P.R.I.M.E.D. Prehospital Resuscitation using an IMpedance valve and Early vs. Delayed analysis trial

P.R.I.M.E.D ITD ANALYZE EARLY VS. LATE

Impedance Threshold Device

ITD - What is it? Hemodynamic adjunct (not ventilatory adjunct) Used with BVM ETT Genesis II (Manual setting only)

Compression Increased intrathoracic pressure Compression of heart and lungs Understanding the ITD Decompression (recoil) Decreased intrathoracic pressure Refilling of heart and lungs  Complete chest recoil is critical!

ITD - What are we asking you to do?

Using the ITD with a Mask or ETT Ventilate using timing lights (10/minute) Mask = ventilate at 2 : 30

ITD Timing Lights Flash 10 times per minute = 10 breaths/min. (q 6 seconds) May be used to guide compression rate. (10 compressions / breath) Use timing lights when ETT established

If Ventilation Timing Lights Fail The ITD functions independent of timeing lights Turn off the lights and ventilate patient at proper rate (10 breaths/min).

Important Reminders Mask – Continuous & tight seal Connect ITD as soon as possible – start with mask then transfer to ETT Don’t hyperventilate (timing lights 10/min) Continue to use ITD if gasping or agonal breathing (in absence of a pulse).

Remove ITD immediately if: Chest does not rise. Device fills with fluid. Device breaks or does not function properly. Patient gets a pulse (ROSC).

Important reminders… Re-apply ITD immediately if patient re-arrests Do not open a second study kit The ITD is for single-patient use only No medication through ITD (impede function) All trials are PREHOSPITAL and end on arrival to the ED.

Analyze Early vs. Analyze Late

What is it?

Randomized to Either: …then analyze rhythm 30+ sec. of CPR Analyze EARLY …then analyze rhythm 3 minutes of CPR Analyze LATER

Why are we doing this?

What are we asking of you?

Analyze Early

Analyze Late DO NOT interrupt CPR to perform ALS procedures

Remember… Bystander CPR does not count, you must still do CPR per study protocol Analyze early or analyze late assignment will be determined by the first arriving vehicle

Randomization Device level: Each defibrillator is assigned (centrally by serial number) to either Early or Later Analysis Via: Dog Tags Switching: At ~ 9 months the devices will be re-randomized

Indications (both protocols) Patients ≥ 18 years of age Non-traumatic out of hospital cardiac arrest Non-traumatic out of hospital cardiac arrest Patients ≥ 18 years of age Non-traumatic out of hospital cardiac arrest Non-traumatic out of hospital cardiac arrest

Contraindications (both protocols) Pre-existing DNR order. × Pre-existing DNR order. × Known pregnancy. × Known prisoner × Known prisoner. Pre-existing DNR order. × Pre-existing DNR order. × Known pregnancy. × Known prisoner × Known prisoner.

Contraindications: Analyze Early or Analyze Later × EMS-witnessed arrest (shock immediately) × AED / defibrillator pads attached prior to your arrival by: × Non-ROC responders - EMS or fire services OR × PAD, law enforcement, layperson OR × Off duty medic or fire fighter, medical professional, etc. Consider enrolling ITD only

Contraindications: ITD × Tracheostomy × Mechanical CPR × Patient with a pulse

Study Kits Inside: Study name & randomization number Inclusion / exclusion criteria 1 King mask 1 ITD (mini extension tube attached) Paramedic Data Collection Sheet 1 Arm Band “Notification of Study Enrollment” Sheet “Research Data Collection Envelope” Extra labels with randomization number

After Transfer of Care

ITD Packaging & Randomization Labels Randomization Labels

Hospital Documentation After you have transferred care to the ED staff please ensure the following has been completed: The patient bracelet has been placed on the patient’s arm The “Notification of Study Enrollment” sheet has been given to the documenting nurse A study label has been affixed to the ED chart

Your Documentation Please ensure the following has been completed: “ROC PRIMED Paramedic Data Collection Sheet” Adverse events or concerns have been reported Study labels have been affixed to: the ACR (white & yellow copies); and “Research Data Collection Envelope” the patient’s chart All documents have been placed in the “Research Data Collection Envelope” Upload defibrillator data
