Immediately assess the situation. If the individual is unresponsive and not breathing, initiate chest compressions. Position your hands on the center of the chest, just below the sternum. Ensure your elbows are straight and shoulders are aligned over your hands for maximum force. Press down hard and fast, aiming for a depth of at least 2 inches (5 cm), at a rate of 100-120 compressions per minute.
After every 30 compressions, provide two rescue breaths. Tilt the head back to open the airway and pinch the nostrils. Give a breath that lasts about one second, making sure the chest rises with each breath. Continue alternating between chest compressions and rescue breaths until professional help arrives or the person shows signs of recovery.
If you’re unsure about performing rescue breaths, chest compressions alone can significantly improve the person’s chances of survival. Always ensure you’re using the correct depth and rate to maximize circulation to the brain and vital organs.
Answers to Basic Life Support Exam A
Begin chest compressions immediately for an adult with no pulse, aiming for a depth of at least 2 inches (5 cm) and a rate of 100-120 compressions per minute.
If a child is unresponsive and not breathing, check for a pulse for no longer than 10 seconds. If no pulse is detected, initiate compressions and ventilations, ratio 30:2, for one-rescuer CPR.
For infants, compress the chest about 1.5 inches (4 cm) and maintain the 30:2 compression-to-ventilation ratio for a single rescuer. Use two fingers for chest compressions.
If an AED is available, turn it on, follow the voice prompts, and place the pads on the patient’s bare chest. Do not touch the patient while the device is analyzing or delivering a shock.
If a person becomes conscious after a shock, monitor their airway and breathing, but avoid giving food or drink. Keep the patient in a stable position and avoid movement until emergency help arrives.
When two rescuers are present, switch compressions every 2 minutes to avoid fatigue and maintain the quality of chest compressions. Keep the ratio of compressions to breaths at 30:2 for adults and children, and 15:2 for infants when two rescuers are involved.
In case of choking, perform back blows and abdominal thrusts for adults and children over 1 year old. For infants, use a combination of back slaps and chest thrusts.
For drowning victims, provide two initial breaths before starting chest compressions, and continue CPR as usual, adjusting for the victim’s age and condition.
Steps for Assessing Consciousness in an Adult
To evaluate an adult’s consciousness level, follow these precise steps:
- Check for Responsiveness: Gently tap the person’s shoulder or arm and loudly ask, “Are you okay?”
- Use a Clear Voice: Speak in a normal tone, ensuring you do not shout. Refrain from using confusing or exaggerated language.
- Assess Eye Movement: Observe whether the person is able to open their eyes or respond to visual stimuli.
- Apply a Pain Stimulus: If no verbal response, apply a firm pinch to the upper arm or earlobe to check for any reaction.
- Evaluate Response: If there is no verbal or physical response, the person may be unconscious or in a deep altered state.
If the person remains unresponsive after these steps, proceed with further medical evaluation or intervention. Remember that a timely response is key to addressing potential risks or injuries.
How to Check for Breathing and Pulse in Emergency Situations
To assess if someone is breathing, position the person on their back. Place your ear close to their mouth and nose while watching their chest. Look for chest movement, listen for breathing sounds, and feel for air on your cheek. Do this for no more than 10 seconds. If there is no visible chest movement or breath sounds, the person may not be breathing. In such cases, begin CPR immediately.
For checking the pulse, use the index and middle fingers to press on the carotid artery on the side of the neck. Apply gentle pressure about halfway between the ear and the Adam’s apple. Count the pulse for 10 seconds. If no pulse is detected, CPR should begin right away.
If the person is unconscious, breathing irregularly, or no pulse is felt, call emergency services and begin resuscitation efforts without delay.
| Action | Steps |
|---|---|
| Check for Breathing | 1. Position the person on their back. 2. Place your ear near their mouth and nose. 3. Watch for chest movement, listen, and feel for breath. 4. Perform for no more than 10 seconds. |
| Check for Pulse | 1. Use index and middle fingers. 2. Apply pressure to the carotid artery on the neck. 3. Count pulse for 10 seconds. |
When performing these checks, it is important to stay calm and focused. Time is critical in emergencies, and quick, precise actions can make a difference in survival.
Proper Chest Compression Technique for CPR
Position your hands in the center of the chest, just below the nipple line. Interlock your fingers and keep your arms straight, with your shoulders directly over your hands. Use your body weight to compress the chest at least 2 inches (5 cm) deep in adults, allowing full recoil after each compression. Aim for a compression rate of 100 to 120 per minute. Avoid leaning on the chest between compressions and maintain consistent rhythm. Ensure that compressions are strong and deep, but not too fast, to allow the heart to refill with blood. Proper hand placement and depth are key to circulating oxygen-rich blood effectively.
How to Use an AED Correctly
Place the AED near the person in need of help. Ensure the area is clear of any obstructions, and make sure the victim is lying flat on their back on a firm surface.
Turn on the AED by pressing the power button. Follow the audible or visual instructions provided by the device. Remove clothing from the chest to expose the skin. If necessary, use scissors included in the AED kit to cut through clothing.
Apply the electrode pads to the victim’s bare chest. One pad should be placed on the upper right side of the chest, just below the collarbone. The second pad should be placed on the lower left side, a few inches below the left nipple.
Ensure the pads adhere firmly to the skin, with no clothing or objects between them. The AED will automatically analyze the heart rhythm. Do not touch the victim during this analysis phase to avoid interference with the readings.
If a shock is needed, the AED will instruct you to press a button to deliver it. Make sure no one is touching the victim, and then push the button to administer the shock.
