Nov 19, 2013 · Airway pressure = flow x resistance + alveolar pressure. So if the resistance is high (as with bronchoconstriction) then a high PIP will be required, but the pressure being delivered to the alveoli can still be reasonable. One way to determine alveolar pressure in a patient on volume control ventilation, is to look at the inspiratory pause ...Author: Tessa Davis

Sep 08, 2005 · Rationale for mechanical ventilation in severe asthma. When a patient with severe asthma does not respond adequately to medical therapy, prompt intervention in an effort to provide adequate oxygenation and ventilation by means of noninvasive positive pressure ventilation (NPPV) or invasive positive pressure mechanical ventilation is frequently life saving.Cited by: 72

Oct 20, 2019 · Controlled ventilation is the preferred way to ventilate patients with asthma initially, because they require deep sedation to tolerate the necessary ventilator settings.

Oct 02, 2013 · Mechanical ventilation in patients with chronic obstructive pulmonary disease and bronchial asthma. ... non-invasive positive-pressure ventilation (NPPV) is the first line of treatment for these patients, but invasive positive-pressure ventilation may also be required in patients who have more severe disease. ... the use of PEEP during total ...Cited by: 5

We report the effect of pressure support ventilation (PSV) on auto-PEEP in a patient with asthma. The patient showed a high level of auto-PEEP during spontaneous breathing through a T-piece. PSV effectively decreased auto-PEEP and inspiratory muscle effort with increasing levels of PSV.Cited by: 14

Jun 01, 2010 · This forced me to realize that there is one ventilator prescription that will provide safe, idiot-proof ventilation for most COPD/asthma patients… a universal vent prescription. It is Pressure Control mode with 5 cm PEEP, 30 cm Pressure Support, 60% FiO2, respiratory rate of 14/min (to generate a peak pressure of 35cm).

Evidence for ventilation in asthma is limited but it is intuitive from the above points that ventilation should therefore comprise low tidal volumes, a low respiratory rate and a prolonged expiratory time while maintaing an acceptable pH (permissive hypercapnia is discussed in another case history) and oxygenation (which is rarely a problem).

Continuous recordings of flow, airway pressure, and esophageal pressure during pressure support ventilation at 0, 5, and 10 cm H 2 O in a patient with asthma. Auto-PEEP and fluctuation of esophageal pressure were minimal at pressure support ventilation 10 cm H 2 O.Cited by: 14

airway pressure ventilation or pressure support ventilation (PSV). The effect of PSV on auto-PEEP is also unclear. We report the effect of PSV on auto-PEEP in a patient with asthma. CASE REPORT A 77-yeaN>ld woman with a history of asthma was admitted to our hospital for a …
