WebOct 18, 2014 · When considering possible reasons why ventilation is not improved post-intubation, you need to think in terms of mechanical obstruction, mechanical malfunction, and pressure. The leading possibilities for why this patient cannot be adequately bagged after intubation are: 1) Auto-PEEP (“breath stacking”) 2) Tension pneumothorax
WebDec 27, 2024 · Breath Stacking/Auto-Peep = occurs when air flow does not return to zero at end-exhalation. This is often seen in patients with COPD during spontaneous breathing. BASICS: When ventilation is the issue (ex, hypercapnia in patient with COPD or sepsis), consider changing the: Respiratory rate- RR has an inverse relationship with CO2. WebPatient–ventilator dyssynchrony occurs when mechanical support from the ventilator does not match the neuromechanical output from the patient’s respiratory center. ...
