anaesthetic mask gas exposure

Waste anesthetic gas exposure and strategies for solution ...

As inhaled anesthetics are widely used, medical staff have inevitably suffered from exposure to anesthetic waste gases (WAGs). Whether chronic exposure to WAGs has an impact on the health of medical staff has long been a common concern, but conclusions are not consistent. Many measures and equipment have been proposed to reduce the concentration of WAGs as far as possible.

The leakage of anaesthetic gases to the anaesthetist's breathing zone was monitored using a Bruel & Kjaer Multi Gas Monitor, Type 1302 during 50 general anaesthetics employing either spontaneous ...

GAS, PANDA, and MASK:No Evidence of Clinical Anesthetic ...

This is an important update, as most infants undergoing anesthesia and surgery have exposures to anesthetics that are comparable in length to those of infants in the GAS, PANDA, and MASK studies. 11 Thus, as parents and physicians, we can assume that the findings of these studies are relevant to a wide range of infants having general anesthesia for short elective surgical procedures.

Mean waste anaesthetic gas levels in the PBZ exceeded the NIOSH‐recommended 2 ppm exposure limit in 50 out of 60 (83%) control group patients and 7 out of 60 (12%) study group patients on first measurement in the recovery room, and in 38 out of 60 (63%) and 0 …

The Effect of the Double Mask on Anesthetic Waste Gas ...

nesthesia in dental offices and assessed the effectiveness of the "double mask." Nine freestanding dental offices had measurements of anesthetic waste gas levels taken before and immediately after implementation of a double-mask system. Levels of nitrous oxide decreased from a median of 40.0 parts per million (ppm; interquartile range [IQR] = 23.0–46.0 ppm, n = 9) to 3.0 ppm, (IQR = 2.3 ...

itoring waste gas exposure by staff. Minimizing Exposure The ACVA has taken the clear position that expo-sure to inhalant agents should be minimized for all staff members, not just women of child-bear-ing age.7 It recommends minimizing the delivery of inhalant anesthetic by mask and chamber. If used, such delivery methods should take place

The Double Mask--A New Local Scavenging System for ...

The double mask, a new concept for local scavenging of anaesthetic gases escaping around face masks and from endotracheal tubes, is described. The system consists of a flexible silicone mask into which the anaesthetic gas mixture is led through a flow distributor which is …

Safety and Health Topics | Waste Anesthetic Gases ...

The anesthetic gases and vapors that leak into the surrounding room during medical procedures are considered waste anesthetic gases. Health care professionals who work in hospitals, operating rooms, dental offices and veterinary clinics, are potentially exposed to waste anesthetic gases and are at risk of occupational illness.
