Hi, I have a question regarding PEP (positive expiratory pressure) devices. You know... these small devices in which the patients has to blow to increase the pressure in the lung to prevent atelectasis and to mobilize secretions... How many times does the patient have to do this? Five times an hour I have always learned. What do you people think?
