“…Higher heart rates in subsequent SIDS infants when compared to controls have been found (37); the authors conclude that although monitoring lacks specificity, it was probably effective in preventing mortality in at risk groups. This phenomenon has been noted by other authors (38).…”

“…ignificant new information has been forthcoming in recent decades on sudden infant death syndrome (SIDS) and apnea during early infancy. [1][2][3][4][5][6][7][8] This statement focuses on the epidemiologic aspects of SIDS, the lack of a proven association between episodic apnea and SIDS, strategies for prevention of SIDS, and appropriate use of home cardiorespiratory monitoring.…”

“…The apnea theory never has been proven despite extensive independent research in the several decades after that report. [1][2][3][4][5] Nevertheless, the home cardiorespiratory monitoring industry, fueled by increasing demand from parents concerned about the risk of SIDS, rapidly developed products aimed at preventing SIDS. 11 Despite the absence of a scientific foundation or evidence of efficacy, 12,13 home cardiorespiratory monitoring continues to be a common practice in this country.…”

More than 25 years have elapsed since continuous cardiorespiratory monitoring at home was suggested to decrease the risk of sudden infant death syndrome (SIDS). In the ensuing interval, multiple studies have been unable to establish the alleged efficacy of its use. In this statement, the most recent research information concerning extreme limits for a prolonged course of apnea of prematurity is reviewed. Recommendations regarding the appropriate use of home cardiorespiratory monitoring after hospital discharge emphasize limiting use to specific clinical indications for a predetermined period, using only monitors equipped with an event recorder, and counseling parents that monitor use does not prevent sudden, unexpected death in all circumstances. The continued implementation of proven SIDS prevention measures is encouraged.

Progressive Shortening of the Periodic Breathing Cycle Duration in Normal Infants

ABSTRACT. Ten normal full-term neonates were monitored by oxycardiorespirography in hospital during the 1st wk of life, and subsequently at home at 4, 8, and 12 wk of age in a longitudinal study of the duration of the periodic breathing cycle during spontaneous sleep. Periodic breathing was observed in 25 of the 40 studies, with a total of 168 epochs of periodicity noted. Eighty-four percent of the periodic epochs occurring during nonrapid eye movements were preceded by a sigh, body movements, or sleep state transition, compared with 41 % during rapid eye movements (p < 0.005). There was a progressive reduction in the periodic breathing cycle duration, which fell significantly between the 1st and 4th wk, in both sleep states, ( p < 0.001). There was a further significant fall between 4 and 12 wk in nonrapid eye movement sleep ( p < 0.05), and there was no significant difference between sleep states at any postnatal age. The overall change in the duration of the periodic cycle, for both sleep states combined, was from 15.0 f 3.6 s at < 1 wk to 12.4 f 1.8 s at 12 wk of age. The periodic breathing cycle duration progressively shortens over the first 3 months of life. We postulate that this shortening may be a useful indicator of peripheral chemoreceptor maturation over this time period.

There has, however, been very little investigation of other features of periodic breathing, and no studies which have investigated the duration of the individual cycle, i.e. the time from the end of one periodic apnea to the end of the subsequent periodic apnea. The description of these features may be important in understanding the changes in respiratory control which are occurring during early infancy.In the newborn lamb during postnatal maturation, a progressive shortening in the time required for the carotid chemoreceptor to respond to a change in arterial oxygen tension has been demonstrated (9). We hypothesized that a reduction in the chemoreceptor response time should lead to a progressive shortening in the duration of the periodic cycle in normal newborn infants during the first 3 months of postnatal life. MATERIALS AND METHODSTen infants, delivered at the Royal Alexandra Women's Hospital, between 37 and 41 wk gestational age, birth weight appropriate for gestational age, without perinatal asphyxia or other pre-or perinatal complications, whose mothers were nonsmokers and resident within a 30 mile radius of Edmonton, were studied following informed parental consent. Infants were studied in the hospital within the first 7 days of life and subsequently at home at 4, 8, and 12 wk of age. In order to ensure that sleep was as normal as possible, all studies were performed during spo...
