Inhaled Medications01:23

Inhaled Medications

423
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Respiratory Assessment: Purpose and Indications

1.3K
Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

Assessment of Respiration01:23

Assessment of Respiration

1.3K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Pulmonary Ventilation: Inhalation01:24

Pulmonary Ventilation: Inhalation

4.9K
Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.
Boyle's law becomes particularly pertinent when examining respiratory...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

1.0K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Summary
This summary is machine-generated.

Patients struggle to determine when their metered dose inhalers (MDIs) are empty, leading to improper disposal. Improved inhaler technology and clear guidance are needed for accurate empty inhaler identification and safe disposal practices.

Area of Science:

  • Pediatric Respiratory Medicine
  • Pharmaceutical Technology
  • Quality Improvement Science

Background:

  • Medication review is a standard recommendation during asthma appointments.
  • Metered dose inhalers (MDIs) containing propellants pose challenges in determining when they are empty.
  • The COVID-19 pandemic accelerated the adoption of virtual care monitoring.

Purpose of the Study:

  • To assess patients' ability to identify when their metered dose inhalers (MDIs) are empty.
  • To evaluate current methods of inhaler disposal among pediatric patients.
  • To inform improvements in inhaler usability and patient guidance.

Main Methods:

  • A prospective, multicenter quality improvement project was conducted.
  • Data were collected from pediatric patients with asthma and other respiratory conditions.
  • Interviews with children and caregivers focused on identifying empty salbutamol inhalers, reviewing dose counters on preventer inhalers, and assessing disposal habits.

Main Results:

  • 157 patients were enrolled in the study.
  • A significant majority, 125 (73.5%), incorrectly identified empty inhalers as full or partially full.
  • Among preventer inhalers with dose counters, 12 of 66 (18.2%) were found to be empty.
  • Improper disposal was common, with 83% of inhalers discarded in dustbins.

Conclusions:

  • Patients demonstrate an inability to reliably determine when their metered dose inhalers (MDIs) are empty.
  • There is a critical need for advancements in MDI technology to facilitate accurate emptiness detection.
  • Clearer patient instructions and guidance are essential for managing empty inhalers effectively.
