Each study compared performance at a minimum of two different ventilation rates.
Methods: During the 8-month study of sequential design, 176 patients were admitted, 65 (37%) of whom required a minimum of 3 days of ventilation.
It was found that for the use of a minimum ventilation rate of 10.3 L/s/person, the use of desiccant cooling system as compared to conventional system saved 4% of the energy and could achieve the desired space conditions.
Legislation impinges upon health in various ways, including the provision of safety measures, the restriction of pollution, and the enforcement of minimum standards of lighting, ventilation, and space per person.
Average values of maximal P L and the mean P L during PC-IMV were significantly lower when compared to PC-CMV (p = 0.006) and PC-SIMV (p = 0.004), but no difference in minimum P L during each mode of ventilation was found (Fig. 3).
Thus, this E drs map outlines a potential drawback of ventilation considering only minimum elastance.
Also, the Egyptian Energy Code for residential buildings implies a minimum natural ventilation rate of 3 L/s-person (10.8 m3/h) for the living room [30].
Besides the current approach of setting minimum ventilation standards to prevent health effects due to indoor air pollution, a standard based on the olf or decipol unit might be more efficacious as well as simpler to measure.
PC-CMV pressure-controlled continuous mandatory ventilation, PC-SIMV pressure-controlled synchronized intermittent mandatory ventilation, PC-IMV pressure-controlled intermittent mandatory ventilation Fig. 3 Maximal, mean, and minimum transpulmonary pressure (P L ) during the three pressure-controlled modes of ventilation.
Ventilation parameters (VT, RR, PEEP), respiratory compliance, driving pressure, arterial blood gases, and ECCO2R system operational characteristics (blood flow, sweep gas flow, and CO2 removal rate) were collected during a minimum of 24 h of ultra-protective ventilation.
