In general anesthesia, gas exchange was altered by shunt and uneven ventilation perfusion ratios. Lung atelectasis was a cause of impaired oxygenation. High-flow nasal cannula oxygen thera...
The aim of this study is to determine the effect (on PaO2) of a modified mask associated to nasal cannula used for high flow oxygenation.
The aim of this study is to compare exercise capacity in COPD patients through two different systems of supplemental oxygen delivery: High Flow Nasal Cannula Oxygen (HFNCO) and The Venturi...
Pre-oxygenation with high-flow nasal cannula oxygen has been evaluated in a limited number of studies and seems to be better than traditional preoxygenation with a tight fitting mask. Oxyg...
Millions of patients undergo upper GI endoscopy in the United States each year. A large number of these patients have anesthesia to assist with their comfort during the procedure. The majo...
High-flow nasal oxygen (HFNO) has recently gained popularity during administration of anesthesia in a variety of circumstances, including apneic oxygenation. Fully qualified anesthesiologists provide ...
High flow nasal therapy (HFNT) is a technique in which humidified and heated gas is delivered to the airways through the nose via small nasal prongs at flows that are higher than the rates generally a...
Upper airway obstruction during anesthesia is the leading cause of complications during sedation, intubation, and emergence. Devices to support oxygenation and ventilation are costly, require capital ...
The delivery of oxygen is a key component of anaesthetic practice. High flow nasal oxygen therapy is a relatively new addition to more traditional means of oxygenation which provides heated and humidi...
Inhalation of oxygen aimed at restoring toward normal any pathophysiologic alterations of gas exchange in the cardiopulmonary system, as by the use of a respirator, nasal catheter, tent, chamber, or mask. (From Dorland, 27th ed & Stedman, 25th ed)
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
The facial skeleton, consisting of bones situated between the cranial base and the mandibular region. While some consider the facial bones to comprise the hyoid (HYOID BONE), palatine (HARD PALATE), and zygomatic (ZYGOMA) bones, MANDIBLE, and MAXILLA, others include also the lacrimal and nasal bones, inferior nasal concha, and vomer but exclude the hyoid bone. (Jablonski, Dictionary of Dentistry, 1992, p113)
Inhalation anesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anesthetic gas and oxygen are added so that no anesthetic escapes into the room. Closed-circuit anesthesia is used especially with explosive anesthetics to prevent fires where electrical sparking from instruments is possible.
Fluid obtained by irrigation or washout of the nasal cavity and NASAL MUCOSA. The resulting fluid is used in cytologic and immunologic assays of the nasal mucosa such as with the NASAL PROVOCATION TEST in the diagnosis of nasal hypersensitivity.
