    00:00 Okay, so Short-acting versus Long-acting.

    00:04 Remember these short-acting ones, they'll feel it almost immediately.

    00:08 In about 30 to 60 minutes they'll hit the largest part of that effect, the peak of that effect and it should last about 3 to 5 hours.

    00:15 So short-acting, they'll feel it almost immediately but remember, it's never quick enough when you can't breathe.

    00:21 It'll hit its maximum peak in about 30 minutes to an hour and then it should last 3 to 5 hours.

    00:27 So short-acting kick in quicker but they don't last as long period of time.

    00:33 Remember you wanna take for greater than 1 puff, you wanna wait at least 1 minute in between puffs.

    00:39 If it is a medication, if you're giving a bronchodilator and then a corticosteroid, remember to wait at least 5 minutes.

    00:47 Now if the patient isn't responding well with the inhaler, consider you might need to take a breathing treatment or a nebulizer.

    00:54 And we cover those in our other video on looking at unique ways we deliver repiratory meds.

    00:59 So you might wanna check that out for more information.

    01:02 Now treatment goal of a short-acting beta-2 adrenergic agonist or a SABA is to make sure that we can open that airway quickly.

    01:11 These are for attacks, exacerbations the patient's experiencing.

    01:15 But keep in mind, we're stimulating that sympathetic nervous system.

    01:20 So some of the side effects your patient might feel is a tachycardia, sometimes people describe it like, " I feel like my heart is gonna beat out of my chest." So, I've seen a lot of patients but unfortunately really weigh out if they wanna deal with that tachycardia and that (sound) feeling versus breathing.

    01:36 So know that it's not an easy answer sometimes but be aware that when someone uses a SABA, they're gonna have that kind of shaky, tachycardia - that's a really fast heart rate kind of feeling.

    01:49 Now we'll take a look at the long acting beta-2 adrenergic agonist or the LABAs.

    01:54 Now the onset varies with the drugs, so depending on which drug you take, there will be a different period of time at when it actually kicks in.

    02:01 We're using this for long term control, not for an emergency rescue.

    02:06 And you shouldn't use these medications as monotherapy.

    02:09 And when we say monotherapy, it means these shouldn't be used by themselves.

    02:13 If you're taking a LABA, you should have some type of SABA available to that patient.

    02:18 So these are not good for monotherapy.

    02:21 So make sure you make a note of that that these aren't used alone.

    02:25 They're always used in combination with another treatment option.

    02:28 Now glucocorticoids are probably part of this plan and they would be considered a long acting medication but they're not a beta-2 adrenergic agonist.

    02:38 So we put that note in there just to remind you that in addition to a LABA, we may consider a glucocorticoid.

    02:44 That's also a long acting medication just not a beta-2 adrenergic agonist.

    02:48 So combo inhalers are really easy.

    02:51 They're more expensive but they're great for the patient because we can do combination medications, the patient only has to administer it one time instead of having to carry, keep up, maintain 2 different types of medications.
