AED Pad Placement – Where to Put Pads on Adults & Children

Automated External Defibrillator pads (also known as AED electrode pads) are an essential part of any lifesaving AED machine. These pads are placed on the bare chest of a person who is suspected to be suffering from Sudden Cardiac Arrest (SCA). Once placed on the chest, the AED unit can determine if the person’s heart is in a lethal rhythm that needs to be treated with a defibrillation shock. If the AED determines a shock is needed, electricity is safely administered to the person through the electrode pads to restart their heart back into a normal rhythm. 

In this guide, we’ll discuss everything you need to know about where to place AED pads on adults and children. Before diving in, let’s discuss the different types of AED pad placement.

Anterior Posterior Pad Placement & Anterior Lateral Pad Placement

Common technical terms you will hear to describe defibrillator pad placement include “anterior-posterior” and “anterior-lateral. ” What do these terms actually mean? 

First, let’s define anatomical position. Anatomical position refers to the standard position that the body is oriented when using describing position with terms such as anterior, posterior, and lateral. Specifically, standard anatomical position is when the body is essentially equivalent to what you would see when someone is flat on their back, palms and toes facing forward, and both the arms and legs slightly separated so they are not touching the torso or each other.

Anterior posterior or anteroposterior means the “front and back” of the body in this standard anatomical position. A feature that is anterior to another is closer to the front of the body whereas a feature posterior to another is located closer to the back of the body. In the case of AED pads, this specifically means that one AED pad is placed on the front of the chest while the other AED pad is placed on the back as seen in the illustration. 

As for anterior lateral or anterolateral , this is equivalent to “toward the front” and “towards the edge” in standard anatomical position. Anterior features are closer to the front of the body while lateral features are closer to the edge of the body. This type of defibrillator pad placement is when one AED pad is placed on the right side of the chest (just below the collarbone) while the other pad is put on the lower left side of the chest. 

One great thing about AED electrode pads is that the pads have graphics on them that show you where to place them on the body. Remember: all defib pads must be placed directly on bare skin!

Where to put AED pads on Adults?

AED pad placement is the same for all adults. Where you put AED pads on a woman = where you put AED pads on a man = where you put AED pads on a pregnant woman. It’s all the same! 

The electrode pad placement might vary from one AED brand to the next, so be sure to check your AED’s owner’s manual for specific electrode pad placement instructions. If you can’t find it there, most AEDs have an image printed directly on the electrode pads that show where they should be placed on a person’s body.

Where to put AED pads on Children?

There are several additional considerations when it comes to placing AED pads on a child. Read more about the specifics of child defibrillator pad placement with our Pediatric AED Pad Guide. 

Frequently Asked Questions

What are Defibrillator Pads Made of?

AED pads are made of plastic, metal, and a conductive adhesive gel that sticks to the patient and helps deliver lifesaving defibrillation shocks.

Can I Reuse AED Pads?

No, AED electrode pads are single-use and must be replaced after they are used for an emergency or when they expire. Expiration dates for different AED pads vary by manufacturer. Learn more about the cost, usable life, and more for different AED pads with our AED Electrode Pad Guide. (link to AED comparison about electrode pads).

Can You Use an AED on Someone with a Pacemaker

AEDs can be used on patients with a pacemaker, however, do not apply the AED’s electrode pads directly over an implanted pacemaker in the patient. As always, check your AED’s user manual for more information.

Correct AED Pad Placement – First Aid for Free

An Automated External Defibrillator (AED) is a medical device that delivers an electrical shock to a victim in cardiac arrest. A cardiac arrest occurs when a victim’s heart stops beating and blood stops flowing around the body.

Unfortunately, sudden cardiac arrest has a poor outcome unless a victim receives timely CPR and defibrillation. To improve survival from cardiac arrest there is now a push to have more publically accessible AEDs. Many workplaces, educational institutions, and public buildings now have an AED installed and have trained staff in its use.

AEDs are designed to be used by laypeople with no medical training, however, the American Heart Association (AHA) does advise potential operators of an AED to have basic training in its use and CPR. 

AED Pad Placement is Vital

An AED delivers a shock to a victim using two pads placed directly onto the victim’s chest. The positioning of these pads is important, as the electrical shock needs to travel through the heart muscle. 

