Asfixia can ou gato: mascota manobra de Heimlich e RCP animal¶

Ver ao teu can ou gato de súpeto darlle unha pata violenta á boca, amordazar en silencio cos ollos ben asustados, volverse gris-azul nas enxivas e na lingua (cianose) e colapsarse cunha pelota hinchable de goma, masticar coiro cru, fragmento óseo ou corda encaixada na súa gorxa é unha terrible crise doméstica na que ocorre a morte cerebral en 6 minutos**. A diferenza das emerxencias humanas nas que chamar ao 911 envía aos paramédicos á súa sala de estar en minutos, os equipos de ambulancias municipais na maioría das xurisdicións non responden ás chamadas veterinarias (aínda que sempre debe consultar números de emerxencia se un humano é mordido ou ferido durante o rescate). Vostede é o paramédico da súa mascota. Salvar un can ou gato que se asfixia ou sen pulso require distinguir inmediatamente a verdadeira obstrución das vías respiratorias das condicións non asfixiantes, como tos de canela ou espirros inversos, utilizando a técnica Empuxe da garganta externa ("J-Stroke") cando unha bola lisa queda atrapada na farinxe, realizando estornudos dorsales e túbulos específicos.

1. Confirm whether the pet can still breathe, cough forcefully, or bark/meow before putting your fingers near their mouth. If your dog or cat is coughing loudly, gagging while moving air in and out, and has pink gums, it is a partial obstruction: do NOT stick your fingers into a panicked, conscious pet's mouth (they will bite down with bone-crushing force in sheer terror). Keep them calm and rush them immediately to the nearest 24-hour emergency veterinary hospital. If the pet cannot make a sound, has high-pitched whistling (stridor) or silent chest heaving, or has blue/gray/white gums, it is a complete airway obstruction: act on Steps 2 through 6 right now.
2. Open the mouth with two hands and look inside ONLY if you can pull the tongue forward or use a tool. Grasp the upper jaw over the muzzle with one hand (pressing the upper lips slightly over the upper teeth as a buffer) and pull the lower jaw and tongue forward with the other hand to illuminate the back of the throat. If you see a stick, rawhide strip, or bone wedged across the palate or pharynx, sweep it out using needle-nose pliers, barbecue tongs, salad tongs, or a hooked finger along the cheek wall, never push blindly straight down the center of the throat, which rams a round ball tighter into the windpipe.
3. FOR A SMOOTH RUBBER BALL OR ROUND TOY IN A DOG'S THROAT: Use the External "Throat-Push / J-Stroke" Technique. Smooth rubber balls (Chuckit balls, lacrosse balls, golf balls, tennis balls) get sucked into the funnel of the larynx and cannot be gripped by wet fingers from the front. Lay the dog on their back (or straddle them), feel on the outside underside of the neck for the hard bulge of the ball just behind the jaw/throatlatch, place both thumbs behind (closer to the chest than) the ball, and push firmly upward and forward toward the mouth in a J-motion to pop the ball out like a cork.
4. Perform 5 Sharp Back Blows in the "Wheelbarrow" or "Gravity-Inverted" Position. For a small dog or cat (under 10 kg / 22 lbs), hold the pet against your chest or over your forearm with their head angled downward toward the floor (or carefully support their pelvis/hind legs upside-down like a pendulum for 5 seconds) and deliver 5 firm, sharp heel-of-hand blows between the shoulder blades. For a medium or large dog, grab their hind legs at the hips like a wheelbarrow so their head and front paws angle down toward the floor, and deliver 5 sharp blows between the shoulder blades.
5. Perform 5 Abdominal Thrusts (The Pet Heimlich Maneuver).
6. Standing Large/Medium Dog: Stand or kneel behind the dog, wrap your arms around their waist just behind the last rib (in the soft hollow of the abdomen), make a fist with one hand covered by your other hand, and give 5 quick, firm thrusts UPWARD and FORWARD toward the spine and head (toward the diaphragm).
7. Small Dog or Cat: Hold the pet's back against your chest, place two or three fingers (or one fist) in the soft hollow just behind the ribcage, and press 5 quick thrusts inward and upward toward your own chest/their head. Check the mouth after every 5 thrusts and clear any dislodged object.
8. If the pet collapses unconscious and stops breathing, sweep the throat deeply and start Veterinary CPR (30 Compressions : 2 Rescue Breaths). Once a pet goes completely limp and unconscious, their jaw muscles relax completely: open the jaws wide, pull the tongue all the way forward out of the mouth, reach deep into the pharynx with your fingers or pliers to yank out the foreign object, and immediately begin 30 chest compressions (at 100 to 120 per minute, compressing ⅓ to ½ of chest width) followed by 2 Mouth-to-Snout Rescue Breaths while someone drives you to the emergency vet.

