Nasal strips, designed for humans, in varying colors and sizes

A nasal strip, external nasal dilator strip or nasal dilator strip is a type of adhesive bandage with embedded plastic ribs or splints that is applied across the bridge of the nose and sides of the nostrils, to assist in keeping the airway open. They are believed to make breathing easier and for that reason are used during athletic exertion and as an aid to reduce congestion or to prevent snoring. [1] Various studies have indicated that they do not have a performance-enhancing effect. [2] They are also used by race horse trainers on horses for similar reasons; they are thought to reduce airway resistance and lower the risk of exercise-induced pulmonary hemorrhage (EIPH), plus reduce fatigue and aid post-race recovery.

Human use

In humans, the nasal valve is the narrowest part of the nasal aperture and when exercising, this area is subjected to negative pressure and becomes smaller. [4] Nasal strips adhere to the skin, holding open the anterior nasal aperture and prevent it from collapsing. [5] When properly applied, they lift and widen the space in the nasal passage. They are a drug-free method to maintain airway flow and are available as an over the counter product. [1] They have no reported side effects other than possible skin irritation from the adhesive. [4]

Studies indicate that they are useful in increasing nasal cavity volume in the front three centimeters of the human nose, and for that purpose could be an alternative to decongestive nose sprays, but nasal strips are not particularly helpful for congestion in the posterior nasal apertures. [6] They also have been shown to reduce snoring loudness and improve quality of sleep. Subjects wearing the strips in tests indicated that they believed that the strips helped them breathe more easily, and they are of particular interest to those human athletes who have to wear a mouthguard and need to be able to breathe more through their nostrils than their mouths. Studies have not necessarily demonstrated that athletic performance is increased, but people wearing them seem to have far less dyspnea or shortness of breath while exercising. [7]

Equine use

In horses, they are viewed as helpful because the animals cannot breathe through their mouths, only through their nostrils. As with humans, the equine design helps keep the nasal valve from collapsing due to the negative pressure created by physical exertion. [3] However, their primary benefit is to prevent bleeding in the lungs (EIPH), not to directly enhance performance. The equine version was invented by two veterinarians, James Chiapetta and Edward Blach. In the 1990s, they were inspired by the human product to attempt to create a similar device for horses. They had observed horses on treadmills and saw that, under exertion, the equine nasal passage also narrowed due to the tissue being sucked in. They worked out a licensing agreement with CNS, the company that manufactured the human "Breathe Right" brand of nasal strips in 1997 (now owned by Foundation Consumer Brands) where the company manufactured the equine form of the nasal strip, and paid royalties to Chiapetta and Blach. The equine version was first used publicly at the 1999 Breeders' Cup horse races and the 2000 Summer Olympics. In 2001, they parted ways with CNS and formed their own company, Flair, and in 2008, Chiapetta acquired Blach. [8]

<span class="mw-page-title-main">Nostril</span> Pair of orifices of the nose

A nostril is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through noses, but they do have two small holes used for smelling, which can also be referred to as nostrils.

<span class="mw-page-title-main">Snoring</span> Vibratory sound made while asleep

Snoring is the vibration of respiratory structures and the resulting sound due to obstructed air movement during breathing while sleeping. The sound may be soft or loud and unpleasant. Snoring during sleep may be a sign, or first alarm, of obstructive sleep apnea (OSA). Research suggests that snoring is one of the factors of sleep deprivation.

<span class="mw-page-title-main">Rhinoplasty</span> Surgical procedure to enhance or reconstruct a human nose

Rhinoplasty, commonly called nose job, medically called nasal reconstruction, is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition. Surgery only on the septum is called a septoplasty.

