Angela Wood, the board’s executive director of nursing and midwifery, said they recognised that “witnessing a medical emergency or a patient who is critically unwell can be deeply upsetting”.

She said the health board was “committed to providing care with dignity, compassion, and respect “and “corridor care is not something we want for our patients”.

“At times some patients are not receiving the standard of environment or experience we would want for them, and we are absolutely committed to addressing this.

“We have been contacted directly by the author of the social media post and will be speaking with them to understand the circumstances in more detail.”
