SPO₂, respiratory rate and heart rate were recorded every minute for a 10 min period and classified according to most frequent category of observations present for >5 min. c. Upper limit of SPO₂ for providing oxygen therapy was 95%. Abbreviations: bCPAP= Bubble continuous positive airway pressure; RR=Respiratory rate; h=hours; HR=Heart rate; SPO₂=oxygen saturation.
