The bedridden patient height calculator is designed to estimate the height of patient who cannot get out of bed due to illness, injury, or other medical conditions.
The calculator uses specific body measurements that can be taken while the patient is lying down. These measurements are then input into a formula to estimate the patient’s standing height.
For example, a nurse might measure a patient’s knee height and forearm length to calculate their approximate standing height.
Bedridden Patient Height Calculator
| Gender | Age | Knee Height (cm) | Calculated Height (cm) | Calculated Height (in) | Conversion Equation |
|---|---|---|---|---|---|
| Male | 45 | 55 | 176.39 | 69.44 | in = cm / 2.54 |
| Female | 70 | 48 | 159.50 | 62.80 | in = cm / 2.54 |
| Male | 60 | 52 | 170.27 | 67.04 | in = cm / 2.54 |
| Female | 35 | 51 | 173.59 | 68.34 | in = cm / 2.54 |
| Male | 80 | 50 | 166.19 | 65.43 | in = cm / 2.54 |
Note: For males, we used the formula: Height (cm) = 64.19 + (2.04 x knee height in cm)
For females, we used: Height (cm) = 84.88 + (1.83 x knee height in cm) – (0.24 x age in years)
Bedridden Patient Height Formula
Commonly used formula is the Chumlea formula, which uses knee height as the primary measurement.
For adult men:
Height (cm) = 64.19 + (2.04 x knee height in cm)
For adult women:
Height (cm) = 84.88 + (1.83 x knee height in cm) - (0.24 x age in years)
For example, consider a 60-year-old bedridden woman with a knee height of 50 cm:
Height = 84.88 + (1.83 x 50) - (0.24 x 60)
= 84.88 + 91.5 - 14.4
= 161.98 cm
This formula estimates her standing height to be approximately 162 cm.
How do you estimate height for bedridden patients?
Estimating height for bedridden patients involves several steps:
Choose the appropriate measurement: Depending on the patient’s condition, you may use knee height, forearm length, or a combination of measurements.
Gather necessary equipment: You’ll need a flexible measuring tape or a specialized knee-height caliper.
Position the patient: Ensure the patient is lying flat on their back with their left knee bent at a 90-degree angle.
Take measurements: For knee height: Measure from the heel to the anterior surface of the thigh, parallel to the long axis of the tibia. For forearm length: Measure from the tip of the olecranon process to the tip of the styloid process.
Apply the formula: Use the appropriate formula based on the patient’s gender and age.
Consider adjustments: Some formulas include adjustments for factors like age or ethnicity.
Document and communicate: Record the estimated height in the patient’s chart and communicate it to the healthcare team.
