- Abstract
The vaporiser was then sent to the service centre.{Figure 1} The D-Vapor is a heated, calibrated anaesthetic vaporiser. Sir, Desflurane vaporisers are unique and different from others as they require an external heat source, which compensates for the significant heat loss associated with desflurane vaporisation, and they add agent directly to the gas stream.[[1]] Desflurane is heated to 39°C (degrees Celsius), which increases the vapour pressure in the sump to 1460 mmHg, thereby preventing the possibility of boiling in warm Operation theatres (OTs).[[1]] The boiling point of desflurane is 22.8°C with a low blood-gas co-efficient of 0.42.[[2]],[[3]] All vaporisers have external, graduated transparent indicators for showing the level of the agent inside them. The total capacity of vaporiser is 300 mL.[[4]] The D-Vapor vaporiser has its battery and heating apparatus.
