A patient monitoring system including a sensing-recording device that attaches to a patient and a probe utilized by attending personnel at a trauma site. After an initial interaction between the probe and the sensing-recording device, the sensing-recording device samples one or more physiological parameters and stores time stamped readings in a first memory. The probe is adapted to take other measurements, download the data from the first memory of the sensing-recording device, manipulate the collective data and return data to a second memory in the sensing-recording device. The sensing-recording device continues to accumulate data in the first memory during transport of the patient from a trauma site to a medical facility.
