Abstract:
Most national guidelines recommend moderate exercise during pregnancy, but this is not followed by the majority of pregnant women. Fear of exercise risks is among reported barriers. In contrast to most reviews focusing on late pregnancy risks, this review evaluates the association between exercise in the first trimester and the risk of miscarriage. A systematic review based on the EMBASE and PUBMED databases was conducted and 5 studies assessing the association between early pregnancy exercise and miscarriage were identified. Diverging findings were reported making no clear conclusion possible. New studies with participants included in the prepregnancy period are needed.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
