HEALTH PROBLEM ADDRESSED
Apnea monitors detect the cessation of breathing (apnea) in infants and adults who are risk of respiratory failure and alert the parent or attendant to the condition, some prolonged respiratory pauses result in low oxygen concentration levels in the body. Which can lead to irreversible brain damage and. If prolonged. Death.
The components of apnea monitors depend specifically in the type. However, in general they are composed of a set of sensors which obtain the information of different physiological parameters. This information is passed to a micro computer system, which analyes the sensors information and determines if apnea is occurring.
PRINCIPALES OF OPERATION
Monitors that use impedance penumography detect small changes in electrical impedance as air enters and leaves he lungs and as the blood volume changes in the thoracic cavity. Mattress-type motion sensors typically monitor changes in the capacitance or resistance of matters transducer. Pneumatic abdominal sensors, thmistors, proximal airway pressure sensors, carbon dioxide (co2) sensors, cannula) once connected, as the patient breathes, the unit monitors different body parmeters. If an alarm sounds, operators must attend the patient immediately.
Apnea monitors may fail to alarm during an episode because they sense artifact (artifacts include vibration, heart activity, patient movement) electromagnetic emissions from electronic devices (other electronics or equipment) can also cause interference. Possibly leading to false breath and heartbest detection, impedance anemographs are more subjects to cardiovascular artifact. Misinterpreting impedance change because of heartbeats perceived as breath frequent when instrument sensitivity is not adjusted.
