Foreign Body Airway Obstruction (FBAO) Management

Comprehensive vocabulary flashcards covering the recognition, assessment, and management of Foreign Body Airway Obstruction (FBAO) in adult, child, and infant populations.

Foreign-Body Airway Obstruction (FBAO)

A life-threatening medical emergency, commonly referred to as choking, resulting from the mechanical entry and blockage of foreign material in the respiratory tract.

Epidemiology of Choking Fatalities (England and Wales, $2016$)

An annual mortality count of $252$ deaths, with nearly $30\%$ occurring in adults aged $80$ years and older.

Setting of Choking Fatalities

Institutional environments where over $60\%$ of choking deaths occurred in $2016$, primarily within hospitals and residential healthcare facilities.

FBAO Mortality Significance in the Philippines

A major national healthcare statistic identifying foreign-body airway obstruction as one of the leading causes of mortality.

Clinical Opportunity for Early FBAO Intervention

The window of time during mealtimes when choking incidents are actively witnessed, enabling immediate bedside action before the patient loses consciousness.

Predominant Etiology of Adult Choking Deaths

Food substances, accounting for approximately $87\%$ of all choking-related fatalities according to the Office for National Statistics ($2017$).

Inanimate Object Choking Etiology

Small non-food items, accounting for approximately $13\%$ of fatal choking events overall and representing a significant hazard in young children.

Systemic and Neurological Risk Factors for FBAO

Predisposing conditions including altered consciousness, drug or alcohol intoxication, stroke-induced cough or swallowing impairment, respiratory diseases, dementia, cognitive impairment, and poor dentition.

Pharmacological Device Linked to FBAO

Metered Dose Inhalers (MDIs), identified as a clinical device associated with an elevated risk of foreign-body aspiration.

Universal Sign of Choking

A silent postural presentation where a victim involuntarily grasps, clutches, or points directly to their throat.

Initial Verbal Assessment for Suspected FBAO

Directly asking the patient "Are you choking?" to quickly distinguish between mild and severe airway obstruction based on their vocal response.

Mild Airway Obstruction (Adult Presentation)

A partial blockage state characterized by full responsiveness, the ability to speak or vocalize, and a forceful, effective cough.

Severe Airway Obstruction (Adult Presentation)

A critical state characterized by an ineffective or silent cough, inability to speak (often nodding "yes" silently), cyanosis, and severe respiratory distress.

Management of Adult Mild Airway Obstruction

Encouraging spontaneous, forceful coughing while maintaining continuous observation, avoiding invasive back blows or thrusts that could worsen the blockage.

Physiological Mechanism of Choking Interventions

Generating sudden elevations in intra-thoracic pressure through back blows or thrusts to forcefully expel the lodged foreign body from the airway.

Efficacy of Back Blows Alone

Relieving foreign-body airway obstruction in approximately $50\%$ of cases, while the remaining $50\%$ require complementary thrust techniques.

Adult Back Blows Technique

Standing slightly behind and to the side, supporting the chest, leaning the patient forward, and delivering up to $5$ sharp slaps between the scapulae with the heel of the hand.

Adult Abdominal Thrusts (Heimlich Maneuver)

Standing behind the patient, placing a clenched fist between the umbilicus and ribcage, clasping it with the other hand, and delivering up to $5$ sharp inward and upward thrusts.

Anatomical Danger Zone in Abdominal Thrusts

The xiphoid process and lower ribcage, which must be avoided during thrusts to prevent lacerations or traumatic rupture of internal abdominal organs.

Alternating Sequence for Conscious Adult Severe FBAO

Delivering cycles of up to $5$ back blows alternating with up to $5$ abdominal thrusts, re-evaluating the airway after each attempt until cleared.

Chest Thrusts in Obese or Pregnant Adults

A modified clearance technique positioned over the lower half of the sternum with sharp backward thrusts, utilized when abdominal encirclement is physically impossible.

Protocol for the Unconscious Adult Choking Victim

Supporting the patient safely to the floor, alerting emergency response teams, and immediately starting CPR beginning with $30$ chest compressions followed by $2$ rescue ventilations.

