Blood Pressure Monitors
Blood Pressure Monitors, also known as NIBP machines (non-invasive blood pressure), are automatic extensions of the hand-held sphygmomanometers. They come in a variety of formats, some of which include multiple functions. For example, the Nellcor NPB-4000 and IVAC 4100/4200 include not only blood pressure monitoring, but also monitor such diverse functions as ECG, SpO2, Respiration rates, and temperature, all in a single unit.
The most common blood pressure monitors are the various models manufactured by the Critikon division of Johnson & Johnson, known as the "Dinamap" line of NIBP. Easily the most popular model in the blood pressure monitor field, customers may ask for a "Dinamap" thinking that it is the common name for a BPM, like asking for a Kleenex when you need a tissue. Display functions on Dinamaps include MAP (mean arterial pressure), sytolic and diastolic pressures (current), pulse rate, and length of the programmable cycle time. User-programmable high and low alarms for systolic, diastolic, MAP and pulse are included on most models; some models include a Stat mode, which automatically pressurizes cuffs and cycles measurements in an emergency or life-threatening situation. The Dinamap 8100 and 9340 series also includes inputs for oral and rectal temperature probes. Some models, such as the 1846 SXP, have internal printers which give a hard copy readout of blood pressure trends.
Blood pressure cuffs come in a variety of sizes to match all patient sizes, from infant through adult, in both reusable and disposable versions. They must be matched with the proper pneumatic hose for the cuff size.
