Direct inhalation is suitable for relatively large children, adolescents and adults
The final destination of the drug particles in the aerosol is the patient’s lungs, but not aerosol randomly sprayed into the mouth, the drug particles will obediently run to the lungs, how to make the drug particles are well sucked into the lungs, to maximize the therapeutic effect?
Step 1: Remove the cap of the aerosol, pinch the thumb on the lower end of the finger, pinch the middle finger on the upper end, hold the middle part of the medicine tool between the index finger and ring finger, and shake the aerosol bottle up and down hard and fast for 3~4 times to make the medicine in the bottle evenly mixed. This is done because many aerosols are two-phase aerosols, i.e.: solution-type aerosols, so shaking up and down well is a very critical step.
Common mistakes: holding a variety of postures, some easy to slip off, some are not conducive to stimulate the drug, some are not conducive to drug inhalation, bring it with never shake the solution quickly and forcefully, you can see a large percentage of people who forget to do so in the clinic.
Step 2: Do 2 slow deep inhalation and deep exhalation exercises. The purpose of doing this is to prepare for the inhalation of the medicine, after the lungs are fully ventilated can do a good job of closing the air after inhaling the medicine, the longer the time of closing the air, the more the drug stays in the lungs. Many people feel that most of the reasons for not being able to breathe in when they inhale is that they do not exhale as much gas as possible from their lungs. It is important to understand that the deeper the inhalation the deeper the drug reaches the lungs, the better the effect of improving small airway obstruction, and the more the treatment cost is saved.
Breathing essentials.
1, only use the mouth to inhale, do not have the nose at the same time to inhale, if you do not cooperate well, you can practice with hands pinching the nose.
2, inhalation upper and lower incisors to open 2cm, lips contracted into a circle, tongue flattened or concave in the mouth, tongue tip do not roll up, tongue surface do not top up, gently against the root of the lower incisors, the mouth to have a hollow, do not be filled with tongue.
3, each inhalation time in 3 to 5 seconds, the requirement to do a slow, even and long continuous inhalation, slowly fill the lungs, and then slowly exhale the lung gas with force, and strive to exhale the last bit of gas in the lungs, the exhalation time lasts more than 3 seconds (exhalation for one second is simply impossible to exhale the residual gas clean, the more residual gas in the lungs, the worse the effect of drug use).
4, until you can no longer exhale, then do the exercise a second time.
Step 3: Inhalation of drugs (Pulmicort aerosol, co-cortisone aerosol and Ventolin, Asthmacontrol, Boliconi, Albuterol and other common aerosol forms)
Inhalation techniques.
1, after preparing for breathing, head upright, body upright, flat end of the inhalation device, nozzle in the lower, with the mouth containing the inhaler, lips tightly wrapped around the nozzle.
2, the upper and lower teeth should be open to bite the nozzle, there is space in the mouth, the tongue should be flat or concave, the tip of the tongue gently against the root of the lower incisors (do not top at the nozzle, the tongue should not be arched, so that the drug is sprayed on the tongue), first exhale, the residual air in the lungs again exhale with full force, exhale all the while one hand pinching the nose (this is in order not to nose involved in inhalation, if you can Sensor nose inhalation, after skilled can not pinch the nose).
3, the other hand finger forcefully and quickly press the inhaler once to issue the drug (press when the aerosol must be nozzle in the down vertical state, do not trigger twice in a row, that is a waste, to feel the gas ejected directly in the throat is best, if it hits the tongue surface, to adjust the shape of the tongue, the tongue surface down concave is best, the next inhalation fine-tune the nozzle angle to find the right position).
4, while doing a slow, even and long continuous inhalation, only use the mouth to slowly inhale the drug, keep the entire inhalation action process handheld action and mouth shape and drug position unchanged, do not move, only the inhalation action of the lungs, inhalation time lasts 3 to 5 seconds, do not inhale very quickly, to inhale at an even rate, many people suck fast to stop halfway through the inhalation, not really inhale the drug to the bottom of the lungs, remember that Inhale while the lips do not leave the mouth of the spray, to wrap tightly, to breathe in from the mouth of the spray.
Many people commonly in the wrong action when spraying drugs are as follows.
(1) open mouth spray, do not wrap the nozzle tightly, resulting in a large amount of drug waste, and open wide mouth inhalation of drugs will allow the drug to reach only the large airways, can not reach the small airways, so that inhalation is simply ineffective.
(2) after spraying the lips leave the nozzle, there will be smoke dispersed in the mouth, and then shut up and inhale, which is wrong, inhale through the nose, the drug in the mouth, the nose is not sucked in, and finally the drug is swallowed into the stomach, simply ineffective.
(3) inhalation and spraying is not synchronized, it is common to inhale to half before triggering the spraying, resulting in excessive inflation in the lungs, the drug inhalation can not reach the deep lungs of the tiny bronchi, just fell to the large airways, the effect is very poor. (2) If the drug is sprayed first and then inhaled, the drug airflow is very fast and repeatedly shocked in the mouth, which will cause a large amount of adhesion of the drug in the oral mucosa and reduce the amount of drug entering the lungs.
(4) Inhale the drug into the lungs, hold your breath at the end of a deep inhalation, and try to hold your breath for 10 seconds, at least 5 seconds or more (exhalation within three seconds is basically ineffective inhalation) and then breathe normally. You can use the finger counting method to count from 1 to 10 fingers to end the breath closure.
Smoke-like drugs take time to fall on the airway to complete, many people inhale superficially and exhale immediately after a second or two after inhaling the drug, spitting out the drug just inhaled again, just like smoking, which is ineffective. The whole action of inhaling the drug and closing the breath is somewhat similar to the action of smoking opium often seen in movies, do not let a trace of the smoky drug go to waste, all inhaled into the lungs, deposited on the walls of the tiny bronchi in the lungs, try to reduce the drug content in the exhaled gas, at least to reach the exhaled gas can not see the smoke.
5, do a good job of gargling, brushing teeth, plus drinking and swallowing action after using the drug. Gargle as much as possible to the throat, gradually learn to tilt your head and gargle, then spit out the mouthwash, do not swallow, then brush your teeth and drink water to remove the residual oral and throat drugs as much as possible to prevent oral fungal infections and vocal cord hoarseness occur.
6, if you need to inhale the medication again, repeat 3 or 4 actions, with an interval of several minutes.
