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.
