- What is the total flow for a 35% venture mask set at 10 liters per minute at the flow meter?Blood plasma flows with a rate of 0.4 cm³/s through a tube with a diameter d = 0.18 cm and length 1 = 1.8 m at a temperature of 20°C. The pressure at the tube entrance is P2 = 1.48 x 104 N/m2. If the temperature of the tube and plasma reaches 29°C, what is the tube entrance pressure P2' needed to maintain the flow rate and pressure at the tube exit constant. Consider 120°c = 1.81 mPa·s and n29°c = 1.28 mPa.s.Nizatidine injection (25 mg/mL) is supplied in 4-mL vials. The prescription states that for continuous infusion 'dilute 300 mg in 150 mL and give at a rate of 10 mg/hour'. If this procedure is adopted, calculate: (a) how many vials of nizatidine injection will be required (b) the flow rate (in mg/hour). NOTE: PLEASE GIVE THE ANSWER WITHIN 2 HOURS THANK YOU

If the pressure in your vein is 15 torr, what is the minimum height required for infusing the saline into the vein at a pressure of 20 torr above the pressure in the vein (assume rsal = 1 kg/L). Note: ignore the pressure drop in the %3D injection needle! O 55 cm O 48 cm O 23 cm O 66 cm O 74 cm O 35 cm
- Total blood volume in the capillary tube is 20mm, the packed cell volume(red blood cells) is 7.1 mm, and the plasma portion measures 12.9mm. How is hematocrit calculated?Is 100/60 mmhg a normal blood pressure or low blood pressure (hypotension) ? Please explain.750mL is being infused at a rate of 45 gtt/min. The drop factor is 20gtt/mL. How many mL per hour will the patient receive?
- Systemic blood pressure is defined as the ratio of two pressures—systolic and diastolic—both expressed in millimeters of mercury. Normal blood pressure is about 120mm/80mm which is usually just stated as 120/80. What would normal systemic blood pressure be if, instead of millimeters of mercury, we expressed pressure in each of the following units, but continued to use the same ratio format? Part A) atmosheres = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part B) torr = a) 120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part C) Pa = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part D) N/ m^2 = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part E) psi = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4Using a prescribed fluid delivery rate of 5 mL/kg/hr during the first hour of anesthesia, and a macrodrip delivery set with a delivery rate of 15 gtt/mL, a 53 lb patient would require which of the following infusion and drip rates?265 mL/hr; 1 gtt/sec121 mL/hr; 1 gtt/sec121 mL/hr; 1 GTT/2 sec121 mL/hr; 1 gtt/4 secThe physician ordered an infusion of NSS 500 millimeters in 3 hours using a 15 drops/mL set. With 1 ½ hours remaining, you discover that only 150 millimeter is left in the bag. At what rate in drops per minute will the infusion be reset?
