Med Surg Chapter 35 Notes: My notes: A deceleration is a decrease in the fetal heart rate below the fetal baseline heart rate. An early deceleration is defined as a waveform with a gradual decrease and return to baseline with time from onset of the deceleration to the lowest point of the deceleration (nadir) >30 seconds. Covid 19: Pregnant people seem to have the same risk as adults who are not pregnant to get Covid 19. Pregnant people have changes in their bodies that may increase their risk of some infections. Pregnant people have had a higher risk of severe illness when infected with viruses from the same family as COVID-19 and other viral respiratory infections, such as influenza. Mother-to-child transmission of coronavirus during pregnancy is unlikely, but after birth a newborn is susceptible to person-to-person spread. Breast milk provides protection against many illnesses and is the best source of nutrition for most infants. Pregnancy is a state of hypercoagulability. This is essential in protecting the mother against excessive blood loss during childbirth and placental separation. However, this state can increase the risk of thromboembolic disorders during the postpartum period. Three factors predispose pregnant women to thromboembolic disorders: stasis (compression of the large veins by the gravid uterus), altered coagulation (state of pregnancy), and localized vascular damage (may oc Risk factors for thromboembolic disorders are anemia, diabetes mellitus, cigarette smoking, obesity, preeclampsia secondary to exaggeration of hypercoagulable state, hypertension, varicose veins, pregnancy, oral contraceptive use, cesarean birth, previous thromboembolic disease, multiparty, inactivity, and advanced maternal age.cur during birthing process).
