🩺
📒 The 1-minute cheat sheet
🩺 Assess
Universal sign = hands to throat
Partial = let cough, encourage
✅ Do
Complete → Heimlich/abd thrusts
Infant: 5 back blows + 5 chest
Unconscious → start CPR
🩺 Signs
No air, cyanosis, silence
Pregnant/obese → chest thrusts
📌 Avoid
Blind finger sweep
Back slaps if can cough
📚 Choking and Airway Obstruction — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Airway obstruction occurs when a foreign object blocks the airway, preventing air exchange and causing rapid hypoxia. A complete obstruction is a true emergency requiring immediate abdominal thrusts. The priority is restoring a patent airway because oxygenation is the most basic survival need.
🔑
Key points
Understand these first
A patient with a partial obstruction who can cough forcefully is encouraged to keep coughing and is not interrupted.
Complete obstruction is marked by the universal choking sign, inability to speak, silent cough, and cyanosis.
Abdominal thrusts (Heimlich maneuver) are used for conscious choking adults and children over 1 year.
Infants under 1 year receive 5 back blows followed by 5 chest thrusts, never abdominal thrusts.
If the patient becomes unresponsive, lower them to the floor and begin CPR, checking the mouth for the object before breaths.
Chest thrusts replace abdominal thrusts in pregnant or obese patients.
✅
Nursing priorities
What to do, in order
Assess whether the cough is effective; encourage coughing if air exchange is present.
Deliver abdominal thrusts for a conscious adult with complete obstruction until the object clears.
Begin CPR if the patient becomes unresponsive and check for a visible object before each set of breaths.
Give high-flow oxygen and reassess airway patency once the object is removed.
Anticipate the need for suction, laryngoscopy, or emergency cricothyrotomy if obstruction persists.
🚩
Red flags — report now
Escalate immediately
A silent cough, inability to speak, or cyanosis indicates complete obstruction - intervene now.
Never perform blind finger sweeps, as they can push the object deeper.
Never use abdominal thrusts on an infant under 1 year.
Report stridor or worsening respiratory distress immediately.
🗣️
Patient teaching
What patients must know
Cut food into small pieces, chew thoroughly, and avoid talking or laughing while eating.
Keep small objects, balloons, and hard foods like grapes and nuts away from young children.
Learn to recognize the universal choking sign and how to perform abdominal thrusts.
