Percutaneous Transtracheal Ventilation
Percutaneous transtracheal ventilation is the delivery of oxygen to the lungs through an over-the-needle catheter inserted through the skin into the trachea using a high pressure gas source is considered a form of conventional ventilation.{{cite journal, vauthors=Mace SE, Khan N , title=Needle cricothyrotomy. , journal=Emerg Med Clin North Am , year= 2008 , volume= 26 , issue= 4 , pages= 1085–101, xi , pmid=19059102 , doi=10.1016/j.emc.2008.09.004 , url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=19059102 Percutaneous transtracheal ventilation may be mistaken for transtracheal jet ventilation, which is not considered conventional ventilation and refers to high-frequency ventilation; a low 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 insp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cricothyroidotomy
A cricothyrotomy (also called cricothyroidotomy) is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema, or massive facial trauma. Cricothyrotomy is nearly always performed as a last resort in cases where other means of tracheal intubation are impossible or impractical. Compared with tracheotomy, cricothyrotomy is quicker and easier to perform, does not require manipulation of the cervical spine, and is associated with fewer complications. However, while cricothyrotomy may be life-saving in extreme circumstances, this technique is only intended to be a temporizing measure until a definitive airway can be established. Indications A cricothyrotomy is often used as an airway of last resort given the numerous other airway options available including standard tracheal intubation and rapid sequence induction which are the common means of establishing ...
