The N30i Nasal CPAP Mask from ResMed seems to have it all.  A lightweight, comfortable design with an open field of vision that adapts to your movements during sleep, that keeps the tubing up and away from you, and your sleep partner. The top-of-the-head tubing attachment, with a 360 swivel elbow, it keeps the tubing away from your body, to allow you more freedom to keep your favorite sleep position. What's also nice about the N30i is that the entire mask except for the actual cushion is interchangeable with the P30i Nasal Pillow system. Simply swap out the N30i nasal cradle, for the P30i pillow insert. It's that simple.   Product Features: Open Field of Vision Reduces bulk and Claustrophobia Top of Head Hose Connection with 360-Degree Elbow Swivel Starter Pack which includes Three Cushion Sizes to Eliminate Guesswork Whisper Quiet at 24 dBA Hollow-Frame Design with just 3 parts - Minimal Assembly Form Fitting Curved Nasal Cradle Cushion for a Better Seal & Comfort Open Field of Vision Reduces bulk and Claustrophobia. Traditional nasal CPAP masks have historically been heavy, bulky, and have made difficult to enjoy watching TV or reading. The N30i Nasal CPAP mask has addressed the concerns associated with this, by an innovative design using lightweight materials. The result is a lightweight, adaptive mask that allows full field of vision to enjoy wearing your CPAP while watching tv, spending time on a laptop, or reading a book. Top of Head Hose Connection with 360-Degree Elbow Swivel Freedom of movement is important to CPAP users. The Resmed N30i Nasal CPAP mask addresses this issue in two ways. First by placing the approach of the tubing from the CPAP machine to the mask, by attaching at the top of the head. This keeps the tubing away from the front of your body. It also attaches the tubing to the mask with a lightweight 360-degree swivel elbow connector to allow the tubing to adjust as you move. Starter Pack which includes Three Cushion Sizes to Eliminate Guesswork Selecting the right mask is hard enough; what can add to this frustration is not knowing what size cushion is best for you. This is, of course, one of the most important parts of your decision making - proper fit of the cushion. Here at SecondwindCPAP, we love the 'starter pack' option as it eliminates the guesswork. The ResMed N30i Nasal CPAP Mask Starter Pack comes with 3 cushion sizes: small, medium, & small wide. Whisper Quiet at 24 dBA The sound of the air as it moves through the exhalation ports of any CPAP Mask (They all have them), can be a cause of frustration as well. The N30i Nasal Mask puts out about 24 decibels, which is considered whisper quiet. That is, about as quiet as CPAP masks get. Hollow-Frame Design with just 3 parts - Minimal Assembly The ResMed AirFit N30i Nasal Mask with Headgear represents true minimalist design. There are only 3 parts - the frame (with elbow), cushion, and headgear. Although the mask comes to you fully assembled, if ever you want to clean the mask, or replace parts, having only three parts makes disassembly a snap. ResMed has been very thoughtful in the design of this mask. Using lightweight materials, and its patented hollow-frame design, the mask has a lighter-than-air feel to it, yet provides a remarkably stable, comfort seal, even at higher pressures. Form Fitting Curved Nasal Cradle Cushion for a Better Seal & Comfort The nasal cushion for the N30i Nasal Mask has an innovative cradle design that allows it to form-fit around the bottom of your nose. This design works to softly cushion, and cradle the opening of your nose, or nares, to deliver air in a gentle yet consistent seal. The cradle, coupled with the headgear of the N20i, very effectively give a comfortable delivery of air, without sacrificing the need for a superior seal.
