![]() Sleep apnea is a condition where a person stops breathing for any length of time, which can be between a few seconds to a few minutes, while sleeping. The machine pushes air through an individual’s airway passage at a high pressure to help prevent the sleep apnea from happening. It consists of the machine, a mask which is worn over the face by the individual, and a tube running from the machine to the mask. Other studies found the risk of diabetes, stroke, and other medical problems reduce when a machine is utilized.Ī CPAP (continuous positive airway pressure) machine is a medical device used to treat sleep apnea. Research studies show the average life expectancy for a CPAP/BiPAP machine user increases as opposed to the life expectancy of those with sleep apnea who do not use one. The long-term benefit is the improvement of the individual’s cardiovascular functioning and an increase in the ability to focus and concentrate. Therefore, the user will feel rested and ready to start the day. The severe daytime fatigue experienced by those who have sleep apnea will usually go away. The primary short-term benefit of a CPAP/BiPAP machine is a good night’s rest. Because of the loud snoring, those who live with a person who has sleep apnea may also suffer from a lack of sleep. In addition to lack of rest and loud snoring, sleep apnea can cause an increased risk of stroke, cardiac arrhythmia, or other medical problems. ![]() He has been awarded medals by DRDO chairman on two occasions.Approximately 5% of the population suffers from sleep apnea of some type.

Hence, this article will open new avenues for the researchers. ![]() Despite being extensive studies on ZnSe QDs, their magic size counter parts have still not been explored much but it is expected that the intellectual minds may discover its hidden prospects and variety of new applications. Also, as till now only chemical methods are used for the synthesis of magic size ZnSe, this article can trigger the exploration of alternative methods to widen the horizon of their synthesis e.g., researchers may indulge in developing different synthesis processes which can be “greener” using alternate energy sources. These ZnSe MSNCs can be used in various areas such as LEDs, bio-detection techniques, bioimaging, as drug carriers and in solar cells etc. This review talks about general understanding of nanotechnology covering semiconducting QDs especially MSNCs with special focus on the synthesis and characterization of the magic size ZnSe clusters and their possible applications. Since they are cadmium free, they can be used in the biological applications. ZnSe MSNCs (particle size with less than 2 nm) have been of interest for researchers globally for their unique properties such as wide range of optical tunability, high surface-to-volume ratio, and less toxicity. ![]()
