22
Q
Process of ventilation
A
- the diaphragm contracts and descends, lengthening the thoracic cavity
- the external intercostal muscles contract, lifting the ribs upwards and outwards
- the sternum is pushed forward, enlarging the chest from front to back
- increased lung volume and decreased intrapulmonic pressure allow air to move from an area of greater pressure (outside lung) to lesser pressure (inside lungs)
- the relaxation of these structures results in expiration
23
Q

- res rate is rapid and res activity is primarily abdominal
Synthetic surfactant can be given to infants to reopen alveoli
Crackles heard at end of deep respiration are normal
48
Respiratory activity in the child
- some subcutaneous fat is deposited on the chest walls making landmarks less prominent

- tissues and airways become more ridged; diaphragm moves less efficiently
- ^ risk for disease, especially pneumonia
51
