Inhalants are a broad range of household and industrial chemicals whose volatile vapors or pressurized gases can be concentrated and breathed in via the nose or mouth to produce intoxication, in a manner not intended by the manufacturer. They are inhaled at room temperature through volatilization or from a pressurized container, and do not include drugs that are sniffed after burning or heating. For example, amyl nitrite (poppers), nitrous oxide and toluene – a solvent widely used in contact cement, permanent markers, and certain types of glue – are considered inhalants, but smoking tobacco, cannabis, and crack cocaine are not, even though these drugs are inhaled as smoke or vapor.
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.
Sevoflurane, sold under the brand name Sevorane, among others, is a sweet-smelling, nonflammable, highly fluorinated methyl isopropyl ether used as an inhalational anaesthetic for induction and maintenance of general anesthesia. After desflurane, it is the volatile anesthetic with the fastest onset. While its offset may be faster than agents other than desflurane in a few circumstances, its offset is more often similar to that of the much older agent isoflurane. While sevoflurane is only half as soluble as isoflurane in blood, the tissue blood partition coefficients of isoflurane and sevoflurane are quite similar. For example, in the muscle group: isoflurane 2.62 vs. sevoflurane 2.57. In the fat group: isoflurane 52 vs. sevoflurane 50. As a result, the longer the case, the more similar will be the emergence times for sevoflurane and isoflurane.
Ashtanga vinyasa yoga is a style of yoga as exercise popularised by K. Pattabhi Jois during the twentieth century, often promoted as a dynamic form of classical Indian (hatha) yoga. Jois claimed to have learnt the system from his teacher Tirumalai Krishnamacharya. The style is energetic, synchronising breath with movements. The individual poses (asanas) are linked by flowing movements (vinyasas).
Inhalation happens when air or other gases enter the lungs.
Exhalation is the flow of the breath out of an organism. In animals, it is the movement of air from the lungs out of the airways, to the external environment during breathing. This happens due to elastic properties of the lungs, as well as the internal intercostal muscles which lower the rib cage and decrease thoracic volume. As the thoracic diaphragm relaxes during exhalation it causes the tissue it has depressed to rise superiorly and put pressure on the lungs to expel the air. During forced exhalation, as when blowing out a candle, expiratory muscles including the abdominal muscles and internal intercostal muscles generate abdominal and thoracic pressure, which forces air out of the lungs.
Oxygen therapy, also referred to as supplemental oxygen, is the use of oxygen as medical treatment. Supplemental oxygen can also refer to the use of oxygen enriched air at altitude. Acute indications for therapy include hypoxemia, carbon monoxide toxicity and cluster headache. It may also be prophylactically given to maintain blood oxygen levels during the induction of anesthesia. Oxygen therapy is often useful in chronic hypoxemia caused by conditions such as severe COPD or cystic fibrosis. Oxygen can be delivered via nasal cannula, face mask, or endotracheal intubation at normal atmospheric pressure, or in a hyperbaric chamber. It can also be given through bypassing the airway, such as in ECMO therapy.
The control of ventilation is the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration.
An oxygen bar is an establishment, or part of one, that sells oxygen for recreational use. Individual scents may be added to enhance the experience. The flavors in an oxygen bar come from bubbling oxygen through bottles containing aromatic solutions before it reaches the nostrils: most bars use food-grade particles to produce the scent, but some bars use aroma oils.
Smoke inhalation is the breathing in of harmful fumes through the respiratory tract. This can cause smoke inhalation injury which is damage to the respiratory tract caused by chemical and/or heat exposure as well as possible systemic toxicity after smoke inhalation. Smoke inhalation can occur from fires of various sources such as residential, vehicle, and wildfires. Morbidity and mortality rates in fire victims with burns are increased in those with smoke inhalation injury. Victims of smoke inhalation injury can present with cough, difficulty breathing, low oxygen saturation, smoke debris and/or burns on the face. Smoke inhalation injury can affect the upper respiratory tract, usually due to heat exposure, or the lower respiratory tract, usually due to exposure to toxic fumes. Initial treatment includes taking the victim away from the fire and smoke, giving 100% oxygen at a high flow through a face mask, and checking the victim for injuries to the body. Treatment for smoke inhalation injury is largely supportive with varying degrees of consensus on benefits of specific treatments.
Oxygen is an American television network owned by the NBCUniversal Television and Streaming division and business segment of NBCUniversal, a subsidiary of Comcast. The channel primarily airs true crime programming and dramas targeted towards women.
Kumbhaka is the retention of the breath in the yoga practice of pranayama. It has two types, accompanied whether after inhalation or after exhalation, and, the ultimate aim, unaccompanied. That state is kevala kumbhaka, the complete suspension of the breath for as long as the practitioner wishes.
Ujjayi is a breathing technique employed in a variety of yoga practices. In relation to yoga, it is sometimes called "the ocean breath." Unlike some other forms of pranayama, the ujjayi breath is typically done in association with asana practice in some styles of yoga as exercise, such as Ashtanga Vinyasa Yoga.
Bad Girls Club is a 2006 American reality television series created by Jonathan Murray for the Oxygen network in the United States. The show focused on the altercations and physical confrontations of seven aggressive, quarrelsome, and unruly women. They were featured on the show as "charismatic tough chicks." The cast, deemed "bad girls," would enjoy a luxurious lifestyle in a mansion for three months, during which they obeyed specified rules. Their lives inside and outside of the house were recorded by a production team.
Ross Mathews is an American television host and personality. He first rose to fame as an intern and a correspondent for The Tonight Show with Jay Leno; he was known as "Ross the Intern" on air.
Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.
A bandha is a kriyā in Hatha Yoga, being a kind of internal mudra described as a "body lock," to lock the vital energy into the body. Bandha literally means bond, fetter, or "catching hold of".
Oxygen: Inhale is the seventh studio album by Canadian rock band Thousand Foot Krutch. It was released on August 26, 2014 in the United States.
The Adiyogi statue is a 34-metre tall (112 ft), 45-metre long (147 ft) and 25-metre wide (82 ft) steel statue of Shiva with Thirunamam at Coimbatore, Tamil Nadu. It is recognized by the Guinness World Records as the "Largest Bust Sculpture” in the world. Designed by Jaggi Vasudev, the founder and head of the Isha Foundation, the statue weighs around 500 tonnes.
The science of yoga is the scientific basis of modern yoga as physical exercise in human sciences such as anatomy, physiology, and psychology. Yoga's effects are to some extent shared with other forms of exercise, though it differs in the amount of stretching involved, and because of its frequent use of long holds and relaxation, in its ability to reduce stress. Yoga is here treated separately from meditation, which has effects of its own, though yoga and meditation are combined in some schools of yoga.
