Clinical observations include estimation of haemoglobin-oxygen saturation (SpO 2, pulse oximetry), oxygen delivery, respiratory rate, respiratory distress, heart/pulse rate, blood pressure (systolic, diastolic and mean), temperature, level of consciousness OR level of sedation, and a pain score.linical observations include estimation of haemoglobin-oxygen saturation (SpO 2, pulse oximetry), oxygen delivery, respiratory rate, respiratory distress, heart/pulse rate, blood pressure (systolic, diastolic and mean), temperature, level of consciousness OR level of sedation, and a pain score.
Quick Answer. Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages.
How do calcium ions initiate contraction in skeletal muscle fibers? A. Calcium ions provide the energy necessary for the myosin head power stroke. B. Calcium ions bind to tropomyosin, exposing the active sites on actin. C. Calcium ions bind to troponin, changing troponinâs shape.
