In the event of a chemical eye injury, the EMR should ensure the patient does what?

In the case of a chemical eye injury, it is crucial for the patient to hold the eye open while flushing to ensure that the affected eye is thoroughly irrigated with water or saline. This action allows for optimal removal of the harmful chemical substance from the eye surface, which can help prevent further damage to the tissues and reduce the risk of complications, such as vision loss.

Holding the eye open during the flushing process enables a steady and continuous flow of the rinsing solution, ensuring that the entire surface of the eye, including the cornea and conjunctiva, has the opportunity to be cleansed effectively. The saline or clean water should be poured gently into the eye, allowing gravity to assist in flushing away the irritant.

It's important to note that rubbing or wiping the eye could exacerbate irritation or cause scratches on the cornea, potentially worsening the injury. Attempting to apply pressure on the eye could lead to additional trauma and should be avoided. Similarly, while it may seem logical to raise the eyelid to facilitate flushing, holding the eye open provides better access for the irrigating solution without adding any unnecessary manipulation that could cause harm.
