Orthostatic Hypotension Orthostatic hypotension is one of several signs and symptoms of hypovolemia. Hypotension is the medical term for low blood pressure .[brighthub.com]
One of the signs and symptoms of hypovolemia is tachycardia (Nursing, 2000). Tachycardia is the medical term for rapid heartbeat (Mayo Clinic).[brighthub.com]
Class I hemorrhage (loss of 0-15%) In the absence of complications, only minimal tachycardia is seen. Usually, no changes in BP, pulse pressure, or respiratory rate occur.[emedicine.medscape.com]
Tachycardia is sensitive but not specific indicator. Prolonged capillary refill ( 2 seconds), especially when combined with tachycardia, is more specific, although it may be difficult to measure. Cold skin and decreased urine output may be present.[openanesthesia.org]

The heart muscle is affected by the reduced amount of blood plasma, resulting in tachycardia ( 100bpm) and increased respiratory rate (over 20 breaths/minute).[byebyedoctor.com]
A narrowpulsepressure in a hypovolemic shock patient indicates a decreasing cardiac output and an increasing peripheral vascular resistance.[ems1.com]
Class IV hemorrhage (loss of 40%) Symptoms include the following: marked tachycardia, decreased systolic BP, narrowedpulsepressure (or immeasurable diastolic pressure), markedly decreased (or no) urinary output, depressed mental status (or loss of consciousness[emedicine.medscape.com]
These circulation changes include tachycardia, narrowingpulsepressure, possible systolic hypotension, capillary refill time 2 seconds, cool/pale skin, weak to absent peripheral pulses, reduced urine output.[acls-algorithms.com]

Mild postural dizziness had no value in the diagnosis of hypovolemia. Normal capillary refill time ranges from two seconds in children and adult men to three seconds in adult women and four seconds in the elderly.[aafp.org]

CONCLUSIONS: CT evidence of FI is a good indicator of hypovolemia and an accurate predictor for prognosis in trauma patients with blunt solid organ injuries.[ncbi.nlm.nih.gov]
Postoperative organ dysfunction severely affects the prognosis of surgical patients. Despite several trials evaluating restrictive or liberal fluid strategies, the ideal fluid replacement strategy remains controversial.[clinicaltrials.gov]
Elderly have a poor prognosis compared to young adults.[howshealth.com]
In addition, some forms of shock have a better prognosis than others. Hypovolemic shock, if you can replace the fluids and find the leak and plug it, has much better odds than shock resulting from a bacterial infection or heart failure.[thenakedscientists.com]
We should always take the etiology of CSF hypovolemia into consideration, and especially pay attention in patients with pneumocephalus and subdural fluid collection alongside brain sag on computed tomography.[ncbi.nlm.nih.gov]