Visceral Complications of FBAO Procedures

Severe internal traumatic sequelae, such as laceration or rupture of thoracic or abdominal organs, requiring mandatory clinical examination after chest compressions or thrusts.

Post-FBAO Warning Symptoms

Persistent cough, difficulty swallowing (dysphagia), or the continuous feeling of a throat obstruction, signaling retained foreign material requiring urgent medical evaluation.

Guidelines on Commercial Airway Clearance Devices

Mechanical suction devices whose routine clinical use is not recommended over standard manual maneuvers or advanced endoscopic removal techniques.

Advanced Clinical Interventions for FBAO

Direct visualization and manual extraction of foreign objects using suction or laryngoscopy with Magill forceps, performed by trained healthcare personnel.

Pediatric Choking Mortality ($2014$-$2016$)

A recorded $30$ choking deaths in infants and children under $14$ years old in England and Wales, split equally ($50\%$ each) between food and inanimate items.

Pediatric Choking Prevention Strategies

Cutting food into small pieces, keeping small objects (building bricks, button batteries, coins, marbles) out of reach, enforcing seated meal times, and constant adult supervision.

Mild Airway Obstruction (Pediatric Presentation)

A child or infant who can cry or speak, produces a loud cough, can take a breath before coughing, and displays full alertness.

Severe Airway Obstruction (Pediatric Presentation)

A child or infant presenting with silence, inability to cry or vocalize, an ineffective or silent cough, stridor, cyanosis, and deteriorating consciousness.

Management of Pediatric Mild Airway Obstruction

Encouraging continuous spontaneous coughing under close observation without administering back slaps or thrusts, which could inadvertently worsen airway patency.

Infant Back Slap Technique ($<1$ Year)

Positioning the infant prone along the lap or forearm with the head tilted downward, delivering up to $5$ sharp slaps between the scapulae using the heel of one hand.

Infant Mandibular Support Precaution

Holding the infant's lower jaw at the bony angles with the thumb and fingers while avoiding compression of the submandibular soft tissues to prevent airway occlusion.

Infant Chest Thrust Technique ($<1$ Year)

Supporting the infant supine in a head-downward tilt and delivering up to $5$ sharp thrusts to the lower sternum, approximately one finger-width above the xiphisternum.

Infant Chest Thrusts vs CPR Compressions

Airway thrust maneuvers that are delivered with greater sharpness and at a slower rate than standard rhythmic chest compressions.

Conscious Infant Severe FBAO Cycle

Delivering continuous cycles of up to $5$ back slaps alternating with up to $5$ chest thrusts, checking for foreign object dislodgement after each action.

Back Slaps for Children Over $1$ Year

Positioning a smaller child head-down across the lap or leaning an older child forward, delivering up to $5$ sharp slaps between the shoulder blades.

Abdominal Thrusts for Children Over $1$ Year

Positioning behind the child (standing or kneeling), placing a clenched fist between the umbilicus and xiphisternum, and delivering up to $5$ sharp inward and upward thrusts.

Unresponsive Pediatric Choking Positioning

Carefully supporting the infant or child onto a firm, flat surface and summoning assistance immediately without abandoning the patient.

Contraindication of Blind Finger Sweeps

Probing the oral cavity or pharynx without directly visualizing the foreign object, strictly avoided because it risks forcing the obstruction further down the airway.

Protocol for Visible Objects in Unconscious Pediatric Victims

Performing a single finger sweep to remove the foreign body only when it is clearly visualized in the mouth.

Initial Ventilations in Pediatric Unconscious Choking

Opening the airway and delivering $5$ rescue breaths, assessing for chest rise and repositioning the head if ventilations fail to inflate the lungs.

Lone Rescuer Pediatric CPR Timing

Performing approximately $1$ minute of CPR on an unresponsive child or infant before pausing to summon emergency assistance.

Professional Standards for FBAO Execution

Carrying out airway clearance maneuvers only after accredited education, supervised clinical training, competency assessment, and alignment with institutional protocols.
