Can you be hypovolemic and not be hypotensive? The body is always adapting vessels to match the volume, so couldn't you be normal tensive and still be dehydrated? I had a pt today with dizziness and weakness Bp 146/78 hr 130. 300 cc bolus decreased his hr to 100.
You administered a bolus and then the HR increased. Bolus of what?
A doctor at the receiving ER will hear or read this and turn to someone and say "Is it a coincidence or is the bolus creating the change?". Or something less charitable about the field person presuming that their treatment caused a change when there is only timing to suggest it did (unless the bolus had drugs in it).
Try something like this: "1500hrs: Pt reports dizziness and weakness, Bp 146/78 hr 130. Start IV 300ml XCYZ solution" (site)
1510hrs: IV 300 ml of XYZ solution IV completed ..." and give new vital signs, other S/S.
HR of 130...regular, irregular? (Irregularly-irregular, or regularly- irregular?). EKG reveal sinus tach, or what? (Don't trust pulse-ox, its software can be confused by irregular rhythms into inaccurate rate displays). A paroxysmal arrhythmia and palpated pulses (or pulse ox) could yield the same result if you did nothing but play them music from their IPod.
Yes, you can be normotensive/normal pulse rate and still have the potential to slip back into a hypovolemic state due to a number of situations tipping the circulating fluid volume versus/and circulatory vascular volume readings the wrong way. (Not a balance scale, more of a johari window diagram).
Some causes:meds, continued bleeding, release of tourniquet or entrapment effects, sudden electrolyte imbalance (crush syndrome or IV potassium overdose ala Kavorkian). Decompensation.
