Quick Summary

This guide explains the process of zeroing or resetting the scale on an integrated hospital bed. It covers the preparatory steps, the procedure using the control panel, and important safety protocols. Detailed troubleshooting tips are also provided to address common issues and ensure consistent, accurate patient weight monitoring.

Key Points

Importance of Accurate Weighting: An accurate baseline weight is crucial for correct medication dosages, fluid management, and overall nutritional assessment.
Preparation is Key: To zero out the scale, the patient must be safely off the bed, while all linens and equipment intended for weighing should remain on it.
Locate the 'Zero' Function: Access the bed's control panel (often on the footboard or a remote) and find the 'Scale' or 'Zero Scale' button to initiate the process.
Follow On-Screen Prompts: Press and hold the indicated button, and wait for the display to show '0.0' and stabilize before placing the patient back on the bed.
Troubleshoot Carefully: If the scale won't zero, check for objects touching the bed and ensure it's on a level surface. For complex issues, consult the user manual or manufacturer.
Prioritize Safety: Always engage the bed's brakes when transferring a patient or operating the scale. Be mindful of cords, and understand the bed exit alarm system.

Understanding the 'Zero Out' Process for Hospital Beds

For hospital beds equipped with an integrated scale, the term "zero out" refers to the process of resetting the scale to a zero baseline before weighing a patient. This is a crucial step to ensure the weight of any equipment, linens, or other items on the bed is subtracted from the final reading, providing an accurate weight for the patient alone. Without this calibration, the weight measurement would be inflated and inaccurate, which can negatively impact critical care decisions related to medication, nutrition, and fluid balance.

Why Zeroing Out the Bed Scale is Crucial for Patient Care

Accurate weight measurement is not just a routine task; it is a fundamental aspect of patient care that directly influences treatment outcomes. In a hospital setting, patient weight is used for:

Medication Dosing: Many medications, particularly those for children or potent drugs, are dosed based on a patient's weight. An inaccurate weight could lead to under- or overdosing, with serious consequences.
Fluid Management: For patients with kidney or heart failure, monitoring weight changes helps healthcare providers track fluid retention or loss, guiding diuretic therapy and preventing complications.
Nutritional Assessment: Weight is a key indicator of a patient's nutritional status. Sudden or significant weight changes can signal a need for nutritional intervention or indicate a worsening condition.
Safe Transfer Limits: Knowing the patient's weight ensures that the bed's maximum weight capacity is not exceeded, preventing mechanical failure and ensuring patient safety.

How to Zero Out an Integrated Hospital Bed Scale

While the exact steps may vary slightly depending on the bed's manufacturer (e.g., Stryker, Hill-Rom), the general procedure for zeroing an integrated scale is straightforward:

Step-by-Step Guide

Prepare the Bed: First and most importantly, ensure the patient is safely out of the bed. This step is non-negotiable. Gather all linens, pillows, and any equipment (e.g., pads, drainage bags) that will be on the bed with the patient during the weighing process and place them on the bed.
Locate the Control Panel: Find the bed's control panel, which is often located on the footboard or a handheld remote. The scale function is typically indicated by a scale icon or a button labeled 'Scale'.
Access the Scale Menu: Press the button or navigate the on-screen menu to the scale function. Some models may require you to press an 'Enable' control first.
Initiate the Zeroing Process: Select the 'Zero Scale' option. The display will likely prompt you with a message like "TO ZERO SCALE PRESS CONTINUE" or will require you to press and hold a 'Zero' button.
Hold and Release: Press and hold the 'Zero' button as instructed. The display may show "HOLD" and then "CALC" (calculating).
Wait for Calibration: Continue holding until the display shows "0.0" and stops flashing. The system may beep to signal completion. Do not touch or lean on the bed during this process. The bed is now zeroed and ready for the patient.
Weigh the Patient: Place the patient back on the bed. Access the scale function again and select 'Weigh' to obtain the patient's accurate weight.

Troubleshooting Common Zeroing Problems

Sometimes, the scale may not zero out correctly or may provide erratic readings. Here are some solutions to common problems:

The scale won't zero: Check that nothing is touching the bed, including walls or side rails. The bed must be free-standing. Also, ensure the floor is level.
Erratic or inconsistent readings: This can occur if the bed is on an uneven surface, if there is a draft, or if connections are loose. Ensure all four casters are on the floor and the bed is level.
Scale reads "Over" or "Under": The scale's capacity may be exceeded or it is detecting a negative weight. Remove any extra weight and use the scale within its limits.
Error codes displayed: Consult the bed's user manual to understand the specific error code. Many error codes require recalibration or professional service.

A Comparison of Bed Scale Types


Feature	Integrated Bed Scale	Standalone Lift Scale
Accuracy	High accuracy, as the scale is built directly into the bed platform.	High accuracy, but requires correct operation and handling during patient transfer.
Portability	Not portable; the patient must remain in the bed for weighing.	Highly portable; can be moved between rooms to weigh multiple patients.
Ease of Use	User-friendly, with controls often integrated into the bed's panel. Zeroing is a simple push-button process.	Requires manual lifting and maneuvering, which may require two caregivers and specific training.
Patient Comfort	Weighing is less intrusive, as the patient remains in a comfortable position during the process.	The transfer process can be uncomfortable for some patients, especially those who are fragile or have mobility issues.
Cost	Typically higher initial cost, as the scale is a built-in feature of the bed.	Lower initial cost, but requires additional staff time for operation and training.

Safety Precautions for Hospital Bed Operation

Zeroing out the bed is just one part of ensuring overall safety when operating medical equipment. Follow these important guidelines:

Always Lock the Brakes: Before transferring a patient, providing care, or operating the scale, always ensure the bed's brakes are locked. Some beds have an alarm that sounds if the brakes are unlocked during certain procedures.
Manage All Cords and Tubing: Be mindful of cords and medical tubing, ensuring they are not pinched or tangled by the bed's movement.
Monitor Bed Exit Alarms: If the bed has an exit alarm, disarm it when assisting the patient in or out of bed and re-arm it once they are safely returned.
Consult the Manual: For any specific questions or complex issues, always refer to the bed's user manual or contact the manufacturer's technical support.

Frequently Asked Questions

The purpose of zeroing out a hospital bed is to calibrate the integrated scale, setting the baseline weight to zero. This ensures that only the patient's weight is measured, not the weight of the bed's linens, pillows, or other equipment.

Yes, it is critical that the patient is not in the bed during the zeroing procedure. All weight must be removed except for the items that will remain with the patient during weighing.

All common items that will be with the patient during weighing should be on the bed when zeroing the scale, including sheets, pillows, gowns, and any incontinence pads. This ensures their weight is correctly subtracted.

First, check that nothing is touching the bed, such as a wall or bedside table. Ensure the bed is on a level floor. If the issue persists, the scale may be out of calibration or have a technical problem, and you should contact technical support.

Inconsistent readings can result from a non-level surface, loose connections, or a foreign object interfering with the scale's sensors. Re-check that the bed is level and nothing is touching the frame before re-attempting.

Zeroing sets the scale to a zero starting point for a single weigh-in, while calibration is a more complex procedure that adjusts the scale's accuracy across its entire weighing range using certified test weights. For most daily use, zeroing is sufficient.

The scale should be zeroed every time a new patient is admitted or after changing any heavy equipment or linens on the bed. If using the bed for a patient over a long period, it can be beneficial to re-zero periodically to maintain accuracy.
