Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen01:16

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

1.2K
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,...

Respiratory Assessment: Purpose and Indications

1.4K
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...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure

423
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Administering Oxygen by Mask01:30

Administering Oxygen by Mask

1.2K
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:

Special considerations while measuring oxygen saturation01:19

Special considerations while measuring oxygen saturation

779
Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.
Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is...

Oxygen Delivering System I: Nasal Cannula and Face Mask01:26

Oxygen Delivering System I: Nasal Cannula and Face Mask

964
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Area of Science:

  • Critical care medicine
  • Quality improvement science
  • Patient safety research

Background:

  • Iatrogenic hyperoxaemia is a common and potentially fatal issue in critical care settings.
  • Current practices often lack prescribed target oxygen saturation ranges for patients.
  • This study addresses the need for improved oxygen therapy management.

Purpose of the Study:

  • To analyze critical care staff perspectives and practices regarding oxygen therapy.
  • To implement and evaluate a quality improvement initiative for oxygen prescribing.
  • To ensure all critical care patients have a prescribed target oxygen saturation range.

Main Methods:

  • A pilot quality improvement study was conducted.
  • Baseline data on oxygen target range prescribing and staff attitudes were collected via surveys.
  • A structured protocol for oxygen prescribing was introduced and promoted, followed by repeat data collection.

Main Results:

  • The proportion of patients with a prescribed oxygen target range increased from 85% to 95% (p=0.02).
  • The percentage of patients with an appropriate prescribed oxygen saturation range rose from 85% to 91%.
  • This improvement in prescribing practice was maintained at 96% after 12 months.

Conclusions:

  • A structured protocol for oxygen prescribing effectively increased the proportion of patients with a prescribed target range.
  • The quality improvement initiative led to sustained positive changes in oxygen therapy management.
  • This approach enhances patient safety by ensuring appropriate oxygen saturation targets.
