Table 3 Core post-intervention variables
Data variable number | Data variable name | Type of data | Data variable categories or values | Definition of data variable |
|---|---|---|---|---|
16 | Post-intervention ventilation | Nominal | 1 = Spontaneous 2 = Controlled 3 = Mixed 4 = Unknown | How is patient ventilated following airway management? If both spontaneous and controlled, choose mixed. |
12b | Post-intervention systolic blood pressure (SBP) | Continuous | Number/Not recorded | First value recorded by the EMS provider after finalised airway management |
15b | Post-intervention SpO2 | Continuous | Number/Not recorded | First value recorded by the EMS provider after finalised airway management |
17a | Post-intervention EtCO2 | Continuous | Number/Not recorded | First value recorded by the EMS provider after finalised airway management |
12c | Post-intervention SBP on arrival | Continuous | Number/Not recorded | First value recorded by the EMS provider after patient arrives at hospital |
13b | Post intervention heart rate | Continuous | Number/Not recorded | First value recorded by the EMS provider after finalised airway management |
15c | Post-intervention SpO2 on arrival | Continuous | Number/Not recorded | First value recorded by the EMS provider after patient arrives at hospital |
17b | Post-intervention EtCO2 on arrival | Continuous | Number/Not recorded | First value recorded by the EMS provider after patient arrives at hospital |
18 | Survival status | Nominal | 1 = Dead on-scene or on arrival 2 = Alive on hospital arrival 3 = Unknown | Patient survival status: EMS treatment and on arrival at hospital |
19 | Attempts at airway intervention | Nominal | 1 = One attempt 2 = Multiple attempts by one provider 3 = Multiple attempts by two or more providers 4 = Unknown | Number of attempts at securing the airway with a supraglottic airway device (SAD) or tracheal intubation (TI). |
20 | Complications | Nominal | 1 = ETT misplaced in oesophagus 2 = ETT misplaced in right mainstem bronchus 3 = Teeth trauma 4 = Vomiting and/or aspiration 5 = Hypoxia 6 = Bradycardia 7 = Hypotension 8 = Other, define 9 = None recorded | Problems and mechanical complications recognised on scene and caused by airway management. Physiologic complications (5, 6, and 7) are regarded as such if they were not present before airway intervention and were recorded during or immediately after airway management. The following definitions are used: hypoxia: SpO2 < 90% bradycardia: pulse rate <60 bpm hypotension: SBP < 90 |
21 | Drugs used to facilitate airway procedure | Nominal | 1 = Sedatives 2 = NMBA 3 = Analgesics/opioids 4 = Local/topic anaesthetic 5 = None | Drugs used to facilitate the airway intervention. Select all that apply |
22 | Intubation success | Nominal | 1 = Success on first attempt 2 = Success after more than one attempt and one rescuer 3 = Success after more than one attempt and multiple rescuers 3 = Not successful | Successful intubation defined as tube verified in the trachea. An intubation attempt is defined as attempted laryngoscopy with the intent to intubate |
23 | Device used in successful airway management | Nominal | 1 = Bag Mask Ventilation 2 = SAD 3 = Oral TI 4 = Nasal TI 5 = Surgical airway 6 = None 7 = Unknown | Device used to manage successful airway or device in place when patient is delivered at hospital/ED |
