THE AMBULANCE SIREN CAN BE HEARD A BLOCK AWAY… IT HALTS AT A BUSY INTERSECTION, WAITING FOR THE CARS TO CLEAR THE PATH… SECONDS PASS QUICKLY…5…6…7…
11 SECONDS DISAPPEAR. THEY FINALLY GAIN ACCESS TO THE INJURED DRIVERS. THE DRIVER OF THE FIRST VEHICLE IS IN EXTREME PAIN WITH JVD AND TRACHEAL DEVIATION. AN ASSESSMENT REVEALS A TENSION PNEUMOTHORAX (PTX)…
THE PARAMEDIC REACHES FOR THE NECESSARY EQUIPMENT TO PERFORM A DECOMPRESSION OF A PTX. HE HAS TO OPEN THE INDIVIDUALLY PACKAGED 14 GAUGE NEEDLE, GET HIS SCISSORS, FIND A SURGICAL GLOVE, CUT A FINGER OF THE GLOVE OFF… 12… 13… 14… 15…
FIND THE TAPE, RIP THE TAPE, and TAPE THE GLOVE ONTO THE HUB … 16… 17… 18… 19… IS IT TOO LATE… DID THEY RUN OUT OF TIME?
THIS PROCEDURE TAKES ONE TO TWO MINUTES DUE TO THE RUDIMENTARY PROCEDURES CURRENTLY USED TO PERFORM A PTX DECOMPRESSION.
SAVE THE PATIENT’S LIFE… TREAT THE PATIENT’S OTHER INJURIES… MOVE ON TO HELP OTHER INJURED PEOPLE AT THE SCENE…
WHAT COULD THE PARAMEDIC DO WITH 19 SECONDS?
Combat Related Pneumothorax 5% of all combat related deaths
are related to a Tension Pneumothorax
Civilian Related Pneumothorax10 - 30% of patients transported to level 1 trauma centers receive treatment for a Tension Pneumothorax

31% - Penetrating head trauma25% - Surgically uncorrectable
torso trauma 7% - Mutilating blast trauma 9% - Exsanguination 5% - Tension pneumothorax
(PTX) 1% - Airway obstruction / injury
Saving a Life
It is estimated that 90% of wounded combatants can be saved

(C) Once unrolled, the ROFV is free and remains limp until pressurized air flows outwardly from the pleural cavity. In this manner air may pass from the patient’s pleural cavity while precluding the passage of air back into such pleural cavity.
(A) The needle and catheter are inserted into the patient’s chest.
The L-PRV concept:Patent #: 8,257,339
(B) After the needle and catheter are inserted into the patient’s chest, the needle is withdrawn. The catheter remains inside the patient’s chest while the hub and Roll-Out-Flutter Valve (ROFV) remain outside of the body.
