BACKGROUND Ventilation during neonatal resuscitation is typically initiated with a face mask, but may be ineffective due to leak or obstruction. OBJECTIVE To compare leak using three methods of mask hold. METHODS Medical and nursing staff regularly involved in neonatal resuscitation used the three holds (two-point, two-handed, spider) on a manikin in a random order to apply positive pressur...

A set of equipment for an obstetric flying squad is described. It is aimed at providing the sequence: pre-oxygenation, intravenous barbiturate, suxamethonium, endotracheal tube, nitrous oxide, oxygen, intermittent suxamethonium and intermittent positive pressure respiration. A certain amount of variation in technique is also allowed for. Details of thirty emergency cases anaesthetized with the ...

Quadrupedal mammals typically synchronize their respiration with body movements during rhythmic locomotion. In the rat, fast respiration is coupled to head movements during sniffing behavior, but whether respiration is entrained by stride dynamics is not known. We recorded intranasal pressure, head acceleration, instantaneous speed, and ultrasonic vocalizations from male and female adult rats w...

Recently, the number of health-related car accidents in Japan has been increasing. Most health conditions leading to traffic are detectable by analyzing fluctuation blood pressure. In addition, cardiopulmonary arrest is an important condition that linked and should be studied along with respiration. Therefore, this study proposes a noncontact measurement system for cardiac dynamics respiration ...

THE technique of controlled respiration during anaesthesia was developed primarily to deal with respiratory inadequacy enforced on the patient by an open pneumothorax. This paper is concerned with developing means to adjust the volume of passive ventilation to a physiological level, the basis at present appearing to be entirely empirical. Originally, in order to institute controlled respiration...

Deadspace was measured in nine healthy subjects in the supine position, premedicated but awake and breathing spontaneously at a rate of 12 b.p.m. and subsequently under anaesthesia with artificial ventilation with frequencies of 12 and 24 b.p.m. The minute volume was kept at a relatively constant value. The physiological deadspace was calculated using the Bohr equation and the division into ana...

Cheyne-Stokes respiration is an abnormal breathing pattern which commonly occurs in patients with decompensated congestive heart failure and neurologic diseases, in whom periods of tachypnea and hyperpnea alternate with periods of apnea. In the majority of these patients, the ventilatory patterns may not be recognized, and the clinical features are generally dominated by the underlying disease ...

Three types of positive pressure breathing have been differentiated : a) continuous positive pressure breathing where a pressure above atmospheric is maintained in the lungs throughout the respiratory cycle, b) expiratory positive pressure breathing in which a pressure above atmospheric is present during the expiratory phase of breathing, and c) intermittent positive pressure breathing (IPPB), ...
