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.
In turn this triggers the sarcoplasmic reticulum to release calcium ions into the muscle interior where they bind to troponin, thus causing tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce contraction.
Calcium and magnesium work together to control muscle contraction. Both minerals interact with the proteins actin and myosin -- structural proteins that shorten with each muscle contraction, then lengthen to relax your muscles.ctin and myosin rely on calcium to shorten and contract your muscles, then rely on magnesium to relax after a contraction. While low calcium levels primarily affect your bones -- causing bone loss and putting you at risk for osteoporosis -- magnesium deficiency affects your muscles, causing abnormal muscle contraction.
