Hearing loss during resuscitation

|June 1, 1975
Summary
Positive pressure mask ventilation can rarely cause tympanic membrane injuries. Two patients experienced partial deafness due to incudomalleal joint disarticulation or oval window perilymph fistula from excessive pressure.
Area of Science:
- Otolaryngology
- Emergency Medicine
- Audiology
Background:
- Positive pressure ventilation via mask is a critical resuscitation tool.
- Tympanic membrane and middle ear injuries are uncommon complications.
- Understanding the mechanisms of barotrauma is essential for patient safety.
Purpose of the Study:
- To report rare cases of tympanic injury from positive pressure mask ventilation.
- To investigate the potential causes of hearing loss in patients undergoing resuscitation.
- To highlight the risk of barotrauma to the middle ear.
Main Methods:
- Case report of two patients experiencing hearing loss post-ventilation.
- Clinical examination and audiological assessment.
- Review of pressure dynamics and anatomical pathways.
Main Results:
- Two patients developed partial deafness following mask ventilation.
- One patient had incudomalleal joint disarticulation.
- The other patient presented with an oval window perilymph fistula.
Conclusions:
- Excessive, rapid pressure transmission through the eustachian tube is the likely cause.
- These injuries underscore the potential for barotrauma during resuscitation.
- Awareness and careful pressure management are crucial to prevent such adverse events.

01:23Assessment of Respiration
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 asthma or COPD,...

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:24Endotracheal Tube Extubation
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.

01:21Cardiopulmonary Resuscitation I: Adult
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...
01:22Cardiopulmonary Resuscitation II: ACLS Airway Management
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 under...
01:23Cardiopulmonary Resuscitation III: AED Use
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
