Is there more pressure used in Osmosis or reverse Osmosis?
Water or liquid move naturally from lower concentration to higher concentration. The drive force is called osmotic pressure. No additional pressure need to drive osmosis process. Reverse osmosis, is apply pressure to fight against osmotic pressure. It do need additional pressure to reverse the osmosis process. It is comparing a zero additional pressure with any positive additional pressure thus of cause reverse osmosis require more pressure.
What is the different between turgor pressure and diffusion?
The difference of turgor pressure and diffusion is that turgor pressure is an osmotic pressure exerted by the contents of a plant cell against its cell wall; while diffusion is a movement of molecules from an area higher concentration to an area lower concentration.
6 ways to disturb a chemical equilibrium?
temperature pressure concentration
What are the factors that affect the products of a chemical equation?
temperature, pressure, concentration
What is osmosis pressure?
Its known is osmotic pressure When two solution of volumes are separated by a semi-permeable membrane, water will flow from the volume of low solute concentration, to the volume of high solute concentration. The flow may be stopped, or even reversed by applying external pressure on the volume of higher concentration. In such a case the phenomenon is called reverse osmosis. If there are solute molecules only in one volume of the system, then the pressure on it, that stops the flow, is called the osmotic pressure.
Is mouth to mouth resuscitation positive pressure inhalation?
Yes.
What are the signs that positive pressure ventilation has been effective and may be discontinued?
Positive pressure ventilation is the use of life sustaining systems to help individuals that are showing respiratory distress. The signs that positive pressure ventilation has been successful are breathing over the ventilator and blood gas labs that are in normal ranges.
What is a complication associated with positive-pressure ventilations?
The complication that is usually associated with the positive-pressure ventilation is that the lung can be injured.
Which finding is an indication for using positive-pressure ventilation?
Apnea or gasping
Which finding is an indication for using positive pressure ventilation?
Apnea or gasping
How positive pressure ventilation effect fi02?
positive pressue ventilation is usually provided by a mechanical ventilator. A blend of oxygen and air coming out of the ventilator. The FiO2 is set on the ventilator. The person gets the FiO2 set on the ventilator.The manual positive pressure ventilation is by resuscitating with a self inflating bag usually provided with oxygen. FiO2 is fractional inspired oxygen and does not change with positive pressure ventilation or negative pressure ventilation. Manual bagging FiO2 may be changing according to supply of oxygen, inhalation (speed and volume) and frequency of bagging.
What is positive airway pressure?
Continuous positive airway pressure (CPAP)-- A ventilation device that blows a gentle stream of air into the nose during sleep to keep the airway open.
What should you do if you get injured by a Cone Shell?
Pressure immobilisation first aid should be applied and left in place until resuscitation facilities are available. This is a medical emergency. Assisted ventilation may be needed.
What is continuous positive airway pressure?
Continuous positive airway pressure (CPAP)-- A ventilation device that blows a gentle stream of air into the nose during sleep to keep the airway open.
What is the most effective maneuver to establish normal breathing in a baby with secondary apnea?
application of positive-pressure ventilation
How does positive-pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
