Continuous ventilatory support or invasive ventilation refers to the application of ventilation via an invasive artificial airway. For the purposes of this data element, invasive artificial airway is that provided via an endotracheal tube or a tracheostomy tube.
An endotracheal tube can be placed orally or nasally. It is usually employed prior to a surgically placed tracheostomy tube.
With prolonged ventilation, or when prolonged ventilation is expected, a tracheostomy tube is placed surgically.
For the purposes of calculating the duration of continuous ventilatory support, begin calculation with one of the following:
End the calculation with one of the following:
Subsequent periods of continuous ventilatory support should be added together. For example, if a patient is on continuous ventilatory support on the first day of their admission, then again on the fourth day of their admission, the hours should be added together.
If there is a period of less than 1 hour between cessation and then restarting of ventilatory support, continue counting the duration. If there is removal and immediate replacement of airway devices, continue counting the duration.
Ventilatory support which is provided to a patient during surgery is associated with anaesthesia and is considered an integral part of the surgical procedure. Duration of continuous ventilatory support should not be counted if it is part of a surgical procedure, except in the following circumstances:
Hours of ventilatory support should be reported as completed cumulative hours. For example, if the total duration of ventilatory support was 98 hours 45 minutes, report 98 hours. If a patient is intubated and ventilated for < 1 hour the intubation and ventilation are not reported. This includes patients who die or are discharged or transferred.
