Sound waves through the chest and to determine a sound velocity value with which the transmitted sound waves propagated through the chest and to compare the determined sound velocity value with a plurality of predefined sound velocity data each associated with a predefined condition of the chest including pneumothorax, hemothorax and/or normal state thereby determining one of a pneumothorax condition, a hemothorax condition and/or a normal condition of the chest of the patient. Sound waves propagate through the chest and are received by the sound receiver 30. The sound receiver 30 receives and transmits sound signals processing unit 40, which processes the sound signals to detect a condition of the chest from a plurality of predefined conditions including pneumothorax, hemothorax and/or normal state of the chest and outputs a corresponding notification from a plurality of predefined notifications each corresponding to a predefined condition of the chest via the display unit 50. Optionally, the measuring means 80 may provide a value of chest diameter and/or body mass index of the patient automatically to the processing unit 40 for using during determining the condition of the chest, e.g. when the extandable element 72 is extended by the user during arrangement of the sound emitter 20 and the sound receiver 30 at different locations of the chest, for example one of them at a front side of the chest and the other one at a rear side of the chest. Optionally, a value of chest diameter and/or body mass index and/or age of the patient may be manually submitted to the processing unit 40 via keypad 60 for using during determining the condition of the chest. According to this embodiment the display unit 50 comprises three display elements in form of three LEDs 52, 54, 56 each one of which corresponding to a predefined condition including pneumothorax, hemothorax and/or normal state of the chest.