Phase 1: Is your pet actually choking? Ruling out "Look-Alike" conditions¶

Before performing aggressive abdominal thrusts (which can bruise the liver, rupture a full stomach, or crack floating ribs if done unnecessarily), spend 5 seconds confirming your dog or cat is experiencing a true mechanical foreign-body airway obstruction rather than one of four common veterinary look-alikes:

Phase 2: Step-by-step choking clearing techniques by pet size and object type¶

Technique 1: The External Throat-Push ("External J-Stroke") for Balls and Smooth Objects¶

Developed and taught by emergency veterinarians specifically for ball-choking dogs, this maneuver bypasses the teeth and works even on a thrashing or unconscious dog:

1. Position the dog on their back (dorsal recumbency) on the floor, wedging their spine between your knees so they cannot roll over, with their head pointing away from you (or toward you if easier to reach the neck).
2. Locate the wedged ball from the outside of the neck: Feel with both hands along the underside of the throat where the larynx (voice box / Adam's apple) meets the base of the skull and jaw bones. You will feel a rock-hard, spherical bulge where the ball is lodged inside the pharynx.
3. Lock both thumbs BEHIND the ball (on the chest side of the bulge): Place your fingers around the sides of the dog's neck/jaw for leverage, and press both thumbs deeply into the soft tissue of the neck immediately behind (caudal to) the trapped ball, between the ball and the chest.
4. Conduce a pelota con forza cara adiante e cara arriba ("J-Stroke"): Empurra con forza cos dous polgares cara ao nariz do can e cara arriba cara ao teito. Isto apreta a estreita traquea/farinxe detrás da bóla e fai estalar a bóla sobre a base da lingua e fóra a través dos dentes como espremer unha semente de sandía.

Técnica 2: extracción intraoral segura (ósos, coiro bruto, xoguetes e corda de gato)¶

If the object is irregular (a chewed rawhide knot, a bully stick stub, a chicken bone, a piece of steak fat, or a ribbon/string in a cat):

1. Use a Mouth Gag or Lip-Fold to protect your hands: If the pet is still semi-conscious, hold the upper jaw with your non-dominant hand and curl the pet's upper lips inward over the sharp premolar teeth so if they bite down, they pinch their own lip first and open up. Alternatively, slide a thick rolled-up towel or wooden spoon handle sideways between the back molars as a temporary bite block.
2. Pull the Tongue Forward: Grab the tip of the pet's tongue (using a dry washcloth or paper towel for grip on a slippery tongue) and pull it straight forward out between the front incisor teeth. Pulling the tongue forward physically pulls the epiglottis and larynx forward, opening the back of the throat by 2 to 3 centimeters and often freeing objects trapped at the epiglottis automatically.
3. Extract with Long-Nose Tongs, Pliers, or a Hooked Finger Sweep:
4. If you have kitchen tongs, salad tongs, or needle-nose pliers within arm's reach, use them to clamp onto the rawhide, bone, or toy and pull straight out.
5. If using your finger, slide your index finger down the inside wall of the cheek (outside the teeth until you reach the very back behind the last molar), hook your fingertip behind the object, and sweep it forward.
6. Cat Linear Foreign Body Warning: If a cat is gagging on a piece of yarn, sewing thread, tinsel, or ribbon and you see the string wrapped around the base of the tongue, gently unloop it from the base of the tongue if loose, but NEVER yank forcefully on a string extending down into the esophagus or stomach, if the other end is anchored in the intestines, pulling it slices through the esophagus and bowel like a cheese wire. Cut away any loose external string only if it is not blocking the windpipe and rush to the vet.

