The Medical Anti Shock Trousers (MAST®) apply a basic principle in a new way, helping you deal with emergency situations requiring rapid resuscitation, stabilisation and immobilisation.
The basic principle is the application of counter pressure (up to 104 Torr) on the lower half of the body. This increases both interstitial and tissue pressure and decreases vessel size, which leads to a reduction in transmural pressure of the lower area.
Each MAST® pant is a self-contained unit. Each part works effectively to slow or stop vascular bleeding, reduce spaces where haematomas can occur and support the central circulation of blood by increasing peripheral resistance to blood pressure. This means that more blood volume is immediately available centrally to support the vital organs.
Simple and safe - MAST ® is simple and safe to use. A well-trained team is able to apply this garment in 60 seconds or less. MAST® has been tested in preparation in hospitals and hospital environments for more than 20 years. The automatic release of the valves minimises complications and it becomes unnecessary to monitor the pressure, especially under extreme temperature and altitude.
MAST ® is useful to fix and stabilise the lower part of the body including muscular and skeletal injuries. MAST® minimises movement of the structure under the tissue, reduces bleeding and swelling, stabilises the patient during movement with minimal discomfort.
MAST® is able to temporarily stabilise the cardiovascular system for controlled fluid therapy and evaluation.
Secondary evaluations and diagnostic procedures can be achieved while MAST® is inflated.
While MAST® works on the lower half of the body, venipunctures in the upper half of the body become more accessible and allow for drug administration, transfusions and haematological evaluation.
Unlike non-invasive fluid exchange, MAST® can be safely applied and patients can be monitored for fluid therapy when needed.
MAST ® III - AT is modular and transparent, which allows emergency personnel to observe, assess and monitor the injuries, skin condition, and easy accessibility for insertion of femoral lines.
Stabilisation and transport:
Prevention of further blood loss, directing blood circulation to key areas and increasing blood pressure by maintaining artificial peripheral resistance allows traumatic and atraumatic patients to be stabilised quickly. This results in further advantages for an orderly transport of the patient and a more precise categorisation of the patient into critical or less critical injuries.
