How does a GE Datex Ohmeda GMS absorber work?from sciencedirect.com
The GE-Datex-Ohmeda GMS absorber uses an APL valve similar in design to that shown in Fig. 4.9A, which basically is a spring-loaded disk. When the spring is fully extended, it exerts a pressure of approximately 1 cm H 2 O on the disk to hold the valve closed. This is necessary because the waste gas scavenging interface is connected downstream of the APL valve and transfer tubing. If an active scavenging system is used—that is, if suction is applied to the interface—the negative pressure could potentially be applied to the patient circuit (see Chapter 5 ). To prevent this, the GE-Datex-Ohmeda scavenger interface uses a negative-pressure relief (“pop-in”) valve that opens at a pressure of −0.25 cm H 2 O to allow room air to enter the interface. Thus the greatest negative pressure needed to open the APL valve (−0.25 cm) is less than the least spring tension needed to keep the valve closed (∼1 cm H 2 O). This arrangement, with the use of an active scavenging system, protects against application of excess negative pressure to the breathing circuit. In the fully closed position, the maximum spring pressure applied to the GE-Datex-Ohmeda APL valve disk is 75 cm H 2 O. Thus, in the manual/bag mode, the circuit pressure in a GE-Datex-Ohmeda breathing system is limited to 75 cm H 2 O. Note that in the ventilator mode, the circuit pressure is limited by high pressure-limit settings on the GE-Datex-Ohmeda ventilator (up to 100 cm H 2 O with the GE-Datex-Ohmeda 7800 and 7900 ventilators; see Chapter 6 ).
How often should you disinfect anesthesia machines?from sciencedirect.com
Dräger’s instructions for use, citing German standards, classify the internal breathing system (including the ventilator bellows and ventilator hose) Dräger recommends high-level disinfection of these components weekly. However, Dräger qualifies with the statement that, “The instructions of the hospital’s infection control officer take precedence.” 50 In the United States, it is not common practice to disinfect the internal components of the anesthesia machine every week. Other manufacturers have not established time intervals for reprocessing internal anesthesia breathing system components; rather, a statement is made to reprocess “as necessary,” and the determination of the need for and frequency of reprocessing of any particular component is deemed the responsibility of the institution, consistent with established principles of clinical microbiology and infection control.
How long does a MK 16 UBA dive last?from sciencedirect.com
The large, well-insulated carbon dioxide–absorbent canister on the MK 16 UBA achieves operating durations of up to 300 min, depending on the depth and water temperature of the dive. 31 Because the MK 16 UBA monitors and controls the oxygen levels in the apparatus, there is no need to purge the rig before diving. The higher partial pressure of oxygen breathed by the diver at shallow depths provides a distinct advantage over air breathing during shallow dives and decompression stops. The U.S. Navy has approved the use of a computer program that allows customized computation of decompression for combination air/0.7 ata nitrox dives, and the reduction in decompression time realized by using the MK 16 instead of air at shallow decompression stops is approximately 60%. 32
When was sevoflurane first used?from sciencedirect.com
Sevoflurane was first synthesized in 1968 but development was halted in the United States because of concern about toxicity. Following further extensive development and safety testing in Japan, sevoflurane was released for clinical use in that country in 1990 and in the United States in 1995, making it the newest of the inhaled agents to be marketed ( Kronen, 2003 ). Sevoflurane is less pungent and, possibly, less aversive than isoflurane during mask or chamber induction, although neither agent causes coughing or breath-holding in rats. It is also less potent than isoflurane or halothane, and has a higher vapor pressure than either, but the precision vaporizers needed to use it are widely available and of conventional design. The low blood and tissue solubility of sevoflurane results in rapid induction and recovery, and more responsive control of anesthetic depth ( Eger, 1994 ).
