Prolonged labor is the inability of a woman to proceed with childbirth upon going into labor. [1] Prolonged labor typically lasts over 20 hours for first time mothers, and over 14 hours for women that have already had children. [1] Failure to progress can take place during two different phases; the latent phase and active phase of labor. [1]
In some instances, an impending respiratory arrest could be predetermined by signs the patient is showing, such as the increased work of breathing. Respiratory arrest will ensue once the patient depletes their oxygen reserves and loses the effort to breathe. Respiratory arrest should be distinguished from respiratory failure.
Labored breathing is distinguished from shortness of breath or dyspnea, which is the sensation of respiratory distress rather than a physical presentation.. Still, many [2] simply define dyspnea as difficulty in breathing without further specification, which may confuse it with e.g. labored breathing or tachypnea (rapid breathing). [3]
In Africa and Asia obstructed labor affects between two and five percent of deliveries. [8] In 2015 about 6.5 million cases of obstructed labour or uterine rupture occurred. [ 5 ] This resulted in 23,000 maternal deaths down from 29,000 deaths in 1990 (about 8% of all deaths related to pregnancy ).
This causes a significant increase in output of the left ventricle and increase in stroke volume. Subsequently, calcium channel activity increases and potassium channel decreases furthering ductal constriction. Functional closure of the ductus arteriosus occurs within the first 24 hours, with permanent closure following within 4 weeks.
The increase in kidney clearance during pregnancy causes more iodide to be excreted and causes relative iodine deficiency and as a result an increase in thyroid size. Estrogen-stimulated increase in thyroid-binding globulin (TBG) leads to an increase in total thyroxine (T4), but free thyroxine (T4) and triiodothyronine (T3) remain normal. [5]

Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics. [2] [1] [3] The term "non-reassuring fetal status" has largely replaced it. [4]
