Paediatric shock (circulatory failure)
What is paediatric shock?
Shock in first aid terms means failure of the circulatory system to deliver enough oxygenated blood to vital organs; in children it can develop after severe bleeding, fluid loss, sepsis, heart problems or major trauma. Early signs may be subtle, but failure to spot and treat shock quickly can lead to collapse and cardiac arrest.
In paediatrics, shock often shows first as fast breathing and heart rate, cold or mottled skin and reduced urine output, while blood pressure may stay normal until the child is already critically unwell. Because low blood pressure is such a late and dangerous sign, first aiders must act on these earlier features and escalate rapidly so fluid resuscitation and treatment of the underlying cause can begin without delay.
National sepsis safety alerts for children highlight signs such as very fast breathing, abnormally cold skin, mottled or blue colour and extreme lethargy as triggers for urgent 999 calls, recognising that untreated sepsis and shock remain important causes of avoidable harm and death in childhood.
Who needs this skill?
Health & Social Care
In health and social care, staff may be caring for children who are septic, post-operative, dehydrated or bleeding internally; early recognition of shock and prompt escalation to clinicians is critical and scrutinised in incident reviews. Training should tie observable signs to existing early warning tools and escalation policies.Licensed venues & nightlife
Licensed venues hosting events or activities can see injuries from falls, assaults or crowd crush; staff need to recognise that cold, clammy, pale or grey-looking children with fast pulse and altered response are not just 'in shock' emotionally, but may be in true circulatory shock needing emergency care.Schools
Schools and early years providers may encounter shock from allergic reactions, severe asthma, sepsis, diabetic emergencies or injury; staff should understand that persistent pallor, drowsiness, fast pulse and cold extremities in a sick child are red flags that justify 999 rather than watchful waiting.Workplaces
In workplaces and community venues, first aiders may see shock after falls, sports injuries, burns or major bleeding; they must control bleeding, lay the child flat, keep them warm and call 999 without delay rather than sitting them up for comfort or sending them home.How to manage paediatric shock
- 1Recognise early signs of shockLook for pale, grey or mottled skin, cold hands and feet, fast pulse, fast breathing, delayed capillary refill and changes in behaviour such as irritability, confusion or unusual sleepiness. These signs together are more concerning than any one alone and should make you think 'possible shock'.The paediatric first aid syllabus expects learners to identify shock from these observable signs rather than from blood pressure readings, which first aiders will not usually have.
- 2Lay the child flat and keep them warmIf you suspect shock and there is no obvious breathing difficulty, lay the child flat and consider raising their legs slightly to help blood flow to vital organs; for infants this may mean lying them flat on a firm surface. Cover with a blanket or coat to keep warm, but avoid overheating if they are febrile.Positioning and warmth are simple but important parts of shock management; sitting up or allowing a child to walk around can worsen collapse by reducing blood flow to the brain and heart.
- 3Treat obvious causes such as external bleedingIf there is visible external bleeding, apply direct pressure with a dressing or your gloved hand, use bandages to maintain pressure and consider tourniquets or wound packing if you are trained and equipped. Continue to monitor for signs of shock even once bleeding appears controlled.Qualsafe includes optional catastrophic bleeding training with tourniquets and haemostatic dressings; when taught, this should be integrated with shock recognition so learners understand why bleeding control is so time-critical.
- 4Call 999 and prepare for deteriorationShock in children is always a medical emergency; call 999 as soon as you suspect it and state clearly that you are worried about shock in a child. Stay with the child, keep them flat and warm, reassess airway and breathing regularly and be ready to start CPR if they become unresponsive and stop breathing normally.Clear, early 999 activation is defensible and aligns with the objective of paediatric qualifications, which is to prepare learners to deal with serious first aid situations, not to manage them alone.
- 5Monitor, document and hand overNote what you saw, what you think caused the shock, what treatment you gave and how the child responded over time. Share this information with ambulance crews or clinicians and document according to organisational procedures.A good handover supports clinical decisions and provides evidence of timely, reasonable first aid if the incident later faces legal or regulatory scrutiny.

Raising the legs slightly can help circulation in many cases, but if you suspect serious chest injury, breathing problems or spinal injury you may need to adapt. The priority is a position that supports breathing while keeping the child as flat and still as is safe; follow your training and local protocols.