<span class="mw-page-title-main">Positive airway pressure</span> Mechanical ventilation in which airway pressure is always above atmospheric pressure

Positive airway pressure (PAP) is a mode of respiratory ventilation used in the treatment of sleep apnea. PAP ventilation is also commonly used for those who are critically ill in hospital with respiratory failure, in newborn infants (neonates), and for the prevention and treatment of atelectasis in patients with difficulty taking deep breaths. In these patients, PAP ventilation can prevent the need for tracheal intubation, or allow earlier extubation. Sometimes patients with neuromuscular diseases use this variety of ventilation as well. CPAP is an acronym for "continuous positive airway pressure", which was developed by Dr. George Gregory and colleagues in the neonatal intensive care unit at the University of California, San Francisco. A variation of the PAP system was developed by Professor Colin Sullivan at Royal Prince Alfred Hospital in Sydney, Australia, in 1981.

<span class="mw-page-title-main">Adenoid</span> Type of tonsil

In anatomy, the pharyngeal tonsil, also known as the nasopharyngeal tonsil or adenoid, is the superior-most of the tonsils. It is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat. In children, it normally forms a soft mound in the roof and back wall of the nasopharynx, just above and behind the uvula.

<span class="mw-page-title-main">Nasal concha</span> Piece of bone in the breathing passage of humans and other animals

In anatomy, a nasal concha, also called a nasal turbinate or turbinal, is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals. The conchae are shaped like an elongated seashell, which gave them their name. A concha is any of the scrolled spongy bones of the nasal passages in vertebrates.

<span class="mw-page-title-main">Nasal septum deviation</span> Disorder of the nose

Nasal septum deviation is a physical disorder of the nose, involving a displacement of the nasal septum. Some displacement is common, affecting 80% of people, mostly without their knowledge.

Nasal congestion is the partial or complete blockage of nasal passages, leading to impaired nasal breathing, usually due to membranes lining the nose becoming swollen from inflammation of blood vessels.

Mouth breathing, medically known as chronic oral ventilation, is long-term breathing through the mouth. It often is caused by an obstruction to breathing through the nose, the innate breathing organ in the human body. However, by the early 20th century, the term "mouth-breather" had developed a pejorative slang meaning connoting a stupid person.

Exercise-induced pulmonary hemorrhage (EIPH), also known as "bleeding" or a "bleeding attack", refers to the presence of blood in the airways of the lung in association with exercise. EIPH is common in horses undertaking intense exercise, but it has also been reported in human athletes, racing camels and racing greyhounds. Horses that experience EIPH may also be referred to as "bleeders" or as having "broken a blood vessel". In the majority of cases, EIPH is not apparent unless an endoscopic examination of the airways is performed following exercise. This is distinguished from other forms of bleeding from the nostrils, called epistaxis.

<span class="mw-page-title-main">Nasal cartilages</span> Supportive structures in the nose

The nasal cartilages are structures within the nose that provide form and support to the nasal cavity. The nasal cartilages are made up of a flexible material called hyaline cartilage in the distal portion of the nose. There are five individual cartilages that make up the nasal cavity: septal nasal cartilage, lateral nasal cartilage, major alar cartilage, minor alar cartilage, and vomeronasal cartilage.

When we sleep, our breathing changes due to normal biological processes that affect both our respiratory and muscular systems.

<span class="mw-page-title-main">Continuous positive airway pressure</span> Form of ventilator which applies mild air pressure continuously to keep airways open

Continuous positive airway pressure (CPAP) is a form of positive airway pressure (PAP) ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person. The application of positive pressure may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure. CPAP therapy is highly effective for managing obstructive sleep apnea. Compliance and acceptance of use of CPAP therapy can be a limiting factor, with 8% of people stopping use after the first night and 50% within the first year.

<span class="mw-page-title-main">Human nose</span> Feature of the human face

The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.

<span class="mw-page-title-main">Nose</span> Organ that smells and facilitates breathing

A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face and serves as an alternative respiratory passage especially during suckling for infants. The protruding nose that is completely separate from the mouth part is a characteristic found only in therian mammals. It has been theorized that this unique mammalian nose evolved from the anterior part of the upper jaw of the reptilian-like ancestors (synapsids).