Technique 3: Gravity Inversion + 5 Back Blows + 5 Abdominal Thrusts (The Pet Heimlich)¶

If the object cannot be seen or popped out externally, alternate 5 Back Blows and 5 Abdominal Thrusts continuously:

Phase 3: Official RECOVER Veterinary CPR (When a dog or cat stops breathing)¶

If a choking pet loses consciousness, or if you find your dog or cat collapsed from drowning, electric shock, smoke inhalation, poisoning, or cardiac arrest, follow the international RECOVER (Reassessment Campaign on Veterinary Resuscitation) guidelines developed by the American College of Veterinary Emergency and Critical Care (ACVECC) and the Veterinary Emergency and Critical Care Society (VECCS).

Step 1: The 10-Second Airway & Breathing Check (Skip the Pulse Check.)¶

Just as in modern human CPR, RECOVER guidelines instruct pet owners NOT to waste 30 seconds feeling around for a femoral artery pulse in the groin or listening for a faint heartbeat. Untrained owners frequently mistake their own thumb pulse for the dog's pulse, wasting fatal seconds.

1. Call the pet's name and tap their shoulder/paw.
2. Look at the chest and open the mouth to check for normal breathing (ignoring occasional terminal gasps / agonal breaths).
3. If the pet is unresponsive and NOT breathing normally: Sweep the throat deeply one final time for any foreign object, pull the tongue forward, close the snout, and start 30 Chest Compressions + 2 Mouth-to-Snout Rescue Breaths immediately.

Step 2: Exact Hand Placement and Chest Shape Guide for Canine & Feline CPR¶

Unlike humans (who all have flat front-to-back chests and undergo CPR lying on their backs), dogs and cats have four different chest geometries and almost always receive CPR lying on their side (lateral recumbency):

========================================================================
RECOVER VETERINARY CPR HAND PLACEMENT BY BREAST / CHEST SHAPE
========================================================================
1. MOST MEDIUM, LARGE & GIANT ROUND-CHESTED DOGS (Labradors, Goldens,
   Shepherds, Rottweilers):
   * Position: Lay dog on their RIGHT or LEFT SIDE on a hard flat floor.
   * Hand Placement: Place both hands stacked (fingers interlocked, elbows
     locked straight) over the WIDEST, HIGHEST dome of the ribcage (NOT
     directly over the heart). Compressing the widest part of the chest
     uses the "Thoracic Pump" mechanism to squeeze blood out of the entire
     chest cavity.

2. DEEP, NARROW "KEEL-CHESTED" DOGS (Greyhounds, Whippets, Dobermans,
   German Shorthaired Pointers, Afghan Hounds):
   * Position: Lay dog on their SIDE.
   * Hand Placement: Place both stacked hands DIRECTLY OVER THE HEART
     (at the 4th to 6th intercostal space, exact spot where the front
     elbow touches the chest wall when pulled slightly back). This uses
     the "Cardiac Pump" mechanism to squeeze the heart ventricles directly
     between the left and right ribs.

3. FLAT-CHESTED / BARREL-CHESTED BRACHYCEPHALIC DOGS (English Bulldogs,
   French Bulldogs, Pugs, Boston Terriers):
   * Position: Roll the dog onto their BACK (Dorsal Recumbency, just like
     a human.) braced between knees or pillows.
   * Hand Placement: Place hands directly on the midline of the STERNUM
     (breastbone) over the heart and compress straight down toward the floor.

