An irregular heart beat (arrhythmia) causes beat-to-beat blood pressure variations and may therefore disturb
the NIBP measurement, which may fail or be inaccurate. It is advisable to confirm automatic NIBP
measurements periodically for patients with frequent premature beats or a very irregular heart rate, for example
caused by atrial fibrillation.
NIBP measurements may be inaccurate or fail in the presence of excessive movement, shivering, or trembling.
Advise patients to relax and avoid moving when a blood pressure measurement is made.
NIBP cuffs and hoses supplied with the Surveyor do NOT contain any Latex. If the patient develops an allergic
reaction or rashes, immediately remove the cuff.
Invasive Pressure Warnings
All invasive procedures involve risks to the patient. Use aseptic technique. Follow catheter manufacturer's
instructions and established hospital guidelines.
Ensure that no part of the patient connections touches any electrically conductive material including earth.
Only use invasive pressures transducers that can withstand defibrillation as required by ANSI/AAMI BP22
standard.
Mechanical shock to the invasive blood pressure transducer may cause severe shifts in zero balance and
calibration, and cause erroneous readings.
CO2 Warnings
Always inspect the airway adapter for a tight connection and proper operation before attaching it to the patient.
Remove the airway sampling line from the patient’s airway while nebulized medications are being delivered.
Route all tubing away from the patient’s throat to avoid strangulation.
Do not apply pressurized air to any outlet or tubing connected to the monitor. Pressure may destroy sensitive
elements.
When monitoring an anesthetized patient in an operating room environment, it is recommended to connect the
CO2 exhaust port of the Surveyor to the hospital’s waste gas scavenging system so as to prevent exposure for
other patients and hospital personnel to the patient’s respiratory sample. Ensure that sampled gases are not
returned from the exhaust port to a breathing system such as a ventilator. Use standard clinical guidelines and/or
hospital procedures. Scavenge vacuum greater than 1mmHg may result in damage to the Surveyor.
When using a sampling line for intubated patients with a 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 catheter.
Loose or damaged connections may compromise ventilation or cause an inaccurate measurement of respiratory
gases. Securely connect all components and check connections for leaks according to standard clinical
procedures.
Do not cut or remove any part of the sample line. Cutting the sample line could lead to erroneous readings.
If too much moisture enters the sampling line (i.e., from ambient humidity or breathing of unusually humid air),
the message CO2 Purging Line will appear in the message area. If the sampling line cannot be cleared, the
message CO2 occluded line will appear in the message area. Replace the sampling line once the CO2 occluded
line message appears.
