When is a plaster bandage considered ready for use?

A plaster bandage is considered ready for use when air bubbles cease to appear. This indicates that the plaster has adequately absorbed water and is beginning to set. The formation of air bubbles typically occurs when the plaster is first mixed with water; their disappearance signals that the plaster is achieving optimal consistency and uniformity.

Achieving this phase is crucial because the absence of air bubbles contributes to the overall integrity and strength of the bandage. Using the bandage before this step can lead to weaker bonding and imperfections in the application, which can compromise the effectiveness of the plaster cast.

Other options, such as the bandage being wet, hard, or warm to the touch, do not accurately indicate its readiness for use. A wet bandage lacks the necessary consistency and can make application difficult, while heat can occur during the curing process but does not confirm that it is ready to be used effectively in a surgical context. The key marker of readiness is the absence of air bubbles, ensuring a uniform and stable application.
