Pulmonary drug delivery is a route of administration in which patients use an inhaler to inhale their medications and drugs are absorbed into the bloodstream via the lung mucous membrane. This technique is most commonly used in the treatment of lung diseases, for example, asthma and chronic obstructive pulmonary disease (COPD) .
The model had its inception in 1964 when Roy was a graduate student. She was challenged by nursing faculty member Dorothy E. Johnson to develop a conceptual model for nursing practice. Roy's model drew heavily on the work of Harry Helson, a physiologic psychologist. [3]
The original purpose of the model was to be an assessment used throughout the patient's care, but it has become the norm in UK nursing to use it only as a checklist on admission. It is often used to assess how a patient's life has changed due to illness or admission to hospital rather than as a way of planning for increased independence and ...
MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...
The physical examination to diagnose cardiac arrest focuses on the absence of a pulse. [30] In many cases, lack of a central pulse (carotid arteries or subclavian arteries) is the gold standard. Lack of a pulse in the periphery (radial/pedal) may also result from other conditions (e.g. shock) or be the rescuer's misinterpretation.
Drug delivery systems have been around for many years, but there are a few recent applications of drug delivery that warrant 1. Drug delivery to the brain: Many drugs can be harmful when administered systemically; the brain is very sensitive to medications and can easily cause damage if a drug is administered directly into the bloodstream.
Patient care conference; Written nursing care plan; The greatest single distinguishing feature of team nursing is the team conference. In general, there are three parts to the conference; Report by each team member on his or her patients. Planning for new patients and changing plans as needed for others. Planning the next day’s assessment.
A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.
