Background and Objectives: The performance of the emergency medical services are the immediate access to patients in the scenes. As a treatment in patients with low concentrations of oxygen in the blood to be treated with oxygen through the nose or the oxygen mask. In some patients, conditions such as congestive heart failure or a severe pneumonia will not respond to oxygen that way. Target device to open the airway pressure device is brought into use in solving such problems. The device has been recommended for use in emergency medical services in the United States, that no doctors in ambulance.

Methods: In emergency medical services, the patients’ history were  reassessed, according to the medical professional standards. Those patients with low blood oxygen can get the oxygen device used in the study. Changes are taking note of the oxygen in the blood, respiratory rate after wearing the device blowing pressure to open the airway. The doctor who ordered the use of such devices are nurses trained to use the device as an input to the patient.

Results: The pilot study consisted of 48 patientswhen entering the target device pressure to open the respiratory, the oxygen saturation increased from first minute with of 70.4% increase to 91.2% and 96.3% in the third and fifth minutes, respectively. The respiration rates after the device blew pressure to open the airway found that respiratory rate decreased from 36.2 times / min to 22.4 and 16.4 times / minute, in the third and fifth minutes, respectively. In conclusion equipment blowing pressure to open the airway is effective in increasing the oxygen saturation and decreasing respiratory rate
