Biology students of alpha team are investigating the effect of fresh pineapple juice on cherry gelatin. The lab directions are clear: water + gelatin as a control and water + pineapple juice + gelatin as the experimental setup. However, instead of using distilled water, a team member uses liquid from a dropper bottle of hydrochloric acid. Test tubes of experimental and control tubes are refrigerated overnight. All other teams find a soupy red liquid the next day in the experimental setup and semi-solid gelatin in the control while both Alpha team gelatin setups are semi-solid. Why are their results different?

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.
