Introduction Warnings
xviii V Series Operating Instructions
WARNING: Do not use the NIBP cuff on the arm on the side of a mastectomy, as the 
pressure increases the risk of lymphedema. For patients with a bilateral 
mastectomy, use clinical judgement to decide whether the benefit of 
the measurement outweighs the risk.
WARNING: Continuous cuff pressure due to connection tubing kinking may cause 
blood flow interference and resulting harmful injury to the patient.
WARNING: Continuous non-invasive blood pressure measurements may cause 
purpura, ischemia and neuropathy in the limb with the cuff. Inspect the 
application site regularly to ensure skin quality and inspect the 
extremity of the cuffed limb for normal color, warmth and sensitivity. If 
any abnormality occurs, move the cuff to another site or stop the blood 
pressure measurements immediately.
WARNING: Observe extreme caution when a defibrillator is used on a patient. Do 
not touch any part of patient, table, or monitor when a defibrillator is in 
use. 
WARNING: Do not use the V 12/V 21 when it is adjacent to or stacked with other 
equipment. If adjacent or stacked use is necessary, the V 12/V 21 should 
be observed to verify normal operation in the configuration in which 
they will be used.
WARNING: Use of accessories, transducers and cables other than those specified in 
the manual may result in increased Electromagnetic Emissions or 
decreased Electromagnetic Immunity of the V 12/V 21. It can also cause 
delayed recovery after the discharge of a cardiac defibrillator.
WARNING: Do not put MPSO (Multiple Portable Socket Outlets i.e. Multiple outlet 
extension cords) used with the V 12/V 21 or its accessories on the floor. 
Connect only V 12/V 21 accessories to the same MPSO as the V 12/V 21. 
Do not overload the MPSO.
WARNING: For safe installation, mount Mindray V Series patient monitoring 
equipment only to wall mounts identified with the Mindray V Series 
logo. 
WARNING: Do not use a damaged or broken unit or accessory.
WARNING: Do not use unit if enclosure is damaged. 
WARNING: Do not reuse disposable accessories. Dispose of single use items in 
accordance with hospital policy.
WARNING: Trace Gas Hazard - When using the optional CO
2
 Module, a health 
hazard exists when trace amounts of vaporized anesthetic agents are 
chronically inspired by operating room personnel. See Appendix A in 
NFPA 56A on Inhalation Anesthetics. During any procedure where such 
agents are employed, the CO
2
 Module exhaust output should be 
connected to a medical gas-scavenging system.
WARNING: CO
2
 FilterLinesĀ® should be treated as biohazardous waste and disposed 
of in accordance with local regulations for contaminated and 
biologically hazardous items.
WARNING: When using a sampling line for intubated patients with the closed 
suction system, do not place the airway adapter between the suction 
catheter and endotracheal tube. This is to ensure that the airway 
adapter does not interfere with the functioning of the suction of the 
catheter.
