. Asthmatic pregnant woman. Woman using a pressurized aerosol Ventolin inhaler to control an attack of asthma. The Ventolin inhaler uses a drug called salbutamol which dilates the bronchial muscles, allowing air to pass to the lungs. The use of salbutamol for normal asthma control does not harm a pregnant woman or her baby. Nearer to birth, large doses of salbutamol as would be used in an asthma emergency can slow or prevent birth. Salbutamol has been used specifically to delay birth in some cases. This woman is eight months (32 weeks) pregnant. MODEL RELEASED
