What is BiPAP? Bilevel positive airway pressure. It has EPAP (same as CPAP only different name) and IPAP. EPAP: expiratory positive airway pressure. IPAP: Inspiratory positive airway pressure. BIPAP has the same benefits of CPAP. CPAP basically prevents you from exhaling all the way‚ and works to keep your lungs open to improve oxygenation‚ and it also keeps your upper airway open to prevent apnea BiPAP also adds a boost of air while you are inhaling -- which is what we call IPAP.

blood pressure. Blood pressure is measured by “the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure)” (American Heart Association [AHA]‚ 2008‚ para. 1). An average healthy adult’s blood pressure has a measurement of 120 over 80 or less (AHA‚ 2008‚ para. 3). “High blood pressure (also called hypertension) occurs when your blood moves through your arteries at a higher pressure than normal” (AHA‚ 2006‚ para. 1).High blood pressure occurs

that operate using more than one switches; mostly done to change the states of light (Brain‚ 2009). Grounded conductors method is when the switch does not disconnect the grounded conductor of the circuit. The switches controlling light loads are supplied by a grounded general purpose circuit and are connected such that the circuit conductor is available at the switch location (NFPA‚ 2011). The wall switches have to be located in quickly accessible places‚ they have to be installed such that the highest
