Children and infants have respiratory and heart rates that are faster than those of adults as shown in the following table: Monitoring of vital parameters most commonly includes at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate. Multimodal monitors that simultaneously measure and display the relevant vital parameters are commonly integrated into the bedside monitors in intensive care units, and the anesthetic machines in operating rooms. These allow for continuous monitoring of a patient, with medical staff being continuously informed of the changes in general condition of a patient. While monitoring has traditionally been done by nurses and doctors, a number of companies are developing devices which can be used by consumers themselves. These include Cherish Health, Scanadu and Azoi.