What are the drugs that are used in ESRD?from sciencedirect.com
ESRD affects each opioid differently. Fentanyl, sufentanil, and hydromorphone can be safely used in patients with ESRD, but may require dose adjustments. Morphine, codeine, oxycodone, and meperidine are all medications that should be avoided in ESRD. These drugs undergo hepatic metabolism into various active metabolites that depend on renal excretion. The accumulation of these metabolites has been associated with adverse events. Morphine-6-glucoronide is an active metabolite of morphine and codeine, which accumulates causing respiratory depression. The use of oxycodone is also associated with respiratory depression in ESRD. Meperidine is unique, in that its active metabolite, normeperidine, is associated with seizures. 62
How is carbon dioxide removed from the body?from sciencedirect.com
Carbon dioxide can be continuously removed from the system by passing the gas stream through a carbon dioxide absorbent. To compensate for the patient's oxygen consumption, oxygen is added to the breathing circuit to maintain a constant volume.

Sodasorb® LF offers proven reliability, safety and performance – contributing to patient and staff well-being and peace of mind. Simply put, the days of spending your valuable time worrying about these risks will be over with Sodasorb® LF.
Why is sodasorb absorbent made of pellets?
Sodasorb absorbent is specially processed into porous, uniform pellets in order to expose the maximum absorbent surface area. The hardness of Sodasorb’s pellets gives it high resistance to powdering and breakage.
How much carbon dioxide does a canister of soda absorb?
This assumes no significant amount of channeling through the absorbent. Hence, for an eight hour capacity , a canister should hold approximately 1 kilogram of Sodasorb absorbent.
What is the wall effect in soda?
The deeper travel of the gas along the inside periphery of the canister is known as the wall effect. Pellets on the outer layer are in contact with the smooth wall, and the open space between these pellets and the wall is greater than elsewhere within the Sodasorb mass because no protuberances from other pellets are available to fill or partly fill the hollows. Hence, the flow resistance along the inside wall of the canister is less and the gas preferentially travels along this path. To avoid the wall effect, the canister should be well packed and routinely shaken prior to use to settle the Sodasorb into a consistent packing density within the cartridge or canister.
How many cc is a CO2 absorber?
With minor differences, CO2 absorbers usually consist of two transparent chambers, each with a capacity of approximately 1,000 to 1,500 cc (cubic centimeters). Each chamber, when properly packed, should contain from 950 to 1,300 grams of Sodasorb pellets and provide void space of approximately 500 to 750 cc. These figures apply to the traditional anesthesia absorber units and may not correlate to single-use disposable cartridges.
How is breathing controlled?
Breathing is regulated by neurons located in the brain stem within the lower pons and medulla. These neurons are excited by higher centers and circulating chemical factors. In particular, the rate and depth of ventilation are a function of the oxygen and carbon dioxide content of the blood. The cerebral chemosensitive area is stimulated by an increased Carbon dioxide tension and decreased pH. The control mechanism acts both directly on the respiratory center and reflexly through the chemoreceptor located in many parts of the body.
Can you use sodasorb absorbent with chloroform?
Sodasorb absorbent should not be used with trichlorethylene or chloroform A possible reaction of strong bases with halogenated compounds has been known since the early 20th century (Kemp & Vellaccio, 1980). For example, the interaction of chloroform with a strong base can produce, via a carbanion intermediate, the highly reactive chemical dichlorocarbene (CC12). This molecule can react spontaneously with water to produce phosgene and formic acid, from which carbon monoxide can be produced.
Is sodasorb an exothermic reaction?
The chemical reaction of carbon dioxide with a strong base such as Sodasorb is exothermic, the heat of neutralization approximating 13,500 calories with the absorption of each gram molecular weight of carbon dioxide (44 grams or 22.4 liters). This heat is not evenly distributed throughout the canister because the reaction itself is zonal.
How long does it take for soda lime to dry out?
When you have demonstrated 6-10 hours of active use, the soda lime needs to be changed. If you do not reach 6-10 hours of use within a week you may consider changing your soda lime anyway, as it will be slowly drying out. Remember, moisture is required for the chemical reaction in the soda lime to occur, ensuring that carbon dioxide is absorbed 6.
What does a capnogram look like when soda is exhausted?
When your soda lime is exhausted, your Capnogram will look like the image above – whereby the baseline increases from 0 to higher, the higher the baseline sits at the more exhausted your soda lime is . The shape of the capnogram would otherwise look normal 7.
