Emergency Department

Bluewater Health’s emergency departments in Sarnia and Petrolia see over 86,000 patients each year. We are open 24 hours a day, seven days a week, all year long. When you or your loved one arrives at a Bluewater Health hospital you will be triaged. This helps us decide how quickly you will need care, depending on your condition.

In Sarnia, when you are triaged, you will also be assigned a ‘section’ or area in the department. This again, depends on the type of care you require. This assignment helps ED staff know how serious your condition is, and what they can expect as part of your treatment.

The three sections in the Sarnia Emergency Department are:

Green
The Green Zone is for patients who are here with illnesses that require less investigation and testing than those patients going to the yellow zone.  For example, a patient who comes in with a swollen ankle from tripping during a soccer game would most likely be seen in the Green Zone. 

Yellow
Yellow zone patients require more in-depth assessment, testing and investigations and require some type of treatment for their illness. For example, a patient who comes in with stomach pain that hasn’t been relieved by over the counter medications would most likely be seen in the Yellow Zone to rule out more serious issues. 

Red
The Red Zone is for our sickest patients.  Patients seen in this area include those with cardiac events including stroke or heart attack. Patients that have difficulty walking without an aide (cane, wheelchair, walker) are often cared for in this zone. 

In Petrolia Emergency Department you may be directed to take a seat in the waiting room or taken directly into the ED depending on the severity of your illness or injury.

Our goal is for every patient to be seen as quickly as possible.  However, sometimes wait times occur due to high patient volumes or a number of very sick patients needing intense or life-saving treatment. If you or your loved one are feeling worse than when you came in please let the nursing staff know. 

Call your primary care provider first! Your family doctor or nurse practitioner are the best care providers for non-emergencies including the common cold, an ingrown toe nail or a UTI. They know your history and medications, and are your best place for consistent healthcare. If you cannot reach your primary care provider click here for a list of alternative health care providers/resources in our community.

Narcotics – We do not renew prescriptions for narcotics or controlled substances. All narcotics should be prescribed by your primary care provider as they know you best. If you do not have a family doctor, please ask the registration clerk for information about how to find one or click here for a list of doctors currently accepting new patients.
