Introduction Warnings
xx V Series Operating Instructions
WARNING: In certain situations in which perfusion and signal strength are low, 
such as in patients with thick or pigmented skin, inaccurately low SpO
2
 
readings will result. Verification of oxygenation should be made, 
especially in pre-term infants and patients with chronic lung disease, 
before instituting any therapy or intervention.
WARNING: Many patients suffer from poor peripheral perfusion due to 
hypothermia, hypovolemia, severe vasoconstriction, reduced cardiac 
output, etc. These symptoms may cause a loss in vital sign readings.
WARNING: The user will be responsible for ensuring the compatibility between the 
SpO
2
 sensor, the extension cable and other equipment by either 
referring to the instructions for using this sensor or contacting Mindray 
before use.
WARNING: SpO
2
 sensors, SpO
2
 accessories, and temperature probes should be 
disposed of in accordance with local regulations. 
WARNING: Inaccurate SpO
2
 measurements may be caused by excessive patient 
movement. 
WARNING: When monitoring patients that are not continuously attended by a 
clinical operator, properly configure the alarm system and adjust alarm 
settings as per the patient's condition.
WARNING: Bispectral Index (BIS) is intended for use only as an adjunct to clinical 
judgment and training.
WARNING: The clinical utility, risk/benefit and application of the BIS component 
have not undergone full evaluation in the pediatric population.
WARNING: The BIS component used on the V 12/V 21 is purchased from Covidien. 
It is important to recognize this index is derived using solely that 
company's proprietary technology. Therefore, it is recommended that 
clinicians have reviewed applicable information on its utility and/or 
risks in published articles and literature/web site information from 
Covidien or contact that company itself at www.covidien.com, if you 
have clinical-based BIS questions relating to this module portion of the 
patient monitor. Failure to do so could potentially result in the incorrect 
administration of anesthetic agents and/or other potential 
complications of anesthesia or sedation. 
WARNING: Clinicians are also recommended to maintain current knowledge of 
FDA or other federal-based regulatory, practice or research information 
on BIS and related topics.
WARNING: The conductive parts of the BIS sensors and connectors should not 
come into contact with other conductive parts, including earth ground.
WARNING: To reduce the hazard of burns in the high-frequency surgical neutral 
electrode connection, the BIS sensor should not be located between 
the surgical site and the electro-surgical unit return electrode.
WARNING: The BIS sensor must not be located between defibrillator pads when a 
defibrillator is used on a patient connected to the patient monitor.
WARNING: To reduce the hazard of burns during use of brain-stimulating devices 
(e.g. transcranial electrical motor evoked potential), place stimulating 
electrodes as far as possible from the BIS sensor and ensure that the 
sensor is placed according to package instructions.
