This equipment generates, uses, and can radiate radio frequency energy. If not installed and used
in accordance with the instructions in this manual, electromagnetic interference may result. The
equipment has been tested and found to comply with the limits set forth in IEC 60601-1-2 for
medical products. These limits provide reasonable protection against electromagnetic interference
when operated in the intended use environments described in this manual.
MRI Notice
This equipment contains electronic and ferrous components whose operation can be affected
by intense electromagnetic fields. Do not operate the MAXBlend2 in an MRI environment or in
the vicinity of high-frequency surgical diathermy equipment, defibrillators, or shortwave therapy
equipment. Electromagnetic interference could disrupt the operation of the MAXBlend2.
WARNINGS
Indicates a potentially hazardous situation, if not avoided, could result in death or serious injury.
The following warnings apply any time you operate or service the MAXBlend2:
» Always confirm prescribed flow before administering to patient and monitor flow on a frequent basis.
» Always follow ANSI and CGA standards for medical gas products and flowmeters and oxygen handeling.
DO NOT operate the MAXBlend2 unless qualified personnel are in attendance to promptly
respond to alarms, inoperative conditions, or sudden malfunctions. Patients on life-support
equipment should be visually monitored at all times.
DO NOT ignore audible alarms of the MAXBlend2. Alarms indicate conditions that require your
immediate attention.
DO NOT use parts, accessories, or options that have not been authorized for use with the
MAXBlend2. Using unauthorized parts, accessories, or options may be harmful to the patient or
damage the MAXBlend2.
»
Check all audible and visual alarms periodically to ensure they are operating properly. If an alarm
fails to activate, contact your Maxtec Certified Service Technician.
DO NOT operate the MAXBlend2 with the monitor powered off or without setting the adjustable
alarms. All adjustable alarms must be set to ensure safe operation.
DO NOT steam autoclave or otherwise subject the MAXBlend2 to temperatures above 122°F (50°C).
»
If the air or oxygen gas source fails, the pressure differential alarm will sound alerting the
clinician that a condition has occurred that may significantly alter the FiO
2
and flow output from
the MAXBlend2.
»
If either the air or oxygen source pressure is reduced or increased sufficiently to create a
pressure differential of 20 PSI or more, an audible alarm will sound. This condition may
significantly alter the FiO
2
and flow output from the MAXBlend2.
DO NOT use humidified oxygen to calibrate this system. If calibrated with humidified oxygen,
subsequent oxygen readings will be higher than the true oxygen level.
DO NOT tape, obstruct or remove the alarm during clinical use.
DO NOT occlude the sensor port on the side of the MAXBlend2.
» An air inlet/water filter is recommended for use with the MAXBlend2. See section 6.1.
