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.
During contraction of a muscle, calcium ions bind to... the actin myofilament. the troponin molecule. the tropomyosin molecule. the sarcoplasmic reticulum. the sarcolemma. 2. The bond between the actin and myosin head is broken when... an ATP molecule binds to the myosin head.an ATP molecule binds to the actin molecule. an ATP molecule breaks down on the myosin head.he bond between the actin and myosin head is broken when... an ATP molecule binds to the myosin head. an ATP molecule binds to the actin molecule. an ATP molecule breaks down on the myosin head.
