Combined Pressure Control/High Frequency Ventilation in Adult Respiratory Distress Syndrome and Sickle Cell Anemia: Case Report

He developed worsening respiratory distress and was intubated (Fig 1) and given conventional positive pressure ventilation in the pressure control mode (Siemens-Elema Servov-entilator 900C, Sweden). Peak inspiratory pressure (PIP) was 36 cm H2O, PEEP was 5 cm H2O, the fractional … Continue reading

Combined Pressure Control/High Frequency Ventilation in Adult Respiratory Distress Syndrome and Sickle Cell Anemia

Patients with sickle cell disease-related acute chest syndrome often progress rapidly to adult respiratory distress syndrome (ARDS), necessitating endotracheal intubation and positive pressure ventilation. Aggressive intensive care, including the judicious use of positive end-expiratory pressure (PEEP), has not substantially changed … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Finally

Mask or mouth leaks may also have a negative effect on gas exchange and impair the effectiveness of NPPV in avoiding endotracheal intubation. In studies examining NPPV in acute respiratory failure, inability to improve gas exchange, or poor patient tolerance … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Comment

In addition, there are two small bore orifices in the superior aspect of the mask to act as exhalation valves. In patients discharged home from the hospital with the mask, oxygen was administered by a compressed gas source to ensure … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Conclusion

Schwartzstein et al have shown a significant reduction in the sensation of dyspnea when normal subjects have cold air directed to the cheeks while breathing against an inspiratory resistive load. Di-Giorgio and Giulio showed similar results in normal subjects breathing … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Discussion

There was a significant improvement in gas exchange short term during NPPV with all three masks; however, the reduction in PaCC>2 was greatest when NPPV was delivered with the TFM. This is attributed to the observation that the increases in … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Side Effects of the TFM

A representative tracing of airway pressure, airflow, and tidal volume for one patient while receiving NPPV is shown in Figure 4. Panel A shows the inability to maintain the preset pressure because of air leakage via the mouth during NPPV … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Results

Arterial blood gas analysis for each patient while breathing spontaneously and during NPPV with each of the three masks is shown in Figure 2. The mean PaC>2/Fl02 values during NPPV with each of the masks were higher (360 ±25, N; … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Statistical Analysis

After initial titration of pressure (BiPAP) or volume (PLV-102), to achieve ventilation goals as previously outlined, levels of ventilation remained identical during each trial with the three different face masks. At the end of each trial, arterial blood gas analysis … Continue reading

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: Masks for NPPV

Patients were chosen to receive the ventilatory support system or noninvasive ventilation via a volume ventilator based on their degree of comfort with each mode, and the ability to increase minute ventilation and improve gas exchange. After the initial evaluation … Continue reading
