Eat Slower, Stay Safer: A Guide to Mealtime Safety for Alzheimer's Patients

Family members caring for a loved one with Alzheimer's disease (AD), please pay close attention. Due to declining cognitive function, reduced ability to perform daily activities, behavioral and psychological symptoms, and the effects of medications, AD patients are prone to swallowing difficulties. This can lead to aspiration or choking during meals, which is extremely dangerous. Do not take this lightly.

I. What Are Aspiration and Choking?

1. Aspiration
Simply put, aspiration occurs when substances that should go into the stomach—such as stomach contents, nasopharyngeal secretions, or saliva—accidentally enter the airway below the vocal cords, either during eating or at other times.
Aspiration can be overt (obvious signs) or silent (no immediate symptoms, but equally dangerous).

2. Choking
Choking happens during a meal when a person suddenly cannot speak, shows signs of extreme distress or a suffocating expression, has difficulty breathing, clutches at the throat, coughs violently with wheezing sounds between coughs. In severe cases, they may collapse, become confused, or agitated.[1]

II. Watch for These Risk Factors in the Patient

1. Medical Conditions
If the patient has dysphagia (trouble swallowing), gastroesophageal reflux (acid or food backing up), a weak cough reflex (inability to clear foreign material), oral problems such as poor teeth or mouth sores, or cerebrovascular disease, these all increase the risk of aspiration and choking.

2. Cognitive Impairments
AD patients often have reduced attention, executive function, and memory. They may be unable to concentrate during meals or may not know how to eat properly, which also raises risk.

3. Medications
If the patient is taking antipsychotics or sedatives, these drugs can affect swallowing function, increasing the likelihood of aspiration and choking.

4. Eating Habits
Pay special attention if the patient eats while lying flat (poor posture), has reduced selffeeding ability, eats too quickly (gulping food), accidentally consumes inappropriate items, becomes agitated or behaves abnormally during meals, refuses to eat, or has a history of choking or coughing while eating.

III. Daily Care Strategies

(A) Warning Reminders
Place a "Beware of Aspiration" sign at the patient's bedside so that both healthcare workers and family members are constantly reminded to ensure mealtime safety.

(B) Careful Supervision During Meals

1.Eating environment: Keep it quiet, pleasant, and welllit. Avoid distractions.

2.Positioning: Have the patient sit upright or in a semireclined position. For those who are bedridden or unable to sit up straight, place them in a supine position with the head of the bed raised 3040 degrees. Keep this position for 30 minutes after the meal.

3.Utensils:

Spoons: Choose shallow, smallbowl spoons with long handles. For patients with weak grip, use utensils with thick, easytohold handles.

Bowls: Use bowls or plates that are wide, shallow, and have a flat rim. If needed, place a nonslip mat under the bowl.

Cups: Use cups with a cutout rim or cups with a straw.

4.Prepare assistive devices: Dentures, glasses, hearing aids, etc.

5.Food preparation: Foods should be soft, finely chopped, and wellcooked. If necessary, add thickeners to liquids or puree solid foods. Serve solid and liquid foods separately. Remove foods that are too hot or likely to cause choking.

6.Meal duration: Aim for 3040 minutes per meal. Never rush the patient. Divide food into small portions and serve them one at a time, especially for patients who eat too quickly.

7.Bite size: Start with a small amount (24 ml per bite) and gradually increase, but never exceed 20 ml per bite. Wait until the patient has swallowed completely before offering the next bite.

8.For patients with dysphagia: Assist them with techniques such as lateral swallowing, dry swallowing, alternating swallowing, effortful swallowing, headnodding swallowing, and chindown swallowing to adjust head posture and the act of swallowing.

9.For those with reduced selffeeding ability: Gently press the upper lip and jaw, and use verbal cues and demonstrations to guide the patient to chew.

10.Oral hygiene: After the meal, check the patient's mouth. Instruct them to dryswallow several times to clear any residual food. If needed, help remove leftover food manually.

(C) Swallowing and Feeding Training
Engage the patient in daily swallowing exercises and rehabilitation training, such as spaced retrieval training and Montessoribased activities. These methods are very helpful for improving the patient's feeding ability, but they must be carried out under the guidance of a professional.

IV. What to Do If Aspiration Occurs

Even when it is not mealtime, if you notice the patient making chewing movements, check their mouth immediately for any foreign object. During meals, continuously observe the patient's facial expression and skin color. If you suspect aspiration or choking, take emergency action at once.

If aspiration occurs, rescue the patient on the spot without delay. Immediately and effectively clear food from the mouth and pharynx to open the airway, while notifying a doctor.

Use the "Scoop and Position" method:

Scoop: Use your middle and index fingers or a clamp to scoop out the foreign object from the patient's mouth.

Position: Have the patient turned upside down (with a doctor's assistance), and strike their back with your palm. Vibration may loosen the food, moving it toward the throat to be coughed out.

If this fails, immediately apply the Heimlich maneuver (abdominal thrusts): Stand behind the patient with one leg forward, placing a foot between the patient's feet. Have the patient sit on your bent thigh, leaning slightly forward with head down and mouth open. Wrap your arms around the patient's waist. Make a fist with one hand and place the thumb side against the patient's upper abdomen, above the navel and below the ribcage. Grasp your fist with your other hand. Deliver rapid, upward, inward thrusts to the upper abdomen at a rate of about one per second. Repeat until the object is expelled or the patient starts breathing.

If the choking is not relieved, follow the doctor's orders for further management (e.g., cricothyroid membrane puncture) until the airway is clear. You can also design an emergency plan for your home and practice it regularly, so you won't panic when a real emergency arises.
