Bain circuit: respiratory maintenance circuit Laryngoscope: used to view larynx including the vocal cords, the glottis, etc. Endotracheal tube: a tube introduced into the patient's trachea to maintain a patient to ensure that air reaches the lungs for respiration: Laryngeal mask airway (LMA) a less stimulating alternative to an endotracheal ...
The breathing circuit may be open, closed, or semi-closed, depending on whether breathing gas is recycled. A closed or semi-closed circuit will include components which remove carbon dioxide from the exhaled gas and add oxygen before it is delivered for inhalation, so that the mixture remains stable and suitable for supporting life.
The breathing circuit is the ducting through which the breathing gases flow from the machine to the patient and back, and includes components for mixing, adjusting, and monitoring the composition of the breathing gas, and for removing carbon dioxide. A modern anaesthetic machine includes at minimum the following components: [2]
The formation of water by the reaction and the moisture from the respiration also act as a solvent for the reaction. Reactions in aqueous phase are generally faster than between a dry gas and a dry solid. Soda lime is commonly used in closed-circuit diving rebreathers and in the anesthesia breathing circuit in anesthesia systems. [8] [9]
Gordon Jackson Rees died in early 2001, age 82. The Jackson Rees Department of Anesthesia at the Royal Liverpool Children's Hospital is named in his honor. [8] A piece of equipment known as the Jackson-Rees breathing circuit is still sold by medical supply companies. [9]
In its simplest form, a modern positive pressure ventilator, consists of a compressible air reservoir or turbine, air and oxygen supplies, a set of valves and tubes, and a disposable or reusable "patient circuit". The air reservoir is pneumatically compressed several times a minute to deliver room-air, or in most cases, an air/oxygen mixture to ...
Anesthesia breathing circuit, a system of breathing hoses which may be connected to a mask, laryngeal mask airway or tracheal tube to support the administration of anaesthesia; Anesthetic machine, a machine which may be connected to a mask, laryngeal mask airway or tracheal tube to support the administration of anaesthesia
An adjustable pressure-limiting valve (commonly abbreviated to APL valve, and also referred to as an expiratory valve, relief valve or spill valve) is a type of flow control valve used in anaesthesiology as part of a breathing system. It allows excess fresh gas flow and exhaled gases to leave the system while preventing ambient air from ...
