Yes, like hospital acquired infections ( UTI, Hospital Acquired Pneumonia, Critical care neuropathy, ICU psychosis etc.

It is a gadget to measure(noninvasive) the oxygen saturation in our body. During a pulse oximetry reading, a small clamp-like device is placed on a finger, earlobe, or toe. Small beams of light pass through the blood in the finger, measuring the amount of oxygen. It does this by measuring changes of light absorption in oxygenated or deoxygenated blood. This is a painless process.
