What indicators are included in the general monitoring of shock, and what is its significance?

General monitoring of shock includes: \x0d\a, the state of consciousness can reflect the blood circulation of brain tissue; \x0d\b, skin and limb manifestations can reflect microcirculation and peripheral circulation; \x0d\c, pulse and blood pressure: the increase of pulse rate occurs before the decrease of blood pressure, which is an early diagnostic index of shock. The decrease of blood pressure, systolic blood pressure less than 90mmHg and pulse pressure less than 20mmHg are the manifestations of shock; Increased blood pressure and pulse pressure are signs of improvement. \x0d\d, breathing: deep and rapid breathing indicates metabolic acidosis. Shortness of breath, oxygen saturation less than 90%, arterial oxygen partial pressure less than 60mmHg, no significant increase after inhaling pure oxygen, suggesting acute respiratory failure (ARDS). Tidal breathing usually suggests brain edema and intracranial hypertension. \x0d\e, urine volume is a valuable indicator of renal blood perfusion, which can also reflect the blood perfusion of living organs. Urine volume < 30ml, high specific gravity, suggesting insufficient blood volume. Such as urine volume
