Transtracheal Jet Ventilation

	Transtracheal Jet Ventilation Transtracheal jet ventilation refers to a type of high-frequency ventilation, low tidal volume ventilation provided via a laryngeal catheter by specialized ventilators that are usually only available in the operating room or intensive care unit. This procedure is occasionally employed in the operating room when a difficult airway is anticipated, such as Treacher Collins syndrome, Robin sequence, head and neck surgery with supraglottic or glottic obstruction. It is NOT recommended in emergencies if a person cannot be intubated or ventilated by other means.{{cite journal, last1=Duggan, first1=LV, last2=Ballantyne Scott, first2=B, last3=Law, first3=JA, last4=Morris, first4=IR, last5=Murphy, first5=MF, last6=Griesdale, first6=DE, title=Transtracheal jet ventilation in the 'can't intubate can't oxygenate' emergency: a systematic review, journal=British Journal of Anaesthesia, date=September 2016, volume=117 Suppl 1, pages=i28–i38, pmid=27566790, doi=10.1093/bja/aew192, doi-access=free ...

picture info	High-frequency Ventilation High-frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value. (>150 (Vf) breaths per minute) and very small tidal volumes. High frequency ventilation is thought to reduce ventilator-associated lung injury (VALI), especially in the context of ARDS and acute lung injury. This is commonly referred to as lung protective ventilation. There are different types of high-frequency ventilation. Each type has its own unique advantages and disadvantages. The types of HFV are characterized by the delivery system and the type of exhalation phase. High-frequency ventilation may be used alone, or in combination with conventional mechanical ventilation. In general, those devices that need conventional mechanical ventilation do not produce the same lung protective effects as those that can operate without tidal breathing. Specifications and capabilities will vary depending on the device manufacturer. Physiology With conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Tidal Volume Tidal volume (symbol VT or TV) is the volume of air moved into or out of the lungs during a normal breath. In a healthy, young human adult, tidal volume is approximately 500 ml per inspiration or 7 ml/kg of body mass. Mechanical ventilation Tidal volume plays a significant role during mechanical ventilation to ensure adequate ventilation without causing trauma to the lungs. Tidal volume is measured in milliliters and ventilation volumes are estimated based on a patient's ideal body mass. Measurement of tidal volume can be affected (usually overestimated) by leaks in the breathing circuit or the introduction of additional gas, for example during the introduction of nebulized drugs. Ventilator-induced lung injury such as Acute lung injury (ALI) /Acute Respiratory Distress Syndrome (ARDS) can be caused by ventilation with very large tidal volumes in normal lungs, as well as ventilation with moderate or small volumes in previously injured lungs, and research shows that t ...

picture info	Treacher Collins Syndrome Treacher Collins syndrome (TCS) is a genetic disorder characterized by deformities of the ears, eyes, cheekbones, and chin. The degree to which a person is affected, however, may vary from mild to severe. Complications may include breathing problems, problems seeing, cleft palate, and hearing loss. Those affected generally have normal intelligence. TCS is usually autosomal dominant. More than half the time it occurs as a result of a new mutation rather than being inherited from a person's parents. The involved genes may include ''TCOF1'', ''POLR1C'', or ''POLR1D''. Diagnosis is generally suspected based on symptoms and X-rays, and potentially confirmation by genetic testing. Treacher Collins syndrome is not curable. Symptoms may be managed with reconstructive surgery, hearing aids, speech therapy, and other assistive devices. Life expectancy is generally normal. TCS occurs in about one in 50,000 people. The syndrome is named after Edward Treacher Collins, an English surgeon an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Surgery Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas. The act of performing surgery may be called a surgical procedure, operation, or simply "surgery". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The person or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of the surgeon, the surgeon's assistant, an anaesthetist, a circulating nurse and a surgical technologist. Surgery usually spa ...

	Intubated Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body. Patients are generally anesthetized beforehand. Examples include tracheal intubation, and the balloon tamponade with a Sengstaken-Blakemore tube (a tube into the gastrointestinal tract). Examples * Catheterization * Nasogastric intubation * Tracheal intubation Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic catheter, tube into the vertebrate trachea, trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer ce ...
