Nasal insufflation treatment adherence in obstructive sleep apnea
Sleep & Breathing = Schlaf & Atmung
|July 13, 2014
Summary
Nasal insufflation (NI) and continuous positive airway pressure (CPAP) showed similar adherence for mild to moderate obstructive sleep apnea (OSA) over a short period. Further trials are needed to confirm NI
Area of Science:
- Sleep Medicine
- Respiratory Therapy
Background:
- Nasal insufflation (NI) offers a novel approach to respiratory support during sleep.
- NI delivers warmed, humidified airflow with potentially improved tolerability due to minimal side pressures.
Purpose of the Study:
- To compare objective and subjective adherence rates of NI therapy versus continuous positive airway pressure (CPAP) in patients with mild to moderate obstructive sleep apnea (OSA).
Main Methods:
- A crossover study involving 10 patients (3 men, 7 women) with mild to moderate OSA.
- Adherence was assessed using objective measures (sleep efficiency, arousal indices, time on therapy) and subjective reports (sleep diary) over a short treatment period.
Main Results:
- Objective adherence was comparable between NI and CPAP, with similar nightly usage and duration of treatment.
- Self-reported adherence was significantly higher than objectively measured adherence.
Conclusions:
- NI demonstrates similar short-term adherence to CPAP in patients with mild to moderate OSA.
- A randomized clinical trial is necessary to establish the comparative effectiveness of NI therapy against CPAP.

Administering Oxygen by Nasal Cannula
6.0K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

Sleep Apnea
909
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Suctioning the Nasopharyngeal Airway
6.4K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Cardiopulmonary Resuscitation II: ACLS Airway Management
1.2K
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Mechanical Ventilation III: Noninvasive Ventilation
922
Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Oxygen Delivering System I: Nasal Cannula and Face Mask
2.7K
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:...
