DNI Status, Noninvasive Ventilation, and a Family That Says "No Machines"
Mrs. B, 78, has advanced COPD with three admissions in six months. She has a signed DNR/DNI order and her daughter is her healthcare proxy. At 1900 she is in respiratory distress: RR 34, accessory muscle use, SpO2 82% on a nonrebreather, ABG pH 7.20, PaCO2 80 mm Hg. She is alert enough to say, "I can't breathe - help me." The oncoming nurse says, "She's a DNI, so there's nothing to do except morphine." The resident asks whether BiPAP is "even allowed." The daughter is at the bedside and says, "Do everything, but no machines."
1. Is BiPAP consistent with a DNI order? Explain your reasoning and what you would clarify before acting.

DNI refers specifically to endotracheal intubation - it does not prohibit noninvasive ventilation. BiPAP can be an appropriate, even comfort-oriented, intervention and may be a bridge that avoids intubation. Withholding all treatment because of a DNI label is a common and harmful misinterpretation.
What to clarify:
- What does "no machines" mean to the daughter? The ventilator? ICU transfer? Any mask device? Ask what the patient herself has said about times like this: "What did she tell you she wanted?"
- Read the advance directive for what is actually specified (intubation, ICU, CPR, antibiotics, fluids).
- Assess the patient's own capacity and wishes - she is alert enough to say "help me," which is a request for relief, not for abandonment.
- Frame the plan around goals: relief of dyspnea and suffering, with a defined ceiling of care. If the daughter's interpretation conflicts with the patient's wishes, request an ethics consult and a palliative care/goals-of-care meeting rather than deciding unilaterally.
Meanwhile, treat the distress: titrate opioids for air hunger, position, coach breathing, and do not leave her alone.
2. She improves on BiPAP but now says she feels "trapped" and wants the mask off. Her daughter insists it stay on. What do you do?

A patient with decision-making capacity can refuse or stop treatment, even when family disagrees.
Steps:
- Assess capacity at the bedside: does she understand the information, appreciate the consequences of stopping, reason with it, and communicate a consistent choice? Document the assessment.
- Honor her choice. Remove the mask when she asks, explain what will happen, and immediately offer alternatives for comfort - opioids for dyspnea, anxiolytics if needed, positioning, a fan, mouth care, presence.
- Talk with the daughter gently and without framing it as giving up: "Your mother is telling us what she wants. Here is how we will keep her comfortable."
- Notify the provider and update orders to a comfort-focused plan; involve palliative care and ethics if the daughter continues to insist.
- Document her exact words, the capacity assessment, who was present, options offered, and the decision.
The nurse's obligation is to advocate for the patient's own stated wishes, not to defer to the loudest voice in the room.
3. How would you document and communicate the plan so the next shift does not relitigate it at 0300?
Read the worked answer
- Quote the patient verbatim and record the capacity assessment, who was present, the options offered, and the decision.
- Make orders concrete, not symbolic: "NIV trial with goal SpO2 __; no intubation; no CPR; opioids for dyspnea; no ICU transfer; palliative care consult." Ambiguity is what causes a crisis at 0300.
- Use structured handoff (SBAR) and read the goals-of-care note at every shift change; flag the chart and the bedside whiteboard so the plan is visible to everyone entering the room.
- Update the proxy and family after each change; note who holds decision-making authority and whether the patient retains capacity.
- Escalate through the chain of command and ethics if any clinician later acts against the documented plan - and document that escalation.
Ethical practice here is not just knowing the definitions of DNR/DNI; it is making the patient's values operational and durable across a team, a shift change, and a family in crisis.
