Figure 3From: Effects on heart pumping function when using foam and gauze for negative pressure wound therapy of sternotomy wounds Change in central venous pressure and left atrial pressure upon the application of NPWT at -120 mmHg, using foam and gauze (n = 8). Before negative pressure was applied, baseline left atrial pressure was 6.3 ± 0.2 mmHg and central venous pressure was 4.8 ± 0.1 mmHg. Results were similar at the other negative pressures studied (not shown).Back to article page
