First Aid for Cardiac and Hematological Emergencies
First aid interventions in community cardiac care settings can be life-saving. Community health nurses must be proficient in these skills and able to teach them to patients, families, and community members.
Cardiac Emergencies
First Aid Protocol: Suspected Heart Attack
- Call emergency services immediately (activate EMS/911)
- Help the person into a comfortable position (typically semi-reclined with knees bent)
- Loosen tight clothing
- Administer aspirin (324mg) if available and not contraindicated
- Instruct to chew for faster absorption
- Do not administer if allergic or if bleeding is a concern
- Administer nitroglycerin if prescribed and available
- Ensure BP >90mmHg if measuring equipment is available
- Do not administer if patient has taken erectile dysfunction medications within 24-48 hours
- Monitor vital signs if equipment is available
- Be prepared to perform CPR if the person becomes unresponsive and is not breathing normally
- If an AED is available, prepare to use it if needed
First Aid Protocol: Cardiac Arrest
- Confirm unresponsiveness and absence of normal breathing
- Call emergency services immediately or have someone else call
- Begin high-quality CPR:
- Place person on firm, flat surface
- Position hands in center of chest (lower half of sternum)
- Deliver compressions at rate of 100-120 per minute
- Compress chest at least 2 inches (5 cm) deep
- Allow complete chest recoil between compressions
- Minimize interruptions in compressions
- If trained in CPR with ventilations, use 30:2 compression-to-ventilation ratio
- Apply AED as soon as available:
- Turn on the AED
- Attach pads to bare chest as shown in diagram
- Allow AED to analyze rhythm
- Ensure no one is touching patient during analysis
- Deliver shock if advised, ensuring no one is touching patient
- Resume CPR immediately after shock or if no shock advised
- Continue CPR until emergency services arrive or the person shows signs of life
Bleeding Emergencies
First Aid Protocol: Severe External Bleeding
- Apply direct pressure to the wound using clean cloth, gauze, or clothing
- If blood soaks through, add more material without removing the original dressing
- Elevate the bleeding extremity above the level of the heart if possible
- If bleeding continues uncontrolled and involves an extremity, apply tourniquet if available and trained to do so:
- Place 2-3 inches above wound but not on a joint
- Tighten until bleeding stops
- Note time of application
- For wounds to torso or areas where tourniquets cannot be applied, consider wound packing with gauze if trained
- Seek emergency medical care immediately
First Aid Protocol: Nosebleed
- Have the person sit upright and lean slightly forward
- Apply firm pressure to the soft part of the nose below the nasal bone:
- Pinch nostrils together with thumb and index finger
- Maintain continuous pressure for 10-15 minutes
- Apply cold compress to bridge of nose
- Instruct person to breathe through mouth and avoid:
- Swallowing blood (can cause nausea)
- Speaking, sniffing, or blowing nose
- Inserting tissues into nostrils
- If bleeding persists beyond 20 minutes or is severe, seek medical attention
- For patients on anticoagulants or with bleeding disorders, seek medical attention more promptly
Community cardiac care Education Tip: Include first aid skills training in community health events and patient education sessions. Ensure that high-risk patients and their family members are trained in basic CPR and first aid for bleeding. Consider organizing CPR certification events in community settings.
