How To Make Push Dose Epi: A Complete Clinical Guide For Resuscitation
Push dose epinephrine, also known as bolus vasopressor therapy, provides an essential, short-term bridge for managing acute intra-arrest or peri-intubation hypotension. By diluting standard cardiac arrest concentrations into a low-dose, titrated IV push format, clinicians can rapidly restore coronary and cerebral perfusion pressure without waiting for continuous infusion pumps to prime.
Preparing for Safe Preparation and Administration
Executing push dose epinephrine safely requires strict adherence to standardized dilution protocols to prevent devastating medication errors. Because epinephrine is a potent catecholamine, miscalculating concentrations can easily trigger severe hypertensive crises, reflex bradycardia, intracranial hemorrhage, or fatal tachyarrhythmias. Clinicians must approach this preparation with the same mathematical precision utilized in pediatric dosing or continuous vasopressor titration.
- Essential supplies include one 10 mL normal saline flush syringe, one ampule or vial of epinephrine 1:1,000 or 1:10,000, a sterile 10 mL or 20 mL empty syringe, an 18-gauge needle for drawing, and an alcohol swab.
- Mandatory clinical prerequisites include verifying the patient's weight, establishing secure intravenous or intraosseous access, ensuring continuous electrocardiographic monitoring, and having an automated blood pressure cuff set to cycle every one to two minutes.
- Estimated preparation duration is under 60 seconds when following standardized dilution pathways, making this an ideal rapid-response intervention for crashing hemodynamics.
Step-by-Step Dilution and Administration Workflow
Step 1: Gather the Correct Medications and Equipment
Locate a standard concentration of epinephrine. Emergency departments and intensive care units typically stock epinephrine at 1:1,000 (1 mg/mL) in ampules or 1:10,000 (0.1 mg/mL) prefilled syringes. Verify the concentration printed on the packaging twice before proceeding to prevent tenfold dosing errors.
Warning: Never administer undiluted 1:1,000 epinephrine intravenously. This concentration is intended strictly for intramuscular or endotracheal use; IV administration of 1 mg directly can cause immediate cardiac arrest from ventricular fibrillation.
Step 2: Prepare the 10 Microgram per Milliliter (10 mcg/mL) Dilution
To achieve the standard push dose concentration of 10 mcg/mL, take your empty 10 mL syringe and draw up 1 mL of epinephrine 1:1,000 (which equals 1 mg or 1,000 mcg). Next, draw 9 mL of normal saline (0.9% NaCl) into that same syringe containing the 1 mL of epinephrine. You now have a total volume of 10 mL with a final concentration of 100 mcg per 10 mL, or precisely 10 mcg per 1 mL. Alternatively, if starting with a 1:10,000 prefilled syringe, eject 1 mL of flush from a 10 mL normal saline flush and replace it with 1 mL of the 1:10,000 epinephrine to yield a similar low-dose preparation.
Pro-Tip: Clearly label the syringe immediately with a waterproof marker or pre-printed label reading "Epinephrine 10 mcg/mL" to ensure other team members do not mistake it for a standard saline flush.
Step 3: Calculate and Administer the Appropriate Dose
Assess the patient's current hemodynamic status and clinical presentation. The standard adult starting dose for push dose epinephrine is 10 to 20 mcg (1 to 2 mL of your prepared solution) administered via IV push over a few seconds. Repeat every 1 to 2 minutes as needed while titrating to a target mean arterial pressure or systolic blood pressure, keeping in mind that the onset of action occurs within 30 to 60 seconds and the duration is brief (typically 5 to 10 minutes).
Step 4: Monitor and Transition to a Continuous Infusion
Observe the patient's heart rate, rhythm, and blood pressure continuously following every administration. Document the exact timing and volume of each bolus given. If the patient requires more than two or three consecutive push doses within a short window, immediately initiate a continuous vasopressor infusion such as norepinephrine or epinephrine to maintain hemodynamic stability.

Comparative Overview of Epinephrine Concentrations and Dilutions
| Parameter | 1:1,000 Concentration | 1:10,000 Concentration | Push Dose (10 mcg/mL) |
|---|---|---|---|
| Total Drug Amount | 1 mg per 1 mL | 1 mg per 10 mL | 100 mcg per 10 mL |
| Primary Route | IM, Subcutaneous, Nebulized | IV / IO Cardiac Arrest | IV / IO Peri-arrest Bolus |
| Calculated Risk | Extreme risk of fatal overdose if given IV push | High risk of severe hypertension if given rapidly | Low risk when titrated correctly in small increments |
| Onset of Action | 3 to 5 minutes (IM) | Immediate (1 to 2 minutes) | 30 to 60 seconds |
| Clinical Indication | Anaphylaxis, severe asthma | Cardiac arrest, pulseless arrest | Post-intubation hypotension, shock states |
Troubleshooting Common Dilution and Administration Errors
- Root Cause: Mixing up 1:1,000 and 1:10,000 concentrations during the high-stress dilution process, resulting in a tenfold overdose. Actionable Fix: Always double-check ampule labels out loud with a nursing colleague or pharmacist before drawing medication, and utilize standard institutional pre-calculated dilution charts.
- Root Cause: Administering the push dose through a peripheral line with poor or sluggish flow, leading to localized extravasation. Actionable Fix: Confirm brisk blood return and patency of the IV catheter before pushing any vasopressor medication; use a proximal site or central line whenever possible.
- Root Cause: Failing to initiate a continuous infusion while relying indefinitely on repeated push doses. Actionable Fix: Treat push dose epi strictly as a temporary bridge. The moment a second or third bolus is required, order and prime a continuous infusion pump immediately.
- Root Cause: Patient develops severe reflex bradycardia or acute hypertension following administration. Actionable Fix: Pause further boluses, monitor the rhythm strip for ischemia, and allow the short-acting agent to wear off while assessing whether a pure inotrope or alternative agent is more appropriate.
Frequently Asked Questions
What is the exact concentration of push dose epinephrine?
The standard concentration for push dose epinephrine is 10 micrograms per milliliter (10 mcg/mL). This is safely achieved by diluting 1 mg of epinephrine into a total volume of 100 mL of normal saline, or more commonly in emergency settings, 1 mL of 1:1,000 epinephrine into 9 mL of normal saline in a 10 mL syringe.
How long does a single push dose of epinephrine last?
The hemodynamic effects of a push dose of epinephrine typically begin within 30 to 60 seconds of administration. The peak effect occurs around 2 minutes, and the overall duration of action is brief, lasting approximately 5 to 10 minutes.
When should push dose epinephrine be used in clinical practice?
Push dose epinephrine is indicated for transient, acute hypotensive crises where immediate intervention is required to prevent cardiac arrest. Common clinical scenarios include post-intubation hypotension, refractory shock during line placement, or sudden blood pressure drops during procedural sedation.
Can push dose epinephrine be given through peripheral IV lines?
Yes, push dose epinephrine can be administered through a peripheral intravenous line in emergency settings when central venous access is unavailable. Clinicians must ensure the line is verified as patent with a free-flowing flush to minimize the risk of severe local vasoconstriction and tissue necrosis from extravasation.
