    As neonatal heart rate (HR) is a vital sign used to assess the need for and response to resuscitation,1 measuring it rapidly, accurately and affordably is important to clinicians around the world. We aimed to assess the accuracy, speed and reliability of a novel low-cost digital stethoscope (DS) attached to a smartphone running real-time newborn HR detection software in determining the HR of clinically stable infants.

    We studied infants >26 weeks’ corrected gestation excluding those receiving high-frequency oscillation ventilation. We applied the Stethocloud V.0.2beta DS head to their exposed precordium. The DS was connected to an Apple iPhone 5s running Neorate 0.1a software (CliniCloud, Melbourne, Australia) which displayed a real-time HR (DS HR). …
