気管の分岐、気管支に影響を与える条件の吸入薬が処方され、気道が徐々 に小さい細気管支が肺組織全体に 。これらの条件は、急性分類できる(すなわち、クイックで発症した、一時的な) または慢性 (すなわち、永続的なおよび/または再発症状不変の月への年)。吸入薬を必要とする一般的な急性期病棟は、急性気管支炎、肺炎、結核、肺浮腫、急性呼吸窮迫症候群に含まれます。吸入薬を必要とする慢性疾患にはその他の慢性疾患、嚢胞性線維症、肺がん、じん肺などだけでなく、COPD (すなわち喘息、慢性気管支炎、肺気腫) として分類されるそれらが含まれます。
これらの条件は、気道を開き、気道炎症を減らし、空気の流れを促進する薬が必要です。気道に直接薬の配信は薬を全身投与と比較してより高速な応答が可能し、全身性副作用の影響を低減します。吸入薬には、異なった形態および配信デバイスがあります。一般的な吸入薬には、短いと長時間作用型気管支拡張剤とステロイドが含まれます。これらは、メーター用量吸入器、ドライ パウダー吸入器、吸入器の呼吸活性化などの吸入配信デバイスのさまざまな種類を使用して配信する可能性があります。これらのデバイスには、化学推進体、深く吸入薬を提供する細かい霧のいずれかが必要です。配信の種類に関係なく、目標は同じです: 下の気管支、細気管支に薬を提供します。これらメーター用量吸入器と下気道に薬を吸い込むことの難しさを持っているを使用して、デバイスから薬リリースで座標の呼吸を助けるためスペーサーと呼ばれるデバイスを使用可能性があります。
これらの薬は、呼吸サイクルと連動管理を必要とするため、薬物を投与する前に、初め吸入薬剤投与前にプロセスの作業の理解を持っている患者のための手順について患者を教育することが重要です。徹底した呼吸の評価は、薬と配信デバイスと管理手順を遵守する能力の適正を確保するため吸入薬を管理する前に完了する必要があります。
このデモは準備と配信デバイスのプロトタイプとしてメーター用量吸入器を使用して吸入薬の管理を紹介します。
This demonstration provides instructions on the administration of inhaled medications using a metered-dose inhaler, with mouthpiece and spacer variations. For effective inhaled medication administration, it is important for the patient to be able to follow the instructions and to have adequate respiratory functioning to allow for a full, complete inhalation. If the patient is unable to coordinate the inhalation with depression of the inhaler canister, using a spacer can help to increase the likelihood of the patient receiving the full medication dose. Proper training by medical professionals will promote proper patient use and effective airway management. It is important to instruct the patient to keep the inhaler at room temperature; if it drops below room temperature, it should be warmed only with the hands prior to use to promote the effectiveness of the chemical propellant. The device should never be warmed with anything other than hands, nor should it be punctured (to avoid injury). It is important that the patient is instructed on the proper cleaning of the inhaler. To do this, the patient should remove the medication canister from the inhaler holder and mouthpiece. The inhaler and cap should be rinsed with warm water and dried completely before recombining the inhaler components. Common errors with the administration of inhaled medications include performing poor breath/dose administration coordination, failing to hold the breath at the top of inhalation for a long enough duration, breathing in too quickly to receive the full dose, failing to shake the inhaler adequately, inhaling through the nose instead of the mouth, and failing to allow sufficient time between medication doses.
Inhaled medications open airways, decrease inflammation, promote airflow, and can lead to a quicker response with reduced systemic side effects. These medications are prescribed for conditions affecting bronchi, which are the small airways that branch off the trachea and bronchioles and spread through the lung tissue.
Conditions treated with the help of inhaled medications may be acute or chronic in nature. Common acute conditions include acute bronchitis, pneumonia, tuberculosis, pulmonary edema, and acute respiratory distress syndrome. Chronic conditions include asthma, chronic bronchitis, emphysema, cystic fibrosis, lung cancer, and pneumoconiosis.
