Table 2. Cross-sectional survey results from different practice settings where our investigators have worked recently.

Some permanent grey cables have only three cables. Also, some permanent grey cables have five cables, but the anesthesia technician was instructed to tape away two of them to discourage use. Disposable pink cables could be cleaned and reused but always contain five cables.

Number (N) is approximate given that some locations are non-operating rooms.
