Colton Meads Respiratory Physiology lab. A person’s respiratory rate can change for several reasons; conditioning, activity level, health conditions, sympathetic nervous response or medications. The average respiratory rate is about 15 breaths/min (+/- 3). However, athletes may have a rate around 8-10 breaths/min. and patients with health conditions may be closer to 20 breaths/min or higher. Your body does its best to adapt to the stresses placed upon it. Similar to the heart, the more work it does, the more efficient it becomes and the fewer beats or breaths you may need to take for the same results. Let’s review how you can evaluate a patient’s respiratory function. The total amount of air moved in and out of the lungs each minute depends on the size of the breath (tidal volume) and how many breaths occur in that minute (respiratory rate). Pulmonary Ventilation = Tidal volume x respiratory rate Some of the air in the lungs does not move and only takes up space in the pathway. This is the dead space. Only the air in the alveoli exchanges gases with the blood in the capillaries.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
