Molecules will try to adopt the most stable conformation that minimizes strain. For cyclohexane, C 6 H 12, this would be the chair conformation. Letâs see why. If cyclohexane was planar, its structure would look like the picture to the left.
CPAP mask â There are many types of C-PAP masks. There are masks that just cover the nose (nasal cpap mask), and masks that cover just the mouth (oral masks), and of course, nasal-oral masks. There are also masks that are attached to oral appliance mouth devices.
CPAP is a treatment that uses mild air pressure to keep your breathing airways open. Overview It involves using a CPAP machine that includes a mask or other device that fits over your nose or your nose and mouth, straps to position the mask, a tube that connects the mask to the machineâs motor, and a motor that blows air into the tube. CPAP is used to treat sleep-related breathing disorders including sleep apnea. It also may be used to treat preterm infants who have underdeveloped lungs. If your doctor prescribes CPAP over other treatment options for your sleep apnea, your insurance will work with a medical device company to provide you with a CPAP machine and the disposable mask and tube. Your doctor will set up your machine with certain pressure settings.
