Safety and Risk of Nitrous Dioxide during Labor Literature review

Safety and Risk of Nitrous Dioxide during Labor - Literature review Example Nitrous Oxide is a chemical compound with the formula N ­2O and is an oxide of Nitrogen. This gas is commonly referred to as ‘sweet air’ or ‘laughing gas.’ Inhaling it has a euphoric effect, and this was the motivation behind its use as an analgesia. Since the inception of N ­2 ­Ã‚ ­O analgesia use in the management of pain during labor, studies have been conducted to ascertain the various effects it has, other than the analgesic property.   In the United States, the reported use of N ­2O as a labor analgesia is a minimal 1%. This is the motivation for this review. It is an analysis of the factors that have led to the decreased, to almost nil use of N ­2O analgesia during labor. When used in high doses, N ­2O is a weak anesthetic but, in low doses, it is an analgesic. The low dose use of N ­2O is achieved by using it in 50/50 combination with oxygen gas. When the50% N ­2O is in Oxygen, the mixture is referred to as Entonox. Concerns that have been advanced are in relation to the effect that Entonox has on labor, and birth. Studies have also indicated that N ­2O analgesia during labor affects breastfeeding and the wellbeing of both mother and neonate. There are also possible occupational risks that this method presents to persons who care for mothers during labor. Reviews on the occupational risks and the safety of N ­2O labor analgesia have also been carried out. It is essential for a nurse to be well aware of the risks linked to this method in order to practice safety precaution. This knowledge also makes it possible for the nurse to provide the mother with proper care during labor. The use of N ­2O was recommended earlier, due to its low blood-gas solubility coefficient. The value of 0.47 is indicative of its ability to rapidly equilibrate with blood. When used during labor to manage pain, N ­2O is used intermittently, targeting the peak pain during contractions. The parturient can be trained on how to effectively time peak contraction pain. To attain the near-maximum effect of Entonox, approximately ten breaths are required. The intermittent use ensures that there is a minimal accumulation of N ­2O in blood during, and after use.

Mobile Devices & Applications Lab Report Example | Topics and Well Written Essays - 1750 words

Mobile Devices & Applications - Lab Report Example ristics including unpredictable values and adoption rate uncertainties, network effect uncertainties, as well as unobvious cost and impact characteristics. We expect mobile computing technologies to exhibit the same characteristics. This paper explores the status of mobile development and emerging standards. In particular, we examine mobile design and HCI techniques, 4 Generation technologies, the concept of mobile sensors and technology utilization, as well as trends on mobile applications and possible future directions in their development. The main objective is to identify discernable trends in mobile computing technologies and develop insights on how Emerging Technology Group can promote mobile development projects run by ECC-Mobile Ltd using established development techniques and methodologies. Human-commuter interaction (HCI) designs aims to develop creative interactions that maximize user experience. Creating interactive HCI for mobile devices is an open problem attempting to create powerful mobile computing services and resources via small interfaces. The main challenges in designing HCI for mobile devices relate to both hardware and software challenges. Hardware challenges relate to the limitations in size and weight of mobile devices in consideration of portability purpose of such devices (Huang, 2009). Challenges for hardware interaction design for mobile devices include the problem of limited input facilities, limited output features and designing for mobility (Huang, 2009). Currently, mobile devices use three primary input facilities: keyboard, touch screen stylus, and scroll wheel. The challenge with mobile device keyboards emanates from the limited space for key installation. While stylus and touch screen are good alternatives in smartphones, if the screen is small users’ finger can occlude graphical phone elements. Lastly, scroll wheel provides a suitable solution to the problem of input facilities in smartphones (Huang, 2009). Software
