How often should you use deep relaxation breaths

For me, I have to do it quite often. But a for anyone else. It may be due to stress or anger and they may do it 4 or 5 times a week or, the'll do it to calm themselves. It may take a few breaths it may only take one. It all depends on the person. 

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.
