What is anesthesia machine?
An anesthesia machine is the apparatus used to deliver general anesthesia to patients as they undergo a medical procedure. The most commonly used device is the continuous-flow anesthetic machine, which provides a steady flow of air containing a regulated supply of gas.
What is the APL valve on the anesthesia machine?
The adjustable pressure-limiting (APL) valve is part of the anaesthesia machine breathing circuit. The APL releases anaesthetic gases into the scavenging system and is intended to provide pressure control in the breathing circuit during manual bag ventilation.
What is reservoir bag?
Reservoir bags are bladder-type bags, made of latex-free material or silicone, ranging in size from 1 L to 8 L. The 3-L reservoir bag is the most frequently used in dentistry (Fig. 14.21).
What is a CO2 absorbent?
CO2 absorbents were introduced into anesthesia practice in 1924 and are essential when using a circle system to minimize waste by reducing fresh gas flow to allow exhaled anesthetic agents to be rebreathed. As a result, CO2 absorbents have been developed that contain little or no sodium hydroxide.
How does the APL valve work?
The APL valve, also known as the pop-off valve, has two functions. It limits the maximum pressure during manual ventilation. It also exhausts excess gas into the scavenger system during manual and spontaneous ventilation. The APL valve is connected to the patient airway through the ventilator.
What is an F circuit?
The Universal F-Circuit is designed to maintain humidity and prevent heat loss. The F-circuit fits almost any anesthesia machine designed to deliver rebreathing anesthesia.
What gases are used in anesthesia machine?
The medical gases used in anaesthesia and intensive care are oxygen, nitrous oxide, medical air, entonox, carbon dioxide and heliox.
What is a rebreather bag?
A rebreather mask has a plastic reservoir bag that saves one-third of a person’s exhaled air, while the rest of the air gets out via side ports covered with a one-way valve. This allows the person to re-breath some of the carbon dioxide, which acts as a way to stimulate breathing.
Why soda lime is used in anesthesia machine?
Soda lime is a mixture of NaOH & CaO chemicals, used in granular form in closed breathing environments, such as general anaesthesia, submarines, rebreathers and recompression chambers, to remove carbon dioxide from breathing gases to prevent CO2 retention and carbon dioxide poisoning.
