Closing-Time Dyspnea: New-Onset Heart Failure or Something Worse?
A 62-year-old woman walks in 20 minutes before closing with three days of worsening breathlessness. She now naps in a chair, has 2-pillow orthopnea, and both ankles are tight. Vitals: HR 104, BP 148/88, RR 24, SpO2 92% on room air, T 37.1 C. Bibasilar crackles to mid-lung, JVD 10 cm, trace pedal edema. ECG shows sinus tachycardia with no ST changes and a normal axis. The clinic's point-of-care BNP reads 480 pg/mL (cutoff 100). In-office radiograph shows vascular congestion without infiltrate. She lives alone, has no primary care physician, and drove herself; her daughter is 40 minutes away. The clinic has no telemetry, no running IV fluids after 6 pm, and closes in 90 minutes. She asks, 'Can't I just take a water pill and follow up Monday?'
1. What is your disposition, and how do the BNP, the ECG, and her social situation each push you toward or away from it?
Read the worked answer
Disposition: emergency department transfer by EMS. The reasoning is about capability, not the number on the device.
- BNP 480 pg/mL is abnormal but not dramatically so. It supports heart-failure physiology (orthopnea, JVD, crackles, congestion on film) but is too nonspecific to be diagnostic and is shifted by obesity, age, and renal function. It cannot distinguish ischemic, valvular, or tachyarrhythmic causes, and that distinction is the whole question.
- The ECG is normal, but a normal tracing at hour three does not exclude ACS. That requires serial troponins and, in new heart failure, echocardiography. Urgent care has neither and no telemetry.
- SpO2 92% with HR 104 at rest means she is already mildly decompensated; a 40-minute drive or a night alone is a real risk.
- Social factors cut the other way: undiagnosed, no PCP, lives alone, no reliable follow-up. Outpatient diuresis assumes a known heart-failure patient with an established plan and a safety net.
Transport should be by EMS with monitoring rather than self-drive, because she is hypoxemic and could decompensate en route.
2. What do you do in the 30 minutes before transport, and should she receive a dose of furosemide?
Read the worked answer
- Oxygen titrated to SpO2 94-98%, with continuous pulse oximetry and vitals every 15 minutes.
- Position upright; she should not walk to the car or the ambulance.
- IV access with a saline lock only. Do not volume-load a congested patient.
- Aspirin 325 mg chewed if ACS remains on the differential and there is no bleeding or true allergy. Low risk, high upside in undifferentiated dyspnea.
- Print a copy of the ECG and send it with her; do not let the only trace stay in your chart.
- Warm handoff by phone to the receiving ED: vitals trend, medications, BNP value and device/lot, ECG interpretation, and the patient's own words.
Furosemide: not routinely, and never as a substitute for transfer. If transport will be delayed more than 45-60 minutes and she remains congested and hypertensive, a single oral dose (40 mg) with a documented rationale is defensible. If she is leaving in ten minutes, the ED can decide with better information and monitoring. Avoid it if she is borderline hypotensive or vomiting.
Document: vitals trend, SpO2 on room air, ECG interpretation, POC result, the shared decision-making conversation, and the mode of transport.
3. She refuses EMS and says she will drive herself home and call her daughter. How do you respond?
Read the worked answer
Treat this as a negotiation with a capable adult, not a confrontation.
- Assess capacity briefly and document it: she is alert, oriented, understands the options, and can state the risks back to you.
- Name the specific risks to her, not generic ones: respiratory failure overnight while alone, an arrhythmia, syncope at the wheel, and delay in treating a possible coronary occlusion. Tell her plainly that she should not be driving herself.
- Offer concrete alternatives: EMS now, or her daughter drives her directly to the ED this evening, or a rideshare with an escort. Refusing EMS is not refusing care, and she may accept going by car.
- Keep treating while you talk - oxygen and monitoring do not stop because she declined transport.
- If she still refuses everything: have her sign an against-medical-advice form, write the risks in her own words in the chart, give written return precautions, arrange a follow-up phone call that night, and have a second staff member witness the discussion.
Do not withhold information about the seriousness of the findings to persuade her, and do not threaten her; document two documented attempts at persuasion and the alternatives offered.
