Priming a Beta-2 Agonist Aerosol Inhaler

Patient was educated on how to prime a Beta-2 agonist aerosol inhaler as follows: When a new canister of Beta-2 agonist aerosol inhaler is being used, the canister may not deliver the correct amount of medication with the initial actuation of the inhaler. So, priming of the canister should be done, to make the Beta-2 agonist inhaler ready for use. Insert the Beta-2 agonist canister firmly into the mouthpiece. Take the cap off the mouthpiece [...]

Long-acting and Short-acting Beta-2 Agonists

Patient was educated on long-acting and short-acting Beta-2 agonists as follows: Based on the duration of action, Beta-2 agonists are classified into long-acting and short-acting groups. Short-acting Beta-2 agonists start acting in about 1 to 5 minutes and can be effective for a duration of 3 to 4 hours. Short-acting Beta-2 agonists are used for treating mild intermittent symptoms of asthma and COPD, who are stable without any gross exacerbation. Since they act quick, they [...]

Nurse Teaching on Beta-2 Agonists and Mechanism of Action

Patient was educated on Beta-2 agonists and their mechanism of action as follows: Beta-2 receptors are located mainly at two sites-Bronchial smooth muscle in the respiratory tract and Smooth muscle of the blood vessels. Beta-2 agonists are medications that activate these Beta-2 receptors. They are mainly used with regards to their action on Beta-2 receptors of bronchial smooth muscle. Phosphorylation (Addition of phosphate) of myosin (contractile protein in the smooth muscle) is needed for the [...]

Nurse Teaching on Beta Receptors for Management of Hypertension

Patient was educated on Beta receptors used to management of hypertension as follows: Beta receptors basically are of 2 types: Beta-1 receptors found in the natural pacemakers of the heart, SA node and AV node and cardiac muscle. Beta-2 receptors found in the vascular smooth muscle and smooth muscle of the bronchi and bronchioles. Beta receptors respond to catecholamines (adrenaline and noradrenaline) in the human body, to bring on some important physiological actions. Stimulation of [...]

Precautions to be Exercised While Using Beta Blockers for Management of Arrhythmia-2

Patient was educated on precautions to be exercised while using Beta blockers for management of arrhythmia as follows: Beta blockers are contraindicated in individuals with abnormally slow heart rates, such as, in individuals with damaged natural pacemaker of the heart. Beta blockers are contraindicated in individuals with history of asthma, COPD, and with any other issues resulting in episodes of difficulty breathing.  Selective B-1 blockers that act only on the heart and have no action [...]
