Example
- ASA physical status class
- III — severe systemic disease
- Preoperative sepsis status
- None
- Functional status
- Independent
- Emergency case
- No
- Procedure type
- Intestinal
Result: Predicted risk of postoperative respiratory failure: 4.13% (linear predictor x = -3.144).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Use
- the respiratory companion to ariscat; reference categories (0) are ASA V, SIRS, independent, emergency = yes, hernia.
What you enter
- ASA physical status class
- Preoperative sepsis status
- Functional status
- Emergency case
- Procedure type
How this is calculated
- Model
- risk = 1 / (1 + e^-x); x = -1.7397 + ASA class + sepsis + functional status + emergency + procedure type. Predicts ventilation > 48 h or unplanned reintubation.
