What is the equation to measure Cardiac Output? - ANSWER-CO=HR*SV (heart rate)*(stroke volume) Stroke volume - ANSWER-The amount of blood moved in one beat. In one min, the entire blood volume of 5-6 L is circulated through the vessels What is the equation to measure minute volume? - ANSWER-MV=RR*TV (respiratory rate) (Tidal volume) Calculation helps to determine if a patient is breathing adequately Tidal volume - ANSWER-Amount of air that is moved into or out of the lungs during a single breath, generally 500 L in an adult Inspiratory reserve volume - ANSWER-The deepest breath you can take after a normal breath Expiratory reserve volume - ANSWER-Maximum amount of air that you can forcibly breathe out after a normal breath Residual volume - ANSWER-The air that remains in the lungs after maximum expiration Dead space - ANSWER-The portion of the respiratory system that has no alveoli, therefore, little or no exchange of gas between air and blood occur in these spots. (ex. mouth) Normal adult heart rate - ANSWER-60-100 bpm; during vigorous physical activity, the heart rate may rise to 180 bpm. At each beat, 70-80 mL of blood is injected into the heart Depolarization - ANSWER-The electrical charges of the network of tissues on the surface of the heart changes from positive to negative Repolarization - ANSW
