The invention also relates to an optical sensor for a photoplethysmography measurement, comprising a light unit (1) with a light emitter (2) for emitting light into tissue of a patient (8) and/or a light detector (3) for detecting a part of the emitted light after interaction with the tissue, wherein the light unit is embedded in an elastic material (4). The invention further relates to a device for contactless respiration monitoring of a patient (8), comprising: a distance sensor for consecutively detecting the temporal distance variations relative to the patient's chest (12), preferably based on electromagnetic waves; and a calculating unit for determining the breathing activity based on the detected temporal distance variations. The invention is especially useful for providing a reliable and easy to use possibility for simultaneously monitoring respiration action, blood pressure and heart rate with a handheld device which can be used for spot- checking the vital parameters of patients ...
