Question: A CHF patient who has a BP of over 140mmHg systolic who is getting 0.8mg of NTG for SOB, patient's BP drops below 140mmHg so NTG dosage is changed to 0.4mg, patient's systolic BP rebounds above 140mmHg. Does patient go back to getting 0.8mg of NTG or is it like the "once you are out, you are out" mentality that they stay at 0.4mg NTG?

General answers to this question from other paramedics I have asked usually say that the patient will continue to get 0.4mg of NTG regardless of systoloic BP, if it has dropped below 140mmHg at any time during the call. Thank you in advance for your time and help.


Thanks for the question. If once the patient's blood pressure fell with the 0.8mg of NTG dosing, it would be advisable to remain with the lower dosing of 0.4mg in subsequent dosing to avoid a repeat of the same outcome. Thanks for using this site!
