What about the effect of ventolin raising HR and BP? Surely this is undesirable in a patient suffering from cardiogenic pulmonary oedema.
Changes should be not at all to marginal. I couldn't even begin to count the number of times I've given albuterol (often with ipratropium) and I can't think of one time where the patients heart rate increased noticeably. Same for BP. Regardless, if you reassess and believe the patient to be in CHF (in a situation where you first treated with a bronchodilator due to vague presentation), then you will administer NTG (GTN). That will counter any conceivable change in BP. As for HR, the increase probably wouldn't be anymore than what you'd see with NTG.

I couldn't find a similar one for sick patients (not too much time on my hands - gotta get back to studying), but if you can find some, please link them.
