What is the SBP threshold commonly used to administer nitroglycerin in EMS?

Explanation:
Giving nitroglycerin relies on balancing pain relief with maintaining perfusion. Nitroglycerin dilates veins and arteries, which lowers blood pressure. If the systolic blood pressure is not high enough to tolerate that drop, perfusion to vital organs can worsen. In EMS practice, the safe cutoff is a systolic BP around 100 mmHg or higher. If the patient’s SBP is at or above this level, nitroglycerin can be considered; if it’s below, it’s withheld to avoid dangerous hypotension. The other thresholds would either risk excessive BP drop or unnecessarily restrict therapy, which is why the 100 mmHg mark is the commonly used threshold.
