RR: an increase in respiratory rate indicates possible airway disease or metabolic acidosis. Conversely, a slow respiratory rate can be an ominous sign indicating breathing fatigue, cerebral depression or a pre-terminal state. Reccesion: as paediatric patients have a more compliant chest wall (that is, it is not as rigid as an adults) any increased negative pressures generated in the thorax will result in intercostal, sub-costal or sternal recession. Greater recession = greater respiratory distress. But be careful, as children will tire from an increased effort of breathing much faster than adults, and as they do, these recessions will decrease. Accessory muscles: the child may begin using the sternomastoid muscle to assist with breathing. In infants this may lead to bobbing of the head. Looks cute, but isn’t. Grunting: a grunting child is a bad thing. It is an attempt to keep the distal airways open by generating a grunted positive end-expiratory pressure. It is a sign of severe respiratory distress. Grunting may also be seen in children with raised intercrainial pressure. Alar nasal flare: increase diameter = increased volume
Stridor: is usually more pronounced in inspiration but may also occur during expiration. It indicates an upper airway obstruction. Always consider the possibility of an inhaled foreign body if you can hear stridor. Wheeze: Indicates lower airway narrowing and us usually more pronounced during expiration. Increased wheeze does not = increased respiratory distress. And once again, wheeze will subside as the patient becomes exhausted. Rhonchi: course rattling sound, somewhat like snoring, usually caused by secretions in the brhonical airways
Efficacy: capacity to produce an effect Chest expansion: symetrical Air entry: equal, no adventious (added) sounds Pulse oximetry: random number generators, they rely on many things to work, such as peripheral circulation, warmth, constant waveform.
