Evaluation: Physio-Control TrueCPR CPR Feedback Device
January 8, 2016 | Evaluations & Guidance
Preview
- TrueCPR is a stand-alone device most likely to be used as an accessory to a defibrillator. It consists of a chest sensor ("puck") that is placed on the patient's sternum and a back sensor that is placed behind the patient's shoulder or under the patient's side (either side is acceptable). The chest sensor and back sensor are connected by a thick cable about 2 feet long.
- Depending on geographic location, TrueCPR provides real-time feedback to CPR providers on four of five key CPR parameters (as specified in AHA guidelines):
- Compression depth
- Compression rate
- Inactivity time
- Chest wall recoil (feedback on this parameter is only available outside the United States, United Kingdom, France, and Germany)
- The fifth parameter is ventilation; while TrueCPR provides auditory and visual prompts for ventilation, it does not monitor it or offer feedback.
- TrueCPR is intended for clinical use, but can also be used for CPR training on manikins.
- TrueCPR also provides CPR data for postevent review.
- A summary of the CPR event can be displayed directly on the device screen.
- CPR data can be downloaded; a report of CPR performance can be generated.
- Components and capabilities:
- Feedback on compressions is provided through use of a chest sensor and a back sensor.
- The chest sensor uses a proprietary system called Triaxial Field Induction (TFI), which relies on electromagnetism and a force gauge to measure compression depth and chest wall recoil, as well as to calculate compression rate.
- The chest sensor measures 7.75 × 3.25 × 1.375 in (H × W × D), and the back sensor measures 10.25 × 4 × 3 in. Both show diagrams of their proper placement.
- A display on the chest sensor indicates compression depth with a gauge, the numerical compression rate, and an event timer.
- TrueCPR does not connect to a defibrillator. It is a stand-alone device powered by nonrechargeable DL123 batteries.
- Feedback on compressions is provided through use of a chest sensor and a back sensor.
- Use limitations (per the manufacturer's instructions for use):
- TrueCPR is indicated for use on adult and pediatric patients age 8 and over.
- TrueCPR should not be used on large metal surfaces (such as the deck of a ship) or in environments with electromagnetic interference.
- TrueCPR should not be used in the presence of flammable gases or anesthetics.
- Unlike accelerometer-based systems, TrueCPR may be used in a moving environment, such as an ambulance.
