McKesson Nose Clips are disposable, latex-free, easy-to-use nose clips designed for spirometry testing, but they are also ideal for use during breathing treatments with Peak Flow Meters because they reduce air loss through the nasal cavity for accurate readings and treatments. They feature a blue, plastic design and blue, foam nose pads that are large and soft for enhanced patient comfort and secure positioning as well as spring action for effective positioning thus making them a comfortable fit for all sizes.
