Understanding What "Zeroing" Means
When you need to zero out a hospital bed, you're likely performing one of two distinct functions: zeroing the scale for an accurate weight measurement or resetting the bed's frame to a flat, neutral position. Both are critical for different aspects of patient safety and care, and the process varies depending on the bed's manufacturer and model.
Zeroing the Bed's Integrated Weight Scale
For beds with a built-in scale, zeroing is the calibration process that sets the current weight to zero. This must be done to get an accurate reading of the patient's weight, as it accounts for the weight of the linens, pillows, and any attached equipment. Here's a general procedure for most modern beds:
- Prepare the Bed: Remove the patient from the bed. Ensure all standard equipment and linens that will remain with the patient (e.g., pillow, one sheet, one incontinence pad) are in place. Remove anything else, like IV bags or food trays.
- Enable Controls: Locate the control panel, often at the foot of the bed or on the side rail. Many newer beds require you to press an 'Enable' or 'Key' button first to activate the scale functions.
- Press the 'Zero' Button: Once enabled, press and hold the 'Zero' button. The display may flash, show 'Calc,' or beep. Wait for the display to show 0.0 before releasing the button.
- Place the Patient: Gently return the patient to the center of the bed. After the patient is settled and still, press the 'Weigh' button to obtain an accurate weight measurement.
Resetting the Bed to a Flat (Zero) Position
If the bed is angled or stuck in a position and you need to return it to a flat state, you're performing a bed reset, which is sometimes colloquially called zeroing. This is crucial for certain procedures, such as CPR, or for simply normalizing the bed position.
- Emergency CPR Reset: Most electric beds have a dedicated 'CPR Release' or 'Flat' button, often colored yellow or red. Pressing this button will quickly flatten the bed's surface. On some models, this feature is mechanical, involving a lever on either side of the bed.
- Remote/Handset Reset: Many beds can be returned to a flat position by pressing and holding a dedicated button on the remote or control panel. Some models, like the M9 Stretcher, may require simultaneously pressing the 'deck up' and 'deck down' buttons.
- Power Reset: If the bed is unresponsive, try unplugging it from the wall, waiting for 30 seconds to a minute, and plugging it back in. This can clear control errors and force the bed to reset.
A Comparative Look: Different Bed Models
Different bed manufacturers have slightly different procedures. Below is a comparison of common steps for zeroing the scale.
| Feature | Hill-Rom VersaCare Bed | Arjo Total Lift Bed | Multicare Bed | Invacare Homecare Bed |
|---|---|---|---|---|
| Activation | Press the 'Key' button | Turn on the scale using the power button | Press the scale icon on the LCD screen | Control pendant attached to the rail |
| Zeroing Action | Press and hold 'Zero' until display shows 0.0 | Hold 'Total Weight' for 3 seconds | Hold 'Zero' until it beeps twice | No scale; controls on pendant |
| Preparation | Patient out, standard items on | Raise bed off castors first | Patient out, standard items on | Standard operation for adjustments |
Troubleshooting Common Zeroing Issues
- Bed won't reset or flatten: Check for obstructions under the bed or between the rails and the mattress. Ensure the bed is plugged directly into a working wall outlet, not an extension cord.
- Inaccurate weight readings: Confirm the bed was zeroed with all necessary linens and equipment in place but without the patient. Any weight added after zeroing, like an IV bag, will affect the reading unless the calibration is adjusted.
- Controls are unresponsive: The remote may be faulty or the cable may be loose. Try unplugging and re-seating the remote cable. Check for battery issues in wireless controls.
Safety First: Essential Tips for Zeroing
- Read the Manual: Always consult the specific manufacturer's instructions for your bed model. Procedures can vary significantly.
- Clear the Area: Ensure there are no objects or tubing that could be pinched or caught by the bed's moving parts during a reset.
- Lock the Wheels: Lock the bed's casters before any patient transfers or position changes to prevent movement.
- Monitor the Patient: Keep the patient informed of any bed adjustments. For weighing, ensure the patient is lying still in the center of the bed for an accurate reading.
- Inspect Electrical Components: Before use, check all cords and plugs for damage. Never use a bed with a damaged power cord.
Conclusion: Ensuring Patient Safety and Accurate Data
Mastering how to zero out a hospital bed is a fundamental skill for caregivers, whether in a professional medical setting or at home. By following the correct steps for calibrating the scale and resetting the bed position, you ensure patient safety and gather accurate data crucial for effective care. Always prioritize safety and refer to the bed's manual for model-specific guidance. You can find more comprehensive resources on bed safety from authoritative sources, such as the FDA's guide on bed safety. Consistent and safe operation is key to providing high-quality care.
