Assessment Task 2 B Bertha, the story continues: Bertha is a 75 years old First Nations elder who is recovering from a fractured pelvis. She has been working with the physiotherapists to ensure that she does not lose strength before being discharged from hospital. Today she had a session with the physiotherapists. Before taking Bertha to the gym, a set of vital signs were collected before she gets out of bed. Results are: RR 14 bpm, SpO2 98%, BP 130/70 mmHg (Mean arterial pressure 90 mmHg), HR 74 bpm. The nurse tells the physios that Bertha is well and has no cardiovascular or respiratory diseases. The physiotherapists took her to the gym, where she undertook some exercises under their direction.  Collect cues: After the first round of exercises, they check her vital signs again. Her respiratory rate is now 20 bpm, her SpO2 is 100% on room air, BP is 140/80 mmHg (Mean arterial pressure 100 mmHg), and HR is 90 bpm. She is observed to be breathing deeply and using accessory muscles.  1.…

Task 1. A man takes the medicine - the block of slow calcium channels nifedipine. How and why will change: a) the frequency of heart contraction; b) the force of heart contraction?

Task 1. A woman of 35 consulted a doctor with the complaints on weakness, decrease capacity for work. In blood analyses it was found: hemoglobine - 110 g/l, erythrocytes – 2,7 · 10¹2/l, color index - 1,2; leucocytes - 4,5 - 109/1, leucocyte formula without changes, thrombocytes - 120 - 10%/1, blood coagulation time - 5 minutes, bleeding time (duration of bleeding) - 6 minutes, blood plasma proteins - 65 g/l, erythrocytes sedimentation rate -19 mm/hour.

Left ventricle:

Task 3. During some diseases, one can observe the diminishing of the duration of the action potential of typical cardiomyocytes. This makes conditions for pathological recirculation of excitatory impulses (action potentials) by the heart structures and it violates the pump`s function of the heart. Explain the reason for it.

Q4.4. Describe using diagrams as appropriate the cardiac conduction system within the heart. Sketch and outline the major features of an ECG in a healthy individual.

Work 3. Express assessment of the functional system indicators, which provides the optimal level of blood pressure (for metabolism). Human functional states (quiet wakefulness, physical and psycho-emotional tension, stress, fatigue) are accompanied by a change in the tonus of the autonomic nervous system, which leads to a change in the heart rate and blood pressure. Therefore, the heart rate, blood pressure and indexes calculated on their basis can be used as indicators of a person's functional state. Equipment: clock with a second hand, a sphygmomanometer, a stethoscope, a calculator. The content of the work. Measure your blood pressure and heart rate, and assess your functional state on this basis. Formulas for calculation and evaluation criteria are given below. Measure the heart rate. Result: heart rate = If the heart rate is less than 50 beats/min, the patient has a bradycardia. If heart rate is between 50 and 90 beats/min. - normocardia If the heart rat is more than 90 beats/…
