In an urgent situation where a adult or child is unresponsive, the first instinct is to check for movement or vocalization. Stand close enough to feel a pulse-area breath, then carefully tilt the head back to open the airway. Avoid twisting the neck if you suspect a spinal injury. If you cannot detect any response after shouting and approaching the person, prepare to initiate life-saving actions without delay. Your goal is to confirm unresponsiveness and assess whether breathing is present, regular, and adequate. This assessment should be concise, precise, and performed with calm efficiency to maximize the person’s chances.
Begin by calling out loudly to the person and giving a gentle shake of the shoulder to elicit a reaction. If there is no response, immediately assess breathing by observing chest movement, listening for breath sounds, and feeling for air on your cheek for no more than ten seconds. Time is critical because delays can lessen the chance of survival. If breathing is absent or irregular, you must proceed to CPR steps as recommended by guidelines. If there is any sign of breathing, place the person in a recovery position while continuing to monitor their condition and prepare additional help or an automated external defibrillator if available.
Quick, calm evaluation guides appropriate immediate response.
When approaching an unresponsive person, your first action is to assess safety for both of you. Ensure the surroundings are free of hazards, and identify bystanders who can assist with calling emergency services or getting an AED. After you verify your own safety, move to determine consciousness by speaking firmly and tapping the person’s shoulder. If there is no discernible response, proceed to breathing assessment. Use the watch as a timer and track the duration of your observation; a rapid but thorough evaluation helps you determine whether to start chest compressions or continue to monitor. Your clarity in this moment prevents hesitation that could cost valuable seconds.

A reliable breathing check relies on simple cues. Observe the chest for rising and falling, listen for breath sounds, and feel for exhaled air. Do not overthink the process; rely on a standard ten-second window. If you detect continuous, normal breathing, turn the person onto their side in the recovery position to maintain airway patency while you wait for help. If breathing is absent or inconsistent, begin CPR immediately, starting with chest compressions. In both scenarios, keep the airway open and avoid interrupting effective breathing if it exists. Stay composed, check again if unsure, and escalate to professional care without delay.
Proper assessment prevents delays in life-saving action.
If you encounter a person who is unresponsive with a faint pulse or shallow breathing, you still must act quickly but safely. Reconfirm that you are in a safe location and that help is on the way. At this point, if the person is not breathing or is struggling to breathe, begin CPR, starting with chest compressions to circulate oxygenated blood. If a bystander is available, assign one to call emergency services while you perform compressions. Use the appropriate technique for age and size, and ensure your hands are placed correctly on the center of the chest. Maintain a consistent rhythm and allow full chest recoil between compressions to maximize effectiveness.

After initiating chest compressions, continue until the person resumes breathing, professional responders arrive, or you are physically unable to continue. If an AED becomes available, turn it on and follow the prompts promptly. If the person regains consciousness, place them in the recovery position and monitor breathing while awaiting further medical evaluation. Throughout the process, keep yourself physically, emotionally, and mentally steady so you can deliver high-quality compressions. Your steadiness helps you maintain correct technique and avoid fatigue that could compromise care.
Training and practice sharpen instincts in critical moments.
A successful breathing assessment hinges on concise observation. Watch the chest for regular movements that indicate breathing, and listen for consistent breaths without gasping. If you observe cooperative breathing, place the person gently on their side to maintain an open airway, then stay nearby to monitor changes until emergency help arrives. If breathing is absent, initiate cycles of chest compressions immediately. Remember to minimize interruptions; each pause for breath checks should be brief and purposeful. Your ability to interpret subtle changes in breathing patterns can prompt a timely switch to rescue breaths if trained, or reliance on continuous compressions when resuscitation is in progress.
Different situations require careful adaptation. For example, an unresponsive child or infant demands gentler handling and age-appropriate technique. In such cases, gently tilt the head back and give two breaths at the outset after confirming unresponsiveness. Then proceed with cycles of compressions appropriate for the pediatric population. If you are alone, call for help first but do not delay starting CPR if no one answers promptly. With continued practice and familiarity with responses, you will become more proficient at distinguishing between normal, shallow, and absent breathing, allowing you to act decisively when it matters most.

Ready action hinges on knowledge, rehearsal, and calm execution.
The initial assessment of consciousness and breathing should be rapid, structured, and repeatable. Approach each step with confidence and a clear plan to minimize hesitation. If the person speaks, respond calmly to assess their orientation, memory, and ability to follow simple commands. If there is no response, transition to breathing evaluation and begin CPR as indicated. Your ability to deliver a smooth, efficient initial assessment sets the stage for effective resuscitation and increases the likelihood of a favorable outcome for the unresponsive person.
As you gain familiarity with the process, you’ll become adept at handling chaotic scenes. Maintain control by directing bystanders to organize an emergency call, fetch an AED, and provide comfort to any others nearby. While you concentrate on the unresponsive person, keep a mental checklist in mind: ensure airway openness, confirm breathing status, maintain a steady rhythm in compressions, and transition to defibrillation when the device is ready. Your training will help you preserve vital time and deliver life-saving care with accuracy and confidence.
The tail end of the assessment involves ensuring continuous monitoring and readiness for changes in the patient’s status. If the person begins to breathe normally, shift them to a stable recovery position while continuing to observe for irregularities. If conscious responsiveness returns at any point, reassure the individual and seek urgent medical evaluation to address the underlying cause. In all cases, maintain clear communication with responders and bystanders, documenting events and any interventions performed. Your composure and methodical approach in this moment provide a solid foundation for ongoing care until professional help takes over.
In summary, the systematic evaluation of consciousness and breathing is an essential precursor to CPR. By confirming responsiveness, assessing breathing, and acting decisively in accordance with established guidelines, lay rescuers can maximize outcomes. This process eliminates guesswork and ensures that the correct sequence—assist airway, monitor breathing, and apply chest compressions or defibrillation as appropriate—occurs without delay. Ongoing education, regular practice, and confidence-building drills help keep essential lifesaving skills sharp, enabling more people to respond effectively during emergencies and potentially save more lives.
