Aneurologist is testing the effect of a drug on response time by injecting 100 rats with a unit does of the drug, subjecting each to neurological stimulus and recording its response time. the neurologist knows that the mean response time for rats not injected with the drug is 1.2 seconds. the mean of the 100 injected rats response times is 1.05 seconds with a sample standard deviation of 0.5 seconds. do you think that the drug has an effect on response time?

What's the question again?

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.
