For the partner: the warning signs to learn

A federal campaign wrote this guidance for you. Most partners have never seen it.

CDC runs a campaign called Hear Her, aimed explicitly at People who support pregnant and postpartum women (including partners, family, and friends). It exists because, in CDC's words, more than 80% of pregnancy-related deaths could be prevented.

What CDC tells the partner to do, quoted in full
  • "Learn the urgent maternal warning signs."
  • "Listen to her concerns and encourage her to seek medical help."
  • "If something doesn't feel right, she should reach out to her provider."
  • "If she is experiencing an urgent maternal warning sign, she should get medical care right away."
  • "Be sure that she says she is pregnant or was pregnant within the last year."
  • "Offer to go with her to visit a health care provider and help her ask questions."
  • "Support her through follow-up care."
Two of those seven are pure informed consent, written by CDC. The fifth exists because clinicians outside obstetrics routinely fail to connect a symptom to a pregnancy that ended months ago.

The signs themselves. This list was developed by the Alliance for Innovation on Maternal Health and is published by CDC. It applies during pregnancy and for the whole year after birth.

SignWhat it looks like
Headache that will not go away or gets worseWorst headache of her life, thunderclap onset, or with blurred vision or dizziness
Dizziness or faintingFainting, ongoing dizziness, or a gap in time she cannot account for
Changes in visionFlashes, bright spots, blind spots, blurred or double vision
Fever 100.4°F (38°C) or higher
Extreme swelling of hands or faceCannot bend fingers or wear rings, face puffy, lips or mouth swollen or numb
Thoughts of harming herself or the babyHopelessness, feeling no control, unwanted frightening thoughts
Trouble breathingIncluding trouble breathing lying flat, or needing pillows to sleep
Chest pain or a fast-beating heartTightness, pain to back neck or arm, pounding or skipped beats
Severe nausea and vomitingUnable to drink for 8 hours or eat for 24
Severe belly pain that does not go awaySharp, stabbing, sudden or worsening
Baby's movement stopping or slowing (during pregnancy)There is no specific number of movements that is considered normal. A change in your baby's movement is what is important.
Bleeding or fluid leaking (during pregnancy)More than spotting, fluid leaking, or foul-smelling discharge
Bleeding or discharge after the birthSoaking through one or more pads in an hour, or clots bigger than an egg
Severe swelling, redness or pain in a leg or armUsually one calf; red, swollen, warm. Any time in pregnancy and up to 6 weeks after birth
Overwhelming tirednessSudden, not chronic. So tired that you don't get up to take care of your baby

CDC's own closing caveat, which belongs with the list: This list is not meant to cover every symptom you might have. If you feel like something just isn't right, or you aren't sure if it's serious, talk to your health care provider. Be sure to tell them if you are pregnant or were pregnant within the last year.

Why you should learn these rather than assume she was toldA study of 52 nurses across six hospitals found that warning signs were not the primary focus of the education, were most often discussed on the day of discharge, and that nurses did not consistently describe the same signs and symptoms... with each and every woman.

Discharge day is the worst possible moment to be given safety-critical information, and it is when most of it is given. Learn the list yourself, in advance.

Note also that CDC's Hear Her campaign is supported through a partnership with the CDC Foundation and funding from Merck. This guide holds others to a disclosure standard and applies it here.
