simply dry up, producing a gaseous by-product known as diathermy smoke. This smoke may have mutagenic and carcinogenic potential, similar to that of cigarette smoke (Spearman et al ...

Pre-oxygenation in obese patients: facemask versus facemask with nasal prong
Malaysian Journal of Anaesthesiology, 2023 Introduction: Anatomical and physiological changes of the respiratory system in obese patients predispose them to rapid oxygen desaturation during apnoea. Adequate pre-oxygenation before anaesthesia induction allows a period of safe apnoea. The efficacy of pre-oxygenation with facemask versus facemask with nasal prong was compared.

Efficacy of facemask resuscitation at birth [PDF]
Pediatric Pulmonology, 1984 The efficacy of facemask resuscitation was assessed by measuring the expiratory tidal volume during the first three inflations in nine babies with birth asphyxia and comparing the results with those obtained in a further nine babies resuscitated after endotracheal intubation. The facemask system was relatively inefficient, with tidal exchange less than

Facemask: Protection or threat?
Marine Pollution Bulletin, 2023 Facemasks were widely used as a protection against SARS-COV-2, which significantly reduced COVID-19 transmission during the pandemic. However, concerns have been raised regarding its adverse impacts on human health due to intense use and mismanagement. Although rampant plastic littering was the norm before the pandemic, the magnitude of the problem is ...

Sensorized Facemask With Moisture-Sensitive RFID Antenna [PDF]
IEEE Sensors Letters, 2021 Due to the ongoing COVID-19 pandemic, the use of filtering facepiece respirators (FFRs) is increasingly widespread. Since the masks' wetness can reduce its filtering capabilities, the World Health Organization advises to replace the FFRs if they become too damp, but currently, there is no practical way to monitor the masks' wetness. A low-cost moisture
