Oxygen is one of the most commonly administered therapies in hospital practice. On a busy ward, it can feel almost instinctive — the saturations drop, the patient looks breathless, and oxygen goes on. Over the years working in NHS renal and urology settings, I have seen how quickly it becomes the default response to abnormal observations, clinical concern, or even professional anxiety. It is often perceived as universally “safe”, something that can only help and never harm.

Fluids — they seem simple. Yet nothing feels basic when you are standing at a bedside, watching blood results drift upward, considering intake and output charts, or recalculating fluid balance for the third time in a shift.

Sepsis remains a leading cause of preventable mortality and critical illness worldwide. In the UK, it is estimated to contribute to tens of thousands of deaths annually, with early recognition repeatedly identified as the single most important modifiable factor influencing outcomes (NICE, 2016; UK Sepsis Trust, 2023).

Every shift, nurses ask patients to rate their pain on a scale of zero to ten. But what happens when that number doesn’t reflect how much someone is really suffering?

On a busy nursing shift, observations are often the most frequently performed assessment — and sometimes the most easily overlooked. Taken repeatedly throughout the day, they can begin to feel routine, reduced to numbers on a chart rather than meaningful clinical information.