If the AED advises no shock is necessary, begin CPR immediately, starting with chest compressions. Continue following the AED’s prompts, administering shock when instructed, and performing CPR until medical professionals arrive.
After a shock is delivered, continue to monitor the victim. If the person remains unresponsive, resume CPR as directed by the AED, and repeat the process until help arrives or the victim shows signs of recovery.
Handling Obstructed Airway in a Conscious Adult
In a conscious adult, if the airway becomes obstructed, immediate action is required to prevent suffocation. The primary maneuver is the Heimlich maneuver, which applies pressure to the diaphragm to expel the foreign object. This technique should be used only if the person is unable to breathe, cough, or speak.
Follow these steps:
- Assess the situation: Determine if the person is truly choking. If they are coughing forcefully or able to speak, encourage them to continue coughing to clear the obstruction.
- Stand behind the person: Position yourself behind them, wrapping your arms around their waist. Keep your hands in a fist and place the thumb side just above the navel.
- Perform abdominal thrusts: Grasp your fist with your other hand and give quick, inward and upward thrusts. This action increases pressure in the abdomen, forcing air upward and potentially dislodging the object.
- Repeat if necessary: Continue performing thrusts until the object is expelled or the person becomes unconscious.
If the person becomes unconscious:
- Call emergency services immediately.
- Start chest compressions, as this may help dislodge the object.
- Open the mouth to check for the object, but do not blindly reach into the throat. If visible, attempt to remove it using a finger sweep.
In situations where the Heimlich maneuver is ineffective or the victim collapses, begin CPR, as the blockage may still be present in the airway.
CPR Protocol for Children and Infants: Key Differences
For infants (under 1 year old) and children (1 to 8 years old), CPR procedures differ significantly from those for adults. Here’s what needs to be applied:
| Procedure | Infants (Under 1 Year) | Children (1-8 Years) |
|---|---|---|
| Chest Compressions | Use two fingers at the center of the chest, just below the nipple line. Compress the chest at least 1/3 the depth of the chest (about 1.5 inches). | Use one or two hands depending on the child’s size. Compress the chest at least 1/3 the depth (about 2 inches). |
| Rescue Breaths | Cover the infant’s nose and mouth with your mouth. Give gentle breaths, ensuring the chest rises. | Pinch the child’s nose and cover the mouth with yours. Deliver breaths until the chest rises. |
| Compression-to-Ventilation Ratio | 30:2 if alone. 15:2 if with two rescuers. | 30:2 for a single rescuer, 15:2 for two rescuers. |
| Defibrillation | Use pediatric pads if available. If not, adult pads can be used, but ensure they don’t touch. | Use pediatric pads if possible, otherwise, adult pads can be used with caution. |
| Head Tilt-Chin Lift | Avoid excessive tilting of the head; a neutral position is preferred to open the airway. | Normal head tilt and chin lift to open the airway. |
The key differences are in the compression technique and the method of rescue breaths. For infants, a gentler touch is required, and the airway should be managed carefully to prevent injury. With children, the technique is closer to adult CPR, but modifications are made for their smaller size and needs.
When to Call for Emergency Medical Assistance During CPR
If a person is unresponsive and not breathing normally, call emergency services immediately. Do not delay even if CPR is in progress, as professional intervention is critical for a successful outcome. When you are performing chest compressions and rescue breaths, call for help after ensuring that the scene is safe. If you are alone, initiate CPR for about 1-2 minutes before dialing emergency services, unless the person is an infant or child, in which case, call right away. If the victim is showing signs of a cardiac arrest or severe trauma, do not hesitate to call for medical assistance immediately.
If the person regains some consciousness, but is still struggling to breathe, make the call for emergency responders. If there is no immediate response after 2 minutes of CPR, or if you cannot perform effective chest compressions, it is time to seek urgent professional aid. Continuous care is needed until trained paramedics arrive, as their interventions can make a significant difference.
If a defibrillator is available, use it immediately. If you are unsure whether to use one, place the device and follow the instructions to allow it to assess the heart rhythm. Even if you are performing CPR well, do not stop compressions unless a defibrillator is applied or you are relieved by emergency personnel.
Post-Rescue Care: How to Monitor and Stabilize Victim
Ensure the victim’s airway is open. Check for any obstructions and clear the mouth or throat if needed. Keep the head tilted back and chin lifted to maintain airflow.
Monitor breathing and pulse. If absent or irregular, continue artificial respiration and chest compressions until medical personnel arrive. Use a pulse oximeter if available to assess oxygen saturation levels.
Maintain victim’s body temperature. Cover with a blanket or clothing to avoid heat loss, especially in cold environments. Prevent overheating by adjusting layers if necessary.
Assess for any signs of shock, such as pale skin, rapid breathing, and weak pulse. Keep the victim lying flat and elevate their legs if shock is suspected, unless there’s a head or spinal injury.
Continuously monitor the victim’s condition for changes. If consciousness returns, keep the victim calm and still, and avoid giving fluids or food unless advised by medical professionals.
Ensure the victim is in a safe position, such as the recovery position, if unconscious but breathing. This will help maintain an open airway and prevent choking.
Communicate any relevant details to responding emergency services, including the time of rescue, initial condition, and any interventions performed.
- Airway: Ensure it’s clear and open.
- Breathing: Observe closely, intervene if necessary.
- Pulse: Monitor for consistency and strength.
- Temperature: Prevent heat loss or overheating.
- Shock: Recognize symptoms and manage accordingly.
Never leave the victim unattended, and continue monitoring until professional medical care takes over.
