A pressure sensor is combined with a temperature sensor to monitor a patient's breathing patterns. The combination of sensors enables an analysis of the patient's breathing patterns to be made without the use of a face mask even if the patient breathes through the mouth or draws only very weak breaths. The patient's sleep is therefore less likely to be disrupted by the presence of the monitoring equipment and a more accurate diagnosis of any sleep disorder can be made.
