What Is the M3918A Compatible NIBP Air Hose?

The IPR Medical BPH-AS25-02M-02M is a compatible aftermarket (not OEM) NIBP air hose that replaces OEM part M3918A. Made as a reusable accessory, this 8.2 ft (2.5 m) single-tube hose serves adult and pediatric patients and is paired with a 1-tube bayonet cuff.

Compatible Monitor Models

The Compatible Monitor Models table on the Specifications tab lists the equipment this hose is matched to, drawn from a wide range of manufacturers. Examples include select Zoll models (E Series, M Series, and X Series), select Contec models such as the CMS 6000 and CMS 9000, select Biolight models such as the M8000 and M9500, the Physio-Control Lifepak 15, and select Ivy Biomedical models (450C and CM5). Select Mindray / Datascope, Edan, Criticare / CSI, and Spacelabs models are represented as well, along with several other brands and the OEM’s own model numbers. Checking your exact model against that table before ordering avoids a mismatch.

Design and Construction

The BPH-AS25-02M-02M uses one tube rather than two. Its BP plug carries the Female Bayonet Recept designation, and the cuff it works with is a 1-tube bayonet type. Hose length is 8.2 ft (2.5 m), patient size is adult/pediatric, and each hose ships in its own bag. Because it is reusable, it can go back into service after cleaning per facility protocol, provided it still passes inspection.

When to Replace Your NIBP Air Hose

Typical signs of a worn hose include an audible leak at a fitting, tubing that has stiffened or cracked, cuts or abrasion along its length, and kinks that will not relax. Clinicians may also notice repeated NIBP measurement failures, cuffs that are slow to fill, or pressure that drops before a reading completes. If a known-good hose clears the problem on the same monitor and cuff, the old hose should be replaced.
