Introduction

Welch Allyn Spot Vital Signs LXi

WARNING Do not allow a blood pressure cuff to remain on the patient more than 10 minutes when inflated above 10 mmHg. This may cause patient distress, disturb blood circulation, and contribute to injury of peripheral nerves. WARNING Do not place the cuff on any extremity that is used for intravenous infusions or any area where circulation is compromised. WARNING Excessive cuff tightness may cause venous congestion and discoloration of the limb. WARNING Wrapping the cuff too loosely (preventing proper inflation) may result in errors. WARNING Do not change the connector(s) on the blood pressure cuff tubing of this device to luer type. Luer type connectors are commonly used in intravenous infusion systems. Using the luer connectors on blood pressure cuff tubing creates the risk that the blood pressure tubing could be mistakenly connected to a patient's intravenous line, resulting in the introduction of air into the patient's circulatory system.

Introduction

Welch Allyn Spot Vital Signs LXi

Blood Pressure Cautions These cautions pertain to the Spot LXi blood pressure feature. 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 (Table 10) or Durable One-Piece Cuff Measurements (Table 11) on page 35 for sizing information. Caution The position and physiologic condition of the subject can affect a blood pressure reading.

Temperature Cautions These cautions pertain to the Spot LXi temperature feature. 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.

SpO2 Cautions These cautions pertain to the Spot LXi SpO2 feature. 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.
