The correct use of aerosols
The long-term inhaled hormone approach, currently promoted by the Global Asthma Control Initiative, has been clinically proven in a large number of cases to achieve good and complete control in more than 80% of patients. However, the correct use of inhalation devices is crucial in achieving asthma control during treatment. Because inhalation therapy is a topical method of administering medication into the airways, if the medication is simply inhaled in the mouth or pharynx and all of it is spit out after gargling, not only is the medication wasted, but it will also be ineffective.
Aerosols were available in the 1970s, but many patients used them incorrectly, and some doctors who were not specialists also used them incorrectly, which affected the efficacy of the drugs.
Proper use of aerosols.
Step 1: Open the cap;
Step 2: Shake the drug well;
Step 3: Breathe out first and exhale all the air;
Step 4: then do a deep and slow inhalation, while inhaling, press the aerosol;
Step 5: Hold your breath for 10 seconds after inhaling the drug.
Step 6: Pay attention to rinse your mouth to the pharynx after inhaling the drug (to avoid side effects such as ulcers and hoarseness in the oropharynx caused by the drug remaining in the mouth)
Note: When pressing the aerosol must be synchronized with inhalation.
The correct use of aerosol plus storage fog cans.
Step 1: Open the lid;
Step 2: Shake the drug well;
Step 3: Clasp the patient’s mouth and nose with the aerosol can, and then insert the drug into the can;
Step 4: Then press the aerosol 1 to 2 times according to the doctor’s request;
Step 5: Breathe normally for more than 30 seconds;
Step 6: Pay attention to scrub the part of the mask buckled with a wet towel and rinse the mouth after inhaling the medicine.
Note: breathing should be natural, do not short and fast breathing, resulting in ineffective ventilation, drug inhalation can not be inhaled into the trachea.
This method can be used by children and adults with low PEF, or those who cannot learn to use aerosol alone, and the method of adding aerosol cans is simple and has a high rate of drug deposition in the lungs
Proper use of dry powder
According to the Global Initiative for Asthma Control (GINA), inhaled hormones are the preferred method for both acute exacerbations and remissions, and have been clinically proven to achieve good and complete control in more than 80% of our patients, if not more. However, during the course of treatment, we do find that many patients’ asthma control is compromised by incorrect inhalation methods.
Dry powder was available in the 90’s, the DuPont device in 1996, and the quasi-napper device in 2000. The advantages of dry powder are, first, the absence of a throwing agent (because some aerosol throwing agents are still Freon) and, second, the high rate of deposition in the lungs. However, there are many patients who use it incorrectly, and some doctors who are not specialists do not teach their patients to use it, leaving them to read the instructions themselves, and incorrect use also affects the efficacy of the drug.
Proper use of dry powder – DuPont (including Pulmicort, Oxy, and Cymbicort DuPont).
Step 1: Unscrew and pull out the cap;
Step 2: Take the bottle vertically and rotate the base, rotate until you can no longer rotate and return the original way, when you hear a click, it indicates that the medication has been filled;
Step 3: Exhale first, after exhaling all the air, put the mouthpiece into the mouth, wrap your lips around the mouthpiece, inhale hard and then take the device out of the mouth;
Step 4: Hold your breath for 10 seconds and then exhale slowly;
Step 5: Pay attention to rinse your mouth after aspiration.
Note: Patients with acute attacks and very low PEF (below 180’s) cannot inhale this device.
Correct use of dry powder – quasi-nasal device (sulforaphane).
Step 1: Hold the housing with one hand, place your thumb on the thumbstick with the other hand and push your thumb outward until the paracentesis is fully opened;
Step 2: Hold the quasi-napper with the mouthpiece to yourself and push the slide rod outward until it clicks, indicating that the quasi-napper is ready to absorb the drug, at which time the drug reading is reduced by one number (countdown);
Step 3: Exhale first, exhale all the air, then put the suction nozzle into the mouth and inhale the drug deeply and smoothly from the quasi-nare, then take the quasi-nare out of the mouth;
Step 4: Hold your breath for 10 seconds and then exhale slowly;
Step 5: Pay attention to rinse your mouth after inhalation.
The features of the quasi-inhaler are
Low inspiratory resistance, suitable for patients over 4 years old, sealed package with accurate counting, stable output dose, addition of lactose, and patient sensation after inhalation.
Caution.
The suction nozzle is aligned with the pharynx, the head is slightly tilted up and the airway is straightened for better inhalation;
Acute attack, the PEF is very low (below 150) patients can not inhale this device.