The first pad is placed underneath the victim’s collarbone (clavicle). The second pad is placed on the left chest wall, underneath the armpit. As the diagram shows, this allows the electrical shock to travel through the victim’s heart.

Most AED pads come with written and visual instructions on where the place the pads.

Adult Pad Placement

Unless otherwise stated in the AED instructions, one AED pad should be placed on the upper right-hand side of the victim’s chest, underneath the collarbone. The other should be placed on the lower left side of the chest wall, below the armpit, as shown in the diagram above. 

This is the same for all adults, no matter whether they are male or female, young or old, or even if they’re pregnant.

AED Pad Placement on an Infant

First, check to make sure that the infant isn’t choking. Most cardiac arrests in infants under the age of one are due to a blockage in their airway rather than an isolated issue with their heart. So first, observe the infant for signs of choking, and if found, follow the guidance outlined in our post about airway obstruction in children and infants. 

Once you have ruled out a choking emergency, adjust the AED pads to the child setting. Most AED devices have this feature, and switching between adult and child modes is simple. However, in the unlikely event that only adult mode is available, the American Heart Association (AHA) recommends you still administer the shock, rather than doing nothing at all.

No matter what type of AED pads or mode you are using, they should be placed in a ‘front and back’ position (the anterior-posterior position), with one pad on the center of the front of the chest, and the other on the center of the infant’s upper back. Be sure the pads are not touching. 

Child Pad Placement

American Heart Association (AHA) recommends pediatric AED pads for children below the age of 8, or anyone weighing less than 25kg (55lbs). 

If you are unsure of the victim’s age or weight, quickly check with any close bystanders (do not leave the victim unattended) and use your best judgment.  

Child AED pad placement is the same as the anterior-posterior/ front and back infant pad placement outlined above. Place one pad on the center of the front of the chest and the other on the center of the child’s upper back. 

AED Pad Placement on a Pregnant Woman

According to guidance issued by the American Heart Association (AHA), if a pregnant woman suffers a cardiac arrest, it is safe and necessary to use an AED. 

Pad placement is the same as the placement for all adults: one pad should be placed on the upper right-hand side of the chest, above the right breast, and underneath the collarbone. The other should be placed on the lower left side of the chest wall, below the armpit,

Important: When calling 911, be sure to inform the operator that the victim is pregnant. In the event that the mother dies, medics may still be able to save the baby if medical assistance is sought quickly enough. 

AED Pad Placement for Cardiac Arrest Victims with a Pacemaker

AED devices should still be used if the cardiac arrest victim has a pacemaker. A pacemaker is a device installed in a patient’s chest to regulate the heart’s rhythm. The location of this device will depend on where you place the AED pads. 

Usually, pacemakers are installed in the upper left region of the patient’s chest. If this is the case, no modification is needed. Use the default pad placement required for all adults: one pad on the upper right-hand side of the chest, underneath the collar bone, and the other on the lower left side of the chest wall, below the armpit. 

Suppose the pacemaker is located on the upper right-hand side of the patient’s chest. In that case, you will need to modify the pad position slightly by placing the AED pad at least one inch to the side, or below, the pacemaker. As normal, the second pad should be placed on the lower left side of the chest wall, below the armpit.

Common AED Pad Placement Mistakes

The second pad placed on the left side of the chest wall should be positioned underneath the victim’s armpit. A common mistake is to place this pad on the front of the chest, this is likely to make an AED shock less effective.

AED pads need to be placed in direct contact with the skin. Excessive chest hair can reduce pad contact with the skin and risk causing burns. Many AEDs come with a small razor in order to remove chest hair before pad placement. 

Aerological diagram. How to read and what you can learn from it.

Can you predict from it? :

  • Cloud base (lower boundary);
  • Height of thermals available for vaping;
  • Force, average rate of climb and turbulence of flows;
  • Retaining layers in which the thermal will flex and misbehave;
  • View of clouds;
  • How well the clouds will perform;
  • How quickly the clouds will evaporate after the death of the stream and whether they will spread, covering the sun with crises;
  • Will the “cloud banks” work and is it possible to fly “dolphin”;
  • How does the wind change with height;
  • Will there be tornadoes, sharp downdrafts and how they will be distributed vertically;
  • Is there a danger of overdevelopment of clouds;
  • Will it rain, thunderstorms;
  • At what height is it most efficient to fly;
  • Will it be possible to evaporate “from the bottom”;
  • and much, much more.

