An increase of the ATM to 2 Bar (equal to conditions experienced during underwater diving at 10 meters) modestly but significantly decreased the IOP independently of the temperature change. The temperature increase alone did not significantly influence the IOP.Ĭonclusions. The IOP decrease remained constant during the ATM increase period (40 minutes) and was independent of the temperature change. The mean IOP decreased significantly from 11.8 mm Hg in the right eye (RE) and 11.7 mm Hg in the left eye (LE) at 1 Bar to 10.7 mm Hg (RE) and 10.3 mm Hg (LE) at 2 Bar ( P = 0.024, RE P = 0.0006, LE). Multivariate regression analysis was used to evaluate the results. Measurements were taken at baseline (normal ATM, 1 Bar and 24☌), at 28☌ and 24☌ after the ATM was increased to 2 Bar in a hyperbaric chamber, at baseline again, and finally at the normal ATM of 1 Bar but a temperature of 28☌. The IOP of 27 healthy volunteers (ages, 23.8 ± 4.9 years range, 18–44) was measured with a Perkins applanation tonometer by two independent investigators who were masked to the previous measurements. (d) At P652 mmHg it is necessary to add heat to achieve the equilibrium. P1 1 atm, z1 0, u1 0 Point 2 - pipe outlet. 5 L 100 0 mm Hg 1 atm 8.314 J (b) Flow work: V&P 66.7 J min min 760 mm. If the pressure on 6 Liters of gas is increased from 2 atm to 3 atm, what is the new. A balloon is filled with 652 mL of helium at a pressure of 1.00 atm. To determine whether the atmospheric pressure (ATM) change experienced during diving can induce changes in the intraocular pressure (IOP) of eyes in a normal population. What volume is occupied by 1.38 mol of a gas at 25oC and 652 mm Hg.
