Hypercarbia ensues as the work of breathing
continues to increase.
The work of breathing
has been demonstrated to be comparable and not statistically significant between ETT and tracheostomy tubes (11).
Continuous positive airway pressure reduces work of breathing
and dyspnea during weaning from mechanical ventilation in severe chronic obstructive pulmonary disease.
Almost always supplemental oxygen is necessary to ensure adequate oxygenation to all the tissues of the body and to diminish the child's work of breathing
If you congest your nose, you can increase your work of breathing
by two or three times.
Esteban et al 2000) The primary objectives of mechanical ventilation are improvement of alveolar ventilation, decreasing the work of breathing
and reversing life threatening hypoxemia or acute respiratory acidosis (Tobin 2001).
The reported therapeutic goals of breathing control include correcting abnormal chest motion, reducing the work of breathing
and sensation of dyspnoea, improving the efficiency of breathing, and altering the distribution of ventilation (Miller 1954, Cahalin et al 2002).
Although subjectively we did not find the work of breathing
required with the prototype mask to be different from that required with a standard N95 filtering facepiece, persons with respiratory compromise of any type should not use this mask.
Lungs: Inspiratory and expiratory wheezing bilaterally; diminished breath sounds throughout all lung fields; increased work of breathing
O'Kroy and the team of researchers found no significant differences between the placebo and the active nasal dilator regarding the total work of breathing
The accessory muscles are not normally used during quiet respiration but can be called into "back up" service either when the diaphragm is impaired or when the work of breathing
is significantly increased.
The goal--and this is crucial--is to titrate to a dosage that will relieve the patient's subjective sense of the work of breathing
, not to reduce the respiratory rate.
