i do not think that the auto vital machines are very accurate especially the b/ps. i have encountered several intances on the floor i work with inaccurate b/ps from the machine. if i am going to give a b/p med i always recheck them manually just to be safe and usually it is to my advantage because my reading is no where close to the auto b/p reading. i have noticed that a lot of times the auto machines tend to run higher for b/p for some reason. i think they are good at showing a trend as with vitals that have to be taken often such as surg. vitals or blood vitals but i would rather b/p be taken with a good old fashioned cuff.

I worked as a tech for about 6 months. Some evenings I would have 18 patients to do vitals on, feed, turn ect. I was a patient care technician so i could also do blood draws, catheters, dressing changes, blood sugars.... I trusted the machines b/c usually if it was high or low i would check it manually and get the same thing. The pulse was always accurate when compared to the hand held pulse Ox machine. I would count as well if it was high or low and they would be accurate.
If I had to do vitals manually I wouldn't have time to do anything else!! So I am very thankful they exist.. But if you ever doubt them.. definately check it manually!!

I don't trust them. We do use them and if the patient's vitals are pretty normal, I don't mind so much. But if their condition changes, I do check them manually or if there's a reading that's too high or too low, I check them again manually.
At the previous hospital where I worked, they ended up taking all the Dynamaps off the floors and said we were to take vital signs manually only.
The size of the cuff makes a difference also. If it doesn't fit correctly, you'll get incorrect vitals. I've also found that if a patient tenses up their muscles, you'll get a higher BP. Also, you can get a lower reading sometimes on the left arm than on the right.

The other night, my patient was an avid runner and the bp machine said that her heart rate was 200..when i rechecked myself, it was 48. Also (and this is funny) my friend at Children's hospital said that a CNA reported that all patients had high pressures one night. my friend put the bp cuff on a cabbage patch doll for laughs and the machine actually read a bp haha...so no, i usually do not rely on the machines!

I don't always trust the automatic machines. If there's something abnormal, then I ALWAYS check it for myself. If the patient is moving, the BP reads higher, than a manual BP. The sat will not be accurate if the patients fingers are cold, or they have nail polish on, and the HR will not be accurate if your patient has an irregular heart rate. As a general rule....I just do it "the real way". It's even quicker.

We use them but we have backups. The sat checks will not be accurate if the pt's fingers are cold, no matter how high the sat really is. I don't trust the BP/pulse readings if the pt cannot hold his/her arm relatively still.
