Using a BFR system with automatic LOP measurement technology, that is supported by scientific, peer-reviewed, and published evidence, will ensure delivery of effective BFR therapy, leading to safe and predictable outcomes. Using BFR systems with unsupported marketing claims may negatively affect BFR safety and effectiveness and will increase the risk of financial and legal [...]
Embedded method of LOP measurement enables accurate, effective and simple prescription of personalized tourniquet cuff pressures in a clinical setting
Background Tourniquets are used to control arterial and venous blood flow in many situations, including to create a bloodless surgical field and perform blood flow restriction therapy. Advances in automatic, pneumatic tourniquet technology has improved the safety, accuracy and reliability of surgical tourniquet systems with the implementation of lower, controlled and personalized pressures with reduced [...]
Errors and Limitations Associated With Use of Pulse Oximetry to Estimate Limb Occlusion Pressure (LOP)
An interesting article by Lima-Soares et al.  was recently published in the Journal of Strength and Conditioning Research. The study compared a new method to estimate Arterial Occlusion Pressure (AOP) using visual inspection of a pulse oximeter, with an existing method using loss of sound with a handheld Doppler. The authors designed a study [...]
Recently, an interesting paper by Crossley et. al. was published in the Medicine & Science in Sports & Exercise Journal . The study investigated the relationship between blood flow and cuff pressure at rest, and during plantar flexion exercise, by measuring blood flow (Doppler Ultrasound) through the superficial femoral artery in 23 adults . Based [...]
Automatic Personalized BFR systems help the health care practitioner ensure that the best reported patient outcomes can be achieved safely and consistently. Other equipment and efforts that promise to approximate the success of automatic personalized BFR systems cannot do that, for the following 7 reasons. Reason 1: Personalized BFR tourniquet cuffs are surgical-grade tourniquet cuffs [...]
Are There Any Guidelines on Best Practices for Hospital Admission of a Patient with a Pre-Applied Tourniquet?
How should a patient be assessed and managed if a tourniquet has been applied to establish hemostasis prior to admission? What is the best practice? Do guidelines exist? The use of tourniquets in pre-hospital settings is increasing to prevent life-threatening blood loss, based on fundamental changes in doctrine regarding early use of tourniquets , and [...]
How Can Personalized Blood Flow Restriction Be Used Safely and Effectively to Accelerate Rehabilitation After Surgery?
Two significant peer-reviewed articles on Personalized Blood Flow Restriction (PBFR) were published this month in the Journal of Arthroscopic and Related Surgery. The Journal of Arthroscopic and Related Surgery is the official journal of the Arthroscopy Association of North America (AANA), and is read by many orthopaedic surgeons. The contributing authors are two well-respected and [...]
It has been well established in medical literature that the probability of tourniquet-related injuries increases as tourniquet pressure increases, and as the pressure gradient near the edges of tourniquet cuffs increase, e.g. [1-7]. Unnecessarily high tourniquet pressure gradients represent a serious and recognized hazard associated with unnecessarily high probabilities of patient injuries, specifically nerve injuries. [...]

In the recent AORN Journal article, “Back to Basics: Pneumatic Tourniquet Use” (September 2017, Vol 106, No 3), the author provided a concise summary on pneumatic tourniquets that could be used as an introduction and guideline on tourniquet safety and use. Overall, the article is very well written and provides useful information for perioperative readers. [...]
