Read the full statement (221 words)

The VSM 6000 Series of monitors is intended to be used by clinicians and medically qualified personnel for monitoring of neonatal, pediatric, and adult patients for:

- noninvasive blood pressure,

- pulse rate,

- noninvasive functional oxygen saturation of arteriolar hemoglobin (SpO2), and

- body temperature in normal and axillary modes.

The most likely locations for patients to be monitored are general medical and surgical floors, general hospital, and alternate care environments.

The optional Masimo Rainbow SET® and accessories are indicated for the continuous noninvasive monitoring of total hemoglobin concentration of adult, pediatric, and neonatal patients during both motion and no motion conditions, and for patients who are well or poorly perfused in hospitals and hospital-type facilities.

Optional compatible weight scales (eg., Health o meter®) can be used for height, weight, and BMI input.

The Welch Allyn Connex® Vital Signs Monitor (CVSM) 6000 Series also contains the Welch Allyn Applications Framework ("Framework"), The Framework is general purpose software that allows medical device and non-medical device software applications to be run on the CVSM independently of, and isolated from, the CVSM's vital signs monitoring functionality. All such applications are intended to be used on the CVSM by trained professionals in a health care setting.

This product is available for sale only upon the order of a physician or licensed health care professional.

Indications for use as stated in the FDA summary.