Let’s figure out how to read all this on this chart.

To begin with, let’s analyze what is an aerological diagram (AD)? – So.

An upper-air diagram is a series of data describing the state of the air in height. These data are represented by 2 air condition curves and wind values.

  • The 1st curve is located on the left, usually bold, green , called – depegram (depegram) or “dew point” curve. This curve (in degrees C) shows the temperature of air saturation with water, that is, at what temperature, moisture will begin to condense from the air at a particular level. At its core, it conveys the absolute moisture content of the air at a given altitude.
  • 2nd curve, on the right, usually bold red , is called “ stratification curve ” and it shows the air temperature at a given altitude. Stratification can be stable, unstable and indifferent to dry (and unsaturated) or saturated air.
  • Distance between stratification curve and depegram shows dew point deficit ∆=T-Td.
  • Wind data, mainly located to the right of the BP form and indicate the direction and speed of the wind at each altitude level, sometimes supplemented by the hodograph of the sonde offset in height. (a curve showing where the probe moved during the ascent, it clearly shows where and how the wind turns in height).

These 2 curves and wind data are obtained by from atmospheric soundings (often referred to as sounding ) meteorological balloons (usually 2 per day, at 0000 and 1200 standard time UTC ), or they are obtained from the results of numerical simulation for those points where there is no sounding or in the forecast for the future.

Curves are applied to a special form upper-air diagram , this blank nomogram describes the thermodynamic properties of air .

Upper air diagram lines .

The following lines are applied to BP:

  • Isobar (equal pressure) – horizontal dashed lines – show the same height (pressure) along the entire line. The numbers on the right are altitude or pressure in mbar. Pressure indicates altitude. As a first approximation, we can assume that:
    • 1000 mbar = 100m
    • 900 mbar = 1 km
    • 800 mbar = 2 km
    • 700 mbar = 3 km
    • 500 mbar = 5.5 km
  • Isotherm (equal temperature) – vertical thin red or brown lines on the ADP form and slanted to the right on the ADC form, at an angle of 45 degrees. to isobars (height) (that’s why the form is called oblique ) – they show the same temperature along the entire line. The brown numbers on the left and bottom are the temperature of the isotherms.
  • Isograms (equal to “dew points”) – usually a green thin dotted line, show how the dew point changes when air rises with a certain humidity. about 0.2 degrees per 100m altitude.
  • Dry adiabats (SAG=DALR) gray lines inclined to the left, – they describe changes in air parameters moving according to the dry adiabatic law (that is, in the absence of moisture condensation). Or simply – the lines of the dry adiabatic gradient. SAG is about 9.8 hail per 1 km altitude.
  • Wet adiabats (VAG=SALR) – blue curved lines , changes in air parameters moving in the humid adiabatic law (that is, under the condition of moisture condensation). Or simply – the lines of the wet adiabatic gradient. The lines are curved, since the wet adiabat strongly depends on pressure (altitude) and air temperature. (the warmer the air, the more moisture dissolves in it and the more “latent heat” is released during its condensation. VAG changes from 4 to 8 degrees per km of altitude. The colder the air, the less moisture it contains and the closer VAG approaches SAG .

VAG change depending on pressure and temperature.

  • To the right of the BP field there are “flags” showing the direction and speed of the wind in meters per second or knots and the direction in degrees. For example, 90 (5) means that an east wind of 5 m/s is blowing at a given height.
  • Top left, often draw a probe drift hodograph. The concentric circles indicate the speed, and the shift of the graph in one direction or another indicates the direction of the drift.

Aerological Diagram Forms.

There are 3 main types of forms, emagram (aka ADP ), Tepigram and Skew-T log P (aka ADK ) they differ in the angles of intersection of the lines describing the fundamental characteristics of air (first of all pressure (height), temperature, and dry adiabatic law

Airfoil chart blanks meet the following requirements:

  1. Designed so that the area on the diagrams is proportional to the energy.
  2. The underlying lines were straight and therefore easy to use.
  3. On ADC / upper-air log in oblique coordinate system/ ( Skew-T log P ) – skew isotherms (T) are almost perpendicular to SAG (dry adiabatic gradient).

