An arterial blood gas (ABG) is a blood test that is performed using blood from an artery. It involves puncturing an artery with a thin needle and syringe and drawing a small volume of blood. The test is used to determine the pH of the blood, the partial pressure of carbon dioxide and oxygen and the bicarbonate level. Arterial Blood Gas Testing is a 24 hours service that caters our In-patient and Out-Patient.

Peak Expiratory Flow rate (PEFR) Indicated in patients with bronchial spasm to check the lung airway response in a given bronchodilator medication. It is use to detect impending attack in patients with Bronchial Asthma. It is commonly ordered before and after giving fast acting bronchodilator medications. Using the Peak Expiratory Flow meter patient is instructed to forcefully blow on the meter to measure PEFR.

Pulmonary function tests (PFT) are a group of procedures that measure the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases, such as asthma, bronchitis or emphysema. Asian Hospital is also providing Pulmonary Function Test on-site. This PFT can be conduct in the working place of a company for their Annual Physical Examination.

Impulse Oscillometry (IOS) is a test involving simple normal breathing maneuvers to diagnose certain lung diseases. .  It is especially useful for pediatric and elderly populations who may not be able to follow instructions involving more vigorous performance needed in spirometry.

Rapid shallow breathing index (RSBI) is indicated to a patient hooked to a ventilator to help clinician determine patienst readiness in weaning to a mechanical ventilator. Also use in spontaneously breathing patient to determine vital capacity. A “Wrights Spirometer is use to measure the values.

Pulse Oximetry is a simple and non-invasive technique to monitor oxygenation. It monitors the percentage of hemoglobin that is oxygen-saturated.

Ventilator Management is services that provide a mechanically assisted breath to patients. This may involve a machine called a ventilator or the breathing may be assisted by a respiratory therapist, or other suitable person compressing a bag valve mask. There are two main types of mechanical ventilation: invasive ventilation and non-invasive ventilation. There are two main modes of mechanical ventilation within the two divisions: positive pressure ventilation, where air (or another gas mix) is pushed into the trachea, and negative pressure ventilation, where air is essentially sucked into the lungs.

CPAP / BIPAP Management is the application of positive pressure to the airways of spontaneously breathing patients. It is a non-invasive method for the treatment of respiratory failure and a recommended therapy for patients with Obstructive Sleep Apnea.

 Nebulization is the process of medication administration via inhalation. It utilizes a nebulizer which transports medications to the lungs by means of mist inhalation.

Carbon Monoxide measurement is a measurement of carbon monoxide thru a patient breath. This service is use in the Smoking Cessation program of the unit.

Critical Congenital Heart Defect Screening is a service provided to newborn for screening of heart defect. Oxygen saturation is measured to a specific site after 24-48 hours of delivery.

Oxygen Therapy is the administration of oxygen as a medical intervention, which can be for a variety of purposes in both chronic and acute patient care. Oxygen is essential for cell metabolism, and in turn, tissue oxygenation is essential for all normal physiological functions. Asian Hospital has its safety system in Oxygen delivery. The hospital is equipped of Bulk system Liquid oxygen to provide continuous flow of Oxygen to all.

Incentive Spirometry (IS) indicated to patient to prevent and treat Atelectasis. The goal is to promote lung expansion with special consideration to patients for surgery were they be instructed prior to their surgical procedure to enable them in using the I.S properly/correctly.

Chestphysiotherapy (CPT) is a process of application of mechanical energy in the chest wall using mechanical percussor to: Prevent accumulation of secretion, Improve the mobilization of secretion, Promote more efficient breathing patterns, Improve the distribution of ventilation, Improve cardiopulmonary exercise tolerance.

Sleep Laboratory

The Sleep Laboratory of Asian Hospital and Medical Center provides treatment geared towards reducing socially unacceptable snoring to obstructive sleep apnea.

The Sleep Laboratory Services has 2 bedrooms that perform nocturnal overnight sleep tests. However, if the patient is a shift-worker and normally sleeps in the daytime, they are accommodated during the daytime as well.

Sleep Study or Polysomnography (PSG)

A type of sleep study, a multi-parametric test used in the study of sleep and as a diagnostic tool in sleep medicine, the test result is called a plysomnogram, also abbreviated PSG. The name is derived from Greek and Latin (polus for “many”, much, indicating many channels, somnus “sleep”, graphein, to “write”).

Polysomnography is a comprehensive recording of the biophysical changes that occur during sleep. It is usually performed at night, when most people sleep, though our Laboratory can accommodate shift workers and people with circardian rhythm sleep disorders and do the test at other times of the day.

