The unique Ambu double wall concept clearly distinguishes the genuine Ambu bag from all other manual resuscitators. It provides the “touch” Ambu bags are famous for. The thin outer cover gives the user a very good “fingertip” feeling for how much pressure is needed, while the inner lining with its air holes allows rapid recoil for optimum stroke volume. This gives you complete control of the amount of pressure delivered to the patient and enables artificial respiration with quick frequencies, if needed.

Another unique effect of the Ambu double wall is that the elasticity of the outer cover limits airway pressure from exceeding approximately 7 kPa (70cm H20) during operation of the Ambu Mark IV Adult with one hand. The Ambu Mark IV Baby is fitted with a pressure-limiting valve that opens when pressure in the valve reaches approximately 4.0 kPa (40 cm H2O). If more pressure is required, it can be easily overridden by pressing the attached override cap.

The slim design and crystal clear casing housing the unique single-shutter valve allow unimpeded observation of the valve operation and make it easier to view and manage airflow to the patient. 

Both sizes feature a swivel between the patient valve and the mask, as well as between the valve and bag, making it possible to change positions or switch hands without interrupting patient ventilation.

Both Mark IV Adult and Baby are made of silicone rubber and are 100% latex-free.
