The Westley Croup Score calculator is designed to assess the severity of croup in clinical settings by evaluating five aspects of a patient's condition and assigning numerical scores to each. This total score helps determine the level of severity of croup and ranges from 0 to 17, with interpretations that aid in guiding treatment decisions.

The inputs for the calculator include observations of chest wall retractions, the presence and state of stridor, cyanosis, the level of consciousness, and air entry. Each parameter is evaluated by selecting one of the predefined options that denote the intensity or presence of symptoms. These options have corresponding numerical scores as outlined below:

| Parameter              | Options                      | Scores |
|------------------------|------------------------------|--------|
| Chest Wall Retractions | None                         | 0      |
|                        | Mild                         | 1      |
|                        | Moderate                     | 2      |
|                        | Severe                       | 3      |
| Stridor                | None                         | 0      |
|                        | With agitation               | 1      |
|                        | At rest                      | 2      |
| Cyanosis               | None                         | 0      |
|                        | With agitation               | 4      |
|                        | At rest                      | 5      |
| Level of Consciousness | Normal                       | 0      |
|                        | Disoriented                  | 5      |
| Air Entry              | Normal                       | 0      |
|                        | Mild decrease                | 1      |
|                        | Marked decrease              | 2      |

To compute the total score, each selected option from the input parameters is converted into its corresponding numerical value based on this table. The scores are then summed to derive an aggregate score.

The level of croup severity is interpreted from the total score using the following criterion:

- A score of 0 to 2 indicates "Mild croup".
- A score of 3 to 5 corresponds to "Moderate croup".
- A score of 6 to 11 signifies "Severe croup".
- A score of 12 or higher indicates "Impending respiratory failure".

The outcome of the computation, which consists of both the total score and its interpretation, provides a systematic approach to evaluating the clinical severity of croup, facilitating appropriate management decisions.

The Westley Croup Score is a clinical calculator used to assess the severity of croup in pediatric patients. Croup is a common respiratory condition in children that causes swelling of the larynx and trachea, leading to a characteristic "barking" cough. The Westley Croup Score helps clinicians to stratify the severity of the disease and guide treatment decisions. 

The score is calculated based on five clinical parameters: level of consciousness, cyanosis, stridor, air entry, and retractions. Each parameter is scored from 0 to 5, with higher scores indicating more severe disease. 

This calculator is specifically applicable to pediatric patients presenting with symptoms of croup. It is not suitable for use in adults or in children with other respiratory conditions. It should also not be used in children with known airway abnormalities or those who have ingested a foreign body, as these conditions can mimic the symptoms of croup but require different management strategies.