It is important that the SAG ( isentropes ) and isotherms be far apart to help us see small temperature changes relative to the SAG, which is important in determining stability.

Let’s look at the example of ADC (aka Skew-T log P).

Isobars (height)

Isograms

Isograms

Isograms – lines of equal specific humidity in saturation They show at what temperature and at what height the air mass of a given humidity will reach a state of saturation ( dew point ).

Further rise of this air would lead to condensation and cloud formation.

Isotherms

Isotherms – constant temperature lines. For convenience, in ADC, they are arranged obliquely from left to right.

Dry adiabats (isanthropes) or

SAG (DALR in English diagrams)

SAG or isanthropes particles of dry or moist unsaturated air when it is lowered or raised.

The dry adiabatic temperature drop of the rising air is approximately 0.98°C/100m.

SAG lines are directed from right to left.

Wet adiabats or lines VAG (SALR in English)

VAG

Indicate the adiabatic temperature change of a particle of humid air 9000 4 when lowering or raising it, subject to condensation (evaporation) of moisture.

When moisture condenses, additional “hidden” energy is released, which reduces the temperature drop when air rises compared to an unsaturated state, as in SAG.

VAG (wet-adiabatic gradient) strongly depends on the amount of heat generated (hence air temperature and pressure (height)) VAG can vary from 0.3 to 0.98°C/100m).

In very cold air – humid adiabatic parameters are close to dry adiabatic .

All together the lines form the ADC form (

Skew-T log P)

ADC Form

actual air temperatures (stratification curve) and wind data.

Also on the BP form, the “ state curve ” is usually built.

Status curve – characterizes changes in air temperature in adiabatically rising air particle . Usually, the air contains a certain amount of water vapor, therefore, up to the level of condensation, the state curve is drawn along the dry adiabat (SAG), above the level of condensation – along the wet adiabat (WAG).

Simply put, the state curve describes what will happen to an isolated volume of air rising at a given temperature near the surface, in an atmosphere with given values ​​of the stratification curve and depegram. If we build a state curve for a temperature equal to the average at the surface, then it will show the law of air rise during mechanical (for example, orographic – due to relief) transfer, if we take the initial temperature equal to the layer of air “superheated” above the thermal formation zone (usually by 3 -4 degrees higher than the average at the surface) then the state curve will describe what will happen to the air rising in the thermal (bubble).

Based on the results of the mutual analysis of the stratification, state and depegram curves, INSTABILITY ANALYSIS is carried out, and a number of weather parameters and base levels of interest to us can be found.

Such as:

  • Real temperature at any height isotherm.
  • Condensation level is the level to which water vapor must be raised so that the water vapor contained in the air, during adiabatic rise, reaches a state of saturation (or 100% relative humidity) and moisture condensation begins. This level will help predict whether there will be clouds and what kind of base they will have. To determine the level of condensation, you need to choose what type of level we need – during convection (thermal) or during mechanical transfer (for example, orographic rise). For mechanical lifting (Lifting Condensation Level ( LCL )) – it is necessary to move along the dry adiabat from the sounding height (surface) from the air temperature value, and along the isogram from the dew point value, the level of their intersection is the level of condensation. For thermal convection, (Convective Condensation Level ( CCL )) it is necessary to take the temperature near the ground a few degrees higher than that measured by the probe. This will be the “thermal superheat” temperature relative to the ambient air.
  • Temperature inversion levels .
  • At what height is there dense clouds , and what layer it occupies in height (if any). For example, if the graphs of temperature and dew point are in contact, we have a dense stratus cloud. Stratified, not cumulus, because such conditions exist throughout our area.
  • Rainy day – if these two graphs simultaneously go from below and to a high altitude (this means that over the entire height we have 100% humidity)
  • The strength and direction of the wind at a given height on the right side of the diagram and the hodograph (if any).

Also, by analyzing the chart, one can judge the predictive weather dynamics, for example, the approach of an atmospheric front, the possibility of clouds spreading, etc. The very process of determining different levels and recognizing different types of weather, I will describe in separate articles, in section theoretical meteorology . And I want to finish this article with links to resources where you can download the current diagrams.

  • First of all Flymeteo.org – on this site you can download the actual real data of the TRS at 00 and 12 UTC for many points in Russia and in the world. All charts are in a perfectly readable form and processed, that is, they highlight the basic levels and meteorological phenomena.
