Glossopharyngeal Breathing
Glossopharyngeal breathing (GPB, glossopharyngeal insufflation, buccal pumping, or frog breathing) is a means of pistoning air into the lungs to volumes greater than can be achieved by the person's breathing muscles (greater than maximum inspiratory capacity). The technique involves the use of the glottis to add to an inspiratory effort by gulping boluses of air into the lungs. It can be beneficial for individuals with weak inspiratory muscles and no ability to breathe normally on their own. The technique was first observed by physicians in the late 1940s in polio patients at Rancho Los Amigos Hospital, in Los Angeles, by Dr. Clarence W. Dail and first described by Dail in 1951 in the journal '' California Medicine''. Both inspiratory and, indirectly, expiratory muscle function can be assisted by GPB. GPB can provide an individual with weak inspiratory muscles and no vital capacity or breathing ventilator-free breathing tolerance with normal alveolar ventilation and perfect safe ...

Lung
The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the air and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their different muscles to support and foster breathing. In earlier tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the main muscle of respiration that drives breathing is the diaphragm. The lungs also provide airflow that makes vocal sounds including human speech possible. Humans have two lungs, one on the left and on ...

Glottis
The glottis is the opening between the vocal folds (the rima glottidis). The glottis is crucial in producing vowels and voiced consonants. Etymology From Ancient Greek ''γλωττίς'' (glōttís), derived from ''γλῶττα'' (glôtta), variant of ''γλῶσσα'' (glôssa, "tongue"). Function Phonation As the vocal folds vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing or pronunciation. Sound production that involves moving the vocal folds close together is called ''glottal''. English has a voiceless glottal transition spelled "h". This sound is produced by keeping the vocal folds spread somewhat, resulting in non-turbulent airflow through the glottis. In many accents of English the glottal stop (made by pressing the folds together) is used as a variant allophone of the phoneme (and in some dialects, occasionally of and ); in some languages, this sound is a phoneme of its own. Skilled players of the Australian di ...

Poliomyelitis
Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 70% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection. Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal-oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral-oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed by ...

Rancho Los Amigos Hospital
Rancho Los Amigos National Rehabilitation Center is a rehabilitation hospital located in Downey, California, United States. Its name in Spanish means 'Friends' Ranch'. History Overview Rancho Los Amigos National Rehabilitation Center, or Rancho, dates back to 1888 when indigent patients from the Los Angeles County Hospital were relocated to what was then known as the Los Angeles County Poor Farm. Physical Therapy and Occupational Therapy were started in the late 1920s. The Rancho rapidly expanded after it was designated as a respiratory center for polio patients in 1951. In 1955, Dr. Vernon L. Nickel developed the halo vest, a device which is still in use to immobilize the cervical spine following severe neck injury or certain types of surgery. Drs. Jacquelin Perry and Robert Waters contributed to advances in pathokinesiology and treatment of spinal cord injuries, and other advances in rehabilitation of orthopedic and neurologic disorders were made in ensuing years. The ...

California Medicine
The ''Western Journal of Medicine'' was a peer-reviewed medical journal. It was established in 1856 as the ''Transactions of the Medical Society of the State of California''. It was renamed ''California State Journal of Medicine'' in 1902 and volume numbering was restarted at 1. In 1924 it was renamed ''California and Western Medicine'' and in 1946 ''California Medicine''. In 1974, it obtained its final title, ''Western Journal of Medicine'', which was styled as ''wjm'' from 1999 on. In 1985, the journal absorbed ''Arizona Medicine''. It ceased publication in 2002 because it was not financially viable any more. The journal was lastly published by the BMJ Group with Michael Wilkes as its editor-in-chief.

Vital Capacity
Vital capacity (VC) is the maximum amount of air a person can inhale after a maximum exhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC). A person's vital capacity can be measured by a wet or regular spirometer. In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease. Furthermore, the vital capacity is used to determine the severity of respiratory muscle involvement in neuromuscular disease, and can guide treatment decisions in Guillain–Barré syndrome and myasthenic crisis. A normal adult has a vital capacity between 3 and 5 litres. A human's vital capacity depends on age, sex, height, mass, and possibly ethnicity. However, the dependence on ethnicity is poorly understood or defined, as it was first established by studying black slaves in the 19th century and may be the result of conflation ...

Duchenne Muscular Dystrophy
Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy that primarily affects boys. Muscle weakness usually begins around the age of four, and worsens quickly. Muscle loss typically occurs first in the thighs and pelvis followed by the arms. This can result in trouble standing up. Most are unable to walk by the age of 12. Affected muscles may look larger due to increased fat content. Scoliosis is also common. Some may have intellectual disability. Females with a single copy of the defective gene may show mild symptoms. The disorder is X-linked recessive. About two thirds of cases are inherited from a person's mother, while one third of cases are due to a new mutation. It is caused by a mutation in the gene for the protein dystrophin. Dystrophin is important to maintain the muscle fiber's cell membrane. Genetic testing can often make the diagnosis at birth. Those affected also have a high level of creatine kinase in their blood. Although there is no know ...

Cyanosis
Cyanosis is the change of body tissue color to a bluish-purple hue as a result of having decreased amounts of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Body tissues that show cyanosis are usually in locations where the skin is thinner, including the mucous membranes, lips, nail beds, and ear lobes. Some medications containing amiodarone or silver, Mongolian spots, large birth marks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. Cyanosis is further classified into central cyanosis vs. peripheral cyanosis. Pathophysiology The mechanism behind cyanosis is different depending on whether it is central or peripheral. Central cyanosis Central cyanosis is caused by a decrease in arterial oxygen saturation (SaO2) and begins to show once the concentration of deoxyhemoglobin in the blood reaches a concentration of ≥ 5.0 g/dL (≥ 3.1 mmol/L ...
