LC 3- Spring Flashcards
what are some relative contraindications for exercising while pregnant
-severe anemia
-unevaluated maternal cardiac dysrhythmia
-chronic bronchitis
-poorly controlled type 1 DM
-extreme morbid obesity
-extreme underweight
-history of extremely sedentary lifestyle
-intrauterine growth restriction in current pregnancy
-poorly controlled HTN
-orthopedic limitations
-poorly controlled seizure disorder or hypothryroidism
-heavy smoker
what are some absolute contraindications for exercising while pregnant
-hemodynamically significant heart disease
-restrictive lung disease
-incomplete cervix/cerclage
-multiple gestation at risk for premature labor
-persistent second or third trimester bleeding
-placenta previa after 26 wk gestation
-premature labor during current pregnancy
-ruptured membranes
-preeclampsia/pregnancy-induced hypertension
what are acute physiological responses that increase while a pregnant patient is exercising
VO2
CO
VT and VE
VE/VO2 and VE/VCO2
what does exercising during pregnancy prevent
-excessive gestational weight gain
-gestational diabetes
-postpartum weigh gain
-improvement of depressive symptoms
what does exercising during pregnancy decrease
-risk of preeclampsia
-incidence symptoms of low back pain
-risk of urinary incontinence
guidelines for exercise intensity for pregnant patients
150 min/wk of moderate exercise OR
75 min/wk of vigorous intensity aerobic exercise
moderate exercise intensity during pregnancy
3-5.9 METs, RPE 12-13/20
vigorous exercise intensity during pregnancy
> 6 METs, RPE 14-17/20
resistance exercise guidelines for pregnancy
8-10 or 12-15 reps performed to point of moderate fatigue
benefits of exercise for pregnant women
lower incidence of LBP
shorter labor duration
shorter recovery time/faster return to activity in postpartum
warning signs to stop exercise during pregnancy
-vaginal bleeding or amniotic fluid leakage
-SOA prior to exertion
-dizziness, feeling faint, or headache
-chest pain
-muscle weakness
-calf pain or swelling
-decreased fetal movement
-preterm labor
causes of dyspnea
-low fitness
-asthma, COPD, restrictive diseases
-MS abnormalities
-neuromuscular diseases
-left ventricular heart failure
-cardiac arrythmia
-ischemic heart disease
-valvular heart disease
-anemia
what is PEEP and why is it used
peak end respiratory pressure
used to maintain a positive pressure in the airways at the end of exhalation, preventing alveolar collapse and improving oxygenation by keeping the air sacs open
what decreases alveolar surface tension
sufactant
when does tidal volume plateau during exercise
60% of vital capacity
disruptions of airflow
-pulmonary ventilation is unequally distributed
-basal receives more ventilation than apex
-during exercise, airflow becomes more evenly distributed
bulk flow
movement of air molecules into/out of lungs
intrapulmonary pressure
pressure in alveoli
during inspiration, what has the most pressure
atmosphere has more pressure so air flows into the lungs increasing intrapulmonary pressure (becomes more negative)
max value for VE (1/min)

max bf value (br/min)
40
max VT value (1/breath)
