'Robot paramedics' used to carry out CPR on patients in ambulances

‘Robot paramedics’ are being used for the first time in the UK to carry out chest compressions on patients in ambulances

  • The LUCAS 3 device is a mechanical machine that can delivery CPR
  • It uses Bluetooth to configure the compression rate, depth and alerts
  • It can also collect data which can be reviewed and shared with other clinicians
  • South Central Ambulance Charity has funded 28 of the devices to support crews across Oxfordshire, Berkshire, Buckinghamshire and Hampshire 

A ‘robot paramedic’ is being used for the first time to carry out chest compressions on patients in ambulances to free up the emergency team to carry out other vital treatments.

South Central Ambulance Service (SCAS) is the first in the country to take the new state-of-the-art technology, known as LUCAS 3, onboard its vehicles.

The device is a mechanical system which can deliver high-quality cardiopulmonary resuscitation (CPR) chest compressions consistently from the moment crews arrive on scene and throughout a patient’s journey to hospital without interruption.

CPR is essential to maintaining blood and oxygen flow around the body while a person is unconscious and not breathing.

HOW TO GIVE CPR 

CPR can be used to try to restart someone’s heart if it has stopped.

CPR should only be used in an emergency situation if someone is unconscious and not breathing. 

To carry out a chest compression:

1. Place the heel of your hand on the breastbone at the centre of the person’s chest. Place your other hand on top of your first hand and interlock your fingers.

2. Position yourself with your shoulders above your hands.

3. Using your body weight (not just your arms), press straight down by 5-6cm (2-2.5 inches) on their chest.

4. Keeping your hands on their chest, release the compression and allow the chest to return to its original position.

5. Repeat these compressions at a rate of 100 to 120 times per minute until an ambulance arrives or you become exhausted.

An SCAS spokesman said: ‘Once paramedics arrive and begin CPR or take over from bystanders who may have initiated it, the transition from manual compressions to LUCAS can be completed within seven seconds, ensuring continuity of compressions.’

The system uses wireless Bluetooth connectivity, allowing it to configure the compression rate, depth and alerts specific to an organisation’s resuscitation guidelines.

It also means it can collect data which can be reviewed post-event and shared with other clinicians.

Dr John Black, medical director at SCAS, said: ‘We know that delivering high quality and uninterrupted chest compressions in cardiac arrest is one of the major determinants of survival to hospital discharge but it can be very challenging for a number of reasons.

‘People can become fatigued when performing CPR manually which then affects the rate and quality of compressions, and patients may need to be moved from difficult locations, such as down a narrow flight of stairs, or remote places which impedes the process.

‘There are also significant safety risks to ambulance personnel being unrestrained and performing CPR in the back of vehicles travelling at high speed.

‘These devices don’t fatigue or change the delivery in any way, meaning high quality CPR can be delivered for as long as is required while freeing up the paramedic, keeping them seated and belted and able to focus on other critical aspects of patient care on a journey.

‘It ultimately acts as a robotic third crew member for our teams.’

The model used is upgraded from a version which clinicians at SCAS evaluated in 2014 as part of the PARAMEDIC trial led by the University of Warwick and published in journal The Lancet.

Professor Charles Deakin, divisional medical director for SCAS and lead for resuscitation, added: ‘The LUCAS device transforms the management at a cardiac arrest and allows paramedics to focus on the key aspects of clinical care.

 LUCAS devices are also used for resuscitation in hospital emergency departments and to support patients in cardiac arrest in intensive care units

‘It will be an invaluable part of the team and contribute to the already outstanding results that SCAS have achieved in saving lives of these patients.’

South Central Ambulance Charity has funded 28 of the devices to support crews across Oxfordshire, Berkshire, Buckinghamshire and Hampshire.

LUCAS devices are also used for resuscitation in hospital emergency departments and to support patients in cardiac arrest in intensive care units, as well for patients undergoing life-saving coronary balloon angioplasty and stenting procedures to widen narrowed arteries.
