|
The primary ventilator strategy for patients with severe obstructive lung disease
|
to allow adequate time for exhalation before the next delivered breath and to minimize auto–positive end-expiratory pressure (auto-PEEP)
|
|
|
Ventilation strategies that increase expiratory time
|
decreasing the tidal volume and respiration rate increasing inspiratory flow rates judicious use of sedation and analgesia |
|
|
sequelae of auto-PEEP
|
increases in end-expiratory pressures decreased venous return hypotension barotrauma |
|
|
mechanisms of bicarbonate therapy in TCA overdose
|
not well described, it is believed that the increased serum pH minimizes binding of the drug to sodium channels and that the increased serum sodium concentration alters the gradient across sodium channels, decreasing the risk of arrhythmic potentials in the myocardium
|
|
|
pregnancy classification of long-acting β2-agonists
|
pregnancy category C, meaning evidence of safety is lacking but the potential benefit of the drug may justify the potential risk
Despite this, the addition of a long-acting β2-agonist is recommended when symptoms are not controlled with medium-dose inhaled corticosteroids because the addition of this medication results in better asthma control compared with doubling the dose of inhaled corticosteroids |
|
|
Potential clues for vocal cord dysfunction |
sudden onset and abrupt termination of attacks, lack of response to asthma therapy, prominent neck discomfort, and lack of hypoxemia |