It can monitor many body functions including brain (EEG), eye movements (EOG), muscle activity or skeletal muscle activation (EMG) and heart rhythm (ECG) during sleep. The breathing functions respiratory airflow and respiratory effort indicators were added with pulse Oximetry. Polysomnography is used to diagnose or rule out many types of sleep disorders including: Narcolepsy Idiopathic Hypersomnia, Periodic Limb Movement Disorder, REM Behavior Disorder, Parasomnias, and Sleep Apnea.

 Sleep Laboratory offers three types of test:

  1. Diagnostic Sleep Studies/OSA Screening – monitors patient sleep for 6 to 8 hours and determines the severity.
  2. Therapeutic Sleep Studies – use of Continous/Bilevel Positive Airway Pressure machine for patient with sleep disordered breathing.

Combined Sleep Studies – conducted when moderate or severe sleep apnea has been discovered during the first half (two hours) of the study. The second half of the night is used for Continuous/Bi-level Positive Airway Pressure machine. 

What is Sleep Apnea?

Sleep apnea is a treatable disorder wherein a person stops breathing during sleep. It is a common complaint that affects millions of men, women and children but is often undiagnosed despite its potentially life-threatening effects.

Apnea is a Greek word meaning “without breath.” People with apnea literally stop breathing in their sleep. Apnea occurs when breathing ceases for at least 10 seconds for adults or an equivalent of 2 ½ missed breaths for children. With each apnea, the oxygen level in the bloodstream typically drops.

There are three types of sleep apnea:

  • obstructive,
  • central and
  • mixed (a combination of obstructive and central). Obstructive sleep apnea is the most common.

How does sleep apnea interfere with breathing?

As a person falls asleep all the muscles of the body relax. This includes the soft tissues at the rear of the throat surrounding the airway. As this area becomes more flaccid, the tissues collapse into the space meant for air to pass through. The collapse may be severe enough to impede airflow or even shut it off completely. As a result, sleep apnea sufferers stop breathing repeatedly during sleep, as frequently as a hundred times an hour and often for a minute or longer.

With each apnea, the brain receives a signal to awaken the person so that he or she can resume breathing, often making a snorting, choking or gasping sound. Because this pattern of apnea and awakenings occurs repeatedly all night long, it impairs a person’s ability to reach deep, restful phases of sleep. People with untreated sleep apnea are often unaware of the awakenings but only of being sleepy during the day.

I snore. Does this mean I have sleep apnea?

Snoring is produced when air passes through a narrowed airway. It is the most common symptom of sleep apnea. Loud, heavy snoring, punctuated with periods of silence (the apneas), is typical. Although not all people who snore will have sleep apnea, it may be worthwhile to seek consult when it is accompanied by daytime fatigue.

What are the negative health effects of sleep apnea?

  • Untreated sleep apnea can lead to weight gain, high blood pressure and other cardiovascular diseases.
  • Other consequences of untreated sleep apnea include:
  • Falling asleep inappropriately
  • Morning headaches
  • Memory problems
  • Feelings of depression
  • Reflux (backward flow of stomach acid through the esophagus to the mouth)
  • Increased risk for vehicular accidents
  • Nocturia (frequent urge to urinate at night)
  • Impotence
  • Impairment of memory, concentration and work-related performance

Who are at risk for sleep apnea?

  • Other consequences of untreated sleep apnea include:
  • A family history of sleep apnea
  • Excess weight
  • A large neck
  • A recessed chin
  • Male gender
  • Abnormalities in the structure of the upper airway
  • Smoking and alcohol intake

However, sleep apnea can affect both males and females of all ages and of any weight.

The gold standard in diagnosing sleep apnea is the sleep study (polysomnograph), which is usually done at night. The sleep study monitors your level of sleep, breathing and heart rate patterns, and oxygen level. A microphone records snoring sounds while sensors monitor movement. All data are recorded in a computer for analysis.

How is sleep apnea treated?

Treatment depends on the cause/s of airway blockage, age of the patient, and result of the sleep study.

Asian Hospital and Medical Center offers a comprehensive range of diagnostic tools and treatment procedures to help sleep apnea sufferers. The hospital’s highly qualified physicians and state-of-the-art medical facilities guarantee that patients receive the best possible care.

If you feel you or a loved one has bothersome snoring or possibly sleep apnea, timely consult and treatment may avert quality of life and health consequences.
