These cautions pertain to the Spot Vital Signs LXi SpO
Caution Minimize extremity and cuff motion during blood pressure readings.
Caution If the blood pressure cuff is not at heart level, note the difference in
reading due to the hydrostatic effect. Add the value of 1.80 mmHg (.2 kPa) to the
displayed reading for every inch (2.5 cm) above heart level. Subtract the value of
1.80 mmHg (.2 kPa) from the displayed reading for every inch (2.5 cm) below
heart level.
Caution Proper blood pressure cuff size and placement is essential to the
accuracy of the blood pressure determination. See Reusable Two-Piece Cuff
Measurements or Durable One-Piece Cuff Measurements of the Directions for
Use for sizing information.
Caution The position and physiologic condition of the subject can affect a blood
pressure reading.
Caution The SureTemp Plus feature only operates with the probe well in place.
Caution Do not use alkaline batteries in the Braun ThermoScan PRO 4000.
Caution Biting the probe tip may result in damage to the probe.
Caution The pulse oximeter is calibrated to determine the percentage of
arterial oxygen saturation of functional hemoglobin. Significant levels of
dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin may
affect the accuracy of the measurement.
Caution Some sensors may not be appropriate for a particular patient. If at
least 10 seconds of perfusion pulses cannot be observed for a given sensor,
change sensor location or sensor type for perfusion to resume.
Caution Physiological conditions, medical procedures, or external agents that
may interfere with the pulse oximeter's ability to detect and display
measurements include dysfunctional hemoglobin, arterial dyes, low perfusion,
dark pigment, and externally applied coloring agents such as nail polish, dye, or
pigmented cream.
Caution When selecting a sensor, consider the patient's weight and activity
level, the adequacy of perfusion, the available sensor sites, the need for sterility,
and the anticipated duration of monitoring.
