Brief summary
Foreign body airway obstruction (FBAO, choking) is a life-threatening emergency requiring time-sensitive treatment to prevent severe injury or deaths. Traditional treatments taught in first aid courses include abdominal thrusts, back blows, and chest compressions or thrusts. Currently, first aid guidelines recommend different treatments for adults, child and infants. Until recently, data on these techniques was limited to case series from the late 1900's. To further improve our knowledge of which treatment is most effective and safest for patients, this study will collect data on choking incidents in Alberta, Canada. The first phase of this project will make sure identifying and recruiting choking patients in real-time is possible so that the highest quality of data can be collected. If successful, this study will support a future project where the different choking treatments are compared in terms of their effectiveness and safety. This study will focus on adults and children over the age of 2 years.

Inclusion criteria
* Adult or children (aged greater than 2 years) who experienced an out-of-hospital FBAO in Alberta, Canada * Received a FBAO intervention while conscious by bystander or healthcare provider * Were assessed by EMS at the time of the incident, or later attended an emergency department due to the incident

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Eligible patient recruitment | Through study completion, a 6 month period | Count of eligible patients recruited per month |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of eligible patients recruited | Through study completion, a 6 month period | Among patients who screen as eligible for recruitment, the proportion of those who are successfully recruited |
| Proportion of recruited patients with satisfactory data collection | Through study completion, a 6 month period | Among patients successfully recruited, the those patients with \>= 90% of desired variables collected |
| Foreign body airway obstruction relief | Day 1 | Defined as: responders determining that the patient did not require further FBAO intervention due to improvement or resolution of their respiratory distress in a conscious patient, or the ability for a responder to successfully ventilate an unconscious patient when previously they were unable to due to obstruction |
| Survival to acute care discharge | From date of enrolment until the date of acute care discharge or date of death from any cause, whichever came first, assessed up to 3 month | Defined as discharge from the care of Emergency Medical Services(EMS) or paramedics, the emergency department, or the hospital. |
| Survival to acute care discharge with favourable neurological outcome | From date of enrolment until the date of acute care discharge or date of death from any cause, whichever came first, assessed up to 3 month | Defined as the patient being able to be discharge to the home environment that they previously lived, with the ability to perform the same activities of daily living as before the FBAO incident |
| Intervention-associated injuries | From date of enrolment until the date of acute care discharge or date of death from any cause, whichever came first, assessed up to 3 month | Listed summary of any injuries reported among patient recruited for study occurring as a result of the FBAO intervention as determined by the treating physician/care provider |
