Collection and Usage Attributes
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.
Must not be greater than 9999959.
Last 2 digits must not be greater than 59.

Queensland Hospital Admitted Patient Data Collection (QHAPDC):
There are validation checks between hours and ACHI procedure codes 1388200 Management of continuous ventilatory support less than or equal to 24 hours, 1388201 Management of continuous ventilatory support greater than 24 hours and less than 96 hours, and 1388202 Management of continuous ventilatory support greater than or equal to 96 hours.
For the purposes of calculating the duration of continuous ventilatory support, begin calculation with one of the following:
- Initiation of continuous ventilatory support. For example, for patients with endotracheal intubation and subsequent initiation of continuous ventilatory support, begin counting at the time of intubation. Patients with a tracheostomy, begin counting at the point when continuous ventilatory support is begun; or
- Admission of a ventilated patient. For those patients admitted with continuous ventilatory support, begin counting the duration at the time of the admission.

End the calculation with one of the following:
- Extubation (e.g. removal of endotracheal tube);
- Cessation of continuous ventilatory support after any period of weaning. For tracheostomy patients, the tracheal tube may not be withdrawn for days after discontinuation of continuous ventilatory support. Therefore, the duration would end with the cessation of continuous ventilatory support;
- Discharge, death of transfer of a patient on continuous ventilatory support; or
- Change of episode type.

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.

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:
- Ventilatory support was performed for respiratory support prior to surgery and then continued during surgery and post surgery; or
- Ventilatory support was initiated during surgery, continues after surgery and for more than 24 hours post surgery.

Hours of ventilatory support should be reported as completed hours and minutes.

For national reporting of the Episode of admitted patient care-duration of continuous ventilatory support, total hours data element this data element is converted to completed cumulative hours in the hhhh format. For example:
- If the total duration of continuous ventilatory support is 98 hours 45 minutes, round down to 98 hours (0098).
- If the total duration of continuous ventilatory support is equal to or greater than 99999 hours, report 9999 hours (9999).
