Which of the following will improve a running workout when a person wants to monitor heart rate?

For this question, I think your best answer would be changing to a treadmill that has handle sensors. Now, I'm not sure if that's correct because I don't see you listed any answer choices. But I'm positive that is correct. If you need more help please feel free to leave a comment down below!

20 times a minute is usually the average respritory rate of an adult. additionally the patient is breathing on his own, is clearly maintaining his airway, and is intaking a sufficient amount of air. you shouldn't use a bag valve mask, cpap, or other form of positive pressure ventilation, unless the patient has lost control of his airway, and is not breathing (apneic) or has rapid breathing or slow and shallow respirations. this patient would most likely and should be put on an non-rebreather mask or nrb attached to 100% high flow oxygen at 15 l/min. don't use a nasal cannula, as the amount of oxygen it provides is limited with a rate of 6 l/min.
