Apnea Monitoring in Pediatric Care
Apnea Monitoring in Pediatric Care
An apnea monitor is a specialized medical device designed to track breathing patterns in infants and alert healthcare providers or caregivers when breathing pauses occur. These devices are crucial in preventing Sudden Infant Death Syndrome (SIDS) and managing respiratory conditions.
Key Features
- Continuous respiratory monitoring
- Heart rate monitoring capabilities
- Oxygen saturation measurement (in advanced models)
- Multi-parameter alarm systems
- Data storage and trending
- Portable design for home use
Primary Functions
- Detection of central apnea
- Identification of obstructive apnea
- Mixed apnea recognition
- Bradycardia detection
- Real-time vital sign trending
