treat the patient and their symptoms. use the diagnostics as a tool to assist you in your treatment. If you patient is showing such vital signs and acting normal, think about why it is like that. ask them if it is normal for them.
My friend is the same age as me, and roughly the same height and weight. My normal vitals signs are around a HR of 52, BP 102/78 RR 12. Where as his, are HR in the 80/90s, BP 140/90, RR 18. Both of them are normal for ourselves. If I call 911 for an issue, and you read those vitals for me, don't treat me for hypotension or bradycardia, because they are normal for me. Treat ME, the patient.
