Training law enforcement officers in some advanced emergency medical skill sets will, without a doubt, save lives. In a brief period of time officers can be taught how to apply a tourniquet correctly and use a clotting agent or pressure dressing to stop massive bleeding. Occlusive dressings or chest seals are easy to apply and require only minimal training. Nasopharyngeal airways can be inserted by officers with instruction by medical professionals.
The needle decompression for relieving a tension pneumothorax is also a simple procedure with minimal risks and easily taught and mastered. One of the toughest things for most people to work through is the person's initial pain reaction as you insert the needle. What the responder has to realize is that the victim has been shot, and already has one or more holes in his or her chest from a gunshot wound. That's why inserting a small needle in this person's chest wall will not harm the person especially, if he or she is short of breath, having difficulty breathing, and dying. The small bit of pain the person experiences from the needle insertion can bring great relief.
Most states have regulations covering emergency medical response by first responders. In California, Title 22 governs the medical scope of practice for lifeguards, peace officers, EMTs, and paramedics.
A recent needed revision to this California law now allows peace officers to use tourniquets and clotting agents on victims of penetrating trauma. Many patrol officers as well as law enforcement upper management in the state have taken the position that "Blue Lives Matter" and a further revision of Title 22 is needed to allow California's peace officers the ability with proper training and education to perform a needle decompression under exigent circumstances, especially on fellow officers.
The counterargument on the EMS side is that law enforcement officers can't retain these skill sets because of a lack of ongoing practice. In 2008 a medical study was conducted by Matthew D. Sztajnkrycer, MD, Ph.D. at the Mayo Clinic in Rochester, MN, to assess the ability of non-medical law enforcement personnel to learn how to decompress a tension pneumothorax and to determine long-term knowledge and skill retention.