Inhaled medications are available in different forms and delivery devices. These forms include short- and long-acting bronchodilators and corticosteroids. Some patients will benefit from the use of a spacer with a metered dose inhaler to assist in coordinating breathing with the medication.
This video illustrates the preparation and administration of inhaled medications using a metered dose inhaler for treatment of acute and chronic conditions that affect the airways.
Upon entering the room, wash hands with soap or apply hand sanitizer with friction for at least 20 seconds.
At the bedside computer, logs into the patient’s electronic health record to review their medical history and past administration times. Verify with the patient any medication allergies and discuss the physical allergic responses and reactions. In the MAR, review the inhaled medications that are due to be administered and clarify with the patient if they have a preference or concerns with regard to administration.
Next, assess the patient’s respiratory status by auscultating the breath sounds and rate to determine appropriateness of medication delivery. If the patient is experiencing shallow respirations or increased work of breathing, do not forget to notify the care provider.
Review the medication administration process with the patient. Because these medications require administration that is coordinated with the breathing cycle, it is important to educate the patient about the procedure prior to administering the medication and for the patient to have a working understanding of the process before beginning inhaled medication administration. This is also an opportunity to determine if the patient needs additional education on the medication, delivery device, and/or effect on the body.
Now, leave the room and wash hands, as previously described. Then go to the medication preparation area to obtain the medication and complete the first safety check, adhering to the five “rights” of medication administration. Verify the expiration date and complete the second safety check, following the five “rights.” After the second safety check, gather the needed supplies, including a cup of water, basin, and a spacer if necessary, and go to the patient’s room.
Now, with the medications and supplies, enter the patient’s room and perform hand hygiene, as described previously. Then, complete the third and final safety check, following the five “rights.”
As with any medication administration, review the purpose of the medication with the patient, possible adverse reactions, and how it will be administered. Help the patient to an upright position to facilitate lung expansion. Now, vigorously shake the inhaler and then remove the mouthpiece cover.
Next, have the patient hold the lower portion of the inhaler between their thumb and middle finger. The index or middle finger should be placed at the top of the canister. Finally, have the patient place the mouthpiece of the inhaler between the upper and lower lips and close them tight.
Now, instruct the patient to inhale deeply and fully while depressing the canister with their index or middle finger to release the medication. At the top of the patient’s inhalation, ask them to hold their breath for 10 seconds, or as long as it is comfortable, and to release their finger from the top of the canister. If a second inhaled dose is ordered, have the patient wait for approximately 1 minute prior to administering the second dose. Ask them to follow the same steps as for the first dose.
Some patients will use a spacer to help administer the inhaled medication. This is the case when a patient has difficulty with coordinating inhalation and pressing on the canister. If using a spacer, first shake the inhaler with vigor and remove the mouth piece cover. Next, while holding the inhaler near the bottom with your non-dominant hand, and the spacer in your dominant hand, insert the mouthpiece of the inhaler into the spacer end.
Next, ask the patient to hold the lower portion of the inhaler between the thumb and middle finger, with their index or middle finger at the top of the canister, and have them support the spacer between the index finger and thumb of their non-dominant hand. Then instruct the patient to place the mouthpiece of the spacer between the upper and lower lips, to close the lips tightly around the mouthpiece, and to breathe normally.
Now ask the patient to depress the canister with their finger to release the medication and to take in a slow, deep breath. At the top of the patient’s inhalation, ask them to hold their breath for 10 seconds, or as long as it is comfortable, then release the finger from the top of the canister, and to remove the spacer from their mouth before they exhale slowly. If a second inhaled dose is ordered, have the patient wait for approximately 1 minute prior to administering the second dose.
If the medication is a corticosteroid, or if the patient requests, give the patient a cup of water to swish around in their mouth and spit out in the basin.
Now, document the date, time, and location of the medication administration in the electronic MAR. Remind the patient about the possibility of side effects from the medication and/or when they should call the nurse. Then leave the room and wash hands for at least 20 seconds with vigorous friction.

You’ve just watched JoVE’s video on administration of inhaled medications. You should now understand common indications for use, how they work, and how to administer inhaled medications. As always, thanks for watching!
