Read the full statement (461 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' Pulse CO-Oximeter and accessories are indicated for the continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (5p02). pulse rate, total hemoglobin concentration (SpHb), and/or respiration rate (RRa). The Masimno Rainbow SET' Radical 711 Pulse CO-Oximeler and accessories are indicated for use with 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.

The optional Oridion module and accessories are intended for the continuous non invasive measurement and monitoring of carbon dioxide concentration of the expired and inspired breath and respiration rate. It is intended for use with neonatal, pediatric and adult patients in hospitals and hospital type facilities.

The optional Oridion module also provides the clinician with an integrated pulmonary index (IPI). The IN is based on four parameters provided by the monitor: end tidal carbon dioxide, respiration rate, oxygen saturation and pulse rate. The IPI is a single index of an adult or pediatric patient's ventilatory status displayed on a scale of I - 10, where t0 indicates optimal pulmonary status. IPI monitoring displays a single value that represents the patient's pulmonary parameters and alerts clinicians to changes in the patient's pulmonary status.

The IN' is an adjunct to, and is not intended to replace, vital sign monitoring.

Optional compatible weight scales (e.g.. Health o meter 0 ) can be used for height, weight, and DM3 input.

The Welch Allyn Connex* Vital Signs Monitor (CVSM) 6000 Series also contains the Welch Allyn Applications Framework ("Framework"). The Fmamework 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.

The EarlySense (Everon) module is intended ror continuous measurement of respiration rate, heart rate and movement, inan automatic contact-less manner, in a hospital or clinic setting. The system is indicated for use in children, adolescents and adults. The operation oF the EarlySense has been studied inchildren (weight ? 10 Kg) and adults (weight <1I I Kg) during sleep and resting condition.

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