4. CATS & TINY TOY DOGS (Under 7 kg / 15 lbs ,  Cats, Chihuahuas, Yorkies):
   * Position: Lay pet on their SIDE.
   * Hand Placement (One-Hand Circumferential Cardiac Pump): Wrap your
     dominant hand around the bottom of the sternum (breastbone) directly
     over the heart (where the bent elbow meets the ribcage) so your
     THUMB is on one side of the chest and your FINGERS are on the other
     side, squeezing the heart between your thumb and fingers. (Or use
     two-handed heel-of-hand over the heart if your hand fatigues).
========================================================================

Step 3: Compression Rate, Depth, and the 30:2 Rescue Breath Cycle¶

1. Compression Rate: Push hard and fast at 100 to 120 compressions per minute (to the beat of the song "Stayin' Alive", nearly 2 compressions every second).
2. Compression Depth: Compress the chest by one-third to one-half (⅓ to ½) of the total width of the pet's chest on every push. Allow the chest wall to recoil 100% completely back to its normal height between compressions so the heart can refill with blood (do not lean on the chest at the top of the stroke).
3. Delivering 2 Mouth-to-Snout Rescue Breaths (Every 30 Compressions):
4. Unlike healthy human adults who collapse from sudden cardiac arrhythmias with oxygen still in their blood, over 90% of dogs and cats in arrest suffer from asphyxial arrest (choking, hypoxia, respiratory failure), meaning Mouth-to-Snout Rescue Breaths are essential.
5. How to give a Mouth-to-Snout Breath:
   1. Pull the pet's tongue slightly forward so it does not block the throat, then close the pet's jaws tightly shut and wrap both of your hands completely around the muzzle to seal the lips so air cannot leak out the sides of the mouth.
   2. Extend the pet's head and neck into a straight line with their spine (do not flex the chin down to the chest; straighten the neck to open the windpipe).
   3. Place your wide-open mouth completely over both of the pet's nostrils (for a medium/large dog, seal your lips around the nose; for a cat or tiny dog, your mouth will cover their entire nose and closed muzzle tip).
   4. Blow a steady 1-second breath into the nostrils while watching the pet's chest out of the corner of your eye. Blow just enough air to make the chest visibly rise (full adult lung breath for a 40 kg Shepherd; a tiny cheek-puff of air for a 4 kg cat or Chihuahua so you do not overinflate and rupture small lungs).
   5. Lift your mouth away for 1 second to let the chest fall, give a second 1-second breath, and immediately resume 30 chest compressions within 5 seconds.
6. Rotate Rescuers Every 2 Minutes: Every 2 minutes (after roughly 5 cycles of 30:2), quickly check for spontaneous breathing or movement for no more than 5 seconds, swap compressors if a second person is present to prevent fatigue, and continue CPR right into the lobby of the veterinary ER.

Phase 4: Mandatory emergency veterinary follow-up after a choking rescue¶

Even if you pop the rubber ball or bone out of your dog's throat in your kitchen and your dog stands up wagging their tail and breathing normally, you must still take your pet to an emergency veterinarian immediately. Two silent, delayed killers strike dogs and cats 2 to 24 hours after a survived choking event:

1. Non-Cardiogenic Pulmonary Edema (Post-Obstructive Flash Lung Fluid): When a dog or cat gasps violently against a blocked windpipe for 60 to 120 seconds, their diaphragm generates extreme negative vacuum pressure inside the chest cavity. That negative vacuum physically sucks fluid out of the pulmonary capillaries directly into the air sacs (alveoli) of the lungs. Up to 2 to 12 hours after the ball is removed, the dog's lungs can slowly fill with pink frothy fluid, causing sudden respiratory failure unless treated early with veterinary oxygen therapy and monitoring.
2. Delayed Laryngeal Edema and Mucosal Lacerations: Sharp bones, sticks, or forceful extraction can bruise or tear the delicate mucosa of the larynx and epiglottis, causing progressive inflammatory swelling that narrows the airway hours later, or creating a microscopic esophageal perforation that leads to lethal chest infection (mediastinitis / pyothorax) within days.