How else can I tell that the soda lime is exhausted?
Fresh soda lime is easily crumbled if you crush it between your fingers (whilst wearing gloves!). Exhausted soda lime (which can absorb no more CO 2) will feel hard if handled.
How does soda lime absorb carbon dioxide?
Soda lime absorbs carbon dioxide (CO 2) through a complex chemical reaction, which also requires moisture to occur.
How to use soda lime rebreathing circuit?
How to Use: When you are using a rebreathing circuit that utilizes soda lime, simply place a cross or your initials in a triangle after every 15mins of use.
Can you crush soda lime?
Fresh soda lime is easily crumbled if you crush it between your fingers (whilst wearing gloves!). Exhausted soda lime (which can absorb no more CO 2) will feel hard if handled.
Is soda lime hard to handle?
Exhausted soda lime (which can absorb no more CO 2) will feel hard if handled. Active soda lime heats up as the chemical reaction is occurring. If you feel the canister during an anaesthetic, it should be warm. If it is not warm, it is not working!
What absorbents contain potassium hydroxide?
Sodium and potassium hydroxides in absorbents such as sodalime and barium hydroxide lime (Baralyme ®; Chemetron Medical Division, Allied Healthcare Products, St. Louis, MO), acting to abstract a labile proton from anesthetic molecules possessing certain structural features rendering them susceptible to degradation, were identified as the root cause of anesthetic breakdown and degradant formation. 25 Several manufacturers have developed new carbon dioxide absorbents with modified amounts, or omission of, the strong bases that initiate anesthetic degradation. Because proton abstraction and hence anesthetic degradation was greater with potassium versus sodium hydroxide, 25 reduction of potassium hydroxide content has been the primary focus. Thus, Drägersorb 800 Plus ®, Medisorb ®, and Spherasorb ® contain little or no potassium hydroxide (but do contain sodium hydroxide), calcium hydroxide lime (Amsorb ®; Armstrong Ltd., Coleraine, Northern Ireland, supplied by Abbott Laboratories, Abbott Park, IL) contains neither potassium nor sodium hydroxide, 26 and lithium hydroxide, long used in nonmedical devices, has also been evaluated for use in anesthesia machines. 27 Anesthetic degradation to compound A and/or CO by these newer absorbents has been evaluated in labora-tory 26,28,29 and clinical 27,30,31 investigations. During sevoflurane anesthesia, inspired compound A concentrations with Drägersorb 800 Plus ® (Dräger Medical, Telford, PA), Medisorb ® (Datex Ohmeda, Helsinki, Finland), and Spherasorb ® (Intersurgical, Wokingham, Berkshire, United Kingdom) were approximately half those with sodalime, whereas Amsorb ® and lithium hydroxide caused little or no compound A formation. 27,30,31 Although compound A formation is of some interest and clinical studies have focused on sevoflurane, CO formation clearly constitutes a greater potential risk. Nevertheless, only limited data are available on anesthetic degradation to CO by newer absorbents, mostly from in vitro studies. This is due, in part, to ethical concerns that prevent the clinical evaluation of CO formation. In vitro studies usually do not incorporate carbon dioxide (CO 2) effects and cannot assess the pathologic consequence of CO production ( i.e. , formation of COHb).
Who provided sodalime?
The authors thank Jeff Mack (WR Grace, Atlanta, GA) for providing the sodalime and for information on its content.
Does amsorb cause anesthetic degradation?
Amsorb caused minimal if any CO formation, minimal compound A formation regardless of absorbent hydration, and the least amount of sevoflurane degradation. An absorbent like Amsorb, which does not contain strong base or cause anesthetic degradation and formation of toxic products, may have benefit with respect to patient safety, inhalation induction, and anesthetic consumption (cost).
Does Amsorb cause CO?
In summary, in comparison with sodalime and Baralyme ®, Amsorb ® caused minimal if any CO formation , minimal compound A formation, and the least amount of sevoflurane degradation. These findings seem relevant to patient safety.
