New & Used Anesthesia Machine

Tips for buying Anesthesia Machine

1. Buyers can purchase customized modular systems assembled from standard components or they can put together their own modular systems. 
2. Standardization of anesthesia equipment should be seriously considered. Facilities should choose systems that are compatible with the equipment already in their possesion, reduce parts inventory, minimize the number of suppliers and service personnel, and diminish confusion. 
3. A preferred unit is one that accepts compressed-air input, to allow delivery of air and N2O. 
4. It shouldn't be possible to deliver only air and N2O simultaneously. Anesthetic vapor concentration delivered to the common gas outlet should be accurate within 0.2% vapor concentration of agent, or 10% of the set value at any gas flow. 
5. It is preferable that ventilation rate and PEEP values will be monitored. 
6. The anesthesia unit should include a gas supply and control circuit, breathing and ventilation circuit, and a scavenging system. 
7. The units must be able to measure O2 concentration, airway pressure, and either the volume of expired gas or the concentration of expired CO2. 
8. Medium performance units can be upgraded to high performance units by adding stand-alone physiologic and/or gas monitors. 
9. Pre-configured monitoring offers advantages such as convenience, electronically integrated displays and prioritized alarms. 
10. If the facility already owns the monitors, it can use modular systems, which can be cheaper than preconfigured systems. 
11. Pulse oximeters provide a spectrophotometer assessment of hemoglobin oxygenation by measuring light transmitted through a capillary bed, synchronized with the pulse. 
12. Line powered units should be equipped with a power loss alarm; battery-powered units should have an automatic low-battery alarm. If line power is interrupted, the anesthesia unit should automatically switch to the internal battery.
