30. Convert 30°C to Kelvin
Formula = 30 + 273.15 = 303.15K
31. Convert 68°F to Celsius
Formula = F - 32 × 5/9
= 68- 32 ×5/9
= 36× 5/9
= 20°C
32. Convert 40°C to Fahrenheit
Formula = C×9/5+32
= 40× 9/5 + 32
= 104°F

A patient with COPD has an arterial blood gas (ABG) content of 65 mm Hg. A normal ABG oxygen level ranges between 80 and 100 millimeters of mercury (mm Hg). If you send this patient to the hyperbaric chamber what oxygen pressure do you need to program the machine to bring the ABG content to 90 mm Hg. (assume your patient is the average human) Additional information: The average human has 3 liters of blood. Body temperature is 37 C....

1.) Charles Law states: volume and temperature are directly proportional when pressure remains constant 2.) Boyle's Law states:_pressure and volume are inversely related when temperature remains constant 3.) What is the relative humidity of inspired gas in a person's airway if the water vapor content breathed in is 30 mg/L at normal body temperature? 30/44x100=68% 4.) Calculate the FEV1%. FVC is 6L and FEV1 is 4L 4/6=0.67 or 67% 5.) True or False: Vital Capacity is Total Lung Capacity -...
